That black streaking on your roof is not dirt. It is a type of algae called Gloeocapsa Magma. It feeds on the limestone filler in your shingles and spreads fast in the humidity we get here in Davie County.
Why Pressure Washing Your Roof Makes It Worse
Pressure washing blasts algae off today. But it strips the granules from your shingles at the same time. You end up with a clean roof that fails years early.
Most shingle manufacturers actually void the warranty if pressure washing is used. Soft washing is the method they recommend.
What Soft Washing Does
Soft washing uses low pressure and a biodegradable cleaning solution. The solution kills algae, moss, and mildew at the root. It does not just clean the surface. It stops regrowth.
Your shingles stay intact. Your roof warranty stays valid. Results last four to six times longer than pressure washing.
What a Soft Washed Roof Actually Looks Like
Here is the difference soft washing makes on a typical Mocksville composition shingle roof:
Before
After
Same roof. No pressure washing. The algae is gone because the organism was killed, not just blasted off the surface.
What We See on Roofs Around Mocksville
Most homes in Mocksville, Cooleemee, and Advance have composition shingle roofs. They hold moisture, which means algae and moss show up fast.
Moss buildup is common near tree lines and on north-facing roof pitches. Left alone, it holds water against the shingles and speeds up rot underneath.

FAQ: Soft Wash Roof Cleaning
How long does soft wash roof cleaning last?
Soft washing typically keeps your roof clean for three to five years. Pressure washing may look clean for a few months before algae comes back. The difference is that soft washing kills the organism, not just the surface stain.
Is soft washing safe for all roof types?
Yes. Soft washing works on composition shingles, metal roofs, tile, and cedar shake. We adjust the solution and pressure for each material. Pressure washing is not safe for most residential roofs.
Will the cleaning chemicals hurt my plants or gutters?
We wet down plants and shrubs before and after the cleaning. The biodegradable solution we use breaks down quickly. We also flush gutters and downspouts after every job.
