A Practical Checklist for Comparing San Diego Roofing Proposals
How to evaluate roofing estimates line by line—from underlayment specs and tear-off depth to workmanship warranties—so you avoid hidden change orders.
Key Homeowner Checklist
- Verify CSLB License Status & C-39 Classification
- Confirm Worker's Compensation Insurance (Not Just General Liability)
- Check Tear-off Depth (1 Layer vs 2 Layer Removal)
- Specify Underlayment Weight (Synthetic Title 24 vs 15lb Felt)
- Verify Flashing Replacement (Step, Valley, Drip Edge & Pipe Boots)
- Confirm Plywood Sheathing Replacement Unit Cost ($/sheet in contract)
- Differentiate Manufacturer Warranty vs Contractor Workmanship Warranty
1. Look Beyond the Bottom-Line Number
A low estimate often omits essential line items like replacing rusty valley metals, installing new drip edges, or providing proper attic ventilation. When comparing quotes, ensure each contractor includes the same scope of tear-off, underlayment type, and disposal fees.
2. Underlayment Matters as Much as the Shingles
In San Diego’s sun-intensive climate, standard organic felt underlayment bakes and degrades over time. Modern synthetic underlayments provide superior tear strength, water resistance, and UV stability during construction.
3. Clarify Wood Repair Pricing Up Front
Contractors cannot see damaged deck boards until old shingles are removed. An honest proposal states the exact per-sheet or per-lineal-foot price for replacing dry-rotted plywood sheathing or rafter tails.
