Calculating roof waste

Updated by Heather Jones

You can manually calculate waste on most roofing material items (category RFG) via the Quick Entry panel, but you can also program Xactimate to automatically calculate waste for these items. The former gives you flexibility and control over the waste calculation, and the latter gives you simplicity and easy calculation. 

Manually calculate roof waste 

To manually calculate waste, complete the following: 

  1. Select the RFG item in the Quick Entry panel (Estimate > Estimate Items > Items > Quick Entry).
  2. Select the Item Property Editor icon () to open the table. 
  3. From within the Item Property Editor table, select the Value cell for the Waste row. 
  4. Select the appropriate value from the drop-down list that appears. 
  5. Select OK to save and exit out. 

If the percentage you want is not listed, or you want a more specific percentage, you can change the calculation. For example, if you want to use a 7% waste calculation, change the calculation from SQ to SQ*1.07. See the following video for more details:
