The black streaking you see on your roof is an algae called gloeocapsa magma. It is very aggressive and spreads very quickly. Unfortunately, there is an unlimited food source on your roof that keeps this algae thriving unless action is taken to kill it.
This algae ruins your roof and also has a terrible appearance. It is actually eating the limestone filler in your shingles. This can cause the granules in your shingles to loosen and fall off. This moss may grow so heavily that you see a small plant or growth on top of your roof. You may have even seen a dark mud looking substance at the downspouts of your gutters. That is not mud, it is actually shingle grit that has eroded from your roof.
Let Parks Roof Cleaning by Parks House Washing conduct a free roof cleaning demonstration for you.
Our process is simple and is harmless to your roof. Our process does not require heavy power washing which can damage your roof.
The roof cleaning process includes:
- Initial administration of a proprietary blended cleaning solution in which we allow to soak for 1-2 hours
- We will then apply a second application on the roof as necessary for a 24 hour soak
This process may take up to 24-72 hours. We will make several visits to your residence and reapply solution as necessary until ALL algae is removed.
We guarantee 100% satisfaction and a longer roof life!
