I would like some opinions on attaching a shed type roof to my house when covering my deck. my house is a story & 1/2 so where it attaches is on the back wall of the house. 1 end will stop at a 90 deg corner (room of house that pops out approx 4 feet) the roof will be shingles with timberlines and have about a 4/12 pitch. from what i have found so far, at least I need to cut through the siding just above where the shingles/sheeting will be and install flashing along the length of the roof. Then down the side where it meets the wall. Seems as it will be tricky in the corner of the 2 walls and at the end of the roof. do you just try to overlap it in the corners and caulk it there and also at the end of the roof where the roof sops and the siding(wall of house) continues? sorry for lengthy question...any advice would be appreciated. thanks.
