The right system for the building
Commercial roofs in the Northwest deal with months of rain, wind off the water and moss. We recommend a system based on your roof's slope, drainage, use and budget.
| System | Best for | Why choose it |
|---|---|---|
| TPO & PVC single-ply | Flat and low-slope roofs on retail, office and warehouse buildings | Heat-welded seams for continuous, watertight coverage; reflective white membrane |
| Metal roofing | Industrial, agricultural and mixed-use buildings | Long service life and strong performance in wind and rain |
| Architectural shingles | Apartments, condos, townhomes and steep-slope commercial | Cost-effective, with GAF system warranties available |
