With a more complex roof such is this one it is highly recommended that you make a basic sketch.
How to figure hip roof square footage.
For parallelogram shaped faces measure one face of each size and multiply the areas of each by 2 to find the total measurement.
A hip roof is a common roof style characterized by 2 pairs of opposing faces sloping downward from a high peak.
Pitch measurement method 2.
The top ridge will be shorter than the one of the gable roof but the four hips will add.
Calculate the square footage area of a hip roof.
The total amount of roofing material you need is 17 300 1 730 19 030 square feet.
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.
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.
8 inches and you have an 8 in 12 pitch.
Now that the basic concept has been covered let s take a look at a more complex roofing system.
Calculate the amount of asphalt or fiberglass shingles needed to cover a hip roof.
If you are trying to undertake this all yourself then you should really be looking for the most effective way of working out things like the hip roof square.
If you re putting down new roofing materials on your home or another building with a hip roof your first step will be to find the exact dimensions of each of the roof s individual faces then use those measurements to calculate its total area in square feet.
To conclude the example if your total roofing area is 17 300 square feet your waste allowance would be 17 300 x 1 1 730 square feet.
The top ridge will be shorter for a hip roof but the 4 hips will add to the amount of.
If this distance measures 4 inches you have a 4 in 12 pitch.
Multiply the square footage of your roof by 1 to get the 10 percent waste allowance.
L 30 feet h 12 feet 30 12 2 180 square feet.
The square footage of a hip roof area is identical to the square footage of a gable roof of the same size.
For many people being able to get the right kind of hip roof calculator is very important as knowing how to measure a hip roof is going to be vital to making sure that it turns out well.
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.
The only difference in this calculation to the one for a gable roof area is the amount of the ridge.
The calculator cannot account for complex shapes based on a measurement of square footage alone.
A hip roof s square footage is equal to that of a gable roof with the same dimensions.
Don t measure each face if the hip roof is square.
