Roof Cleaning in Worcester, MA
Those black streaks are algae eating your shingles. We remove them safely with low-pressure soft washing that protects your roof's warranty and granules.
Black Streak & Moss Removal
The dark streaks running down New England roofs are a blue-green algae called Gloeocapsa magma, and the fuzzy green patches are moss holding moisture against your shingles. Left alone, both shorten the life of your roof. Our roof cleaning removes them with a soft-wash treatment that kills the growth without ever putting a pressure washer to your shingles.
High-pressure roof cleaning blasts the protective granules off asphalt shingles and can void your manufacturer's warranty. Our low-pressure, solution-based method is the approach recommended by shingle manufacturers and the ARMA — safe for asphalt, cedar and metal roofs across Worcester County.
Why roofs streak and grow moss in New England
Our humid summers and shaded, tree-lined lots are ideal for algae and moss. North-facing roof slopes stay damp the longest and streak first. Once algae is established it spreads across the whole roof, and moss works its roots under the shingle edges, lifting them and letting water in.
That's why treating it early is worth it: roof cleaning while the growth is young is far cheaper than replacing shingles that moss has pried loose. It also keeps your home looking cared-for, which matters a lot if you're selling or refinancing.
Our low-pressure roof cleaning treatment
We apply a professional soft-wash solution that kills algae, moss and lichen, then let it do the work. The growth releases and continues to wash away with the rain over the following weeks. There's no pounding, no aggressive scrubbing, and no high-pressure water anywhere near your granules, flashing or vents — just a safe, thorough roof cleaning that protects the roof you paid for.
Protecting your warranty and your investment
A roof is one of the most expensive parts of your home, and the wrong cleaning can cost you the warranty. We follow the manufacturer-approved soft-wash method, work safely from ladders and the ground wherever possible, and never walk a roof more than necessary. You get the black streaks and moss gone without any of the risk that comes from a high-pressure roof cleaning.
