Roofing material is estimated by the square which is equal to 100 square feet.
Ways to figure sq ft of roof.
The first step in a free roofing estimate is measuring the roof dimensions.
Roofing contractors estimate projects and materials by the square so it is crucial to find this measurement to accurately estimate the amount of material needed.
Many homes have an asphalt shingle roof but some have wood metal tile and slate which can be more expensive.
Calculate project cost based on price per square foot square yard or square meter.
Divide any irregularly shaped areas of the roof into more manageable triangles and rectangles then calculate square footage for those individual elements and add them to get the total square footage.
To accurately calculate the area of your roof you must first determine its slope or pitch.
Assuming a single story rectangular house with a hip roof that has two foot overhangs on each side of the house we have approximately 13 squares or 1 300 square feet of 2d roof surface area.
If the house has an irregular shape measure each part separately figure the separate areas and add them together.
A square simply refers to a 10 x 10 square of roofing.
Enter measurements in us or metric units.
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.
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.
For example take an area made up of a triangle that s 20 feet high and has a base of 40 feet plus a square that s 40 feet by 40 feet.
Now based on the info provided your home s floor plan is roughly 1 000 sq ft.
1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square.
To find the squares divide the overall roof area by 100 and then round up.
Convert the area to roofing squares.
Calculate square footage square meters square yardage and acres for home or construction project.
How to calculate square footage for rectangular round and bordered areas.
Calculate square feet meters yards and acres for flooring carpet or tiling projects.
Because each 100 square feet of roof is one.
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.
The calculator cannot account for complex shapes based on a measurement of square footage alone.
A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.
This is simply 100 square feet of roof.
