Framing A Curved Roof

We just put a curved roof on the new house we’re building- Let me show you exactly how we did it.
The truss company built trusses for this porch, but it was up to us to make the curve.
The plans call for a 22-foot radius on this roof.
To figure out the radius we used some string and scrap pieces of OSB.
We stretched the string out 22 feet, the length of the radius, then, tied a loop on the end to hold a marker.
Keeping the string tight, I traced the curve onto the OSB.
The framers traced the pattern they made onto ¾” subfloor and cut it out with a circular saw.
Next, they use glue and screws to laminate two pieces together, making them an 1 ½” thick- so they’re really strong.
They used a grinder with a flap disc to smooth out any unevenness.
Here you can see one of these curved rafters looked like put together.
The framers made four of these for the porch, plus a small one for the overhang.
I was really impressed with their work.
They used construction adhesive and screws to put down ½” CDX plywood- the plywood bends to the curve of the roof.
Next up- we’re going to frame an arched opening above the entrance of this porch. @hausplans

  1. That looks so clean. I just became a License General Contractor, but even tho I became one I still watch this kind of videos because I don’t know it all.

  2. Nice to see how you laid that out on the floor. I used to do large interior arches similarly. Looks great!

  3. New guy always makes me happy 🙂 he looks mean business with his helmet! Safety first!

  4. The little dog kept a good eye on the job!!! Turned out great!!!,🫡🫡🇨🇦🇨🇦

  5. I really wish the US would start doing more of this just that curve changed the look of the whole home.

  6. Flawed design it ties into the house to close to the other over hang . It looks good until it has to be replaced or flashed and the Sofit has to be installed
