2 1 pitched roof.

The pitch of a roof is its vertical rise divided by its horizontal span and is a measure of its steepness. Generally these roofs have a pitch from 1 2 12 to 2 12 from 4 2 to 16 7. Roof pitch designations are comprised of two numbers indicating a ratio. They hava a pitch that can be as high as 21 12 175.

But the taller profiles like standing seam and pbr shown below can be installed on roofs with as low as 1 4 or 1 2 in 12 pitch. A roof with one slope historically attached to a taller wall. A pitch over 9 12 is considered a steep slope roof between 2 12 and 4 12 is considered a low slope roof and less than 2 12 is considered a flat roof. The pitch fraction represents a certain amount of vertical rise over the entire span.

Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. Roof pitch defined and explained. High pitched roofs often require additional fasteners. Mono pitched roofs pitched here means a roof plane rather than a slope and implies it is not a flat roof mono pitched roof shed skillion lean to roof 2.

Most roof s have a pitch in the 4 12 to 9 12 range. Their fasteners are either concealed or screwed at the top of a ridge which makes them less likely to leak. These are generally difficult in maintenance as they require special materials to avoid leaks. Understanding a roof s pitching can be quite tough if you are just getting started and working with a roofer can leave you a little bit unsure about what is being suggested with regard to the job there s so much to learn that it can become a bit baffling.

Low pitched roofs have the pitch below 4 12 33 3. The pitch can be expressed numerically as a fraction. One of the most important aspects of trying to get the roof right though is the pitch. They are the easiest ones to construct and they are safe to walk on.

Or the colon can replace the slash as in 2 12 or 7 12. That means the roofing material you choose needs to protect the materials underneath to prevent water damage and leaks. Conventional roofs have the pitch ranging from 4 12 to 9 12 33 3 to 75. Low pitched roofs aren t able to shed water and snow as easily.

For example given a roof with a rise of 4 feet and a span of 24 feet the pitch is 1 to 6 pitch which can be expressed as the fraction of 1 6. A 12 to 24 pitch is expressed as 1 2. A 2 12 roof slope is considered low so the roofing materials you would use on a steeper roof may not work. Pitch is the term used to describe the angle slope or slant of your roof.
