Allied Roofing | Roofing Services in Renton, WA 98056

Renton's frequent wind and rain can gradually break down the sealant and fasteners on ridge caps, which are the peak of your roof. Allied Roofing fixes this by carefully removing the damaged cap, inspecting the underlying decking for moisture, and installing a new, properly sealed ridge vent or cap with high-grade, weather-resistant materials to ensure a long-lasting, watertight seal.

Chimney flashing leaks are often caused by the expansion and contraction of materials during our wet-dry cycles, which breaks the waterproof seal. Our process involves removing the old, compromised flashing, inspecting the chimney structure and roof deck for rot, and custom-fabricating and installing new flashing from durable metals like aluminum or copper, integrated with a new waterproof underlayment for a complete seal.

During a Renton-specific inspection, we focus on high-failure points like ridge caps, flashing, and valleys where water runoff is heaviest. We look for cracked sealant, corroded or lifted flashing, moss growth that traps moisture, and any signs of granule loss on shingles from UV exposure. Identifying these early helps prevent the minor issues common here from turning into major leaks.
