Why roofs streak, and how we clean them

In a climate as warm and humid as Seminole County's, algae grows on the shady parts of a roof and spreads a little further every year. On asphalt shingles it shows as black stripes running toward the gutters. On barrel tile, the terracotta turns dark and patchy. Either way, it holds moisture against the roof.

High pressure is the wrong tool for the job. It can blast the granules off shingles and crack or shift tiles. Roofs get soft washing instead: a cleaning solution breaks down the growth, and a low-pressure rinse takes it away.

Tsunami Services has photos of both kinds. One is a barrel tile roof beside a screened pool, dark before and clean terracotta after. The other is a shingle roof that went from black-streaked to an even gray.

Roof Cleaning, Step by Step

Three steps to a cleaner roof

You don't need to climb up there. A photo from the ground is enough to start.

  • Send a roof photo

    Tell us whether it's shingle or tile, how many stories the house is, and where the streaks are worst.

  • Get your estimate

    We'll quote the roof and anything else you want added, like gutters or solar panels.

  • Soft wash and rinse

    The solution goes on, the growth breaks down, and a gentle rinse clears it. A neutralizer protects the plants below.

Roof Cleaning Questions

What to know before your roof gets cleaned

  • A soft wash is used precisely because it doesn't. The low-pressure rinse leaves shingle granules in place and doesn't knock tiles loose. If you know of cracked tiles or lifting shingles, mention them so we can work around them.

  • Black streaks are a cleaning problem, not a sign the roof is worn out. Cleaning won't fix leaks, missing shingles or broken tiles, though. If you're seeing water inside the house, call a roofer first.

  • That depends on shade and trees. A roof under live oaks streaks again sooner than one in full sun, and the growth comes back gradually rather than all at once. Ask about a yearly plan if you want it kept up.

  • Yes. Gutter and fascia cleaning and solar panel cleaning are both on our list, and booking several services together brings the total down. Add them to your request.
