Residential and Commercial Flat Roof Contractor

We’re Portland’s Flat Roof Experts

It’s not an understatement to say that Portland sees its fair share of rain. And rain is the enemy of the thousands of flat roofs adorning commercial buildings and homes across the Northwest. Water tends to pool and penetrate seams in the membrane, flashing, and wherever it can find. Next thing you know, you have a leak. And if your damaged roof has been neglected, there’s a good chance that rot has invaded the wood underneath.

While many roofing contractors can handle leaks, most are not equipped to handle rot and other issues that commonly accompany a damaged flat roof. What’s worse is that some will knowingly roof right over the top of problem areas in order to complete the job quickly and get paid.

No Need to Call Another Contractor!

SFW Construction, on the other hand, is one of the few roofing contractors able to handle any of the issues that may be hiding under your low-slope roof. If dry rot, for example, is discovered during the roofing process, our dry rot experts can take care of it quickly and properly so the integrity of your building’s structure isn’t compromised down the line.

Flat Roof Repairs Require Flat Roof Specialists

Flat roofs are a completely different animal than your typical, standard-pitch residential roof. As such, it’s important to hire a commercial roofing company with plenty of professional experience working with flat roofs, specifically and is familiar with all of the nuances. SFW Construction specializes in the repair and replacement of various types of commercial and residential flat roofing, including TPO, PVC, EPDM, and Bitumen. Our flat roof professionals have the expertise, they’re GAF-certified, and they’re 100% dedicated to providing our customers with a first-class roof job that will protect their homes and commercial buildings for many years to come.

Should Your Flat Roof Be Repaired Or Replaced?

As you might guess, the answer to this question depends on the age and condition of your roof, but also the type. During our comprehensive initial inspection, we will carefully check for any issues around seams, flashing, chimney, skylights, and other attachment points. We’ll look for standing water, cracking, and general deterioration that might be caused by aging and/or the elements. Taking all of this into account, as well as the roof type and its life expectancy, we can recommend whether a repair or a replacement makes the most sense for you. We might find, for example, that a rubber (EPDM) roof which is 12 years old and pulling away at attachment points should be completely replaced, whereas a 20-year-old, single-ply PVC roof that’s leaking at the seams might need just a simple repair.

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.
