The need to prevent the spread of germs has always been a major concern. Research indicates that a copper surface is more effective at preventing the spread of germs than stainless steel. Copper has a 2000 year history of antimicrobial applications in a multitude of cultures. More recent research has sought to determine uncoated copper's effectiveness in stemming the proliferation of infectious disease. At the University of Southampton in the U.K. research studies have shown that many common disease causing microbes such as E. coli, Aspergillus niger (black mold) and Influenza A, die within hours on copper surfaces. The Influenza A family of viruses includes the problematic Avian flu and swine flu strains and copper can help contain a flu. Even deadly antibiotic resistant bacteria associated with infections such as MRSA (Methicillin Resistant Staphylococcus Aureus) die within 1.5 hours on pure copper. On stainless steel and plastics, typically used for food-processing hardware, pathogens survived unabated for days, sometimes more than 30 days. There is enough solid evidence to put man's oldest metal to work throughout the world to help protect us from infectious disease. Tested copper alloys, such as brass or bronze also offer increased protection over non-copper containing materials such as stainless steel, painted surfaces, wood and plastics, although not nearly as effective as pure copper surfaces.
Some fairly common and obvious uses in the home for elegant yet functional copper home decor include copper kitchen sinks, bathroom copper sinks, copper bar sinks, food prep sinks, copper basin, copper vanity sink, copper door knobs, copper handles, copper range hoods, copper planters, copper pot racks, copper bowls, copper sheets or copper tiles for making copper countertops and copper sink backsplashes, copper tabletops, copper chair arms, copper wall plates and switches, copper light canopies, copper ceiling fans, copper vents, copper louvers, copper cookware, etc. There are germ killing copper facades available for refrigerators, dishwashers, freezers, ice-makers, ovens and ranges. There are copper-plated kitchen appliances, copper vases, copper sculpture, copper accent pieces, copper planters, even copper flowers. Copper bathroom fixtures and copper kitchen appointments may be the most obvious places to most benefit from and utilize copper's antimicrobial power, yet manufacturers are now focusing in on all home furnishings and furniture as well as laptop, remote control and cell phone cases. The ceiling for new copper surfaced products is sky high, especially considering copper's aesthetic qualities, durability, long lifespan and green copper work as eco-friendly too.
Galvanic Corrosion is an electrochemical process which occurs when dissimilar metals are in contact with each other in the presence of an electrolyte, most commonly being moisture and oxygen. For example rain water and salt water make especially good electrolytes. An electrolyte could be any non-metal matter that will conduct an electric current and are predominantly liquids or moisture. Every metal has been rated for nobility and then placed on galvanic scales according to nobility. Basically nobility is a measurement of the resistance to corrosion, especially of one metal contacting another metal. Metals that are the least noble means they are very anodic, electropositive or high potential and will corrode most easily. Whereas metals that are the most noble, means they are highly cathodic, electronegative or low potential and will be the most resistant to corrosion. The most corrosive effects will occur between metals from the opposite ends of the galvanic scale or ranking of nobility. This difference in electrical potential between two or more metals causes galvanic corrosion. Dissimilar metals in contact with each other in the presence of an electrolyte causes current to flow through their points of contact at the expense of the metal with the higher potential or less nobility. The much less noble metal is gradually consumed in the Electro-chemical reaction and will deteriorate or wear away as the metal ions migrate away from the very anodic metal to the more noble cathodic one. The more noble metal's corrosion resistance actually increases from this transfer of ions to it from the less noble metal, while the other metal is gradually getting consumed. Below is an abbreviated galvanic scale showing ranking of the most common construction metals from the least noble up to the most noble in a normal construction setting where both moisture and oxygen are present.

Since
dissimilar metals in contact with each other in the presence of oxygen
and moisture will result in the less noble metal being corroded or
eaten away the more noble one, contact between dissimilar metals should
be avoided. For example, copper as one of the most noble of metals
should be kept separated from less noble metal such as aluminum and
galvanized steel. If contact between dissimilar metals cannot be
avoided, their surfaces should be insulated as much as possible at the
least with a non-metallic, non-conductive coating, such as bituminous
or zinc chromate primers or paint. Separating the dissimilar metals
with tape, gaskets, waterproof membrane, sealants or other
non-conductive material that does not absorb and hold moisture can be
used effectively. Care must also be taken to avoid the liquid wash run
off or discharge from the drains from noble metals to less noble ones.
