In Grants Pass, roof valley leaks are often caused by debris accumulation (like pine needles) blocking water flow, or by worn or improperly installed flashing. We start by clearing all debris, then inspect the valley metal and underlying underlayment. Repair typically involves sealing minor issues or replacing damaged flashing and shingles to restore a watertight channel, ensuring water sheds properly off your roof.

Chimney flashing leaks that recur are usually a sign of a systemic issue, such as step flashing that wasn't integrated correctly with the roof shingles, or corrosion of the metal itself. In Grants Pass, temperature swings can exacerbate these problems. Our expert repair involves a complete assessment, often requiring the removal of surrounding shingles to properly re-install or replace the step flashing and counter-flashing, creating a durable, sealed barrier.

While repairs are ideal for isolated damage, a full replacement becomes necessary when leaks are widespread, the roof is near or past its typical lifespan (often 20-25 years in our area), or when underlying decking is compromised. We'll provide a honest assessment; if frequent repairs in valleys or around chimneys point to general roof failure, investing in a new, modern roof with enhanced flashing details is often the most cost-effective long-term solution for your home.
