What angle roof is safe to walk on?

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.

How steep is too steep for a roof?

Steep slope roofing is defined by roof pitches above 4/12, according to OSHA, the Occupational Safety and Health Administration. As most roofers know, this means that vertical rises of more than 4 inches for every foot going up the slope is the starting point for what's deemed “steep slope” roofing.

How do you walk on a sloped roof?

Rubber-soled boots or shoes are recommended for footwear when walking on a steep roof. A soft rubber sole with a thick tread helps ensure a good grip on the roof's shingles. Roofers recommend wearing rubber-soled footwear even if the roof is dry and stress the importance of keeping the soles clear of mud and debris.

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.

Is a 12 12 roof too steep?

Architecturally described as a "dramatic pitch," the extremely steep roof (ESR) is considered to have a pitch in excess of 12:12, up to a plumb vertical plane. OSHA defines a "steep roof" as any roof with a rise/run ratio over 4:12 (18.43 degrees).

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.

How do roofers not fall?

One of the ways we move around on this type of roof without fear of falling is through use of a toe board. The roofer simply nails a long wooden board—usually a standard 2×4—and uses it to create a walkway. The toe board method is commonly used by most roofing contractors for safety and staging purposes.

What is the best 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 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.

Will my roof support my weight?

Per those guidelines, an ordinary roof on a home needs to hold 20 pounds per square foot at absolute minimum. Depending on your type of roof and what it is used for, it may be required to hold more weight. For example, a flat roof intended to hold a home garden needs to hold 100 pounds per square foot.

Can roofers fall through the roof?

We can all admit that many more roofers fall off of the eaves and rakes than fall through the decking of an old roof. However the Bureau of Labor Statistics notes that the recent number of employees falling through roof openings and failures are dramatically on the rise.

Can a roof be too heavy for House?

Changing to a heavier roof-covering material can cause compression cracking in drywall because the added weight can cause additional settling in the home's structural framing. This condition can actually be dangerous if the roof framing is not adequate to support the additional weight.

Is it safe to put a ladder on a roof?

I don't recommend climbing onto roofs, but if you must, be sure the top of the ladder extends at least 3 feet above the point of contact. When you reach the edge of the roof, grab the top of the rails with both hands, then carefully step around the ladder.

Is a 4/12 roof pitch good for snow load?

At these slopes, snow creeps rather than slides and is easy to manage. On roof slopes between 4/12 and 6/12, rough textured roofing materials work best. They hold the snow in place and keep it from accumulating and then sliding off in large slabs that can be dangerous.

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.
