Roof area reroof 100 sq ft.
1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square.
If you are replacing your current roof add 125 to 500 per roofing square for old roof removal.
To do that simply multiply drainage area calculated earlier by roof pitch factor and rainfall intensity.
When calculating roofing costs per square asphalt shingles run from 350 and 500 per square metal or tin roofs costs 600 to 1 200 per square and concrete or clay costs between 1 200 and 1 800 per square.
The national average cost to replace or install a roof is 6 771 and prices typically range from 4 700 to 9 200.
Or 450 per square to replace an asphalt shingle roof on a typical single family house.
A square of shingles is the number of shingles needed to cover 100 sq feet of roof area.
Roofing cost per square foot.
However shingles are packaged in a way that they are light enough for the average person to carry around.
Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.
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.
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.
To accurately calculate the area of your roof you must first determine its slope or pitch.
This is simply 100 square feet of roof.
After you have calculated the square footage use following calculations.
For instance if the roof is 1550 square feet then it is 16 squares.
Thus at the mid point of the above price range you can expect to pay about 4 50 per sq.
Roofing material is estimated by the square which is equal to 100 square feet.
To find the squares divide the overall roof area by 100 and then round up.
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.
As a rule of thumb there are 3 bundles to a square assuming that you are using three tab strip shingles.
The average roof is 3 000 square feet or around 30 squares.
Some customers have also reported paying as much as 22 000 for a roof replacement and some companies charge as much as 25 000 for a new roof.
Using the aggregate area of these simple shapes can yield a more accurate roof area to be used with the roofing.
A square simply refers to a 10 x 10 square of roofing.
Many homes have an asphalt shingle roof but some have wood metal tile and slate which can be more expensive.
