How to build a 6 12 pitch roof for house.

The way pitch also known as roof slope is measured is rise over run. Cut each of the house ends while continuing installing the rafters so that they fit the top of the rafter beam perfectly. I also used quality class number 6. A pitch of 3 12 means a rise of 3 for every 12 of run so 3 x 14 42.

Use 1 2 plywood for the gussets. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. A ratio is the most common way of expressing roof pitch or roof slope but degrees are also possible. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.

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. A framing square is traditionally used for laying out the roof and determining pitch. A 12 in 12 pitch is a steep 45 degree angle roof. Pitch ratios range from 2 12 to 12 12.

So if your roof rises 4 inches for every 12 inches of horizontal length then the pitch of your roof is expressed as 4 12. Pitch is the amount of angle or slope the roof has.

The first step of the project is to build the rafters for the gable roof of the 6 12 shed. See the image below for more explanation on rise run and pitch. The pitch of a roof is the rise the vertical angle of the roof over the run the horizontal measurement. Assuming a gable roof 1 2 of 28 14.
