Commercial Flat Roofing Experts in Portland, Tigard & Beaverton
Precision. Experience. Results.
Cascade Roofing Portland has been a trusted name in commercial roofing for more than 65 years. Our skilled employees—not subcontractors—bring decades of hands-on experience to every project. Many of our craftsmen have been with Cascade Roofing for over 30 years, and that level of loyalty and expertise shows in every flat roof we install.
The Precision Demanded by Commercial Flat Roofs
Commercial flat roofing is one of the most technically demanding specialties in construction. Unlike steep residential roofs, flat roofs must be designed and installed to handle the Pacific Northwest’s heavy rainfall and variable temperatures. Even a small mistake in drainage slope, insulation, or seam sealing can lead to costly problems down the road.
Every successful installation requires:
- Mastery of flat roof systems such as torch-down modified bitumen, PVC, and single-ply membranes.
- Skill in applying proper slope and drainage techniques to prevent ponding water.
- Knowledge of insulation layers and vapor barriers for thermal efficiency.
- Strict safety practices—especially on large or multi-story buildings.
