This yields a product called the area which is expressed in square feet or square inches if you are calculating a much smaller space such as a dollhouse.
How do you measure square feet of a roof.
Before you do any roofing work you must calculate the roof s square footage to determine how much material you need.
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.
This nominal square footage amount is then multiplied by a factor associated with the roof s pitch.
Each square is 100 square feet.
Just snap a few photos of the exterior of the house with the hover app and our patented technology will take it from there.
Once the digital property is complete you will receive detailed exterior measurements and an interactive 3d model to help homeowners design their projects.
1 roof square 100 square feet.
If you have a roof section that s 30 feet 9 1 m long and 12 feet 3 7 m high multiplying those dimensions would give you an area of 180 square feet 17 m 2.
If your roof is 5 000 square feet you will have 50 squares.
The length l times the height h of a triangle is twice its area a2.
Make a sketch of your roof before you go out to measure it.
Our patented technology calculates square footage and linear measurements for the roof siding windows trim and more.
For example if you are buying carpet for a room that is 12 feet long and 10 feet wide.
Once you work through the basic triangle we will review a typical roof and how to apply some simple math to calculate how much material you will need for a roof used in our hypothetical example.
Measure and mark the square footage of each triangular section carefully as these tend to differ in size.
To find square feet multiply the length measurement in feet by the width measurement in feet.
Measure your house at ground level then add in the roof s overhang for greater accuracy.
A home s roof is measured in squares.
Roof pitches in.
If you are replacing your entire roof you will need to purchase shingles in 50 squares to sufficiently cover your 5 000 square foot roof.
