Shayla: Welcome to the Roof Life of Oregon podcast. I’m talking today with Daniel. Daniel, tell me about architectural shingles on low-slope roofs. We’re seeing that. Is that okay to do?
Daniel: It’s not unless it’s done correctly. The old style of three-tab roofs could be used on a lower slope roof, because of the way they traffic water off of the roof. Modern architectural shingles can’t do that. They’re a tighter connection where they come together and the manufacturers say don’t use them on a low-slope, because as they come down, the water gets between the two shingles, where they come together, and it can it work its way under the shingles.
So let’s talk about modern houses. Architects design some beautiful houses. They really do. Unfortunately, architects don’t think about water flow a lot of times. We live in Portland. It rains a lot here. You’ve got trees, debris, moss, and water flow. And if you have an architect that designs a beautiful house, the builder builds the house, but then they hire the cheap contractor to keep their costs down to put the roof on, they’re not going to think about that water flow and so, we’ve talked about this before, it’s called a dead valley. They’ll have two great big dormers coming down into this low-slope area. And low-slope, the easiest way to figure that out is for every twelve feet the roof goes across, it only rises one foot. So it’s really low. The water just can’t get off the roof and you’ll have a contractor that’s the cheap guy say, “Well, I’m going to put this roof on and move on and they’re not going to see me again.” So they just put the architectural shingles in that area and it doesn’t leak for awhile. You may get five, seven, maybe ten years and then the leak happens.
I had that just recently this week for a leak and I went up there and looked at it and instantly said, “Well, why did he even use these shingles? You’re not allowed to use them in this area.” The manufacturer says don’t do do that. So on these low-slope roofs, if you’re going to use an architectural shingle, it has to be a certain pitch and there’s a certain way to go on, or a membrane needs to be used in that area. We just need to work around what the manufacturers, what the builders, and what the architects design, and do the correct shingles or membrane in that area, not an architectural shingle.
Shayla: Does that mean someone that’s going to look at a brand new house that’s just been built, do they need to hire you guy then to come check out the roof and make sure everything’s good to go before they purchase the home?
Daniel: That’s a really good idea. We look at real estate inspects or roof inspects before someone buys a used house. We never talk about brand new houses needing a roof inspection. That’s a really good idea to have us come out. Your house is being built and as it’s being built, why not have a third party come take a look and say, hey, hang on, this might be an issue years later.
