Those black streaks are algae eating your shingles. We remove them the manufacturer-approved way.
Black streaks running down a roof aren't stains, they're a living algae that feeds on shingle material. Moss does even more damage, prying shingles up as it grows. On our damp, tree-lined North Shore lots, both love it here.
A roof should never meet a pressure washer. Blasting shingles strips the granules that protect them and can knock years off the roof. We use the soft wash method: the treatment does the killing, and rain does most of the rinsing. It's the approach shingle manufacturers approve.
A roof is the most expensive surface on your house. Washing it costs a few hundred dollars; replacing it early costs tens of thousands. Regular treatment stops the freeloaders before they do structural damage, and the house looks sharper the same day.
Roof washing is priced by home size and roof condition. Request your quote online and we'll have your number back fast.
Yes, the way we do it. No pressure ever touches the roof. The cleaning solution kills the algae and moss, and it rinses away gently.
Algae streaks fade fast, often same-week. Thick moss dies immediately but can take a few weeks of weather to fully let go and wash off.
Every two to four years for most homes here, sooner if your lot is heavily shaded. Once the growth is dead, staying ahead of it is cheap.
Yes, and most people do. One trip, one crew, everything clean at once. Put your home on a biannual plan and $50 comes off every cleaning, or quarterly for $100 off every cleaning.
