Dealers Supply traces its roots back to a small feed and seed distributor serving the Portland, Oregon area beginning in 1920.
As Portland grew the demand for construction was cause for our company evolving away from agricultural supplies and toward the supply of building materials.

Early in our history the owners of Dealers Supply recognized that success of their company depended on highly motivated and dedicated employees. Their generous decision to share in the profits of their business has been the driving force behind our growth.

Today our services include: knowledge, product inventory, and delivery services in the areas of residential roofing, commercial roofing, building envelope (below grade waterproofing and air barrier), as well as our own in-house tapered insulation design specialists.

Dealers Supply stocks the best product lines in the industry.
Our inventory in over 400,000 square feet of centrally located warehouse is unmatched in the Northwest. Our extensive fleet of delivery vehicles includes: flatbed, tractor trailer, maxi tractor trailer, bulk asphalt carrier, ladder hoist, boom hoist, and crane service. Most importantly our friendly staff is ready and willing to help you with all of your roofing, waterproofing, air barrier, and tapered insulation needs.

With high quality product lines, the largest inventory of any distributor location in the Northwest, and dedicated staff who share in the profit of the business, we offer the contractor a level of service that is unmatched.
