Roof Soft Washing in Chicago’s North Shore
Safe cleaning that removes algae and moss without damaging your shingles.
Roof soft washing removes the algae, moss, and mold that shorten your roof’s lifespan. Those dark streaks on your shingles are Gloeocapsa magma — a type of algae that feeds on limestone filler in asphalt. Left alone, it traps moisture and accelerates wear.
We use low-pressure water with eco-friendly cleaning solutions that kill organic growth at the root. The solution prevents regrowth for months, and the gentle application means no damage to shingles, flashing, or gutters.

Why a Clean Roof Matters
Extend Roof Life
Algae and moss trap moisture against shingles, leading to premature aging and granule loss. Soft washing removes them safely.
Prevent Costly Repairs
Dark streaks and organic growth lead to granule erosion and leaks over time. Removing them now avoids expensive fixes later.
Improve Curb Appeal
A clean roof makes the entire home look newer and better maintained — which matters when it comes to property value.

Frequently Asked Questions
How much does roof soft washing cost?
Roof washing starts at $590. Pricing depends on roof size, pitch, the amount of algae or moss growth, and accessibility. Steeper roofs and multi-story homes require additional safety measures.
Will soft washing void my roof warranty?
Soft washing is the method recommended by most shingle manufacturers, including Owens Corning and GAF. High-pressure washing can void warranties by stripping granules. Our low-pressure approach preserves the shingle surface.
How often should a roof be soft washed in the Chicago area?
Every two to three years is typical for most homes. Roofs shaded by trees or facing north may need treatment more frequently because those conditions promote faster algae and moss regrowth.
Can roof washing be done in cold weather?
The cleaning solution works best when temperatures are above 40 degrees Fahrenheit. In the Chicago area, the season runs roughly from April through November. We schedule around weather conditions to ensure effective treatment.
Is it normal to see results gradually instead of immediately?
The cleaning solution kills algae and moss on contact, but dead organic material may take a few weeks of rain to fully wash away. The roof continues to improve in appearance over the weeks following treatment.
