Roof Pitch 4 12 Square Foot

Multiply the length of the roof in feet by the width of the roof in feet to find the area of the roof in square feet.

Roof pitch 4 12 square foot.

Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. Get your roof size by using this roof pitch calculator. A 12 in 12 pitch is a steep 45 degree angle roof. Dividing by 12 gives the ratio of inches in rise per distance.

Roof pitch area multipliers. If you have multiple sections of roof find the area of each and add them together to find the total area. A roof s pitch is determined by how much it rises for every foot it runs. Thus a moderate 6 in 12 roof pitch means the roof rises 6 inches for every 12 horizontal inches it runs.

However shingles are packaged in a way that they are light enough for the average person to carry around. It is often compared to slope but is not exactly the same. 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 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.

Next multiply the footprint of the roof by the multiplier below for your roof pitch to find the overall roof area. Most roof s have a pitch in the 4 12 to 9 12 range. For example a standard roof pitch is. 8 inches and you have an 8 in 12 pitch.

The table below shows common roof pitches and the equivalent grade degrees and radians for each. In the united states a run of 12 inches 1 foot is used and pitch is measured as the rise of the roof over 12 inches. As a rule of thumb there are 3 bundles to a square assuming that you are using three tab strip shingles. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.

If this distance measures 4 inches you have a 4 in 12 pitch. Use our roof pitch calculator to find the pitch of your roof. Find the area of a roof. For example a 4 12 pitch roof that is 100 square feet.

A square of shingles is the number of shingles needed to cover 100 sq feet of roof area. The rise is the distance from the top of a stud wall to the peak of the roof. Roof pitch is given as the number of inches in height change over the distance of one foot. Once the area is known divide by the area of a 4 8 sheet to find how much sheathing is needed.

The pitch of the roof is the rise over a 12 inch run.
