Our calculator will help you estimate the amount of roofing shingles needed for your project plus the cost of materials and accessories.
How to figure out shingles for a roof.
For example you will need to figure out the exact number of shingles required to cover the entire roof area.
The area calculator can be used to calculate the area of a variety of simple shapes that together can comprise the area of the roof.
Next divide your total area by 100 to calculate the number of roofing squares you ll need to buy.
Note that in the last 3 4 years costs of roof shingles and many accessories have gone down by an average of 18 20 currently the us national average for benchmark architectural shingles is around 74 51 square or 25 per bundle.
Finally increase the total by 15 to account for any waste.
Of course there are some measurements which will need to be taken before you are able to calculate the number of roof shingles that you need.
It should have a curved roof.
A mobile home roof should not be flat.
The most common roofing materials used in the united states include shingles.

A square of shingles will be the amount needed to cover an area of 100.
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.
You should use rolled roofing on a flat roof over lap 1 2 the width of the rolled roofing.
Simply enter your roof dimensions and roof type such as gable or hip and approximate roof pitch.
