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’s roofing and waterproofing experts have reviewed thousands of system failures and have an intimate knowledge of a wide range of roofing systems—from historic clay tile to the latest in green roofs and sustainable design, to plaza decks, and foundation waterproofing systems in positive and negative side applications.

Building owners know the importance of a water-tight structure. WJE roofing and waterproofing professionals provide a holistic approach to each project by addressing the roofing or waterproofing system, the supporting structure, and integration details that tie-in with enclosing or perimeter elements.

WJE’s commitment to every project carries through the Construction phase. WJE’s roofing and waterproofing professionals work hand-in-hand with contractors to ensure design concepts are met and the building and its contents are protected from the devastating effects of water.
