Owner’s Roofing | Roofing Services in Bothell, WA 98012

In Bothell, shingle curling is often caused by moisture absorption from our frequent rain and the subsequent expansion and contraction during temperature changes. This compromises the roof's ability to shed water. The fix depends on the extent. For minor, isolated curling, we can often secure or replace individual shingles. However, widespread curling usually indicates an aging roof system or underlying ventilation issues, and a roof replacement with modern, durable shingles is the most reliable, long-term solution to prevent leaks.

Flashing—the metal strips around chimneys, vents, and valleys—fails in Bothell primarily due to corrosion from constant moisture and improper installation. A small flashing failure is a major leak risk. Our repair involves a careful inspection to locate all compromised areas. We then remove the old flashing, prepare the surface, and install new, high-grade metal flashing sealed with professional-grade waterproofing compounds. Proper installation is key to ensuring it directs water away from critical roof junctions for years to come.

Stay proactive with a visual check from the ground after storms. Look for shingles that appear wavy, lifted at the edges, or have lost granules (which look like dark sand in your gutters). For flashing, watch for rust stains, visible gaps, or a bent/misaligned appearance around roof protrusions. Inside your attic, check for daylight peeking through the roof boards or any signs of water stains or moisture. If you see any of these signs, it's time for a professional inspection to address the issue before it leads to interior water damage.
