We Provide Professional Flat Roof Repairs In Portland, Oregon

A leaking or damaged flat roof could be due to a variety of different reasons, including the age, an unexpected storm, regular wear-and-tear, construction defects, dry rot, etc. Dry rot occurs when water gets past the protective exterior products of your roof and gets trapped, spreading throughout the wood frame. As a result, you can end up with water damage, mold, mildew, and eventually, if left untreated, dry rot. If you suspect your flat roof has dry rot or needs a repair, make sure to hire a flat roof repair contractor who can do the job right the first time.

Protect your roof from damaging moisture. There’s still time to get your repairs done, so no more damage occurs.

What Our Customers Say

December 2020
“We wanted SFW Construction to repair the siding on our garage, which turned into rebuilding our garage. They let us know the scope of work and explained everything clearly. I would use them again for any future projects as I was thrilled with the work.”

—Ann C. | Portland, OR

December 2020
“When it came to the actual construction phase they were great about discussing the scope so that we were all on the same page about time and budget. Their attitude was always good and they completed the work with skill well within my timeframe.”

—Miranda H. | Portland, OR

December 2020
“SFW did a great job replacing the rotten siding on my garage. They arrived to work on time every day and worked hard. The lead carpenter was knowledgeable and described the job in detail before they started. I would recommend SFW to a friend or neighbor.”

Flat Roof Options

If a flat roof replacement is in the cards for you, there are a few different choices, each with their advantages and disadvantages:

  • Modified Bitumen: Cut in 3-foot strips and made from an asphalt composite, this is frequently found on residential flat roofs.
  • EPDM (ethylene propylene diene monomer): This rubber roofing comes in large sheets and works well on large buildings.
  • PVC: A white, single-ply thermoplastic material that is extremely durable and reflects heat nicely. Often used on large commercial buildings.
  • TPO: A newer type of single-ply thermoplastic membrane, this one has a fabric feel to it, good durability, and is relatively inexpensive.
