All you need is a short refresher on using the right surface area formula.
Roof pitch affects the actual area of the roof.
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.
The average roof is 3 000 square feet or around 30 squares.
Determining the surface area of a roof on a round building is an exercise in simple high school geometry.
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.
This calculation option will also give you a very accurate result.
It affects walkability as well as drainage and roofs in areas of high rain or snowfall tend to have steeper pitches.
Our roof calculator uses base length and base width to find the estimated area.
Area is defined as the expanse or measurement of a given surface and there are a few methods for measuring your roof s area.
The accuracy of.
Depending whether the roof area is measured horizontally.
Take the area of the roof s footprint say it s 5 000 square feet and multiply 5 000 by 1 118.
Roof pitch is a determining factor for cost of the roof as well as the roof area and the type of materials used.
This is expressed in terms of how many inches the roof rises for every foot of horizontal distance.
Place the other end of the level at the peak of the roof and hold it level.
Google maps or other overhead mapping software can also be used to calculate your roof surface area.
The first thing you need to do is download and install google earth pro.
Measure the distance from the surface of the roof to the bottom of the level at the 12 inch mark.
Mark a level 12 inches from one end.
That gives you 5 590 square feet which is the actual area of the surface of the roof.
And for a roof with a slope of 6 12 that number 1 118 is your roof slope multiplier.
As long as you keep in mind that these are only the most basic of guidelines you re going to be okay in your calculations.
Determine the slope of the roof.
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.
Many homes have an asphalt shingle roof but some have wood metal tile and slate which can be more expensive.
Now you re ready to price out the materials.
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.
