Roof Cleaning

Remove black streaks and algae from shingle, tile, and metal roofs without high pressure

Those black streaks running down a Florida roof aren't dirt — they're a living algae called Gloeocapsa magma, and they spread. Left alone, the algae digests the limestone in shingles and shortens roof life. We apply a low-pressure soft wash that kills the algae at the root, then a gentle rinse. The roof comes back clean, the algae stops eating your shingles, and the whole house looks newer.

What's included

No high pressure on the roof — soft-wash treatment only (the only method shingle manufacturers approve)
Effective on asphalt shingle, tile, and metal roofs
Kills the algae at the root, so streaks don't reappear in 6 weeks
Gutters and downspouts protected with a pre-treatment rinse
Driveway and surrounding concrete rinsed afterward
Most Lakeland roofs cleaned in 2 to 4 hours

Common questions about roof cleaning

What are the black streaks on my roof?

It's algae — specifically Gloeocapsa magma. It thrives in the Florida humidity and feeds on the limestone filler in asphalt shingles. Left untreated for years, it can shorten a roof's lifespan by 20 to 30 percent. The streaks are a sign the algae is already established.

Will pressure washing the roof void my warranty?

Yes — every major shingle manufacturer (GAF, Owens Corning, CertainTeed) explicitly prohibits pressure washing and voids the warranty if you do. They specifically recommend the low-pressure soft-wash method we use, which is also what ARMA (the Asphalt Roofing Manufacturers Association) endorses.

How long does a roof cleaning last?

A proper soft-wash clean keeps a Lakeland roof streak-free for 3 to 5 years. Roofs under heavy oak cover may see early regrowth and benefit from a 2 to 3 year cycle. We offer a 24-month spot-treatment warranty.

Is roof cleaning safe for the landscaping below?

Yes — we pre-wet plants before any treatment, dilute runoff, and rinse the area after. We've cleaned thousands of roofs over mature landscaping without damage.

What does roof cleaning in Lakeland cost?

Most Lakeland-area roof cleanings fall between $400 and $750 for a single-family home. Two-story, steep-pitch, and tile roofs run higher. Send a photo and the address and we'll quote it same-day.
