## What is a good roof pitch?

For metal panel roof systems, NRCA recommends slopes of 1/2:12 or more for structural panel systems and 3:12 or more for architectural panel systems. For asphalt shingle, clay and concrete tile, metal shingle, slate and wood shake and shingle roof systems, NRCA recommends slopes of 4:12 or more.

## What is the most common roof pitch?

Conventional slope roofs are most common with residential roofs. This means the slope has a pitch between 4/12 and 9/12 on most homes. Roofs with a pitch exceeding 9/12 are called steep slope roofs.

What does a 4 pitch roof mean?

Roofs require slope for adequate drainage, and even so-called flat roofs must have some incline. A 4/12 roof pitch indicates the roof rises 4 inches in height for every 12 inches, as measured horizontally from the edge of the roof to the centerline.

What angle is a 6 12 pitch?

26.57 degrees
What is A 6/12 Roof Pitch? When you are talking about roof pitches, the first number is the number of inches the roof rises every 12 inches. The angle on a 6/12 roof is 26.57 degrees.

### What does a 7/12 pitch mean?

### What is the minimum roof pitch?

Corrugated roofing is a great material on traditional pitched roofs – but it has severe limitations when the pitch gets below 5 degrees. That is why all roofing manufacturers recommend the 5 degree pitch as the minimum slope and they will not provide any guarantees if it is installed flatter than this.

What roof pitch is 18 degrees?
