Those black streaks and dark stains on your roof are usually algae growth, not simple surface dirt. In Mississippi, humidity, shade, tree cover, and warm weather create ideal conditions for roof algae, mildew, moss, and organic staining to spread across shingles.
Soft Wash Roof Cleaning for Black Streaks and Algae
We clean roofs using a soft washing process instead of high pressure. That means the roof is treated with the proper cleaning solution at low pressure so the algae and organic growth can be broken down safely without forcing water under shingles or stripping protective granules from asphalt roofing.
This is the correct approach for roof cleaning, roof soft washing, black streak removal, and algae stain treatment. We do not treat shingles like concrete, and we do not use aggressive pressure washing on roof surfaces.
ARMA Recommended Roof Cleaning Method
The Asphalt Roofing Manufacturers Association recommends cleaning asphalt roofing with a chemical cleaning solution and low-pressure application, not high-pressure washing. We follow that same soft wash principle when cleaning asphalt shingle roofs.
Using the right method matters. High pressure can remove granules, damage shingles, and create problems that are more expensive than the original staining. Soft washing allows us to treat algae, mildew, moss, and roof discoloration while protecting the roofing material.
Insurance Renewal and Dirty Roof Concerns
If your insurance company has raised concerns about your roof looking dirty, stained, neglected, or discolored, we may be able to help. A professional roof cleaning can improve the appearance of the roof and help show that the staining is algae growth rather than roof failure.
