Avalon Bothell Commons: A GAF case study

By GAF.

For this mixed-use community, Chinook Building Envelope Services needed a manufacturer that accommodated the large scope of the project and its different designs efficiently and effectively.

Easing the paperwork burden for contractors

The Avalon Bothell Commons in Washington is the next big residential and mixed-use community with more than 675 apartments, 70 townhomes and one club building with a fitness center and pool. As the roofing contractor, Chinook Building Envelope Services needed a manufacturer that accommodated the large scope of the project and its different designs efficiently and effectively. 

Simple, efficient warranty system

Along with the frequent weather challenges in the Pacific Northwest, the large project required multiple mobilizations for a year and half in its first phase due to its extensive scope of work. Given the amount of coordination needed to ensure smooth operations, AvalonBay Communities, the developer, needed comprehensive warranty coverage on its products to make things as efficient and simple as possible. 

Taking advantage of GAF’s Silver Pledge Limited Warranty that covers the various GAF steep-slope products used in the roofing system, Chinook helped to create a single, comprehensive system for AvalonBay Communities – streamlining the process for any future roofing needs. 

GAF offers a robust portfolio of steep-slope and low-slope roofing products backed by strong warranty and guarantee protection, which allows for coverage of both the steep-slope and low-slope roofing systems by a single manufacturer. Property owners can obtain a steep-slope warranty and a low-slope guarantee from a single source.

Across the different buildings and individual townhomes, Chinook installed steep slope systems using products such as GAF Timberline HDZ® Shingles,Feltbuster® Synthetic Roofing Felt and WeatherWatch® Mineral-Surfaced Leak Barrier, and low slope roofing systems using products such as GAF EverGuard® TPO 60 mil Membrane, EnergyGuard® Polyiso Insulation and DensDeck® Roof Board. GAF’s Silver Pledge Limited Warranty provides coverage for the steep slope roofing materials and GAF’s EverGuard® Diamond Pledge™ NDL Roof Guarantee provides coverage for the low slope roofing, to help keep both roofing systems performing well throughout the years.

“On a big project like this, you want a single place where everyone can go for all your roofing needs. Given the different types of roofs installed on this project, we were looking for a single manufacturer that could supply the materials and provide strong coverage for the entire roofing project, and GAF delivered on that along with its high-quality performance,” said Duane Hadley, president of Chinook Building Envelope Services. 

Avalon Bothell Commons is set to finish the first phase in 2024 with a phase two expected after for more homes in the Bothell community.
