Those black streaks are alive — and they're eating your shingles
Non-pressure removal of the black streaks that shorten shingle life.
About our roof cleaning service
The dark streaks running down asphalt roofs across the River Valley are a cyanobacteria called Gloeocapsa magma. It feeds on the limestone filler in shingles and holds moisture against the roof surface, which is why a streaked roof isn't just an appearance problem.
Roof cleaning is done without pressure. Pressure lifts granules off shingles and voids warranties. Instead, a cleaning solution is applied, allowed to work, and rinsed gently — the growth dies and the roof returns to an even color.
Who this is for
- Homes with dark streaks or patches on asphalt shingles
- Metal roofs with algae, oxidation film, or organic staining
- Owners quoted for a roof replacement who may only need a cleaning
- Sellers whose roof condition is being questioned by buyers
What our roof cleaning service covers
Every job follows the same sequence so nothing gets skipped.
Roof condition check
We look at the shingle or panel condition before proposing anything.
Non-pressure application
Solution is applied gently — no granule loss, no lifted shingles.
Full dwell and kill
The growth is killed rather than scrubbed off, so it stays gone longer.
Gutter and downspout flush
What we rinse off the roof gets flushed through so it doesn't sit in the gutters.
Landscape and siding protection
Everything below the roofline is pre-wet, protected, and rinsed.
Ground-level review
We walk the perimeter with you to confirm coverage on every slope.
Why roof cleaning is worth doing
Extends roof life
Removing organic growth stops it from degrading shingle material and holding moisture.
Avoids premature replacement
Roofs are often replaced for appearance when the shingles still have years left.
Keeps the roof warranty intact
Non-pressure cleaning is the method shingle manufacturers accept.

It should never be done. High pressure strips protective granules from asphalt shingles and can void the manufacturer warranty. We use a non-pressure method only.
Eventually — the spores are airborne. How fast depends on shade, humidity, and nearby tree cover.
Yes, with the right process. Everything below the roofline is pre-wet and rinsed afterward.
Yes. Metal roofing is cleaned with a method matched to the panel finish.
Often booked together
