Which Way Should Fascia Be Lapped On A Roof Pitch

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.

Which way should fascia be lapped on a roof pitch. Doing so can prevent water damage to the underlying structure and will help with insulating the building. 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. 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. To figure out for the sheathing snap line swing the square over to the pitch of the roof in this case it is a six pitch and strike a line right there.

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. 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. 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. While you do this determine which direction the metal panels should be aligned.

In other words if. I am pretty sure of the miter angle but the bevel might in fact be 90 degrees minus my number or 56 degrees. I used my cad program to draw a squarecut fascia tracking a 10 12 dormer roof and dying onto a 7 12 main roof. 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. I got a miter angle of 52 7895 and a bevel angle of 33 5715. The other shows a view underneath the pitch transition strip flashing taken from the lower flatter pitch of roof. Then we re going to use a scrap of 2x4 to space off the square and strike a line there.

When you re repairing or installing a new metal roof it s important to know how to properly lap the roofing material. When the panel is laying flat on a surface the side that touches flat is the underlap side. Rip the tops of the fascia boards to match the slope of your roof. This indicates the truss tails extending past the walls.

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. 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. The roof all drains one direction to one gutter so this would be the obvious choice.
