Those dark streaks on your roof? That’s algae eating your shingles.
A low-pressure power wash kills the growth and brings your roof back to its original color — without stripping granules or voiding your warranty. Nazareth, Easton, Bethlehem, Allentown, and nearby towns.

Is pressure washing a roof safe?
No. High pressure strips the granules off asphalt shingles and shortens the life of the roof. Those black streaks are algae, and they come off with a low-pressure power wash treatment that kills the growth and rinses clean. The roof is never walked or blasted more than it needs to be.
Those black streaks are alive
The dark streaking on Pennsylvania roofs is an algae called gloeocapsa magma. It feeds on the limestone filler in asphalt shingles, spreads from roof to roof on the wind, and slowly shortens the life of the shingle underneath it. Insurers and home inspectors notice it too.
The fix is a low-pressure treatment that kills the growth at the root — not pressure, which strips granules and voids warranties. Done right, a treated roof stays clean for years.

Why the streaks come back
Those streaks are living algae feeding on the limestone filler in shingles. Rinsing alone just moves it. Treating it kills the growth so the roof stays clean much longer.
Pairs naturally with a house wash
Roof runoff lands on your siding. Cleaning both in one visit is faster, cheaper, and looks far better than doing one and not the other.

Where we do this work
Bundles
Bundle this with other work and save.
One setup, one water source, one visit. Combining surfaces is almost always cheaper than booking the same work twice — and it is the single easiest way to lower your total.
Curb Appeal
Everything the street sees, cleaned in one visit.
- House and power wash
- Driveway surface cleaning
- Front walk and steps
- Optional: porch and railings
Outdoor Living
The part of the property you actually use.
- Deck or patio wash
- Paver or pool deck cleaning
- Fence washing
- Optional: outdoor kitchen and grill area
Seasonal Protection
Get ahead of the leaves and the freeze.
- Full gutter clearing and flush
- Dryer vent cleaning
- Exterior rinse-down
- Optional: concrete before frost
We run three to five jobs a week, so the fall weeks — gutters, concrete, and decks before the freeze — fill before the season starts. Getting on the schedule early is the difference between a date you picked and whatever is left.
FAQ
Roof cleaning — common questions
Will roof cleaning void my shingle warranty?
Low-pressure power washing is the method shingle manufacturers generally accept, unlike high-pressure washing. We can walk through the approach before we start.
How long do results last?
Because the treatment kills the algae rather than just rinsing it, most roofs stay clear for years rather than months. Heavy shade shortens that window.
Do you clean the gutters too?
Gutter faces are usually cleaned as part of the visit, and full gutter clearing can be added.
