Roof pitch is the measurement of roof steepness.
Minimum workshop roof slope.
The minimum roof slope for metal roofs is dependent upon the roof profile.
Clay and concrete tile requires a minimum roof pitch of 2 1 2 12 or greater.
The following table provides the minimum required allowable roof slope for each type of roofing material mentioned in the code.
The short simple answer is 2 12 has traditionally been considered the absolute minimum acceptable roof slope suitable for asphalt shingles.
A ratio is the most common way of expressing roof pitch or roof slope but degrees are also possible.
Minimum pitch for metal roof.
The profile is the shape taken by the sheets when you bend them to form panels.
The minimum roof slope allowed by code for any type of roof is in 12 applicable only to coal tar pitch roof systems.
Let us recap on the minimum roof pitch required for each type of roofing material.
An example for a steep sloped roof is 8 12.
To get the minimum pitch for a metal roof the vertical rise per foot is divided by the horizontal slope.
The way pitch also known as roof slope is measured is rise over run.
Asphalt shingles continue to be the most widely installed roof covering option in north america.
Metal roof shingles require a minimum roof pitch of 3 12 or greater.
They provide excellent weather resistance great value and now more than ever a tremendous range of beautiful designs and color blends.
To put it in perspective the angle of this slope would be around 30 degrees.
The minimum pitch for a roof is 1 4 12 which translates to 1 4 inch rise to 12 inches of run.
Express the slope of a metal roof by a ratio which indicates the pitch of the roof.
The values given here.
This means that the rise of the slope goes up or down 8 inches for every 12 inches.

Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run.
Asphalt shingles require a minimum roof pitch of 2 12 or greater.
You need to consider the slope requirements of each panel to determine this minimum slope.
The slope of a roof or pitch is determined by how many inches the roof rises over 1 foot or 12 inches.
With regards to metal roofing the profile refers to the shape adopted by the metal sheets when they are bent to form the panels.
So if your roof rises 4 inches for every 12 inches of horizontal length then the pitch of your roof is expressed as 4 12.
