How to find sqft of a roof.

Climb to the top of your roof. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. 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.

It affects walkability as well as drainage and roofs in areas of high rain or snowfall tend to have steeper pitches. Less than 6 inches is a low pitch 6 to 9 inches is a medium pitch and more. 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. Next place your ladder against your house at the gable end.

1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. 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. Roof pitch is a determining factor for cost of the roof as well as the roof area and the type of materials used. For example take an area made up of a triangle that s 20 feet high and has a base of 40 feet plus a square that s 40 feet by 40 feet.

Depending whether the roof area is measured horizontally.
