Roofing projects are significant investments that benefit from careful up-front planning. Homeowners who make key decisions before signing a contract end up with better outcomes, fewer change orders, and less stress during construction.
Define Your Scope Before Getting Quotes
A lot of roofing companies will tell you that you need a full replacement when you need a repair. We do an honest assessment first and tell you what the roof actually needs. If it makes more sense to repair than replace, we’ll say so — even if that’s a smaller job for us. Before reaching out to contractors, spend time defining exactly what you want. The more specific your scope, the more accurately contractors can quote — and the less likely you are to face change orders once work begins.
How the Process Works
A typical roofing project follows this sequence:
- Free Assessment — We inspect the roof, check flashing, examine deck condition, and look at all penetrations. We take photos and walk you through findings.
- Written Proposal — You get a detailed scope — materials, underlayment, flashing, and any deck repair needed. Fixed price, no surprises.
- Permit & Install — We pull the permit, remove old roofing, install the new system, and schedule city inspection.
- Final Inspection & Cleanup — City signs off, we do a final check, and clean up thoroughly. Magnetic nail sweep included.
Setting a Realistic Budget
Roofing in the Bay Area comes with a labor premium. The market is tight, workers are experienced, and a proper installation costs more than it does in other parts of the country — but it also lasts longer and passes inspection correctly. Build in a contingency of 10–15 % on older Bay Area homes where wall conditions cannot be fully assessed until work starts.
Typical cost ranges:
- Roof repair (minor): $500–$2,500
- Roof repair (major leak/section): $2,500–$7,000
- Full replacement — comp shingle (1,500 sq ft): $14,000–$22,000
- Full replacement — comp shingle (2,500 sq ft): $20,000–$35,000
- Flat roof (TPO/modified bitumen): $12,000–$28,000
- Tile roof replacement: $25,000–$55,000
Choosing a Contractor
Verify CSLB licence status at CSLB.ca.gov. Ask for a written, itemised scope — not just a total price. Get proof of general liability and workers’ compensation insurance. Ask who your point of contact will be during construction. Ask how the contractor handles unexpected conditions inside walls.
