If You Have An Active Leak, Call Us Now And We Can Tarp It Within 24 Hours

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

“Was impressed with the crew and the service. Arrived on time, ready to work. Did the work in less time than expected so saved me some real money. Work was well done and the process painless…would hire them again without question.”

—Leah W. | Seattle, Washington

“Repaired structural damage to a standalone carport. Work was done in a day, in and out. The construction foreman checked with me before doing any materials buys or rentals and kept me in the loop. I have used them before and will again.”

—Robert H. | Beaverton, Oregon

“Your guys were a class act and went above and beyond to help me with a job. I had questions afterward and the office staff was on it immediately making sure all of my concerns were addressed and handled. I will use SFW Construction again.”

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.
