Roof stains can seriously detract from the favorable appearance of a property, whether it be a business attempting to draw customers, or a homeowner simply dissatisfied that all the time, effort and resources invested in their property are being undermined by ugly black streaks on their roofs.
We hear about it all the time from our customers:
"I don't know where these stains are coming from!"
"I never had this problem until a few months ago!"
"I tried doing it myself but the stains were back in three months!"
"I didn't know there was anything I could do about them...then a neighbor told me about you."

There are various types of infestations that can occur on a roof, and we have seen them all. Algae and other growths are not particular where they grow, except they flourish on the northern side of a building, which is generally away from the sun and therefore more moist.
Shingles are shingles, and they all seem prone to this scourge, so we can help with commercial establishments as well as private homes.
Question:
How does algae get up on my roof in the first place?
Answer:
Algae spores can blow onto your roof. Once there, and the environment is moist, they are on their way!
The recent and ongoing onslaught of algae and other growths on roof shingles is presenting real problems for conscientious business and home owners.
Options appear to be limited:
Endure the extraordinary expense of shingle replacement, only to have the new shingles develop the same problems;
Ignore the stains, which will continue to darken and possibly ruin your shingles;
Attempt to remove the stains yourself, which is dangerous both to you and your shingles...only to have the stains reappear.
Instead, why not call the professionals. We do this all the time, and are quite good at it!
