I am about to replace my house’s in poor shape beveled 1×9 cedar siding (with 5/4×8 rabbeted and beveled cedar), so it looks like a good time to add the gable-end roof overhangs we’ve always wanted. I plan to construct 12 inch wide ladders out of 2X4’s and bolt them to the house-side flush 2×10 roof rafter, and support with exposed upside-down right angle triangles made of cedar 2×4’s. The roof has a 5/12 pitch and the longest straight run to be extended is over 24 feet.
The questions: (1) Is a 45 degree angle adequate for the support triangles? and (2) how far apart can the supports be spaced?
