Help Cool Down a House with UV Reflective Roof Paint
LESLIE: Buck in Texas, you’ve got The Money Pit. How can we help you today?
BUCK: I was calling to ask a question about a built-up roof, about 4,000 square foot. I was thinking about taking and putting a coating on top of it. No insulation in the attic. And was wanting to know if it really would actually defer the heat in the lower floor by putting a brilliant-white roof coating on top.
TOM: Well, those types of roof paints do have UV reflectors in there and they’re designed to make the roof cooler and certainly, it will be a heck of a lot cooler than the black roof that you’re starting with. So I think that that’s probably a good idea in your situation, especially being in such a warm part of the country, Buck.
BUCK: Any particular product brand that you can suggest going on top of tar?
TOM: No. But make sure it’s a roof paint. I mean typically, you use a fibrous aluminum paint for something like that. What you really want to look for is the UV reflectivity of it because the more UV it reflects, the better the job it’s going to do.
And by the way, it will also extend the roof life, as well, because the cooler the roof is, that means less of the oil is going to evaporate out of the asphalt and it’ll last a lot longer.
BUCK: OK. Good.
TOM: Buck, thanks so much for calling us at 888-MONEY-PIT.
