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.
Can I Clean My Roof?
Yes, you can clean your roof, but some methods of cleaning can cause unnecessary wear to the shingles. Many of today's higher quality shingles have an algae-resistant barrier built-in. This barrier helps protect the roof from the unsightly streaks and maintenance hassles caused by algae. CertainTeed produces an asphalt shingle with an algae-resistant Streak-Fighter feature in the shingle. CertainTeed claims that specific raw material in the shingle protects it from the streaking and discoloration commonly caused by algae.
Final Thoughts
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.
