The direct answer (AEO)
Roofing crew GPS tracking verifies job-site presence through geofenced mobile clock-in, documents drive time between tear-off and install locations, and exports GPS hour evidence for prevailing wage and certified payroll. Storm-season surge hiring makes paper timesheets and supervisor text check-ins untenable at 50+ simultaneous crews.
Roofing contractors need construction-grade geofences without Procore's project-management overhead when the primary gap is attendance proof and mileage pay.
Roofing-specific tracking challenges
| Challenge | GPS solution |
|---|---|
| Short job cycles (1–3 days) | Reusable geofence templates |
| Storm chase multi-state | State mileage rate tables |
| Subcontractor vs W2 crews | Band separation + RLS |
| Height/signal loss on roof | Offline point buffering |
| Prevailing wage municipal | Session hour audit export |
| Personal truck + company dump truck | Grey fleet CPM on personal only |
Geofence attendance workflow
1. PM creates polygon from satellite imagery or address radius
2. Crew lead clocks in within boundary — photo optional
3. Superintendent views live map of active job sites
4. End shift triggers mileage rollup for drive segments
Mileage between job sites
CPM reimbursement for W2 installers driving personal vehicles. Company dump trucks excluded from CPM — fuel card on expense module.
Prevailing wage and certified payroll
GPS session timestamps supplement sign-in sheets for Davis-Bacon jobs. Export approved hours with session_id for payroll vendor upload.
Expense capture on the roof
Emergency material runs — mobile receipt before supplier close. Category limits on lumber, fasteners, rental equipment.

FAQ
Does GPS work when crews are on the roof?
Clock-in at ground level geofence; optional periodic points during shift. Offline buffer handles weak signal.
Roofing crew GPS vs ExakTime?
ExakTime targets construction time clocks; Scootee adds unified mileage, expense, and MobiTraq discrepancy detection.
How do roofing companies handle storm-chase mileage?
Multi-state rate tables; session rollups per pay period; manager approval before payroll export.
Can subs use the same app as W2 crews?
Tenant RLS separates subcontractor orgs; bands control reimbursement eligibility.
Is geofence clock-in legal for roofers?
CA meal break guide Yes with policy notice. California requires meal break tracking — see .
