Roof Washing
Soft-wash roof cleaning that erases black streaks and adds years to your shingles.
Those ugly black streaks running down your roof aren’t dirt — they’re a living algae called Gloeocapsa magma that feeds on asphalt shingles and thrives in Michigan’s humid, shaded conditions. Left alone, it spreads, traps heat, and shortens the life of your roof. Roof washing removes it completely and stops it from coming back.
We clean roofs the right way: a 100% low-pressure soft wash. Power washing a roof blasts the protective granules off your shingles and can void your manufacturer’s warranty. Instead, we apply a manufacturer-approved cleaning solution that kills the algae, moss, and lichen at the root, then gently rinse — no scrubbing, no granule loss, no damage.
The payoff is a roof that looks years younger, sheds heat better, and lasts longer — protecting one of the most expensive components of your home.

Roof Washing — FAQs
What are the black streaks on my roof?
Those streaks are a hardy blue-green algae called Gloeocapsa magma. It feeds on the limestone filler in asphalt shingles and spreads across damp, shaded roofs — extremely common in humid Michigan summers.
Will pressure washing damage my roof?
Yes — high pressure strips the protective granules off asphalt shingles and can void your warranty. We only soft wash, which is the method the Asphalt Roofing Manufacturers Association recommends.
How often should a roof be cleaned?
Most metro Detroit roofs benefit from a soft wash every 2–4 years, depending on tree cover and shade. Catching it early prevents permanent staining and premature shingle aging.