For example rain water run off from a copper roof going into aluminum
gutters and downspouts will result in traces of copper salts in the run
off wash accelerating corrosion of the aluminum. Additionally, the use
of galvanized nails, screws, flashing or drip edge on copper roofing or
copper gutters should likewise be avoided as such less noble fasteners
and metals will corrode rapidly. While rain water is a good electrolyte
so too is high humidity or moisture laden air especially when it
contains a high concentration of corrosive acids as is typically found
in larger cities or near industry. In industrial or heavily populated
areas, harmful electrolytes are formed by the
absorption of gases by rain and fog to form acids and salts, while in
coastal areas a saline
electrolyte is formed by the combination of salt with the moisture
laden air.
As
copper has one of the highest galvanic numbers or nobility of
construction metals, copper will not be harmed by contact with any of
the common metals. However, copper will promote corrosion of other less
noble metals if placed in direct contact with them. Copper can be used
most appropriately with lead, tin, lead-tin solder or stainless steel
under almost any circumstance. The primary metals of concern in terms
of galvanic corrosion contact with copper are aluminum and zinc. Large
differences in the thermal expansion rate between copper and these
metals may cause additional problems. Also avoid using copper and some
brass fasteners with aluminum, zinc and most ferrous metal. Paints or
coatings that are used for isolation must be compatible with both of
the dissimilar metals. The bituminous or zinc chromate primers and
paints can be used between copper and aluminum surfaces. These same
coatings or a red lead primer can also be effective in separating
copper from iron and the other ferrous metals such as galvanized steel
or mild steels.
Another type of corrosion called erosion corrosion is caused by the flow of acidic water concentrated into a very small area. While especially true for the least noble and most corrosive of metals, but capable of affecting all metals, acidic water allowed to concentrate on a small area, for example rain water from a large area like a roof diverted towards a flashing, valley or gutter can cause erosion corrosion. Also acidic water or liquids pooling on metal surfaces or trapped without air circulation between roofing or sheathing can quickly corrode the metal. Solution is to eliminate such pooling, maintain air circulation underneath metal roofs or between inert roofing material and drip edge, valleys and flashing. Another solution is to use replaceable reinforcing insulative strips between the inert materials and metal. Raw zinc and aluminum especially are susceptible to prolonged contact with acidic moisture, as for example the underside of a zinc roof. But care should be taken even with copper and stainless steel. Copper and zinc possess a superior property in that both will gradually develop a long term protective patina that helps guard against such corrosive effects for a very long period of time providing initial safeguards are exercised such as drying out provisions or temporary coatings.
*Note: Galvanic
chart rankings involving sea water immersion and low oxygen conditions
will vary somewhat - the more typical nobility given here is for land
based construction.
Rain gutters sometimes do not get as much thought behind their selection as other architectural features of a home or commercial building. Customary gutters often employed on buildings might even be rather drab and sometimes an afterthought. Rather than accentuate and enhance the building's architecture some gutter choices if not just dull may actually detract from the appearance of the home or building and be very unappealing. Yet barring wide overhangs and a steeply graded slope away from the building, gutters are essential for draining rainwater runoff from a roof away from the building protecting overhangs, eaves, walls or siding, windows, doors and assist keeping the foundation, crawl space or basement of the structure dry, thereby guarding against mold, rot and staining. Gutters also help prevent erosion of the top soil and landscaping around a building and shield people, walkways and entrances from sheets of falling water. Yes, becoming aware of all the available choices and features of guttering makes you a better wiser consumer. It also gives you an opportunity to choose a rain gutter system that doesn't just blend nicely into your building's architecture but actually enhances and upgrades the features, appearance and curb appeal of your real estate investment. Possibly you may start seeing guttering in a whole new light, and in planning and choosing your new gutters wisely, you are certain to be rewarded time after time again.
