What is considered a steep roof?

A roof is considered to be a “steep-slope” roof if the slope is greater than 18 degrees. The installation, repair and maintenance of steep-slope roofs, with their “steeper” needs, require an experienced, full-service roofing company with comprehensive steep-slope capabilities.

Is 7/12 a steep roof?

The roof's pitch is the angle of the roof, usually presented as the inches of vertical “rise” over 12 inches of horizontal “run.” Generally anything above a 7/12 is considered a non-walkable roof and requires some extra equipment and usually some extra cost to the customer.

Is a 10 12 pitch roof steep?

So a roof pitch of 10:12, as seen below, means for every 12 horizontal inches of roof, the roof rises 10 inches. This is a steep slope roof.

What is considered a steep roof slope?

A 9/12 roof pitch (36.37 degrees). is the steepest standard slope. Anything above a 9 over 12 is considered steep slope.

Is an 8 12 roof steep?

As an example, 8/12 means that for every foot, the rooftop rises 8 inches. Slopes around 6/12 are the most common, while anything below 4/12 is typically considered a low pitch.

This is how we do STEEP ROOFS | Walking a 10:12 roof

Is 4/12 A good roof pitch?

4/12 is quite typical. Anything under 3/12 is a low pitch roof. Anything above 6/12 is a steep roof pitch since it becomes harder to walk on the roof. It's pretty easy, to be honest.

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.

Can a roof be too steep?

OSHA defines a "steep roof" as any roof with a rise/run ratio over 4:12 (18.43 degrees). While most standard-pitched residential roofs seldom exceed a 12:12 pitch (45 degrees), the landscape is occasionally marked by a design which harkens back to earlier times, when much greater roof pitches were more common.

What is considered a low slope roof?

A low-slope roof is one that has a slope of less than 3-in-12. This means that for every horizontal foot, the roof level goes up less than 3 inches vertically.

Is a 3/12 roof pitch good?

Any roofs up to 3:12 are generally considered “low slope.” In the residential arena, we see lower slope roofs as part of the home's architectural design. We also sometimes see low slope roofs on just certain areas of a home such as porches.

How can I tell the pitch of my roof?

How to Calculate Roof Pitch in Degrees

1. First, you need to measure the run of your roof. ...
2. Next, you need to figure out the rise. ...
3. Now, divide the rise by the run. ...
4. Then, divide 1 by your tangent.
5. Finally, multiply this result by 180/π and you've calculated your roof pitch!

What does OSHA consider a low slope roof?

OSHA defines a low-slope roof as a roof having a slope of less than or equal to 4 inches of vertical rise for every 12 inches horizontal length (4:12) (1926.500(b)—definitions).

What is the minimum slope for standard built up roofs?

Built-up roofs are required to be a minimum of one- fourth- inch-per-twelve-inch slope. When coal tar pitch is used in a built-up roof, the roof slope is permitted to be reduced to one-eighth inch per foot. The materials in these systems must comply with several ASTM standards.

What is the disadvantages of a steep pitched roof?

Steep-Slope: Cons

This is a challenge or even impossible on a significantly sloped roof. Mounting heavy equipment or large objects on a steep-slope roof can create run-off blockage. The most common problem arising from steep-slope roofs is clogged gutters that result from the run-off debris.

Why should you avoid a 45 degree roof pitch?

You'll also be surprised to know that architects avoid pitches with 45 degrees, even going as far as calling it the "ugly angle" because it doesn't conform to the Golden Ratio.

How do you measure a steep roof?

First, measure 12 inches from one end of the level and make a mark. Then, in the attic, place the end of the level against the bottom of a roof rafter and hold it perfectly level. Now measure vertically from the 12-inch mark on the level straight up to the underside of the rafter, as illustrated.

What roof pitch is 45 degrees?

A 12/12 pitch roof has a pitch angle of 45°.

What is the most attractive roof pitch?

Roofs with pitches that exceed 9/12 are considered steep. Steep roofs tend to be more visible and attractive than flat roofs. Most commercial properties have low-slope roofs with pitches that range from 2/12 to 4/12 inches.

What is a good roof slope?

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's the average slope of a roof?

The most commonly used roof pitches fall in a range between 4/12 and 9/12. Pitches lower than 4/12 have a slight angle, and they are defined as low-slope roofs. Pitches of less than 2/12 are considered flat roofs, even though they may be very slightly angled.

Is a 4/12 pitch roof steep?

Any roof pitch with an angle of 18.43° or a rise-to-run ratio of 4:12 or more qualifies as a steep roof.
