Roof Pitch 4 12 Square Foot

On a ladder beside the roof place the level a foot or so up the roof hold it level and measure from the 12 inch mark on the level s bottom straight down to the roof.

Roof pitch 4 12 square foot.

A roof s pitch is determined by how much it rises for every foot it runs. Next multiply the footprint of the roof by the multiplier below for your roof pitch to find the overall roof area. Thus a moderate 6 in 12 roof pitch means the roof rises 6 inches for every 12 horizontal inches it runs. For example a 4 12 pitch roof that is 100 square feet.

A 12 in 12 pitch is a steep 45 degree angle roof. The pitch of the roof is the rise over a 12 inch run. Find the area of a roof. Roof is 6 12 pitch and measures at 2 400 square feet so 2400 x 1 12 2 688 2 88 sqs added for pitch.

The rise is the distance from the top of a stud wall to the peak of the roof. 100 1 054 105 4ft 2. If you have multiple sections of roof find the area of each and add them together to find the total area. Roof pitch area multipliers.

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. Dividing by 12 gives the ratio of inches in rise per distance. Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. 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.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. A square of shingles is the number of shingles needed to cover 100 sq feet of roof area. The table below shows common roof pitches and the equivalent grade degrees and radians for each. 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.

It is often compared to slope but is not exactly the same. Once the area is known divide by the area of a 4 8 sheet to find how much sheathing is needed. If this distance measures 4 inches you have a 4 in 12 pitch. Most roof s have a pitch in the 4 12 to 9 12 range.

8 inches and you have an 8 in 12 pitch. As a rule of thumb there are 3 bundles to a square assuming that you are using three tab strip shingles. However shingles are packaged in a way that they are light enough for the average person to carry around. Get your roof size by using this roof pitch calculator.

For example a standard roof pitch is.