Rain gutters run the gamut from your run of the mill, same old - same old, aluminum K-style ogee gutters with rectangular corrugated downspouts, which are staples in some neighborhoods on those cookie-cutter homes, to the high end gutters purposefully designed to enhance a building's architectural features such as your integrated guttering or wood box gutter and those premium, elegant half round copper gutters and zinc gutters. There are still more gutter material choices including plastic or vinyl gutters, galvanized steel, galvalume and stainless steel gutters. As you might expect there is a wide range of pricing from your low end cheap vinyl gutter on up to that pricey redwood and stainless steel guttering. Cost is definitely going to be a big factor in many people's decision making on gutter choice. Assessment of your true cost extends beyond simply viewing a gutter system's initial purchase price and also includes analyzing the longevity of the guttering, plus any maintenance time and cost involved during the lifespan of the gutters such as: repairs, re-caulking, re-painting and partial or total replacement of a deteriorated gutter system. Another often overlooked cost is how the guttering choice will affect your real estate value. A poor guttering choice will detract from the building appearance and value, a typically common or acceptably sensible choice will hopefully maintain and uphold the property value and a visionary or astute choice will increase the real estate attractiveness, curb appeal and property value. A final consideration is the growing number of concerned people out there who also appreciate making the most environmentally green and eco-friendly choice.
Gutter Materials and Cost
Vinyl Gutters -
Frequently a choice for your do it yourself price conscious people,
these plastic or vinyl gutters oftentimes in plain white and sometimes
in assorted colors are rust free, easy to trim or cut to size and are
relatively cheap initially. Though 10 foot gutter sections may only run
$3 to $5 at discount home outlets, with all the connectors, hangers,
brackets and downspouts figured in they will cost you more like $3 to
$5 per foot installed. Vinyl gutters can get brittle with age and
exposure to the elements and may not have the strength to stand up to
large amount of snow, ice, gale force winds and weight from a ladder or
person climbing on to a roof. Vinyl also expands and contracts more
than metal and can be problematic. Mostly they frequently look cheap,
detract from your property's appearance and have a relatively short
lifespan to boot. PVC or poly vinyl chloride gutters are not a very
green or eco-friendly choice because of their short life and
environmental health concerns. The Center for Health, Environment and
Justice (CHEJ) termed PVC plastic as one of the most hazardous consumer
products ever created, dangerous to human health and the environment
throughout it's life cycle. When it is produced or burned PVC releases
dioxins, potent synthetic chemicals that cause cancer and harm the
environment.
Galvanized Steel Gutters - Steel coated with zinc to inhibit rust, was a common choice, especially before aluminum gutters appeared on the scene, as galvanized gutters are fairly strong and can stand up to ladders, fallen branches and weight unlike cheaper vinyl gutters. Galvanized gutters are also stronger and less susceptible to dents and damage than aluminum. Galvanized steel gutter pricing may run only $4 to $9 per foot installed and are seemingly a economical and practical choice. Yet even thick galvanized gutters will eventually rust through despite most of them being painted. Paint grip steel guttering is still galvanized steel that has been given a phosphate bath adding some to the corrosion protection but primarily providing a surface with better adhesion for paint. There are usually many color choices provided and different qualities of paint available. Galvanized gutters have to be maintained, inspected for cuts, metal exposure deterioration and re-painted during their practical life ranging from 7 to 20 years, depending on how corrosive their locale is and how well they are maintained.
Aluminum Gutters - The most popular choice in gutters since they appeared on the market, aluminum gutters are rust free avoiding that concern with steel, iron and galvanized gutters. Aluminum is also lightweight making it easier and cheaper to work with. Aluminum gutters typically range in price from $5 to $9 per foot installed. Exposed to the elements however, aluminum will oxidize and wear quickly so aluminum is given protective coatings and paint. Just as with galvanized gutters, aluminum gutters need to be maintained and inspected regularly. Paint coatings have improved so during aluminum gutters typical useful lifespan of 25-30 years most paint coatings usually hold up barring scratches or damage to the paint. Aluminum gutters and downspouts are not as strong as steel gutters, especially the thinner offerings and can dent easily from traffic, branches, ladders, etc. Aluminum has a high rate of thermal expansion and contraction which can sometimes present problems especially in corners and seams. Gutter sections and terminations are typically caulked and as such the caulking will also have to be inspected and re-caulked. As with galvanized steel, there are usually many standard color choices available or custom paint matching can also be done at a higher cost. To have a different look than the same old common K-style aluminum guttering with rectangular corrugated downspouts, you can also obtain aluminum gutters in a more elegant half-round gutter shape and with smooth surface versus corrugated square or round downspouts. Hidden gutter hangers can be used or better yet decorative gutter and downspout brackets and a decorative leader head will improve appearance greatly, distinguish and enhance your home. Using thicker and so called primary aluminum material will add some to the strength, better able to withstand wear and abuse but still not up to the level of copper and steel.
