2 1 Pitched Roof

Conventional roofs have the pitch ranging from 4 12 to 9 12 33 3 to 75.

2 1 pitched roof.

The pitch fraction represents a certain amount of vertical rise over the entire span. Or the colon can replace the slash as in 2 12 or 7 12. 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.

The pitch can be expressed numerically as a fraction. They are the easiest ones to construct and they are safe to walk on. 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 table below shows common roof pitches and the equivalent grade degrees and radians for each.

Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. Low pitched roofs aren t able to shed water and snow as easily. Low pitched roofs have the pitch below 4 12 33 3. To see how pitch impacts the look of a garage and changes cost click the design center button on our pole barn kits page.

A roof with one slope historically attached to a taller wall. Pitch is the term used to describe the angle slope or slant of your roof. Roof pitch defined and explained. High pitched roofs often require additional fasteners.

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. They hava a pitch that can be as high as 21 12 175. 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 pitched roof is a roof that slopes downwards typically in two parts at an angle from a central ridge but sometimes in one part from one edge to another.

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 2 12 roof slope is considered low so the roofing materials you would use on a steeper roof may not work. Their fasteners are either concealed or screwed at the top of a ridge which makes them less likely to leak. The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12.

Roof pitch designations are comprised of two numbers indicating a ratio. That means the roofing material you choose needs to protect the materials underneath to prevent water damage and leaks. These are generally difficult in maintenance as they require special materials to avoid leaks. One of the most important aspects of trying to get the roof right though is the pitch.
