Topic tags/keywords: question resource tip trick

I’m making a hobbit hole chicken coop for a friend and am kind of halted at my roofing approach. At first I considered overlapping lengthwise planks out of 1×6’s. But now I think I want to go traditional roofing shingles (the tar kind with adhesive backing). The problem is how to attach them. I was going to buy 5mm underlayment sheets and just tack them up along the curve but upon further research I found that the minimum requirement for roofing shingles is 18mm or .7”. There’s no way 3/4 plywood would even dare to be bent on that curve (I don’t think) without cutting relief dados. I then thought maybe running 1×4’s lengthwise might work but was hoping to avoid that method. Thoughts ?

T & G 1X4s would work well. The interlocking feature would make the boards less bouncy when fastening the shingles. Even better if you used a roofing nail gun.

well it’s hard to tell from the pic, but I think 1’2” ply would bend right around there. other wise use your 1×6 or 1×4 idea,(shiplap would be best) but will cost you much more. I’m not familiar with an adhesive back shingle. around here we use asphalt shingles, nail them down and they will stick down in the sun. You can also get steel for this roof.

On a curve like that 1/8” plywood or paneling… whatever’s the right price will be fine. Just be sure to anchor it good to the braces at the edges. The arching effect will give it strength say.. if it should snow on it.

Turn your iphone so the home button is under your right thumb, then take / post pictures. They’ll be proper for LJs that way, no additional work needed.

You might want to look at some of the stuff on the web related to making teardrop campers. There are several techniques for forming the outside teardrop roof that might give you some ideas.