Galvalume Gutters - In response to some of the limitations and disadvantages of galvanized steel gutters and aluminum gutters, galvalume gutters appeared on the scene. Galvalume is steel coated with a mixture of 55/45 per cent aluminum/zinc, resulting in a metal about as strong as galvanized steel but the with long-term rust and corrosion resistance more like aluminum or 2-4 times longer than plain galvanized steel. Galvalume can also be used as is without any paint and has a bright gray metallic appearance for about a decade gradually turning a dull weathered gray for the last 2-3 decades of it's typical lifespan. Processed galvalume can also be painted different colors just like aluminum gutters and while galvalume gutters cost a little more than either aluminum or galvanized steel gutters, galvalume not only will last longer, but is much stronger than aluminum and doesn't have the temperature expansion rate issues as does aluminum. Unfinished galvalume additionally enjoys the more green and eco-friendly avoidance of any kind of painting or coating.
Zinc Gutters - Zinc gutters have been popular in Europe for decades but have been slow to take hold in the U.S. Zinc guttering is usually made from an alloy of 99.5 percent zinc with small amounts of copper and titanium added. Similar to copper, zinc is usually utilized in it's raw unpainted state and will develop a protective patina that protects the zinc gutter from weathering and corrosion. Weathered zinc has an attractive matte gray look somewhat similar to pewter that eventaully turns a bluish gray and is increasingly being incorporated into architectural designs that promote that look. Zinc gutters when the natural patina forms properly can have a very long lifespan typically somewhere between 40 and 80 years depending on environment. Zinc gutters may run $15 to $20 per foot installed, which is much more than aluminum gutters initially, but zinc gutters have over twice the lifespan, require no paint and very little to no maintenance. Zinc gutters being a premium gutter usually have more care taken in the installation, including typically riveting and soldering the seams and corners, providing more reliability and often less leaks and water damage. Unpainted zinc gutters also do not have VOC's released into the environment from any coating or painting process which some gutters require, so with that and their long lifespan, zinc guttering is considered very eco-friendly and green. Zinc gutters main issues deal with thermal expansion, restrictive gutter forming and installation, including sensitive soldering and cold temperature (below 45 degree) working restrictions. With accommodations and extra care taken, zinc gutters are not only a viable option but are one of the better ones.
Stainless Steel Gutters-
Stainless steel is a steel alloy containing chromium which gives
stainless steel it's rust proof and shiny properties and is familiar to
everyone as it is widely used in kitchens and for eating flatware.
Stainless steel is one of the strongest guttering materials as are all
the steel based types and is also one of the most durable and longest
lasting with a lifespan typically between 50 to 70 years. Stainless
steel gutter systems work great where the gutters and downspouts are
subject to commercial, abusive and high traffic conditions. If you are
not enamored of the shiny, metallic look of stainless steel or the
maintenance, cleaning and polishing to keep that look, there is a
copper plated stainless steel called CopperPlus having copper's
changing earth tone colors and tin plated stainless steel products such
as Ugitop which replace regular stainless steel's shiny look with a
matte gray surface. Similar to zinc and copper, the durability,
weathering ability, long life and elimination of painting and coatings
make stainless steel very eco-friendly and a good value where stainless
steel's extra strength is needed even with it's high initial cost of
about $18-22 per foot installed. Like zinc and copper, in the long run
it can be less costly than short-lived products.
Copper Gutters
- Copper gutters have long been considered the ultimate in guttering
and for good reason. Copper gutters have always been the most elegant
and aesthetically pleasing and also the most durable and longest
lasting of all gutter types. It is not uncommon for copper gutters to
have a lifespan of 60 to 90 years, up to triple that for aluminum.
Copper guttering like zinc gutters are mostly utilized in their
natural, unfinished state as copper develops it's own distinctive,
protective patina through the years. Copper performs great in
industrial cities, coastal and marine environments. Copper's protective
patina gives it the ability to ward off corrosion and it's long wearing
character. Copper patina varies by climate but generally copper starts
out a bright salmon copper and gradually turns brown, then shades of
reddish brown, grayish brown, greenish brown then finally a variegated
light pastel green after 25 some years. The rich changing earth tone
color palette is one of the prized features of copper. Like zinc
gutters, copper guttering is riveted and soldered, so there are rarely
any issues with leaks or repairs. Copper gutters will definitely
upgrade and enhance any home or commercial building and add true curb
appeal and value. While copper gutters can cost $15 to $24 per foot
installed new, with copper gutter's super long life, little to no
required maintenance, no painting, no leaks and 100% recyclability
while retaining up to 95 per cent of raw copper's value, a great case
can be made for choosing copper gutters. Environmentally speaking,
copper is considered one of the greenest and most eco-friendly
materials available and copper's total environment cost is lower than
initially cheaper materials. Total environmental cost includes the
costs of raw processing, manufacturing,
installation, maintenance, re-cycling and multiple replacement costs,
so
durability and longevity do factor in greatly. For people that want to
enjoy the durability, longevity, value and environment friendly nature
of copper but would prefer gray earth tones, lead coated copper is
available with the same same attributes as copper other than color. For
those that would prefer something other than a lead coated copper there
is now also a zinc-tin coated copper option available called Freedom
Gray, which retains all of copper's advantages, while providing
architects, designers with a gray earth tone to work with. Lead coated
copper or Freedom Gray offer advantages over zinc gutters in being
easier and more versatile to form, less restictive and easier to
install, while being more reliable and durable in any weather situation
and longer lasting. Copper gutters may typically be seen with
decorative gutter hangers, smooth seamless round copper downspouts and
decorative downspout brackets and oftentimes a decorative, distinctive
conductor head or leader collector box. So configured copper gutters
will enhance a home to where they are seen analogous to valuable
jewelry and accent pieces and always at home with the finest
architecture.
Integral or Wood Gutters - Gutters integrated or built into a homes eaves were more popular decades ago as are hanging wood gutters. Both integral and wood gutters have always had problematic issues such as waterproofing, weathering, leaks, rotting, maintenance, painting or staining, durability and water damage. Oftentimes, the inside of a wood gutter and downspout was lined with a metal such as copper to protect the wood, like a gutter in a gutter. Wood gutters are really not installed so much anymore outside of restorations and wood gutters pricing can easily run from $15 to $24 per foot or more depending on type of wood, lining and workmanship involved. With integral and wood gutters, frequent inspection and maintenance are definitely recommended to help prevent leaks from causing possible water damage to roof, fascia and walls.
Although stainless steel, zinc and copper gutter installed prices appear significantly higher than for galvanized steel and aluminum gutters, this is not because raw material cost for these premium metals is so much higher. The higher installed cost for these premium gutters is primarily due to the cost of additional labor and better materials used in what is a more involved and better installation. Gutter seams and joints are most always riveted and soldered in the best installations rather than merely caulked and overlapped. This much more labor intensive operation provides stronger and more leak free joints over the lifespan of the gutter. Better work and tolerances in corners, miters and seams increases cost but results in a more trouble-free and better looking installation. This is the norm and expected by customers of premium gutters. If aluminum and galvanized steel gutters were installed in a similar fashion as zinc and copper gutters, there would be a much smaller price difference. Thicker gauge aluminum gutters with a higher quality paint job such as Kynar is significantly higher quality and also higher cost than typical thin aluminum gutters with plain baked on paint finish that are much more typical. Thicker metal and better paint result in a better gutter that withstands more abuse and lasts longer. Using better materials and more meticulous aluminum gutter installations, though at much higher cost, would lessen such commonly seen occurrences as drooping gutters, buckled gutters, badly faded gutters, misshapen or bent gutters, leaking gutters, peeling or flaked off paint. True for most any product or service, you certainly get what you pay for and the same applies to rain gutters.

