Licensed Oregon CCB #218471, Washington FLOWRR*791Q4.

What is the best commercial roofing system for Portland Oregon?

For flat and low-slope commercial roofs in Portland Oregon, TPO and PVC membranes are the top choice. Both handle Oregon's 43 inches of annual rainfall well and last 20-30 years when properly installed. TPO costs $7-$12 per square foot. PVC costs $9-$14 per square foot and offers superior resistance to ponding water. For steep-slope buildings, metal roofing is the longest-lasting option at $12-$18 per square foot.

How do I know if my roof needs repair or full replacement?

If your roof is under 15 years old with isolated damage, repair is usually the right call. If your roof is over 20 years old, you have recurring leaks, or repair costs are becoming frequent, replacement is likely the better long-term investment. Flow Roofing provides honest written assessments and will recommend repair over replacement when that is the right answer.

What is a No Dollar Limit NDL warranty on a commercial roof?

A No Dollar Limit NDL warranty is the highest level of commercial roofing warranty available. Unlike standard warranties that cap the payout, an NDL warranty covers the full cost of repair or replacement for the duration of the warranty period, typically 15-35 years. NDL warranties are transferable if the property is sold. Flow Roofing is a certified installer and can offer NDL warranties that non-certified contractors cannot.
