Pay application software for roofing and waterproofing subcontractors

Billing challenges in roofing & waterproofing
Weather delays
Progress can stall for weeks, then jump. A draft you can return to keeps the period organized.
Material-heavy scope
Membrane and insulation deliveries are significant; stored-material billing needs backup.
Warranty at closeout
Manufacturer warranties are often required for final payment. Track them as required attachments.
Example schedule of values

Roofing & waterproofing billing questions
- How do roofers handle billing when weather stops work?
- You bill the progress actually completed in the period. Saving a draft lets you update it when work resumes before the billing deadline.
- Can I mark a warranty as a required document?
- Yes. Projects can list required attachments, and DrawPrep warns you if one is missing before you submit.
- Can DrawPrep track retainage on this kind of job?
- Yes. You set the retainage rate the contract requires, and each pay application carries it forward and flags a rate that changes between periods so you can confirm it before sending.
