GUTTER FILTRATION SYSTEMS:
You don’t want debris, leaves, and pine needles getting into your gutters. The only thing you want getting into your gutters is water. Gutter Guard Mercer Island has the best and most reliable Filtration systems on the market. And they all come with our Lifetime Workmanship Warranty and with a terrific product warranty as well. Take a look at what we have to offer:

GOOD: THE LEAF LIEUTENANT
Our Most Economical Gutter Screen!

Each section has a continuous reinforced edge that clips on to the front bead of the gutter. The Drop In gutter screen is virtually undetectable from the ground.

This screen is simple, economical, and it works. No, it is not as high-quality or effective as OUR PREMIER GUARANTEED DEFENSE SYSTEM but it does a terrific job in keeping leaves and large debris out of your gutters.

BETTER: THE NEEDLE SHIELD

NEEDLE SHIELD combines the newest technology with a common sense approach to gutter protection. NEEDLE SHIELD patented stainless steel membrane prevents ALL debris from entering your gutters. The ultra-fine membrane does not even allow the smallest of particles through, keeping out even a grain of sand. The unique design actually vacuums the rainwater through the membrane. Imagine how it will keep out leaves, pine needles and even roofing granules. Along with the rigid aluminum base, NEEDLE SHIELD will continue to keep your gutters clean while you relax year after year. NEEDLE SHIELD is available with new gutters or can be installed on your current gutters.

The NEEDLE SHIELD base is covered with a fine stainless steel membrane that prevents any particle larger than 100 microns (a grain of sand) from entering your gutter. A single pine needle won't get past Gutter Grate!

The NEEDLE SHIELD membrane has a clog resistance rating of "9" (10 is the highest) it is highly unlikely that dirt, scum or pollutants will ever clog NEEDLE SHIELD! (Most screen, filtration type, and reverse curve gutter products are very susceptible to debris penetration, or to debris lodging within the products' water receiving areas, and normally achieve no better than a clog resistance rating of 1 to 4)

NEEDLE SHIELD aluminum body with stainless steel mesh will never be affected by the heat or sun. The life expectancy of the NEEDLE SHIELD membrane is over 20 years.

BEST: OUR PREMIER GUARANTEED DEFENSE SYSTEM

Construction:
This system consists of two components, a perforated aluminum channel and 316 stainless steel mesh. The stainless steel mesh is glued into grooves along both sides of each 5 foot aluminum channel section. It installs on any existing gutter. It was designed that way! This system’s specifications were designed so that it simply slips under the roof shingles and fits snuggly to the front lip of your gutter.

Aluminum Channel Frame:
Our extruded aluminum support frame is anodized to further protect itself from the environment. The anodizing process converts the aluminum surface into an extremely hard, durable, corrosion resistant, long-lasting aluminum oxide finish. Anodizing also responds favorably to current governmental regulations because it is one of the most environmentally friendly industrial processes. Since this process is a reinforcement of a naturally occurring oxide process, it is non-hazardous and produces no harmful or dangerous by products. Anodized aluminum is used around the world as highly durable exteriors in commercial buildings such as one of the world’s tallest buildings, the Sears Tower in Chicago, Illinois. Other revolutionized uses are in scientific instruments, home appliances, and satellites in space for harsh environmental protection, staircases in skyscrapers and a host of other uses.

Stainless Steel Mesh:
The super-strong type 316 stainless steel mesh allows more than 150 inches of hourly rainfall to filter through to your gutter. Type 316 is molybdenum-bearing austenitic stainless steel which is more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium nickel austenitic stainless steels such at types 302 and 304 or any other standard stainless steel alloys. The 316 alloy offers higher creep, stress-to-rupture and tensile strength at elevated temperatures. It also resists attack of marine and corrosive industrial atmospheres which makes it an ideal component for this product. 316 is widely used in the food, marine and medical industries.
