What is an acceptable roof pitch?
The short, simple answer is 2:12 has traditionally been considered the absolute minimum acceptable roof slope suitable for asphalt shingles. Asphalt shingles continue to be the most widely installed roof covering option in North America.
What does a 2 12 roof pitch look like?
A 2/12 roof slope means your roof has 2 inches of vertical drop for every 12 inches of horizontal distance. Simply put, it’s a shallow roof. A roof this shallow is likely to be found on a ranch house, a shed dormer or a porch.
What is the proper pitch for a patio roof?
Slope is a ratio of inches per foot, the minimum slope is 1/4″ per foot and the maximum slope is 1″ per foot, the maximum slope is the most the cover can be pitched and the roof panels maintain a proper contact with the hanger and beam.
Can you shingle a 2.5 12 pitch roof?
Yes! The minimum pitch for asphalt shingles is 2/12 inches, and anything less than this is too flat for shingles.
What does a 4/12 roof pitch mean?
A roof that rises 4 inches for every 1 foot or 12 inches of run is said to have a “4 in 12” slope. The slope ratio represents a certain amount of vertical rise for every 12 inches of horizontal run. For example, a “4 in 12” slope can be expressed as the ratio of 4:12. A “6 in 12” slope is expressed as 6:12.

How do I figure the pitch of my roof?
How to Calculate Roof Pitch in Degrees
- First, you need to measure the run of your roof.
- Next, you need to figure out the rise.
- Now, divide the rise by the run.
- Then, divide 1 by your tangent.
- Finally, multiply this result by 180/π and you’ve calculated your roof pitch!
What is the minimum pitch for a corrugated metal roof?
2 inches per 12 inches
Another advantage of the standing seam or corrugated roof panels is the rainwater is channeled to equalize the weight of the water on the roof. It also minimizes large ponding, providing more protection for the roofing material. For these panels, the generally approved slope is at least 2 inches per 12 inches.
What is a 12 6 roof pitch?
Roof pitch (or slope) tells you how many inches the roof rises for every 12 inches in depth. An Example of a roof pitch would be a “6/12 pitch” which means that the roof rises 6 ” for every 12″ inward towards the peak (or ridge).
What is the smallest pitch for shingles?
2/12
Minimum Pitch/Slope of An Asphalt Shingle Roof The minimum requirement is 2/12. The 2/12 number is rise over run or two units of vertical for every 12 units horizontal.
