We have a large warehouse with a 90 year old copper clad tin, standing rib roof that leaks like a sieve. We are in Central Florida and are trying not to sell the farm to re-roof the thing!
Do any of you have any experience in coatings like the foam coating w/ Elastomeric? It sounds good to us, though it is extremely expensive, around $150,000.00. We just do not know how it will hold up to the Florida heat.
Our building is an old citrus packing house. The roof is not flat, but there is not a very high pitch. There are 15 skylights that will have to be replaced. The building is around 25,000 square feet.
We have spent hundreds of hours trying to patch this roof. We’ve used Silver Dollar coating, painting all the roof two or three times. No success. We have used Elastomeric patch. No success do to the seemingly miles of 1.5" standing rib joints that could be leaking. It seems like a football field in size, when you are up there and it is an endless job of scraping, patching and coating. So we are thinking that the foam coating, that would be topped with the UV blocker Elastomeric may be worth it. However, we really do not know how many years it could hold up in the Central Florida heat. Our fear is that we would spend the $150,000+ and then it would start cracking in a couple of years.
I’d love to know about any of your personal experience with it! Thanks ahead of time for any input whatsoever!
