Roof Length Width

You will need to express this size in terms of square feet.

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. Our roof calculator uses base length and base width to find the estimated area. 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.

Pitch is the incline of the roof represented as the ratio of rise to the span twice the run. 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. It is the length of this portion of the rafter. Length and width standard lengths for corrugated roofing are 8 10 and 12 feet.

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. 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. 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. 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.

Enter the diameter of the roof ridge vent gap 1 3 finally enter the coverage area width of the panels you plan to buy. The width varies greatly depending on the style of roofing.

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. 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. Make sure to document the number of chimneys skylights or other obstructions and include dormers in your measurements.