Rain chain
or "kusari doi" in Japanese, have been used for centuries on Japanese
homes, temples, public and commercial buildings as a functional yet
lovely alternative to our traditional rain gutter downspouts. Rain
chains have also been incorporated for their decorative beauty into
many tranquil Japanese rain chain gardens. Today rain chain have become
more well known outside Japan and increasingly prevalent around the
rest of the world. Rain chain used in rain water drainage are typically
hung from a roof's rain gutters or roof scupper box (leader head),
taking the place of downspouts or gutter downpipe. Rain chain like the
name implies can be as simple as chain links or a variation of chain
loop styles. Rain chain can also be a visually pleasing string of cups
or funnels, most often shaped like flowers or bells and hollow with
open bottoms. Pictured below in order of left to right, top to bottom,
are the simple link rain chain, single loop rain chain, rotated double
link rain chain (or double loop), Japanese rain chain bells, Tulip rain
chain, Bluebell flower rain chain, Lily rain chain and a rustic
Scalloped rain chain. All the rain chains pictured here are fashioned
from heavy weight pure copper. Copper Rain Chain
is the preferred choice for it's timeless elegance, aesthetics,
weathering ability, durability and natural beauty of copper's ever
changing patina throughout the years.

Roof Scupper Box Rain Gutter Leader Head
Water from a rain gutter outlet or from a roof scupper can empty directly into a leader head or rain collector scupper box and you can then attach a rain chain directly to the leader head or scupper box outlet. Outlet size on leader head and rain collector scupper box can be custom sized typically from 4 inches down to 2 inches to match the desired diameter for use with your rain chain. You can install a bolt across the bottom of the leader box outlet about an inch from the bottom opening and then attach the rain chain directly to this bolt. If your are not using leader heads, then mount rain chain using hidden gutter hangers and U-bolts.
Gutter gardens are receiving much buzz over the internet and are a good
approach to generating fresh produce or a colorful display of flowers
around your home. A gutter garden is especially ideal when space is at
a premium or if you wish to have a tidy and more ergonomic gardening
setup. Nothing is better tasting and more satisfying than freshly
picked produce for that awesome salad, fresh salsa and a plethora of
other healthy vegetable dishes. Gutter gardens are essentially akin to
planters that hang from your house at a convenient height and are
typically fashioned using some form of home guttering to serve as your
planter. This article discusses and compares several types of
commercially available gutters that are good options for use in a
gutter garden. Then we will explain exactly which components you will
need and how to assemble your very own gutter garden. I do not know who
first came up with the idea for a gutter garden, probably someone a
long time ago and it was never publicized. Now with power of the
Internet word gets around. I did find an article from Martha Stewart
Living dating March 2006 that called them "Garden Pots" and they used
copper gutters stacked in several tiers to form their gutter garden.
They were growing hanging ivy in them to form a living screen off of a
porch, but could just as easily be growing flowers or produce in them.
Hanging your gutter garden as they did with chains is another option to
mounting on a wall, just make sure your chains, anchors and supports
are all robust and secure.
