LeakMaster's Opinion

Metal Roofs are also in vogue because they can be also be made to last the lifetime of your structure. Standing Seam roofs need very little maintanence until their Kynar 500 coating starts to wear out. When is that? It's hard to say in Hawaii where the UV varies a lot from Hawaii Kai to Manoa, but some Manufacturer's go as long as 35 years. Others, like MacSteel, are more cautious and vary their Warranty depending on how close you live to the salt water, and which way the trades blow. For instance, on the beach in Kailua is not considered to be optimum. None the less, whenever your coating does fade it can be recoated with a new protective coating at a reasonable cost, because you don't have to reinforce the panel seams and screw heads--like you do with Exposed Fastener roofs, which are less expensive. Pay me now, or pay me later... Like death and taxes, roof maintanence is inevitable.
