In December 2012, we installed an IB PVC roof in a duplex-condo in Brooklyn, NY. This new roof replaced an old leaking tar roof that was over 20 years old. The roof was leaking in multiple places, around skylights, and along separation wall flashing.
The new membrane installed was a 50-mil white IB PVC roof, with hot-air welded seam overlaps. The roof was mechanically fastened to the deck, using corrosion resistant screws and barbed plates, to provide a 130 MPH wind resistance.
We flashed two existing dome skylights, one roof hatch, and about 50 lineal feet of roof to wall / separation wall, using aluminum termination bar.
Why IB PVC Roof?
Although there are cheaper alternatives for a flat roof replacement, IB Roof is the best Flat Roofing material for residential and commercial application. IB Roof is a reinforced PVC membrane that features Fusion Hot Air welded seams and flashing. Hot air welding makes ALL the difference, when it comes to sealing the seams and overlaps.
Unlike traditional roofing materials that rely on sealants to join overlaps, hot air welding creates a permanent physical bond between two sheets of membrane. This means that two pieces essentially become ONE piece. The seam will never come apart (when done correctly) and is actually stronger than the material itself!
By comparison, other flat roof materials that are sealed with bonding adhesive will be leaking in just a few short years, when adhesive (glue) begins to fail. This will result in expensive roof and interior repairs, headaches for you – the owner, and potential frame/substrate rotting and mold.
