Put the flashing on the meeting point of both roofs.Prepare a flashing material in the width of approximately 12-inch.Pick the section where two edges will cross. Measure the length of the joined area.Prepare the area by identifying where the two different-pitched roofs will meet.Finish by nailing OSB sheathing, metal flashing, metal drip edge, and overlap the new shingles between two joined roofs.īelow are the steps on how to join two roofs together if they have different pitch:.Brace trusses on both of the roofs upright, and nail them to complete the roof framing.Then cut jack rafters to connect the ridge board and valley board.

Shed roof is similar to a flat roof but has more pitch, it is frequently used for additions or with other roof styles. Most flat roofs are not really 100% flat, they are low-sloped roofs that appear flat, but have a little bit of a slope to allow for the run-off water. This allows more room on the inside and in most cases creates an extra space. The bottom part of the roof slope is steeper so that the pitch of the roof barely starts. The mansard roof actually features two slopes within one on each side. It is a French design and is more difficult to build than the hip or gable roof.
