Step 1 — Inspection & Written Estimate
A proper estimate should specify:
- Tear-off vs overlay (and number of layers)
- Underlayment and ice/water details (if used)
- Flashing scope (chimney, wall, valleys)
- Ventilation plan (ridge + intake)
- Warranty terms
Step 2 — Scheduling & Material Ordering
What affects lead time:
- Seasonality (post-storm demand spikes)
- Specialty materials (metal profiles/colors)
- HOA requirements (if applicable)
Step 3 — Permits & Code Requirements
Many reroofs require permits depending on jurisdiction and scope. A professional contractor should handle permitting and coordinate inspections when required.
Step 4 — Installation Day(s)
Typical sequence:
- Property protection (landscaping, tarps)
- Tear-off and deck inspection (OSB/plywood condition)
- Deck repairs (if needed)
- Underlayment + drip edge
- Shingle/metal install
- Flashing and penetrations
- Ridge cap / ridge vent
- Cleanup with magnet sweep
Step 5 — Final Walkthrough + Documentation
You should receive:
