home from weather, and the second is that it should look good for at least a few decades.
Unfortunately, some roofs develop unsightly black streaks and stains below the roof line. If this happens to your roof, consult Toms River roofing professionals to plan a way to correct this problem.
Many people believe that the black is due to the tar or dirt in the shingles or perhaps as a result of an adhesive or even a defect in the shingles. This ugly substance is actually due to blue-green bacteria known as Gloeocapsa Magma. The bacteria are often mistaken for algae growth, probably because of their blue-green coloring.
The bacteria spread through the air, and they’re quite common in areas with high humidity. Recently, these stains have spread more rapidly in many regions, and one explanation is that rising humidity makes an ideal condition for its growth.
Another reason is that fiberglass shingles that were used extensively a few decades ago are made with limestone filler in the asphalt material. The limestone holds both moisture and the organic material favored as food by the bacteria for longer periods. The felt material used underneath the shingles also holds moisture in the system much longer.
Homeowners can get rid of the stains temporarily.
Chlorine bleach cleaning usually produces a dramatic though temporary effect. Oxygen bleach cleaners do not work as immediately or to such a great effect but are less harmful to the environment. A mix of trisodium phosphate (TSP) can also be used to clean the stains. Some manufacturers offer specific commercial products to do the job, and you can clean your roof yourself or hire a roofing professional.
The most effective method of eliminating the unsightly stains, however, is the prevention of the growth. There are several ways to do this, and metals are the most effective natural bactericides and algaecides in nature. Several shingle manufacturers offer copper granules mixed into their shingle products. Copper is an excellent material to prevent both bacterial and algal growth. Specifying these shingles when re-roofing can prevent those ugly black stains during the life of the roof. Once the stains are cleaned, you can install a strip of copper or zinc-coated metal on each side of the roof just below the ridge lines.
There is no reason for a roof to have ugly black streaks. The unsightly discoloration can be cleaned and prevented from recurring by using the right immediate and preventive treatment. The experts at Fortified Roofing, Toms River roofing contractors can answer your questions about new roofs or skylights.
Common roofing term explained by Fortified Roofing, Toms River roofing contractors:
Zinc-coated metal strips are used along the ridge lines of roofs and around all roof obstacles to prevent the growth of bacteria and algae. These are available from manufacturers in various widths in 50-foot rolls. As rain falls and washes over the metal and down the shingles, the unwanted growth is weakened and eventually dies off.
Toms River roofing contractors FAQ:
How do I clean my roof with trisodium phosphate (TSP)?
The usual formula for a TSP-based cleaning solution is to mix 1 quart of bleach (six percent hypochlorite) with 1 gallon of water and 1/4 cup TSP. Never add ammonia or an ammonia-based cleaner into this solution. Mixing ammonia with bleach produces a poisonous gas. Mix the solution thoroughly, then put it into a pump type of garden sprayer. Spray solution onto the roof and leave on for 15 minutes. Rinse with clean water, and be sure to follow all safety precautions.
