Pitch is the slope or angle from the wall plate to the roofing system ridge line. Pitch can vary a good deal, from a shallow slope up to a very high pitch. Pitch for a gable roofing system, the most common, is usually 1/4 or 1/3; which amounts to 1/4 or 1/3 the overall span of the building, not counting any overhang.

For lower pitches, a built-up or constant roll roofing need to be applied to keep the roofing waterproof.

This short article will talk about a gable roof, without valleys or dormers, because it's the most typical and the easiest for a newbie home builder to tackle.
There are 3 basic cuts used in creating the rafter; the plumb cut at the top of the rafter where it fits against the ridge plate; the tail cut that creates the outside edge of the building eaves; and the bird's mouth, which places the rafter on the top of the wall plate.
