Example Of Roofing 2 Pitch Roof

Roof pitch defined and explained.
Example of roofing 2 pitch roof. I have read some articles that state this type of metal will work fine and others that implicitly state not to use metal for such a low pitch. Blind valleys simplify framing. For example a 5 12 pitch roof will rise vertically 5 for every 12 it goes back horizontally. The pitch or steepness of a roof is often referred to in terms of the amount of vertical rise over a 12 horizontal run.
In essence a roof pitch chart is provided as a rough guide usually by a roofing company to help you see what the average roof pitches tend to be. Most roof s have a pitch in the 4 12 to 9 12 range. To keep the porch roof framing as simple as possible we installed a structural ridge supported by posts at each end with the common rafters landing on top of the ridge. Roof pitch designations are comprised of two numbers indicating a ratio.
There are smartphone apps available which can be used to sight a roof s pitch from the ground. The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12. If this isn t practical then perform the same measurement on the underside of the roof. Using a pitch measuring tool that i d made we also determined that the exact pitch of the shed roof was 3 1 2 in 12.
Although there is no single standard roof pitch used on all sloped roofs factors such as roofing materials and local climate help to determine the appropriate range of pitches for a given building. Roof pitch is a measurement of a roof s slope expressed as a ratio. A pitch of 2 12 is the minimum pitch for shingles made of asphalt so your roof just barely makes the cut off for one of the most popular roofing material options.
