Figure square feet of roof.
To measure this roof we used a 25 foot tape measure and sketched the roof out.
Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100.
How to calculate your roof square footage first measure the length and width of each surface on the roof then multiply these values to get the square footage of that surface.
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.
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.
Make sure to document the number of chimneys skylights or other obstructions and include dormers in your measurements.
Convert the area to roofing squares.
Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy.
How to calculate square footage for rectangular round and bordered areas.
Measuring a roof is pretty simple if you know what you re doing.
Calculate project cost based on price per square foot square yard or square meter.
The answer is the number of roofing squares for the roof.
You want to.
Before you do any roofing work you must calculate the roof s square footage to determine how much material you need.
Or roughly 50 squares.
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.
Calculate square footage square meters square yardage and acres for home or construction project.
1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square.
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.
The calculator cannot account for complex shapes based on a measurement of square footage alone.
96 x 18 1728 and 18 x 18 2 162 for a total of 1890 square feet.
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.
Now take all sections and add them up.
