A reinforced, single-ply PVC membrane was examined five years after being applied over a leaky, built-up, bituminous membrane. The bare PVC membrane was dirty, poorly drained and littered with broken glass, nails and such, yet no flaws were evident or leaks reported. Even at 0 F the PVC was quite flexible. Diagonal wrinkles at a parapet wall were attributed to workmanship other observations suggested that membrane shrinkage had not occurred. The membrane has functioned well for five years and appears to be in good condition. Author
