Roof Washing That Removes Black Streaks for Good
Those black streaks are living algae eating your shingles. Our no-pressure soft wash kills it at the source and restores your roof's appearance.
The problem
Black streaks, moss, and lichen aren't just ugly — they shorten the life of your roof and can void some warranties.
The Rally result
A clean, uniform roof that adds years of life and instantly lifts the look of your entire home.

Jason did an incredible job power washing our house — it looks brand new again! He was super easy to work with, didn't make things overly complicated, and got us a great rate within our budget. Will definitely recommend to friends, family and neighbors!

House washing
Our church building hadn't been washed in years and our gutters were plugged. In 8 hours all the black and green were gone — the gutters were black and now they're white again. They did a great job and never quit until the job was done.

Church building
Jason did a phenomenal job power washing our entire driveway, sidewalk, and the pergola at the back of our house. The areas look brand new.

Typically $0.20–$0.55 per square foot of roof area — around $350–$600 for an average single-story home and $600–$900 for two-story or steep roofs. Heavy moss or lichen adds treatment time. Free assessments, exact quotes in writing.
A living algae called Gloeocapsa magma that feeds on the limestone in your shingles. It's not just cosmetic — left alone it shortens roof life and can void some shingle warranties. Our soft wash treatment kills it at the source.
Never — high pressure strips shingle granules and causes the exact damage you're trying to avoid. We use the manufacturer-approved no-pressure soft wash method: treatment does the work, not force.
No — and that's good news for your wallet. We're the roofing care side of the trade: we clean and protect the roof you have so it looks new and lasts years longer, instead of selling you a $15,000 replacement.
Most roofs stay streak-free for 2–4 years after a professional soft wash, depending on shade and tree cover. North-facing and heavily shaded roofs regrow algae fastest.
