Roof Cleaning in Mountain Top, PA
Safe, no-pressure soft washing that eliminates black streaks and algae — extending your roof's life without risking shingle damage. The method recommended by shingle manufacturers like GAF and CertainTeed.
Those Black Streaks Are Not Just Ugly
If you have noticed dark streaks running down your roof, you are looking at Gloeocapsa magma — a blue-green algae that feeds on the limestone filler in asphalt shingles. It is extremely common in Mountain Top and throughout Luzerne County, especially on north-facing and shaded roof slopes.
Left untreated, this algae retains moisture against your shingles, accelerates granule loss, and shortens your roof's lifespan by years. Many homeowners assume they need a new roof when all they really need is a professional cleaning.
ARMA-Recommended Soft Wash Cleaning
Pressure Pros Power Washing uses the cleaning method recommended by the Asphalt Roofing Manufacturers Association (ARMA): a no-pressure soft wash that relies on specialized cleaning solutions — not brute force — to eliminate algae, moss, and lichen from your roof.
Our process kills the algae at the cellular level and rinses it away gently, preserving your shingles' protective granules. The result is a roof that looks years younger and is protected from the premature deterioration that unchecked algae causes. We clean asphalt shingles, tile roofs, metal roofs, and slate — adjusting our approach for each material.

Every roof cleaning from Pressure Pros is a thorough treatment — not a quick rinse. Here is what you get.

Gloeocapsa magma algae is killed at the root. Black streaks disappear and stay gone far longer than with surface-level rinsing.

Our Roof Cleaning Process
A careful, no-pressure approach that protects your shingles while delivering dramatic results you can see from the street.
Roof Assessment
We inspect your roof from the ground and, if safe, from the roofline to identify the type and severity of growth, the roofing material, and any areas of concern.
Protect & Prep
All landscaping, gutters, and surrounding surfaces are pre-soaked and protected. We cover any delicate plants directly below the roofline.
Soft Wash Application
Our cleaning solution is applied at low pressure from the roofline down, allowing it to flow across the shingles and penetrate algae, moss, and lichen at the root level.
Rinse & Final Check
The roof is gently rinsed, all surrounding areas are washed down, and we do a final walkthrough to ensure every section is clean and your property is spotless.

Roof Cleaning FAQ
The black streaks are caused by Gloeocapsa magma, a blue-green algae that feeds on the limestone filler in asphalt shingles. It thrives in warm, humid conditions — exactly what Mountain Top summers provide. The streaks worsen every year and, left untreated, the algae retains moisture against your shingles and accelerates deterioration.
Absolutely. Soft washing is the method recommended by the Asphalt Roofing Manufacturers Association (ARMA). It uses no high pressure — just a carefully formulated cleaning solution applied at low volume, followed by a gentle rinse. It will not dislodge protective granules or lift shingle edges the way pressure washing can.
Most roofs in the Mountain Top area benefit from professional cleaning every 2 to 4 years. Homes with significant tree coverage or north-facing roof slopes may see algae return sooner. Once you notice dark streaks forming, it is a good time to schedule a cleaning before the growth spreads further.
No. Soft washing will not void your shingle warranty. In fact, most manufacturers explicitly recommend it as the proper cleaning method. High-pressure washing is what can void warranties because it physically damages shingles. Our low-pressure approach follows manufacturer guidelines and keeps your coverage intact.
Pricing depends on the size and pitch of your roof and the severity of the algae or moss growth. Whatever a clean costs, it's a small fraction of premature roof replacement — and a properly cleaned roof can extend shingle lifespan by years.
