Roof washing for dark streaks and buildup.

Those dark streaks you notice from the street are often caused by algae, especially in warm, humid weather. Roof cleaning can help address that buildup without relying on the heavy water pressure used for concrete.

Roof washing needs a different approach from driveway cleaning. A soft-wash method uses low pressure and a treatment selected for the roof surface. We’ll review the material, staining and access before confirming what’s appropriate for your home, then recommend the safest next step for your roof.

Questions

A few things people ask.

Is this high-pressure roof cleaning?

No. For residential roofs, the goal is a low-pressure soft-wash approach appropriate to the roofing material—not blasting shingles like a driveway.

What causes the black streaks?

Dark streaks are often algae, though rust, shade-related growth and other staining can look similar. The first step is identifying what’s there.

Will every roof be suitable for cleaning?

No single method fits every roof. Material, age, condition and access need to be considered before confirming service.
