Frequently Asked Questions

What is the best flat roof material?

For most Portland flat roofs, we recommend TPO membrane for its durability, energy efficiency, and 20+ year lifespan. Torchdown is a great option for smaller areas or repairs.

How do you handle drainage?

Proper drainage is critical for flat roofs in Portland. We design systems with adequate slope (minimum 1/4" per foot), interior drains or scuppers, and overflow protection.

How long does flat roofing last?

TPO and quality torchdown systems last 20-30 years with proper installation and maintenance. Our 25-year workmanship warranty ensures your flat roof is built to last.
