After 25 years of enduring the Texas sunshine the roof had a cracked and deteriorated fiberglass membrane top cap. In addition, hail had damaged the existing membrane allowing for leaks. Since the owner had the building for sale and couldn’t sell it in the existing condition, and a reroof was double the cost, offering a warrantied leak-free solution without performing a complete tear-off, would prove to be beneficial for the seller and to future owners of the building.
The Griffith Roofing Company team decided a recoat with GacoFlex S20 was the best solution for Town East Crossing. Avoiding a tear off would greatly reduce labor and material costs, and coating the existing roof would reduce the building owner’s and contractor’s risk to future leaks.
Due to the dry and cracking asphalt the team removed all loose and brittle tar. The GacoFlex S20 Series Solvent-Free 100% Silicone Coating was sprayed and back rolled to ensure all cracks were filled to ensure water tightness for years to come.
The roof was washed with GacoWash Concentrated Cleaner and allowed to dry. Then the GacoFlex E5320 2-Part Epoxy Primer/Filler was applied. After that all seams and penetrations were sealed using GacoFlex SF2000 SeamSeal Solvent-Free Silicone Sealant. After allowing sufficient time for the SeamSeal to cure, the GacoFlex S20 Series Solvent-Free 100% Silicone Coating was installed to create a waterproof membrane over the existing roof. Finally, GacoFlex SF2036 WalkPad Solvent-Free SiliconeWalkway Systems were installed.
