Every Bid.
Every Phase.
Every Time.
BidShield is the pre-submission bid review platform for commercial roofing estimators. 18 phases, AI scope gap detection, and systematic QA from first plan review to final submission.
What BidShield Covers
The bid QA tool that catches scope gaps and roofing takeoff mistakes before they reach the GC. 18 phases, every discipline, every item.
Mechanical Plan Review
Every curb, equipment support, and dunnage verified against the plan set before takeoff. Quantities reconciled phase-by-phase, not at submission.
Addenda Tracking
Every addendum logged, reviewed for scope impact, and confirmed incorporated before submission. No addendum slips through unreviewed.
Specification Review
Spec sections reviewed for submittal requirements, special inspections, and compliance items that affect your scope and final cost.
