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. Express the slope of a metal roof by a ratio which indicates the pitch of the roof.

You need to consider the slope requirements of each panel to determine this minimum slope. The minimum slope for lapped non soldered seam metal roofs with applied lap sealant shall be one half unit vertical in 12 units horizontal 4 percent slope. This slope works well for sheds that are fairly narrow like 4 to 6 feet but for sheds that are 8 or wider the shed roof becomes unsightly high. The roof pitch measures the steepness of your shed roof and typically takes values from 1 to 12.

The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed. If your roof pitch is greater than 3 your roof is considered pitched. Felt shingle systems can achieve lower slopes down to about 20 degrees. Read more about roof pitch at wikipedia.

Some building codes start at one quarter of an inch per foot or two percent. Asphalt shingles typically have a minimum slope rating of 4 in 12.

This means that for every 12 inches of horizontal distance across the shed the roof will rise 4 inches. However an ideal roof drop per foot should be at least one eighth to one quarter of an inch per foot. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. Roof pitch is used to describe the slope or angle of the roof.

Anything less than one eighth of an inch may pool on the roof. Much depends on what your intended use for the shed actually is. The minimum slope of a roof depends on the roof s profile. The way pitch also known as roof slope is measured is rise over run.

A roof with a slope of 10 degrees 2 12 or less is generally considered a flat roof. Anything with a slope of some kind will cause water to run off the roof. Heavier materials such as slate and clay tiles need a larger.
