Fungus & Debris in Troy, OH
Algae, moss, and buildup cleared and treated so the roof stays healthy.
Black streaking and moss hold moisture against the mat and shorten shingle life. We clear and treat without pressure-washing away your granules, and add algae-resistant components on replacements.
The black streaking on north-facing slopes is airborne algae, and moss is worse: it holds water against the mat and lifts shingle edges as it grows. Both shorten the life of a roof that is otherwise fine.
The wrong fix does more damage than the growth. A pressure washer strips the granules that are the shingle's actual weather surface and can take years off a roof in an afternoon. We clear and treat without doing that, and on replacements we specify algae-resistant components so the problem does not simply grow back.
- Moss, algae and debris cleared without pressure-washing
- Treatment that does not strip the granule surface
- Valleys and gutters cleared so water actually leaves the roof
- Algae-resistant GAF components specified on replacements
Fungus & Debris, answered
Will you pressure-wash my roof?
No. Pressure-washing strips the granules that are the shingle's weather surface and can take years off the roof in a single afternoon. We clear and treat without it.
Does the black streaking actually matter?
It is airborne algae. Mostly cosmetic on its own, but it holds moisture against the mat, and moss, which often comes with it, lifts shingle edges as it grows.
Can it be prevented?
On a replacement, largely yes. Algae-resistant GAF components are made for exactly this and carry their own StainGuard warranty terms.
