Cleaning your roof is a smart investment to prolong the life of your roof. The black streaks that grow on roofs are called gloeocapsa magma. Gloeocapsa magma are algae spores that have attached to your roof and will cause damage and rot.  

Roof cleaning in Wisconsin is more than just a cleaning service; it is a protective and preventative treatment that ensures your roof is free of pollutants and muck that may harm your home and endanger the health of your family.

Roof Washing — Frequently Asked Questions
Soft wash roof cleaning uses low water pressure with professional cleaning solutions to kill and remove moss, algae, lichen, and black streaks without damaging shingles. High-pressure washing strips granules from asphalt shingles, voids manufacturer warranties, and shortens roof life. Blueline uses only soft wash methods on all residential roofing — it's the approach recommended by the ARMA (Asphalt Roofing Manufacturers Association).
Yes, when done correctly with soft washing. In fact, removing moss, algae, and lichen from asphalt shingles extends roof life — these organisms break down roofing materials over time and accelerate wear. Wisconsin's humid summers and wet springs create ideal conditions for growth. Soft washing kills the growth at root level so it doesn't come back quickly, unlike a simple rinse.
Roof washing in Pewaukee and Waukesha County typically ranges from $300 to $600 for a standard residential roof, depending on roof size, pitch, and the degree of moss or algae growth. We provide free estimates with no obligation — request yours online or call 262-525-8327.
Most roofs in southeast Wisconsin benefit from cleaning every 2 to 3 years depending on tree coverage and roof orientation. North-facing roofs and those under heavy shade accumulate moss and algae fastest. If you can see black streaks or green patches from the ground, it's time. Catching growth early prevents the kind of deep-root lichen damage that requires roof replacement sooner than expected. Pair your roof wash with gutter cleaning in one visit.
