Ask Your Auburn Hills Roofing Contractor: How Do I Keep Algae Off My Roof?

As the premier Auburn Hills roofing contractor, Sherriff-Goslin is often homeowners’ first stop when they have questions about their roofs. One of the most common questions concerns a silent headache that is slowly eating away at the roofs of homes in countless US neighborhoods: algae. Costly and time consuming to get rid of, algae is often the result of living in a humid climate and – unfortunately – neglecting to take the steps necessary to prevent its growth.

In the Midwestern climate – with rainy springs and humid summers – algae multiply easily. They attach to asphalt shingle roofs and spread rapidly once they’re airborne. As they grow, they cause the roof to appear stained or streaked, occasionally being mistaken for dirt. Blamed for premature wear, algae’s main effect is to make your roof look neglected – and more damaged – than it actually is. The result, of course, is additional labor keeping the roof looking “fresh.”

There are two primary ways to deal with algae infestation on a roof: regular cleaning and roof replacement. Regular cleaning can be done by applying a bleach and water mixture to the roof, which should rinse away the existing algae and keep the roof clean for a few months. Unfortunately, pressurized cleaning – especially repeatedly – can damage your roof, weakening the asphalt shingles and shortening its overall lifespan.

The other way to deal with algae is a roof replacement. Sherriff-Goslin, a leading Auburn Hills roofing contractor, has been replacing roofs in Michigan for over 100 years.
