Change the pitch on an existing sloped roof by removing the old roof and framing.

We see this quite frequently in log home roofs with porches for example. Roof pitch is determined by ridges walls and rafters inside the roof. Take off shingles or other roof covering and remove the membrane and sheathing. The roof plane goes from one pitch to a lower pitch.

You ll have a steeper part of your roof turning into a lower slope so there s a steeper pitch up top and a lower pitch on the bottom. A roof pitch transition is a line in the roof plane that changes pitch. Instead it requires professional plans and big structural changes to a house. We measured from the ridge to the sleepers to get the lengths of the jacks and then cut them and fastened them into place.
