Roof Truss Supply – Puget Sound’s Lumber and Truss Supplier for nearly 50 years.

Roof Truss Supply, Inc. is a locally owned, family-based company focused on serving professional contractors, single-family production, multi-family and commercial builders in the Puget Sound region of Western Washington. Being a family-owned business, Roof Truss Supply recognizes our customers are the #1 priority, not shareholders or a companies stock price like some of our national competitors.


Besides our lumber and our component manufacturing facilities, Roof Truss Supply owns and operates two door and millwork manufacturing facilities strategically located in the north and south Puget Sound region. This allows us to properly service our customer base, regardless of the area they build—offering pre-staining at our primary location.
