Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.

This free roofing calculator estimates the area of a roof and the amount of materials required to replace or build said roof.
How to estimate roofing materials.
Roofing material is estimated by the square which is equal to 100 square feet.
The average roof is 3 000 square feet or around 30 squares.
Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100.
Most homeowners spend between 1 500 and 3 000 total when hiring a professional and the cost goes up from there for high end materials like slate or other stone tiles which are heavier.
The answer is the number of roofing squares for the roof.
This gives us a 3d roof area of 1 625 sq ft.
For instance if the roof is 1550 square feet then it is 16 squares.
Many homes have an asphalt shingle roof but some have wood metal tile and slate which can be more expensive.

For estimating purposes we also assume that there is a chimney a couple of dormers and two layers of old shingles that need to be torn off and removed before a new roof.
Convert the area to roofing squares.
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.
To find the squares divide the overall roof area by 100 and then round up.
A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.
Keep in mind that the average size of a roof is 1 700 square feet so your total will likely be 10 higher or lower than this figure.
You will need to express this size in terms of square feet.
This is simply 100 square feet of roof.
A square is equal to 100 square feet of the 3 dimensional roof surface.
The average residential roof size in the us is about 1 700 square feet or 17 squares although there are many larger homes with roofs that are twice as large.
