Emergency and utility numbers in California
For gas odor, downed power lines, or flooding, call 911 or your utility emergency line first — not a contractor. After the immediate hazard is controlled, hire licensed pros for permanent repair.
- 911 — fire, medical, immediate life safety
- Gas odor — leave the building, do not switch lights, call your gas utility emergency number from outside
- Power outage / lines down — utility emergency line; stay away from downed conductors

Verify before you hire in California
Check the licence with the California board
Many states license roofing contractors specifically; individual roofers usually are not licensed. Search the number in the state's public lookup, confirm it is active, and confirm the classification covers your job rather than something adjacent to it.
Have the insurer send the certificate
Ask for general liability and workers' compensation to be sent to you directly by the insurance agent. A PDF forwarded by the contractor proves the document existed once, not that the policy is current.
Get the scope in writing, with exclusions
What is included matters less than what is excluded. Permits, disposal, patching, and code upgrades triggered by the work are the four line items that most often turn into change orders.
Confirm who pulls the permit
Permit thresholds are municipal in California. The licence holder should pull it. If you are asked to pull it as a homeowner on licensed work, you are absorbing their liability.
Never pay the full amount up front
A deposit for materials on a large job is normal. Paying in full before work begins is not, and several states cap what a contractor may take as a deposit.

- RoofingRoof LeakTrace a ceiling stain back to its actual source, which is rarely directly above the visible damage.
- RoofingCeiling Stain SpreadingA spreading ceiling stain means active water — roof, plumbing, or HVAC — not just old discoloration.
- RoofingShingles CurlingCurling shingles signal aging, poor ventilation, or defective batches — plan repair scope before leaks.
- RoofingIce Dams FormingIce dams form when heat melts snow at the ridge and water refreezes at cold eaves.
- RoofingGutter OverflowingOverflowing gutters dump water on fascia and foundation — clogs and pitch are the usual fixes.
- RoofingSiding BucklingBuckled siding comes from trapped moisture, nailing too tight, or heat behind dark siding.
- RoofingAttic Too HotExtreme attic heat cooks shingles and raises cooling bills — ventilation and air sealing matter more than another fan alone.
- SafetyChimney LeaningA leaning chimney is a structural and fall hazard — restrict use until inspected.
