Stanwood Roof Replacement with GAF Timberline HDZ System

This Stanwood roofing project involved a full replacement using GAF Timberline HDZ shingles in Charcoal. The system included full ice and water protection, upgraded ventilation, and precision flashing. Designed for the Pacific Northwest climate, the new roof delivers long-term durability, improved moisture resistance, and a clean, modern appearance.

Project Overview

This single-family home in Stanwood, WA required a roof replacement due to aging composition shingles and the need for improved waterproofing. Given the area’s frequent rain and moisture exposure, the homeowner needed a system that could provide reliable, long-term protection. State Roofing & Exteriors completed a full tear-off and inspected the roof deck, replacing sections with CDX sheathing where necessary. A full GAF WeatherWatch ice and water shield was installed across the entire roof deck, along with GAF FeltBuster synthetic underlayment for enhanced moisture defense. The new roofing system features GAF Timberline HDZ shingles in Charcoal, paired with Pro-Start starter shingles and Z Ridge hip and ridge components. New ventilation was installed, including RVO exhaust vents and upgraded airflow solutions. Additional improvements included new lead pipe boots, metal flashing at all critical areas, and resealing of penetrations and skylights.

Results

The completed project provides a significant upgrade in both performance and appearance. Full-deck waterproofing and improved ventilation help protect against leaks, mold, and long-term moisture damage common in Stanwood’s climate. The Charcoal shingle color offers a sleek, updated look that enhances curb appeal while maintaining durability. With proper installation and high-quality materials, the homeowner now benefits from a roofing system built to perform reliably for decades with minimal maintenance.
