TL;DR — what should you check first?
Choose a Los Angeles roofing company by verifying its current CSLB license and scope, bond and insurance, then comparing written condition reports and itemized proposals. Confirm permit responsibility, the complete roofing assembly, address-specific fire and energy requirements, and a lawful payment schedule. The best fit explains repair versus replacement before asking you to commit.

Which license should a roofing company hold?
Start with the California Contractors State License Board record, not a license number printed on a truck. Confirm active status, the legal business name, classifications, bond and workers’ compensation information. C-39 is the roofing specialty classification. A B – General Building license has scope conditions; it is not blanket authority for every standalone specialty trade. Ask how the proposed roofing contract fits the license and whether an appropriately licensed specialty contractor is involved.
If a proposal also includes structural repairs or other trades, identify who takes responsibility for each part. The contract name should match the licensed entity, and the permit should accurately identify the contractor performing the work. CSLB can clarify classification questions; a homeowner should not have to infer the arrangement from an advertisement.
What should a written roof condition report explain?
Ask for dated photographs and a description of the accessible roof, flashing, penetrations, drainage and visible deck concerns. A leak can originate away from the ceiling stain. The report should distinguish a localized flashing repair from widespread material failure, worn tile underlayment or a replacement scope. It should also state areas that could not be inspected rather than presenting inaccessible conditions as known facts.
A quote should identify tear-off versus an overlay where allowed, underlayment, flashings, roof covering, ventilation, disposal and protection. Concealed sheathing repairs need a stated pricing method or allowance and an approval process. Tile reuse, skylights, gutters and interior leak repairs should be included or excluded explicitly. Compare the same assembly and repair assumptions across bids, not just the visible shingle brand.
How do permits, fire zones and Title 24 affect the choice?
Verify the permitting authority for the address: LADBS for City of Los Angeles properties, or the relevant independent city or county agency. Ask the contractor to identify the required permit, inspections and final closeout. Do not accept “roofing never needs a permit” as a substitute for confirmation of the actual scope with the building department.
CAL FIRE and the Office of the State Fire Marshal publish Fire Hazard Severity Zone information. A hazard map is not a site-specific prediction of loss. Check the parcel designation and local requirements, including the specified Class A roof assembly and any applicable wildfire-resistant details. The complete tested assembly matters; a product description alone does not establish that the installed system meets the requirement.
Title 24 Energy Code cool-roof requirements depend on the project, roof characteristics, climate zone and applicable compliance provisions. Ask which code edition and compliance path apply, and request product documentation where required. Do not assume every Los Angeles roof must use the same color or that a marketing label proves compliance. The enforcing building agency is the authority for your project.
For the plain-language version, our Title 24 cool-roof guide lists the reflectance values and exceptions for Los Angeles re-roofs, and our roof replacement cost guide shows the published planning ranges and the drivers behind them.
How should insurance, certification and payments be checked?
A contractor’s bond and insurance are different protections. Review the current CSLB bond record, ask for a general liability certificate, and verify workers’ compensation coverage and any applicable record requirements. Confirm coverage and validity with the issuer where necessary. A photograph of an old certificate is not the same as current evidence.
If manufacturer certification is claimed, verify the installer directly with that manufacturer and ask which warranty, registration and installation requirements follow from it. Certification is not a replacement for licensing, permits or insurance, and it should not be assumed to apply to every product a company installs. Separate manufacturer product coverage from contractor workmanship terms.
For a covered California home-improvement contract, the down payment cannot exceed $1,000 or 10% of the contract price, whichever is less. Progress payments should not exceed the value of completed work or delivered materials. Confirm the requirements and any applicable exceptions with CSLB for your contract.
How can you compare proposals side by side?
| Criterion | Evidence to request from each contractor |
|---|---|
| License and scope | Active CSLB record, matching entity and appropriate classification/contract arrangement |
| Bond and insurance | Current bond status and verifiable liability and workers’ compensation information |
| Roof diagnosis | Written condition report, photographs, limits of access and repair/replacement reasoning |
| Complete assembly | Specified covering, underlayment, flashing, ventilation and concealed-repair method |
| Permit and code | Correct agency, inspection responsibility and address-specific fire/energy documentation |
| Certification and warranty | Manufacturer verification where claimed; actual written coverage and exclusions |
| Payments and closeout | Lawful deposit, work-based milestones, change approvals and final permit documentation |
Which questions should you ask before signing?
- Why is repair, relay or replacement the recommended scope?
- Which contractor and license will appear on the contract and permit?
- How are hidden sheathing repairs priced and approved?
- What fire and energy requirements apply to this address?
- Who protects the home if weather interrupts tear-off?
- What triggers each payment, and what documents are provided at closeout?
Which red flags should make you pause?
- A roof price without an assessment or written scope
- An inactive license or a business name that does not match
- A blanket claim that permits or energy rules never apply
- Unverifiable manufacturer badges or unspecified warranty promises
- A large upfront payment or payments ahead of completed work
- Pressure to sign before reviewing exclusions and alternatives
