You will need to express this size in terms of square feet.
How to estimate roofing sheets.
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.
Area is defined as the expanse or measurement of a given surface and there are a few methods for measuring your roof s area.
Once you have the area you can divide by the area of a sheet of plywood to find the number of sheets needed.
Then add 10 to the number to account for waste.
The first step in a free roofing estimate is measuring the roof dimensions.
Our roof calculator uses base length and base width to find the estimated area.
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.
Calculate carport or structure total m area.
So dividing the area of the roof by 32 will give you the number of sheets needed.
A 4 8 sheet of plywood is 32 ft 2.
The base width is the distance from one corner of your roof to the other at its base on the short side of your house.
Multiply length by breadth.
For instance a 38 panel will have an effective coverage width of 36.
We plan to enable the use of fractions at a later time.
In order to be able to calculate the number of roofing sheets required for your building you ll need to ask your contractor or engineer the actual size of his intended roofing sheet.
Take roof sheet measurements 2.
For example if your roof is 1 500 ft 2 then it will take 47 sheets of plywood to sheath it.
Enter the diameter of the roof ridge vent gap 1 3 finally enter the coverage area width of the panels you plan to buy.
Using the aggregate area of these simple shapes can yield a more accurate roof area to be used with the roofing material calculator.
Now find out the length and breadth of each roofing sheet and also.
The metal roof length calculator calculates the distance from peak to trim so add the length you want the roof metal to extend beyond the eave trim.
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.
