Our Approach
The success of any roofing or waterproofing system depends on well-conceived and constructed details. Whether the structure has a low- or steep-slope roof system, a plaza deck with various hardscape elements and water features, or a below-grade foundation system in variable soil conditions under hydrostatic pressure, the selection of the right product and its detailing in the context of the project application is of paramount importance. Attention to even the smallest detail(s) often can dramatically impact the performance of a roofing or waterproofing system.

WJE is an international firm with twenty-two offices nationwide, including locations in Seattle, San Francisco, Los Angeles, and Denver. We are often called upon to respond to roofing and waterproofing problems on short notice and can have staff available on site anywhere in the western U.S. the same day, if needed.

Many of our roofing experts are RCI Roofing Consultants or Observers and registered architects or engineers.
