How to Design a Wind-Resistant Single-Ply Roof System (3 of 4)

Another tip from Stan Graveline, VP at Sika Sarnafil.

Make sure to combat air infiltration from within. For certain building types, the roofing system should be designed to resist pressure from both the exterior and interior. For example, buildings operating at positive internal pressure, such as cleanrooms, highly sensitive labs, and high rises, are susceptible to roof damage caused from the pressure within.The typical remedies for resisting internal pressure include beefing up the roofing system structurally, incorporating an air barrier/vapor retarder at the roof deck level, and sealing joints, transitions, and penetrations throughout the roof deck.
