General
Steep slope roofing is a term most commonly applied to roofs having a slope of 1:3 (4" in 12") or greater. Generally, the materials installed on steep roofs perform the same function, they provide a “water shedding” roof system. These systems do not “waterproof” the roof, but divert water away from the roof into the drainage system.
The components of a steep slope roof are usually relatively small units designed to be overlapped and installed in courses. Despite the number of gaps or joints in the roofs, water will not usually penetrate the system unless the flow of water is impeded. Care must be taken to ensure no element of the roof system “bucks” water.
Steep slope roofing systems included in the RoofStar Guarantee Program are:
For further information and installation specifications, consult the RoofStar Guarantee Standards in the Steep Slope Roofs section of this Manual.
Some flexible membrane roof systems are suitable for steep slope applications. For standards and material requirements, consult the Low Slope Roofs section for RoofStar Guarantee Standards, and Accepted Materials for membrane manufacturer's requirements.
