In our area, skylight leaks are often caused by failed or degraded flashing seals due to thermal expansion and contraction from temperature swings. We start by inspecting the flashing and sealant for cracks or gaps. Our repair involves removing the old sealant, cleaning the area thoroughly, and applying new, high-grade, UV-resistant sealant designed for our climate. If the flashing is damaged, we'll replace it to ensure a watertight seal that lasts.

Signs of underlayment damage inside your home include water stains on ceilings or walls, especially after wind-driven rain common in the Gorge. From the outside, you might see curled or missing shingles. Addressing it quickly is crucial because damaged underlayment compromises your roof's primary water barrier, leading to wood rot, mold, and major structural issues. We perform a detailed inspection, remove affected shingles, replace the compromised underlayment with a high-quality synthetic underlayment for better durability, and re-shingle the area securely.

Absolutely. As a full-service general contractor, we efficiently manage multiple projects. For example, we can schedule your urgent roof leak repair to stop water intrusion immediately, then seamlessly transition to installing a new cedar or vinyl fence to enhance your property's security and curb appeal. This coordinated approach saves you time and the hassle of hiring separate specialists, ensuring all work meets our consistent standards of quality.
