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 workmanship warranty does Flow Roofing provide?

Flow Roofing provides a 10-year workmanship warranty on standard roof packages. A lifetime workmanship warranty is available on MaxFlow Systems installations. Every project is also backed by the manufacturer warranty behind the materials installed. Flow Roofing is a Malarkey Certified Premium Installer which allows us to offer extended manufacturer warranties including No Dollar Limit coverage that non-certified contractors cannot provide.

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.

Cost of Metal Roofing in Portland, Oregon

Metal roof cost depends on roof size, material type, and project complexity. Standing seam metal roofing for a typical home runs $20,000 to $45,000 depending on roof complexity. While metal has a higher upfront cost than asphalt shingles, it offers long term value through 40 to 60 year service life, energy savings, and reduced maintenance. We provide written estimates with no obligation.

Custom Metal Fabrication

There is only one word that adequately sums up our metal roofs. Custom. Using our standing seam roll forming equipment, every roof is individually produced to order. The roof is constructed from precisely cut and sized panels. Our equipment allows us to extrude panels right at the construction site, which means panels are produced to exact length with no field seams.

For homes, we install a 26 to 22 gauge snap lock hidden screw metal panel roof system, sized on the job. Customers can choose from a wide range of colors to match their home's color scheme.

Like every replacement we install, the old roof removal is documented with photos or video. All existing decking is re nailed to current code and pattern.
