An Asphalt Shingle Roof Covered In Algae Spores: Things To Know

Posted on: 23 December 2015

Have algae spores caused your asphalt shingle roof to look unappealing because of all of the black streaks on it? You are dealing with more than the problem of your roof looking bad; it is also at risk for deterioration if the algae spores are not removed fast enough. Discover below what you should know about an asphalt shingle roof that is covered in algae spores.

What Kind of Harm Can Algae Spores Cause to Asphalt Shingles?

If you leave the algae spores on your roof for too long, the asphalt shingles will start to deteriorate (if they haven't already). Basically, the spores will consume the limestone that asphalt shingles contain. As the limestone is consumed, your shingles will end up with holes in them. The bad thing about holes in shingles is that they cause the roof deck to be exposed, and this should be prevented at all costs. An exposed roof deck will eventually deteriorate and possibly lead to rainwater dripping on the interior of your house, which will lead to you needing a new roof altogether.

How Should Algae Spores on Asphalt Shingles Be Removed?

The best way for algae spores to be removed from asphalt shingles is via pressure washing equipment. However, it is important for you to hire a roofer to perform the task for you. He or she will be able to do an inspection of the shingles to determine if any of them should be replaced due to deterioration. Leaving the removal of algae spores to a professional can also prevent your shingles from getting damaged from the powerful water of a pressure washing equipment. The roofer will know how to apply just the right amount of water to get rid of algae spores without the shingles coming loose.

What Does it Cost to Get Shingle Damage from Algae Spores Repaired?

A roofer will charge you based on the square footage of asphalt shingles that are in need of being replaced. For instance, you can expect to pay at least $100 or more to get a 10x10 square feet area of asphalt shingles professionally repaired. The overall price that you are charge will also depend on the severity of the algae spores on your roof and the labor involved removing them. If your roof is sloped, it can make the repair more complex for the roofer and affect the price. Contact a roofer so he or she can inspect your roof and quote a price for roof repairs!
