Take the area of the roof s footprint say it s 5 000 square feet and multiply 5 000 by 1 118.
Our roof calculator uses base length and base width to find the estimated area.
The accuracy of.
For multi pitched roofs simply add the areas of all common pitches together by toggling layer visibility from the summed layer identified by the eye symbol at the left of the layers control.
Roofing material is estimated by the square which is equal to 100 square feet.
Many homes have an asphalt shingle roof but some have wood metal tile and slate which can be more expensive.
Measure the distance from the surface of the roof to the bottom of the level at the 12 inch mark.
Determine the slope of the roof.
Determining the surface area of a roof on a round building is an exercise in simple high school geometry.
Place the other end of the level at the peak of the roof and hold it level.
And that s the number you were looking for.
And even flat roofs usually have a little bit of a slope so you might want to use a roof pitch multiplier once you have your area figured out 1.

Calculating your roof surface area building plans offer the easiest way to calculate your roof surface area after all the numbers should all be on there.
It affects walkability as well as drainage and roofs in areas of high rain or snowfall tend to have steeper pitches.
Roof pitch affects the actual area of the roof.

All you need is a short refresher on using the right surface area formula.
