How do you get square footage of a roof.
Your roof is without a doubt one of the most important elements of your home.
Finally calculate your roof s total square footage by simply adding the square footage of each of the planes together.
Before you do any roofing work you must calculate the roof s square footage to determine how much material you need.
Therefore you ll need 141 sq.
The square footage of a hip roof area is identical to the square footage of a gable roof of the same size.
So continuing our example if you ve got a two story house with a total square footage of 2 700 square feet with each floor having 1 350 square feet multiply 1 350 by 1 0541 to get 1 423 square.
For example this shed roof has one roof plane.
A square simply refers to a 10 x 10 square of roofing.
The only difference in this calculation to the one for a gable roof area is the amount of the ridge.
This is simply 100 square feet of roof.
4 adjust for waste once you ve found the quantity of material you need to complete your project adjust the amount for waste.
Things you will need steel tape measure.
How to calculate square footage for rectangular round and bordered areas.
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.
Roofing contractors estimate projects and materials by the square so it is crucial to find this measurement to accurately estimate the amount of material needed.
To do this measure the length and width of each plane on the roof including dormers.
This nominal square footage amount is then multiplied by a factor associated with the roof s pitch.
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.
Calculate square footage square meters square yardage and acres for home or construction project.
Multiply the number of roofing squares for a medium pitch roof by 1 12 to 1 25 or by 1 3 to 1 42 for a high pitch roof to get the square roof area.
Calculate project cost based on price per square foot square yard or square meter.
To find the squares divide the overall roof area by 100 and then round up.
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.
Then add the three values together to get the total square footage you ll need.
Roof pitches in degrees.
The top ridge will be shorter than the one of the gable roof but the four hips will add to the ridge length.
