Roofing Options for a Low-Pitch Roof
LESLIE: Charlene in Louisiana is on the line with a roofing question. What are you working on?
CHARLENE: I have a shallow roof on my house. They call it a 2:3 pitch. It’s not flat but it’s very shallow, OK? Almost no attic, about maybe 2 feet in there. I was interested in an aluminum roof, like a lifetime roof? And I wanted to know which would be better: that or a regular shingle roof, like an architectural roof.
TOM: You don’t have the pitch for an asphalt-shingle roof. You need to have at least a 3:12 or a 4:12 roof to put in shingles.
CHARLENE: Well, I have shingles on it now and they’ve been there for 20 years.
TOM: I’m telling you, you may but it’s not right. You can only put shingles on a roof that’s got a minimum pitch of 3:12 or 4:12. And if you’ve got them on there right now, count your blessings but it shouldn’t have been put on there. And any roofing manufacturer will tell you that.
If you – your options, therefore, are either to do, say, a rolled roofing or a rubber roofing or a metal roof, as long as it’s rated for that low pitch. And I think a metal roof is a great investment if you’re going to be there for the long haul. But that’s what I would invest in because with that low of a pitch, you probably don’t see it very much and you want to make sure that it’s really going to be watertight. And with a low pitch, you just can’t use an architectural shingle; it just won’t work.
