The Price Per Square Material Tab

Felt:
Enter how much per roll for felt and how many squares per roll. The shaded areas are areas than can be changed.

Other fields:
The fields on this page that are not shaded cannot be changed. How these prices are calculated: Plywood: $14 per sheet x 3.125 = $43.75 per sq. Felt: $12 per roll divided by 2 = $6 per sq etc. Why change ? If you use OSB instead plywood, or if you used 25lb felt, 3 sq per roll etc.
