Residential Roofing
Many homeowners don't know that the unsightly black or brown stains they see on their roofs may be due to blue-green algae. They tend to think that the roof stain is simply dirt or how shingles age and that there's little that can be done to prevent it. But when made aware of the problem, our survey* found that many homeowners would invest in products that help protect against it, which will help you expand your offerings.
