Roof Washing in Arlington, TX — Safe Low-Pressure Soft Wash Cleaning
What Are Those Black Streaks on Your Roof?
If you’ve noticed dark streaks or staining running down your roof shingles, you’re not imagining it — and it’s not just dirt. Those black streaks are caused by a type of algae called Gloeocapsa Magma, which thrives in warm, humid climates like North Texas. This algae feeds on the limestone filler in asphalt shingles, slowly breaking down the material and shortening your roof’s lifespan.
Left untreated, it spreads across your entire roof, attracts moss and lichen, and can cut years off the life of your shingles — meaning a costly early replacement. Fortunately, professional roof soft washing removes it completely.
Why High-Pressure Washing Will Damage Your Roof
Many homeowners — or inexperienced contractors — make the mistake of using high-pressure water to clean a roof. This is a serious problem for two reasons:
- It physically damages your shingles. High-pressure water strips the protective granules from asphalt shingles. Those granules are what protect your roof from UV rays and weather. Once they’re gone, the shingle deteriorates quickly.
- It voids your warranty. Most asphalt shingle manufacturers — including Owens Corning, GAF, and CertainTeed — specify that high-pressure washing voids the product warranty. A low-pressure soft wash is the only cleaning method they approve.
Stegmeier Pressure Washing uses exclusively soft wash methods on all roof cleaning jobs. We never apply high pressure to shingle surfaces.
How Our Roof Soft Washing Works
Our Arlington roof washing process is safe, effective, and approved by shingle manufacturers:
- Property protection — we cover any sensitive landscaping or equipment below the roofline before we begin
- Low-pressure solution application — we apply a contractor-grade biocide cleaning solution using a low-pressure soft wash system
- Dwell time — the solution penetrates and kills algae, moss, mold, and lichen at the cellular level
- Gentle rinse — we rinse the roof with low-pressure water to flush away dead growth and residue
- Inspection — we do a final check to confirm all staining is cleared and the job is complete

Roof Washing FAQs
A: Not with our method. We use 100% soft wash — low pressure with cleaning solutions. High-pressure washing damages shingles; soft washing does not.
A: Most Arlington homeowners benefit from roof cleaning every 2–3 years. Homes with significant tree canopy overhead may need it more frequently due to faster algae and moss growth in shaded areas.
A: We strongly advise against it. Aside from the warranty and damage risks, walking on a wet roof is extremely dangerous, and rented pressure washers rarely deliver the right combination of pressure and cleaning chemistry to fully kill the algae — meaning it comes back faster.
A: We take careful precautions to protect all plant life near your home, including pre-wetting and post-rinsing all flower beds and grass near the roofline. Our solutions are biodegradable and safe once neutralized.
