Important Notes
- The weights listed are for the materials themselves and do not include the supporting structure (trusses/rafters).
- To calculate the total dead load of the roof assembly, the weight of the trusses or rafters must be added to the sum of the selected roofing, sheathing, and underlayment materials.
- The conversion factor between the two units is: .
