The lower slope length is measured from outside wall to the start of the upper sloped roof section.
How do you get square footage of a roof.
For example if your roof s pitch is 4 in 12 you would divide 4 by 12.
The calculator cannot account for complex shapes based on a measurement of square footage alone.
Apply the square footage formula the next step in how to calculate square footage is to plug your measurements into the square footage formula.
You can even embed this tool on a website that you own.
Multiply the length by the width to arrive at.
Gambrel roof square footage calculator calculate the square footage of a gambrel style roof using imperial measurements.
As a rule of thumb there are 3 bundles to a square assuming that you are using three tab strip shingles.
Using this tool will be very helpful for you in finding out the acreage or the tract of land of your property.
A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.
A square of shingles is the number of shingles needed to cover 100 sq feet of roof area.
L x w a in square feet to find square feet multiply the length measurement in feet by the width measurement in feet.
However shingles are packaged in a way that they are light enough for the average person to carry around.
To accurately calculate the area of your roof you must first determine its slope or pitch.
Include dormers the small outjuttings over attic windows.
Measure the ground dimensions of the house using a tape measure and write down these dimensions.
It will also give you the square footage of your roof and any other areas that you re wanting to estimate.
Multiply the length and width of each square or rectangle shaped plane.
Calculate each plane separately.
It will also give you the perimeter of the shape of the roof.
Because each 100 square feet of roof is one roofing square divide.
How do you calculate square footage for a roof.
Convert the area to roofing squares.
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.
Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.
Calculating the area estimated if you don t want to do a lot of measuring you can use your pitch calculation to get an estimated square footage of your roof.
