Negative Wind Lift

​

Wind uplift is mostly associated with roof shingles, but nearly all roof systems are vulnerable to negative wind lift.  The more elements involved in a roof system, the more opportunity for failure.  Wind uplift can occur within low-slope roof assembly and shingle roofs.  Fasteners can be pulled from the deck, or the roof membrane can come loose from its substrate; both are problems.  While uplift on a shingled surface is fairly easy to show, with low slope roofs, GBI professionals use an uplift chamber under ASTM and/or FM standards to show roof system failures due to exposure to high winds.
