This Lake Stevens roof replacement project in the Preserve at Lake Cassidy neighborhood features a CertainTeed Landmark TL shingle system installed by Pinnacle Roofing Professionals. The project also included a PVC membrane dead valley repair and skylight replacement to address drainage and daylighting needs.
Project Overview: Lake Stevens Landmark TL Roof Replacement
Located in Lake Stevens, Washington, this residential roof replacement started with a full tear-off of the old composition shingles. The Pinnacle Roofing crew then installed a complete CertainTeed Landmark TL roofing system, a triple-layer laminate shingle designed to replicate the dimensional look of cedar shake while delivering strong wind and water resistance for the Pacific Northwest.


Dead Valley Drainage Repair and Skylight Replacement
Dead valleys are low-slope roof areas where two roof planes meet and water drains slowly. On this Lake Stevens home, the dead valley was repaired with a PVC membrane for added waterproofing protection. The crew also replaced the existing skylight to ensure proper flashing integration with the new Landmark TL roof.
