Beauty and beast
As the highest performance liquid-applied roofing membrane available, GE Enduris isn’t just a great looking coating – it performs even in the most challenging climates and sea-side location.
At about five years old, the existing roof coating was starting to fail. There were leaks as well as rusted areas – particularly on the panel edges. It was time for a refresh for all the roofs in the complex.
“We considered several solutions. “GE Enduris was the best value – price and performance. We trust the GE brand and the silicone performance promise,” says Ferens Badenszki, the Maintenance Manager for Villa Caletas, a large complex with 10,000 m2 of roof area.
GE EndurisTM is a simple solution that provides up to twenty year warranty. The application started with GE EndurisTM Seam Sealant to joints, gaps, and areas of where dissimilar materials meet. This ended the persistent leaks. Next, the GE Enduris coating was applied to the entire surface for long-term protection against the elements and ponding water.
Because all GE Enduris components are 100% silicone, there was no worry of failures from the intersection of dissimilar materials. “Now the customer has a seamless roof with little annual maintence needs,” says Jeffry Martinez, Project Supervisor at distributor MegaLineas. “Costa Rica is a challenging environment. It’s hot and humid, which can lead to metal rust with lower perfromance coatings. High temperatures, interrupted by frequent and unexpected rain, can cause huge roof temperature changes in just a few seconds. This is challenging for a metal roof – especially where panels overlap and at penetrations.”
The owner immediately noticed lower temperatures in the rooms and common areas. Although not yet quantified, this can save energy costs in conditioned spaces and very significantly increase comfort in unconditioned spaces. In fact, the owner verified the lower temperatures on the roof as well by touching them at noon – they were still cool.
There are application benefits as well. “During the four-week project, we lost only two days to rain,” says Ferens Badenszki. He explains, “If it had been an acrylic coating, we would have lost weeks. It rains here every afternoon! A quicker and more predictable installation meant savings for us and less interruptions for our guests.”
“As you know, most acrylics cannot be applied if rain is expected within 24 hours,” says Ferens.
“From several options, we chose GE Enduris. It was the right combination of price and performance.”
