Once you have cleaned your roof, Shingle Shield Roof Protector zinc strips should be installed to inhibit the return of algae, fungus, or moss. Stains caused by pollution, pine pollen, dirt, etc., will need to be re-cleaned as deemed necessary to maintain your roof’s neat appearance.

Yes. Shingle Shield Roof & Deck Cleaner effectively cleans away stains of algae, fungus, molds, mildew, dirt, pollution, pine pollen, berries, etc. Since it contains no bleach, it will restore the natural color to the wood. Wood shingles get slippery when wet, however, so wait until they are completely dry before walking on them.

When properly mixed and applied according to the label directions, it will not hurt your plants. As a precaution, it is wise to rinse any overspray off of your plants to avoid spotting.

Absolutely! Shingle Shield Roof & Deck Cleaner is the perfect solution to restoring the appearance of wood decks, gazebos, fencing, or porches. It will not lighten the wood’s color (including cedar and redwood) because it contains no bleach. It is also ideal for cleaning most non-oil type stains from concrete driveways and sidewalks. Properly follow all directions on the label.

No. The zinc oxide it releases is microscopic and absorbed by the shingles. It is possible, although unlikely, that the attachment nails will leave rust stains. We recommend the use of quality, double hot-dipped galvanized roofing nails, such as Mazeä brand.

In most cases, one row at or near the ridge line will be sufficient to inhibit the growth of fungus, moss or algae. On roof slopes longer than 20’, or roofs with a severe or persistent problem, install a second row halfway down the roof. While we cannot readily endorse any other installation method, you may be able to attach Shingle Shield by using a roof mastic (adhesive).

No. Shingle Shield will quickly weather to a pewter gray. In addition, since only 2" of it are exposed it is difficult to see from the ground. Remember, the alternative is an unsightly, badly stained roof.

No. If we were to apply color to Shingle Shield it would be unable to release zinc oxide – the active ingredient that protects your roof.

Based on the thickness of the zinc that is Shingle Shield, it is reasonable to assume that it will remain effective in excess of 20 years. Climate may also be a factor in this estimate.

Shingle Shield is EPA approved and should be used as directed in a manner consistent with the provided instructions, and as such is considered safe. Zinc is an essential element of the human body. It can be found in vitamins, and as an additive in breakfast cereals.

Yes. But be cautioned that Shingle Shield is designed specifically for use with three tab shingles. The installer assumes complete responsibility as to how to attach the product to a wood roof. The primary objective is to have rain water run over Shingle Shield, then onto the areas affected by fungus, moss, or algae.

This is a question about dissimilar metals corrosion. Zinc and aluminum are adjacent on the electro-chemical scale. The farther apart metals are on the scale the greater the likelihood that they will have an affect on one another. The fact that zinc and aluminum are so close indicates that there would be little problem, even if they were to come in direct contact with one another on the roof, which they should not.

A metal roof will last at least 2-3 times longer than a regular roof. An asphalt roof needs re-roofing every 12-20 years, while a metal roof will last 40 years and beyond. Other roofing materials begin to decompose as soon as they are exposed to the elements. A metal roof will never decompose and will hold its good looks for decades. Most metal roofs come with up to a 50 year warranty. Metal roofs have actually lasted over 100 years in many instances.

Generally, one (1) gallon will clean 2,000 square feet when mixed at a ratio of 9:1 with water. Two (2) gallons is usually sufficient to clean the average roof.

When rain water comes in contact with Shingle Shield Roof Protector, a fungistat and effective drying agent is released, zinc oxide. This agent is meant to inhibit the growth of algae, fungus, or moss – not kill it.

Classic Products warrants the Kynar finish for 40 years. The aluminum shingles will probably outlast the house. The oldest aluminum roof in the world was installed in 1880 on the Chief Secretary's Office Building in Sydney, Australia and is still in sound condition.

Yes, you can walk on a Rustic Shingle roof. The deep grooves and woodgrain pattern provide the shingles with the strength needed to sustain normal roof traffic. You must step on the upper half of the panels where they taper to rest on the roof deck. If, for some reason, the roof is expected to have a lot of traffic, Classic Products offers an optional urethane backer molded directly to the shingles. This urethane, a top grade insulating material, is self-extinguishing and U.L.

Two layers of shingles are allowed on your roof without a permit. If you take off the shingles down to the sheathing and sheathing must be replaced a permit is needed.

The life span of a cedar shingle roof depends on many factors: product used, thickness, slope, maintenance, application and climatic conditions are the most important. Cedar roofs can last 100 years. Silver Creek's products are warranted to last a minimum of 20 years and Silver Select Heavy's are warranted to last 50 years. (See warranty section.)

The smart homeowner buys roofing on an annual cost basis. First, the total installed price is determined. Then other factors are determined, such as how long the new roof will last, how much it will save in energy costs, how well it provides wind, water and fire protection, how much maintenance it will require, and how well it is likely to survive a severe storm.

Gutter-Shield is easily customized to fit any home. Technicians will advise you on the best installation procedure for your home.

In many cases, Met-Tile can be installed directly over an existing roof. Ask your roofing contractor for further information. Though Met-Tile costs more "per square" than shingles, it is very cost- effective over time because it outlasts conventional roofing and requires little maintenance. After a number of years, panels can be repainted if desired, often eliminating the need for a far more costly roof replacement.

Answer. That depends on the slope of the roof and the direction of the building. The composition roof should last between 20 and 30 years, depending on the weight of the shingles and proper maintenance (20-year, 25-year, 30-year shingles are rated by weight).

Yes. Grace Select meets the key performance standards prescribed by ASTM and ICBO for fully adhered underlayments in severe climates. (See ICBO Evaluation Services Report No. 3997).

One of the benefits of steel roofing is that is lightweight, which allows it to be installed over existing roofing material. Local building codes and your roofs substructure integrity must be addressed to reveal this answer.

We use high grade 35-50 year warrented shingles. Each Triangle is shingled separately. The point down triangle bottom edges overlap the point up triangles by 6". We do not use any ridge cap shingles. We do not use any caulks or sealants which usually fail in 3-5 years. We use ice & water shield membranes at the top of the dome, in valleys and around skylights. We have hundreds of domes and they DO NOT leak, period.

Grace recommends that the Grace Ice & Water Shield is extended a min. of 24"" beyond the inside face of the exterior wall line of a building and should extend from the eave above the highest expected ice damn.
