The best part of a roofing calculator is that it offers a free insight into the total cost of the replacement roof project on a sq ft basis.
How do i get estimate of sq ft of roof.
1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square.
As you begin to calculate various costs you will see that the cost is a result of the interplay of many different variables including roof area in terms of footage measurement of any roof extras like chimneys or skylights and the dimensions of.
Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100.
For example if a triangle shaped roof plane measures 60 feet along the base and is 30 feet high we have 60 x 30 1 800 feet divided by 2 900 square feet for the triangle shaped plane.
The top ridge will be shorter than the one of the gable roof but the four hips will add.
Step 4 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.
For instance if the roof is 1550 square feet then it is 16 squares.
A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.
To accurately calculate the area of your roof you must first determine its slope or pitch.
To find the squares divide the overall roof area by 100 and then round up.
The square footage of a hip roof area is identical to the square footage of a gable roof of the same size.
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.
Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.
To estimate roofing materials start by finding the total square footage of the roof and divide the number by 100 to determine the number of squares in the roof.
How to estimate roofing materials.
This free roofing calculator estimates the area of a roof and the amount of materials required to replace or build said roof.
Roofing materials are bundled in squares that contain enough shingles to cover 100 square feet 9 3 m 2.
Calculate the square footage area of a hip roof.
Dividing 1 290 sq ft 120 m 2 by 100 for example will tell you that you need to order at least 13 squares to get the job done.
Explore a number of housing related calculators as well as hundreds of other calculators covering topics such as finance math health fitness and more.
The answer is the number of roofing squares for the roof.
Divide your estimated square footage by 100 to estimate your materials.
The only difference in this calculation to the one for a gable roof area is the amount of the ridge.
This is simply 100 square feet of roof.
