Which Way Should Fascia Be Lapped On A Roof Pitch

One picture shows a view from above the pitch transition.

Which way should fascia be lapped on a roof pitch.

This indicates the truss tails extending past the walls. Then we re going to use a scrap of 2x4 to space off the square and strike a line there. At the right of the roof along the gable end we see more drip edge being used to flash the roof gable end fascia trim and roof edge. Rip the tops of the fascia boards to match the slope of your roof.

Making the tops of your fascia boards the same angle as the roof allows you to easily place roofing material over them without creating bumps or ridges. The roof all drains one direction to one gutter so this would be the obvious choice. Set the angle of the circular saw blade to match the slope of your roof and run the saw along the top edge of each fascia board. When you re repairing or installing a new metal roof it s important to know how to properly lap the roofing material.

I m wondering if this transition flashing was installed correctly because it sits high above the ribs on the lower panels i was thinking it should more or less. It s staged payments i don t want to be an arse but i don t see why i should pay for the roof until happy with the result. While you do this determine which direction the metal panels should be aligned. I am pretty sure of the miter angle but the bevel might in fact be 90 degrees minus my number or 56 degrees.

Doing so can prevent water damage to the underlying structure and will help with insulating the building. Using a pitch measuring tool that i d made we also determined that the exact pitch of the shed roof was 3 1 2 in 12. Apply side lap sealant if the pitch of your roof is 2 12 or less. Fortunately with a few safety precautions and some basic information metal roof installation is a very accessible project.

When the panel is laying flat on a surface the side that touches flat is the underlap side. Each panel has an overlap ridge at one end and an underlap ridge at the other end. I prefer to install the gable drip edge under the felt though that detail is less critical than at the lower roof edge or eaves. I got a miter angle of 52 7895 and a bevel angle of 33 5715.

Blind valleys simplify framing to keep the porch roof framing as simple as possible we installed a structural ridge supported by posts at each end with the common rafters landing on top of the ridge. In other words if. It isn t going to leak as it is its aesthetics but obviously they are important when spending a load of money on an extension.
