Renton Roof Replacement with CertainTeed Landmark System

This Renton roofing project included a full tear-off and replacement using CertainTeed Landmark shingles in Moire Black. The system features full ice and water protection across the entire roof deck, upgraded ventilation, and precision flashing. The result is a durable, weather-resistant roofing system built to withstand the Pacific Northwest climate.

Project Overview

This two-story single-family home in Renton, WA required a roof replacement due to aging materials and the need for improved moisture protection. With the region’s consistent rainfall and damp conditions, the homeowner prioritized a system that would provide superior waterproofing and long-term reliability. State Roofing & Exteriors removed the existing roofing layer and inspected the OSB roof deck to ensure structural integrity. A full ice and water shield was installed across the entire roof deck, providing enhanced protection beyond standard coverage. Synthetic underlayment was added for additional moisture resistance. The team installed CertainTeed Landmark shingles in Moire Black, along with starter shingles and hip and ridge components. All roof penetrations were sealed using no-caulk pipe boots, and new metal flashing systems were installed, including step flashing and valley metal. Bird blocking was incorporated at the eaves to improve ventilation control and prevent pest intrusion.

Results

The completed roofing system delivers superior protection against heavy rain and moisture infiltration, a key concern for homes in Renton. Full-deck ice and water coverage significantly reduces the risk of leaks, especially during prolonged wet seasons.The Moire Black shingles provide a clean, modern aesthetic that enhances curb appeal while maintaining durability. With a CertainTeed 5-Star Warranty, the homeowner benefits from a 25-year workmanship warranty and a 50-year non-prorated material warranty, ensuring long-term peace of mind.
