Those unsightly streaks and stains on your roof don't just mean it's dirty — they could actually mean it's dying. They're caused by an algae called gloeocapsa magma, and the algae spores multiply, feeding on the material your shingles are made of. This degrades your roof's UV protection and overall decreases the lifespan of your roof, which could lead to earlier-than-expected rises in energy bills and roof repairs (something your wallet doesn't want).
It's a good idea to have your roof checked every few years anyway, but GEM offers a 5-year guarantee on all its soft-wash roof cleaning services.
