Roof to wall flashing is critical to the performance of every single-ply roofing system. These transition points, where the flat part of the roofing system is tied into the parapet wall, are potentially vulnerable areas for water intrusion. Following the requirements for proper flashing can help ensure that the roof system offers better protection.

A typical PVC roofing system will consist of insulation board and membrane over the structural deck. As with other single-ply roofing systems, there are multiple ways to fasten the PVC roofing membrane.

When a building owner asks you if they need a commercial roof repair or replacement, your assessment of the roof's condition hinges on a few key areas. Veteran commercial roofing experts Dave Scott and Wally Brown share their roof inspection expertise in GAF's Roofing It Right with Dave and Wally: Roof Project from Start to Finish video series to help you assess the condition of critical areas on the roof.

Is thermal mass a lost art form after centuries of use in temperate regions?In building design, the thermal mass of a building enables it to store heat, providing "inertia" against temperature fluctuations. It reduces the impact of external daily temperature swings on internal heating and cooling requirements. This thermal inertia has been an on-off again topic of discussion for some time. Proponents of adding thermal inertia point to Mediterranean area buildings constructed with thick stone walls and ceramic tile floors etc. Such buildings have kept occupants cooler than lighter weight buildings in many temperate areas of the world for centuries. In the quest to improve the energy efficiency of buildings, further gains are becoming increasingly harder to come by.
