Moss is common here due to our humidity and shaded areas. We recommend professional removal, as scraping it off yourself can damage shingles. After cleaning, we often apply a zinc or copper treatment strip near the roof's peak. This creates a solution that washes down with rain, preventing moss from returning for years and protecting your roof's lifespan.

Flashing separation around chimneys, vents, and valleys is frequent in York because of our temperature swings, which cause materials to expand and contract. A temporary sealant often fails. For a permanent fix, our technicians remove the old flashing, properly prepare the surface, and install new, high-quality flashing with secure fastening and professional sealants designed to withstand our local weather cycles.

Act immediately. Even a small leak from a compromised flashing or under moss can lead to significant water damage, mold, or rot inside your attic and walls, especially with Pennsylvania's rainfall. We offer prompt inspections to locate the source—often where you see a stain isn't where the water enters—and provide a clear repair plan to stop the damage and protect your home's value.
