Tacoma Roof Replacement with GAF Timberline HDZ System

This Tacoma roofing project involved a full tear-off and replacement using GAF Timberline HDZ shingles in Charcoal. The team installed updated flashing, underlayment, and ventilation components to improve durability and weather resistance. The result is a long-lasting, high-performance roofing system designed to handle Pacific Northwest rain while enhancing curb appeal.

Project Overview

This single-family home in Tacoma, WA required a complete roof replacement due to multiple aging layers and signs of wear. The existing system included up to five layers in certain sections, which can trap moisture and compromise structural integrity over time. Given the region’s frequent rain and moisture exposure, proper waterproofing and ventilation were critical.State Roofing & Exteriors performed a full tear-off down to the deck, followed by a full redeck to ensure a solid foundation. The project included installation of GAF FeltBuster underlayment and WeatherWatch ice and water shield at all critical areas such as valleys, penetrations, and around the chimney. New metal flashing systems were installed, including step flashing, valley metal, and chimney flashing with counter flashing for long-term leak protection.The roofing system was completed with GAF Timberline HDZ shingles in Charcoal, along with starter shingles and hip and ridge components. Additional work included sealing all exposed fasteners, reinstalling roof penetrations, and ensuring proper drainage and water diversion.

Results

The new roofing system provides significantly improved protection against Tacoma’s wet climate, reducing the risk of leaks and moisture intrusion. The full redeck ensures structural stability, while upgraded flashing and underlayment systems create multiple layers of defense.Visually, the Charcoal shingles modernize the home’s appearance, adding contrast and enhancing curb appeal. The installation meets manufacturer specifications, supporting long-term performance and warranty eligibility. The homeowner now benefits from a durable, low-maintenance roofing system designed to last for decades.
