Roof Length Width

To get results you need to provide roof base dimensions length and width and roof pitch we assume it is identical for all sides.

Roof length width.

The rafter member will be longer. If its pitch is 6 in 12 a pitch multiplier of 1 12 multiplying 1 152 sq ft 107 0 m 2 by 1 12 would give you an overall square footage of 1 290 square feet 120 m 2. Let b the vertical rise in the roof and c the roof length building length gable overhangs. For instance a 38 panel will have an effective coverage width of 36.

One of users asked us to create calculator which will help him estimate hip roof parameters like rafter s lengths roof rise and roof area. Our roof rafter calculator tools are handy for calculating the number of rafters needed rafter length calculator lineal feet of rafter board feed in ridge and sub facia and the total board feet in the roof. If your roof measures 48 feet 15 m x 24 feet 7 3 m multiplying its length by its width would give you a square footage of 1 152 square feet 107 0 m 2. The width is measured simply straight across the top of.

You will need to express this size in terms of square feet. Enter the diameter of the roof ridge vent gap 1 3 finally enter the coverage area width of the panels you plan to buy. 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. 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.

This data allows us to calculate the roof triangle as we know two sides b and c of the three sides of a right triangle the red lines in our photo at above left. Our roof calculator uses base length and base width to find the estimated area. The first step in a free roofing estimate is measuring the roof dimensions. If you plan to have overhang etc.

Length and width standard lengths for corrugated roofing are 8 10 and 12 feet. For example if the roof rises 4 feet and the span is 16 feet twice the run then the pitch is 4 16 or 1 4. Rise and run means that a 6 12 pitch roof has 6 of rise vertical for each foot of run horizontal. First measure the length and width of each surface on the roof then multiply these values to get the square footage of that surface.

The width varies greatly depending on the style of roofing. 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. Make sure to document the number of chimneys skylights or other obstructions and include dormers in your measurements. It is the length of this portion of the rafter.
