How To Measure Sq Feet Of Roof

This nominal square footage amount is then multiplied by a factor associated with the roof s pitch.

How to measure sq feet of roof.

Next you will need to use a roofing materials calculator. Measure your house at ground level then add in the roof s overhang for greater accuracy. Convert the area to roofing squares. If its pitch is 6 in 12 a pitch multiplier of 1 12 multiplying 1 152 sq ft 107 0 m 2 by 1 12 would give you an overall square footage of 1 290 square feet 120 m 2.

If your roof measures 48 feet 15 m x 24 feet 7 3 m multiplying its length by its width would give you a square footage of 1 152 square feet 107 0 m 2. Because each 100 square feet of roof is one. Calculate each plane separately. Measure the length and width of every roof plane or surface.

Simply input the surface area of the roof choose from one of the available options and you will get your first roofing estimate. The calculator cannot account for complex shapes based on a measurement of square footage alone. As an example if your overhang is 12 inches you ll add 2 feet to the overall length and 2 feet to the overall width of the house. Check that your footage measurements are within this range so you can start off on the right foot.

Roof pitches in degrees. Include dormers the small outjuttings over attic. In cases where a roof has a complex shape such as in the image to the right measuring the dimensions and areas of each part of the roof to calculate total area will result in a more accurate measurement of area.
