The result of joining two or more hip roof sections together forming a t or l shape for the simplest forms or any number of more complex shapes. Using these angle definitions i will derive formulas for the sheathing θ s and hip pitch angle θ h given the common pitch angle which i call the roof pitch θ r and plan angle θ p.

Enter the extension wall length into wall length and double the extension wall width then minus ridge thickness into the wall width entries.
