Roof Pitch Change Detail

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.

Roof pitch change detail.

Change the pitch on an existing sloped roof by removing the old roof and framing. We need to do something where that change happens so the panels can go down and water can come off hit the lower slope and come off the roof. Roof pitch roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. Take off shingles or other roof covering and remove the membrane and sheathing.

The roof plane goes from one pitch to a lower pitch. Use a pry bar to pull loose. This is a fairly common roof detail. A roof pitch is the slant of a roof or how steep a roof s slope is.

See the illustration below. To let the jacks sit plumb on top of the sleepers we angled the level cuts to the 3 1 2 in 12 pitch of the shed roof setting the circular saw to a 16 degree bevel the degree equivalent of a 3 1 2 in 12 pitch. We see this quite frequently in log home roofs with porches for example. Instead it requires professional plans and big structural changes to a house.

While replacing a roof pitch may seem like a simple task it s far from a casual project. We measured from the ridge to the sleepers to get the lengths of the jacks and then cut them and fastened them into place. We re going to do a pitch transition or change. Roof pitch is determined by ridges walls and rafters inside the roof.
