Vinyl Gives New Life to Leaky Hospital
SITUATION: Plagued with persistent roof leaks at Powell Hospital in Powell, Wyoming, hospital administrators knew swift repair action needed to be taken. A leaky hospital roof is more than just an inconvenience – it not only can cause damage to sensitive medical equipment but could also affect patient health. Hospital administrators and facility managers immediately set out to find a new and environmentally friendly roofing material.
Vinyl as the Sustainable Roofing Solution
The majority of the roof leaks were due to failure of the existing roofing system around parapet walls, flashings and roof details. Gravel ballast on top of the roof made finding and then repairing the leaks even more difficult. What was needed was a roof system that would be able to withstand the harsh Wyoming weather, while reflecting sunlight and reducing cooling costs – and the urban heat island effect.
After an analysis of available roofing material and their accompanying warranties, the team tasked with solving the hospital's roofing problem chose a Duro-Last roofing system made of prefabricated, single-ply, white thermoplastic vinyl. The fact that 80-85 percent of all seams and detail work would be hot-air welded was what convinced the hospital that this product would prevent a repeat of the original problems.
In addition, vinyl's properties make it easy for the installer to ensure complete seam welding by visually monitoring the melted vinyl bleed-out at the edge of the seam during the hot-air welding process, a key quality assurance indicator. The finished seams resist thermal cycling, freeze/thaw effects, ponding water and all other aspects of Wyoming's extreme weather conditions.
“I couldn’t be happier with the Duro-Last vinyl roof,” said Chris Cooper, Powell's facility manager. “It looks great with its new durable, virtually maintenance-free roofing system.”
