2 12 Slope Roof

For roofs that won t experience heavy snow loads a gable roof can span up to 22 with 2 4 rafters.

2 12 slope roof.

For roofs that will experience heavy snow or wind and will span the same distance use 2 6 rafters. Low pitched roofs have the pitch below 4 12 33 3. They provide excellent weather resistance great value and now more than ever a tremendous range of beautiful designs and color blends. These are generally difficult in maintenance as they require special materials to avoid leaks.

In degrees 10 2 in 12 or 1 in 6 is considered a minimum. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. The exact roof slope in degrees is given by the arctangent. Generally these roofs have a pitch from 1 2 12 to 2 12 from 4 2 to 16 7.

Simply put it s a shallow roof. A 2 12 roof slope means your roof has 2 inches of vertical drop for every 12 inches of horizontal distance. What is the best value price compared to life compared to ease of installation material to go on top of shingle on a 2 12 pitched roof that is also comparatively easy for a handy man homeowner to install considering in order of importance price vs expected life time vs ease of installation. They are the easiest ones to construct and.

Definitions vary on when a roof is considered pitched. The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7. To obtain an accurate roof pitch measurement properly measure the rise and run. That means the roof doesn t shed water as easily as steeper roofs which is why choosing the right type of roofing material is so important.

Conventional roofs have the pitch ranging from 4 12 to 9 12 33 3 to 75. Arctan 3 12 14 0 the primary purpose of pitching a roof is to redirect water and snow. Most roof s have a pitch in the 4 12 to 9 12 range. The table below shows common roof pitches and the equivalent grade degrees and radians for each.

You can use either 2 6 or 2 4 rafters for roofs with a 3 12 pitch or greater but it depends on the overall size of your shed. 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. I ve been reading and reading but haven t found a good answer. Using a tape measure make a pencil mark 12 inches from the end of a carpenter s level.

Thus pitch is typically greater in areas of high rain or snowfall.
