Nelson and Nelson Roofing | Roofing Services in Durham, NC 27707

Durham's heavy rainfall often overwhelms the valleys—the critical intersections where two roof slopes meet—leading to leaks if the flashing is worn or improperly installed. We fix this by first removing old, compromised materials, then installing new, corrosion-resistant metal flashing sealed with premium waterproofing compounds. This ensures water is properly channeled away from your roof's most vulnerable point, providing a durable solution tailored to our local climate.

Skylight leaks here are typically due to failed sealant from UV exposure and thermal expansion, or improper flashing installation that can't handle our temperature swings. Our repair process involves a thorough inspection to identify the exact failure point. We then carefully remove the old sealant, replace it with a flexible, weather-resistant urethane sealant, and if needed, re-flash the entire unit to create a watertight barrier that will last for years.

The location of interior water stains often gives it away. Skylight leaks usually show as dampness or staining directly around the skylight well or on the ceiling below it. Valley leaks, however, often manifest as water stains running down interior walls or appearing on ceilings farther from the roof's edge, following the path of the internal valley. If you're unsure, we offer free, no-obligation leak inspections to accurately diagnose the source and recommend the right repair for your Durham home.