Re-using old guttering or buying cheap aluminum or plastic guttering are tempting options but may perhaps not be the best option. It is recommended you stay away from any kind of painted, rusted guttering or lead coated guttering for obvious health reasons if you are growing produce. Many plastics have unhealthy emissions and plastic gutters can also break down from the weight, UV sunlight and trowel work. It is best to use a gutter made from a pure metal that does not have any chemicals or paint applied, does not corrode or rust over time, is durable, long lasting, naturally weathers well, is aesthetically pleasing and is a genuinely attractive feature of your home. Steel and aluminum are relatively low priced but most varieties require some type of coating to resist rust and corrosion and coatings oxidize, scratch, are not durable, long lasting and mostly unhealthy too for a gutter garden. Galvalume is a zinc-aluminum coated steel that is a better candidate than either steel or aluminum alone, combining the corrosion and rust resistance of zinc and aluminum with the strength of steel but with an industrial looking gray metallic appearance and you would probably be tempted to paint this material. Three even better choices for your gutter garden are zinc, stainless steel and copper. Everyone is familiar with the appearance and attributes of stainless steel and it is a viable option. Stainless steel does not rust providing it's surface is not damaged and it is generally considered a healthy, sanitary material. Stainless steel's shiny appearance may be attractive or it may not blend in or complement your home's exterior. Pure zinc is a viable, healthy option that is durable, weathers well and zinc develops an attractive protective, grey patina that is somewhat pewter like though zinc is priced higher than galvalume and stainless steel. Then we have pure copper which may be the best choice for a multitude of reasons: copper has proven itself for centuries to be the most durable and longest lasting metal; copper weathers extremely well, forming a protective attractive patina; requires little to no maintenance; copper is attractive, aesthetically pleasing, elegant and complements most home decor well; copper is EPA approved antimicrobial, germicidal, antibacterial and fungicidal; copper is a key nutrient for plant life; copper is considered eco-friendly and is a green building material. These are all attractive and most desirable traits for use in your gutter garden. Copper although being our highest rated choice also has the highest initial cost of all the metals and metal alloys mentioned above. Copper's many and unique advantages, help justify it's premium cost, especially considering the relatively short lengths required for most gutter gardens, which put copper gutters' premium price within reach and affordability.
Once
you have decided on the material for your gutter, you will then likely
choose between three common styles of gutter: K-style gutter,
half-round gutter and box gutter. A box gutter
will give you the most volume with which to garden with, and as it's
name suggests, it has a rectangular box appearance or if you like a
plain box planter. K-style gutters are probably the most common
residential gutters used in the U.S. and are somewhat boxy as well,
though with a angled stepped front for a little more pizzazz. Half
round gutters do look just like they sound, like half of a round
cylinder or pipe and half-round gutters also have the most elegant
appearance of all the various gutter types. There are also quarter
round gutters which also are very attractive with their curved front.
Quarter round and K-style gutters are generally available from 5 inches
to 8 inches wide, half round gutters usually from 5 inches to 10 inches
wide and box gutters are usually manufactured to size. Custom widths
are also available through Rutland Gutter Supply.

Additional Tips:
Avoid applying any chemicals or paint to the inside of your gutter garden for healthier plants and produce. If you absolutely must paint to achieve a desired color match, then do so only on the outside surface. Stainless steel will need to be cleaned and polished occasionally to keep it's appearance while zinc and copper weather naturally and keep their beautiful, elegant appearance throughout their lifespan. Copper can be waxed regularly or even coated with a clearcoat or lacquer if you wish to keep the shiny new copper appearance but again do not apply any coating to the inside to avoid chemicals and to take full advantage of copper's natural germicidal, antimicrobial and fungicidal properties. Also any wax or coating is temporary and needs to be re-applied. The natural copper patina howver needs little to no maintenance When copper weathers there is a natural patina that forms on it's surface which serves as a protective coating and the patina does not affect copper's antibacterial properties. The copper patina changes color with age, progressing from a shiny salmon color, to reddish shades of brown, brown, greenish brown and finally a light green pastel color. The outside patination process can also be accelerated if desired by applying selective accelerants. Copper is revered and prized for it's graceful, elegant appearance and gradually changing color throughout it's very long lifespan. Approximate copper weathering color chart is illustrated below. If you desire drainage for your gutter garden, you may either choose to drill a few small holes sparsely across the entire length or have your guttering fabricated with rain chain style taps every few feet along the length.
For the framework we will be using aluminum tubing, plywood sheathing and waterproof membrane. We begin by precisely cutting square aluminum tubing to size and bending the tubes using a roll forming machine to form the base and the many vertical support cross members. A partially completed aluminum frame is shown below.
After
all the plywood sheathing panels have been securely fastened in place
with self-tapping screws, we then apply to the partially completed dome
a self-sealing waterproof membrane, taking care to completely seal the
dome. After the membrane is in place, we draw guidelines and begin
carefully attaching the hand-cut copper tile to the dome and to each
other. The copper tile have been designed to interlock securely with
each other and we use copper ring shank nails to fasten them to the
plywood.
