LESLIE: Keith in New York is calling in with a roofing question. How can we help you today?KEITH: I have a problem with a flat roof on a building and …TOM: Well, you’re not alone. (Leslie and Tom chuckle)KEITH: OK. Well, this one I can’t change.TOM: OK.KEITH: It’s eight inches of steel, reinforced concrete.TOM: OK.KEITH: And after about 50 years – which I haven’t been part of it but going back a long time – the edges are starting to erode away.TOM: OK.KEITH: When I was down in Florida, I noticed some people were putting roof-overs on a lot of their trailers there.TOM: OK.KEITH: On the original ones.TOM: Yes.KEITH: And these were a rubberized type or synthetic membrane of which they put Styrofoam over the top and then put this wonderful stuff and wrapped it all around and it’s UV-protected and all that kind of stuff and I …TOM: Yeah, they’re probably EPDM roofs; they’re like sort of a rubber membrane.KEITH: EPDM. I …TOM: Yes.KEITH: Somebody had told me once of Firestone.TOM: Well, Firestone is one of the manufacturers. They’re out in …LESLIE: Of that type.TOM: They’re based in Indianapolis. But there are a number of manufacturers.KEITH: And I’m trying to find out who I have to contact.TOM: Keith, the best way to find a commercial roofing supplier in the city is to simply Google it. There are a number of them that we’re aware of. One that seems to be somewhat prominent is Allied – Allied Commercial Roofing. They are in New York but they serve New York, New Jersey and they specialize in all sorts of commercial products: flat roofing, tear-offs, metal roofs and so on. And they also happen to be the distributor of Firestone.KEITH: Well, that – you have answered my question. What does EPDM stand for?TOM: Ah, you’re asking the tough questions now. (Leslie chuckles)KEITH: (chuckling) Sorry.TOM: This is like the home improvement expert of the SAT question, Leslie. Well, it actually – believe it or not – I do know what it stands for.LESLIE: Well, the “E” has got to be like ethylene or something.TOM: Yeah, well, actually you’re right; it’s ethylene, propylene, diene monomer. It’s basically a very high-density rubber used for roofing products.LESLIE: Mm-hmm. And it’s got to be professionally installed; I mean, this isn’t something you can buy, you know, at the local home center.TOM: Not a DIY project and, in fact, I’m not surprised he’s having problems with a leaky roof – leaky flat roofs – because flat roofs, that’s what they do; they all eventually leak and they leak a lot more frequently than sloped roofs and I think that an EPDM product is the solution for you.KEITH: OK. Thank you very much.TOM: You’re welcome. Thanks so much for calling us at 1-888-MONEY-PIT.
