Roof Pitch of Sunroom with Insulated Aluminum Roof

Calculation of minimum monoslope roof slope requirements for Patio Enclosure with an Insulated Aluminium Roof.

In order to have proper water run-off from the roof a minimum slope is required. This slope is determined by measuring the height (A) where you would like to connect the roof to your home or trailer and the desired height at the opposite side (B).

Then calculate the difference between A-B=(D). Projection is the distance (C) one would walk away from the house or trailer to which the roof is attached.

PROJECTION	MINIMUM SLOPE
(C)	(D)
8'	8"
10'	10"
12'	12"
16'	13"

The projection of the roof has an impact on the thickness requirement of the roof. Please see Specification-Snow Load.

In order to have proper water run-off from the roof a minimum slope is required. This slope is determined by a combination of the height of the screen frames and the projection of the Screen Room, Patio Enclosure. Projection is the distance one would walk away from the house or trailer to which the Screen Room, Patio Enclosure is attached.
