Safe & Effective Soft Wash Roof Cleaning in Wilmington, DE
Remove ugly black streaks and damaging moss with our manufacturer-approved cleaning process.
Don't Replace Your Roof; Clean it!
Are those dark, vertical streaks ruining your home’s curb appeal? Those marks aren’t just dirt; they are a hardy form of algae called Gloeocapsa Magma that thrives in the Delaware Valley’s humidity. At ASA ProWash, we specialize in professional roof cleaning that instantly removes these unsightly stains, making your roof look brand new without the cost of replacement.
We exclusively use a Soft Wash method, which is the only cleaning process recommended by the Asphalt Roofing Manufacturers Association (ARMA). Instead of damaging high pressure, we apply specialized, biodegradable detergents that kill algae, moss, and lichen at the root. This ensures a deep clean that is 100% safe for your shingles and surrounding landscaping in Wilmington, Newark, and Hockessin.
A clean roof does more than just look good—it reflects heat more efficiently. When your roof is covered in dark algae, it absorbs excess heat, forcing your AC to work harder during hot Delaware summers. Our roof cleaning service helps regulate your home’s temperature, potentially lowering your energy bills while giving you the best-looking house on the block.
Extending the Life of Your Roof Throughout the Delaware Valley
Your roof is one of the most expensive components of your home, and neglecting it can lead to premature failure. In communities like Greenville and Pike Creek, moss and lichen are common threats. These organisms don’t just sit on the surface; they root into your shingles, causing them to lift, crack, and lose their protective granules.
By choosing ASA ProWash, you are investing in preventative maintenance that can add years to your roof’s lifespan. Our soft wash treatment doesn’t just wash away the green; it sanitizes the surface to prevent rapid regrowth. It is a fraction of the cost of a new roof and a smart way for New Castle County homeowners to avoid the massive expense of an early replacement.
Safety is our top priority. Roof cleaning is a dangerous DIY task that involves heights and slippery surfaces. Our crew is fully insured and trained in modern safety protocols, allowing you to stay safely on the ground while we handle the grime. We treat your home with the utmost respect, ensuring your gutters and plants are protected throughout the entire process.

Frequently Asked Questions
Will pressure washing damage my shingles?
Yes, high pressure will strip the granules off shingles and void your warranty. That is why we use Soft Washing, a low-pressure chemical treatment that is safe and manufacturer-approved.
What are the black streaks on my roof?
Those are algae called Gloeocapsa Magma. They feed on the limestone filler in your shingles and will eventually cause permanent damage if not treated.
How long does the cleaning last?
Our soft wash treatment typically keeps roofs clean for 3 to 5 years, depending on the amount of shade and tree cover around your home.
Is your roof cleaning solution safe for my plants?
Yes. We pre-wet all landscaping and use a “rinse-as-we-go” method to ensure your plants and grass remain healthy and protected.
Are you insured and trained?
Yes. ASA ProWash is fully insured and our crew is professionally trained in the latest exterior cleaning methods. We take safety and professionalism seriously, giving you peace of mind while we are on your property.
How long does the process take?
Most residential roofs can be completed in 2 to 5 hours, depending on the size and the severity of the organic growth. You’ll enjoy same day results!
Will the moss fall off immediately?
The algae (black streaks) disappear instantly. Heavy moss will die immediately but may take a few rain cycles to naturally detach from the shingles without causing damage.
