How it Calculates
The calculator multiplies the length and width to get the base roof area. It then adjusts this area based on the pitch of the roof using the formula:
Total Area = length * width * (1 + (pitch * pitch / 100)).
After calculating the base area, it adds the waste percentage to get the total roof area:
Total Roof Area = base area * (1 + waste percentage / 100).
Finally, it multiplies the total roof area by the price per square foot to get the total cost:
Total Cost = total roof area * price per square foot.
Limitations
This calculator assumes a rectangular roof shape and does not account for more complex shapes. The pitch is considered as a simple rise/run ratio. Make sure all input values are correct numbers; the script does not handle invalid inputs and will alert the user to correct them.
