Keep The Roof Of Your Coastal House Clean

Green and black algae are not only ugly to look at, but it also is a threat to the roof shingles of your house. As algae feeds and spreads it deteriorates the shingle granules reducing the effectiveness of the shingle. Coastal houses, more so than inland homes, are very vulnerable to roof damage due to salt air and wind off the ocean.

Fungus On Roof

Commonly called fungus, algae create unsightly dark brown, green or black streaking on shingles. Sometimes these streaks are mistaken for soot, dirt, moss or tree droppings. While regions with sustained humidity and moisture tend to be most at risk, people who live in all parts of the nation with roofs made from all sorts of materials are susceptible to moss and algae accumulation. In fact, all algae need to survive and thrive are air, water and a food source.

Cleaning Verses Replacement

Methods of cleaning can cause unneeded wear and tear to your shingles. Fortunately, some of the latest shingles come in an algae-resistant version, alleviating unsightly streak and maintenance hassles. For example, many of CertainTeed’s asphalt shingles are available with the algae-resistant Streak-Fighter feature. The company indicates that a specific raw material protects its Streak-Fighter shingles from the streaking and discoloration of airborne algae. Look for it on the company’s wood-shake and slate-style shingles.

Final Remarks

Take a look at your roof. If you start seeing streaks develop, you should either purchase the products to clean your roof or hire someone to do it for you. If your shingles are worn and you are considering installing a new roof, consider using a high quality shingle that has an algae resistant barrier built in.
