A proper roof system design and installation is the first step in not only meeting applicable code requirements, but also in taking control over roof system durability and longevity. Building codes establish minimum requirements for weather protection, materials, insulation, reroofing, fire resistance, and other aspects of roof-system performance.
Designing and installing a commercial roof with long-term performance in mind may involve going beyond minimum requirements where the building, climate, and project conditions call for it.
Take control over roof system durability and longevity by:
- Using a roof cover board where appropriate
- Planning for effective drainage
- Installing traffic protection
- Designing for appropriate wind resistance
- Using a vapor retarder when necessary
- Managing installation moisture
Drainage is an important part of commercial roof design. Localized areas of poor drainage or ponding should be evaluated and addressed rather than relying on the roofing membrane alone to manage standing water. Depending on the roof design, tapered insulation, crickets, saddles, drains, scuppers, or other measures may be used to help move water toward appropriate drainage points.
For roof protection and worker access, walk pads, pavers, walkway membrane rolls, or elevated walkways may be appropriate around locations that are regularly accessed by maintenance personnel or other trades. These measures can help reduce unnecessary damage caused by repeated foot traffic.
Wind resistance is another important design consideration. Roof assemblies, perimeter details, edge metal, fasteners, and other components should be selected and installed to meet the applicable wind-uplift requirements for the building and location. In some projects, designers may choose assemblies or details that provide performance beyond minimum code requirements.
It may also be necessary to use a vapor retarder depending on the building use, climate, roof assembly, and expected moisture conditions. Uncontrolled moisture within a roof assembly can contribute to condensation, deterioration, reduced insulation performance, and other problems.
