Our Roof Cleaning Process

01

Roof Inspection

We inspect your roof type, condition, and specific growth patterns to determine the safest and most effective cleaning approach.

02

Plant and Surface Protection

Surrounding landscaping, gutters, and exterior surfaces are rinsed and protected before treatment begins.

03

Soft Wash Application

We apply an EPA-approved biodegradable cleaning solution that kills algae, moss, lichen, and mold at the root — without high-pressure that can crack or displace tiles and shingles.

04

Low-Pressure Rinse

Surfaces are gently rinsed. Results continue improving over 1–2 weeks as dead organisms naturally wash away with rain.

Roof Cleaning FAQ for Philadelphia Homeowners

How often should Philadelphia homeowners get roof cleaning?
Given Philadelphia's cold winters with freeze-thaw cycles damaging mortar, most homeowners benefit from roof cleaning at least once a year. Winter ice dam and mortar damage often makes spring or fall the optimal time to schedule service.
What home types in Philadelphia most need roof cleaning?
Red brick rowhouses (very common) and Twin and semi-detached homes are the most common home types in Philadelphia and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
What are the black streaks on my roof?
Black streaks are caused by Gloeocapsa Magma, a type of algae that feeds on the limestone filler in asphalt shingles. Left untreated, it accelerates granule loss and shingle degradation.
Is soft washing safe for my roof?
Yes. Soft washing uses low pressure and specially formulated cleaning solutions — the same method recommended by the Asphalt Roofing Manufacturers Association (ARMA). High-pressure washing can void warranties and damage shingles.
How long does roof cleaning last?
Results typically last 2–4 years depending on your climate and tree cover. Humid or shaded roofs may need cleaning more frequently.
Will roof cleaning damage my gutters?
No. We use low-pressure techniques and protect your gutters and downspouts throughout the process. Cleaning your roof often coincides with a gutter cleaning service.
Can roof cleaning prevent roof replacement?
Yes — regular cleaning removes organisms that degrade roofing materials over time. Homeowners who maintain clean roofs typically extend their roof's functional lifespan significantly.
