How to calculate square footage for rectangular round and bordered areas.

How to determine roof square footage.

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. Calculate square footage for a roof by measuring and by performing some basic math equations. Before you do any roofing work you must calculate the roof s square footage to determine how much material you need. 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 is flat or has no more than a 3 in 12 pitch you can calculate its total square footage by simply multiplying the length by the width. Calculate square feet meters yards and acres for flooring carpet or tiling projects. With the area measurement you can learn the approximate cost of a new roof. Shingles and other roofing materials such as underlayment are typically measured in squares that are 10 feet long and 10 feet wide with each square measuring 100 square feet.

How to calculate the roof area using the building square footage the pitch of the roof. You will need to express this size in terms of square feet. Calculate square footage square meters square yardage and acres for home or construction project. Calculate project cost based on price per square foot square yard or square meter.

Use this information if. Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy. The calculator cannot account for complex shapes based on a measurement of square footage alone. Keep in mind that the average size of a roof is 1 700 square feet so your total will likely be 10 higher or lower than this figure.

So you re thinking of reroofing the house yourself and want an estimate for how much roofing material you. To calculate the size of the roof you need to measure the size of the roof as if it were flat account for roof pitch calculate square footage and finally determine how many squares of material are required for the roof the calculator above can handle all of this simply enter the length width and pitch and it will determine the size of the roof in squares. Get the square footage of roof and divide it by 100 and it will give the number of squares you need and for every decimal number over 3 buy a bundle to achieve the amount of material. Enter measurements in us or metric units.
