In our area, the most common cause is failed or degraded flashing and sealant around the skylight due to temperature fluctuations, ice dams, and wind-driven rain. Our fix involves a thorough inspection to locate the exact breach, complete removal of the old sealant, installation of new, high-grade flashing, and application of a premium waterproof sealant designed for our local climate to ensure a long-lasting repair.

Yes, when done correctly. We use a specialized soft wash technique for roof moss removal. This method applies a biodegradable cleaning solution that kills the moss at the root, followed by a very low-pressure rinse. This approach is safe for asphalt shingles, prevents granules from being blasted off, and is more effective than high pressure alone, which can force water under shingles and cause leaks.

Roof moss doesn't just stay on the roof. As it grows and spreads, moisture and organic debris can run down onto your siding and trim, leading to mold, mildew, and wood rot that damages paint and underlying materials. Our pressure washing service removes this threat at the source. Following up with a fresh coat of paint from our team seals and protects the siding, creating a comprehensive defense system for your home's exterior.
