The safest way to compare roofing companies is to make the quotes comparable. A professional-looking proposal means little if one contractor has included tear-off, flashings and deck allowances while another has left them vague.
How do you choose a roofing contractor in British Columbia?
Choose a contractor based on verified business status, WorkSafeBC standing, liability insurance, a clear written scope, material specifications, warranty terms, communication and relevant roofing experience. Price matters, but only after you know the quotes describe substantially the same job.
Why should you verify WorkSafeBC status?
WorkSafeBC specifically advises that a homeowner who hires an independent business can obtain a clearance letter to confirm that the business is registered and in good standing. That is more useful than relying on a logo in a proposal or a verbal assurance.
Ask the contractor for current information and verify it close to the work date. WorkSafeBC's official guidance explains why clearance letters matter.
What insurance should you ask a roofer about?
Ask for a current certificate of commercial general liability insurance and confirm the named business matches the company you are hiring. Do not assume that a vehicle decal, business card or online listing proves coverage.
The policy limit is only one part of the question. Also check that the certificate is current and relevant to the contractor performing the work.
How do you compare roofing quotes properly?
Normalize the scope before comparing totals. For a roof replacement, look for details such as:
- roof areas included and measurement assumptions;
- tear-off, disposal and number of existing layers;
- underlayment and eave/valley protection;
- manufacturer and exact roofing product;
- flashing replacement versus reuse;
- ventilation scope;
- sheathing allowance or unit pricing;
- site protection and cleanup;
- permit responsibility where a permit is required;
- workmanship and manufacturer warranty terms.
Watershed Roofing's roofing process and warranty page provide useful internal reference points when you are comparing a proposed scope.
How should you evaluate a roofing warranty?
Separate the manufacturer material warranty from the contractor workmanship warranty. They cover different risks and can have different registration, maintenance, transfer and exclusion requirements.
- Who is issuing each warranty?
- What exactly is covered?
- How long is the coverage?
- Is it prorated?
- Are labour, disposal or access included?
- Are there maintenance or registration requirements?
- Can it transfer to a new owner?
Do not assume “lifetime” means every cost is covered for the life of the house.
Questions to ask a roofing contractor before you sign
What are roofing contractor red flags?
- pressure to sign immediately without time to review the scope;
- large cash-only deposits without a clear contract;
- refusal to provide current insurance or WorkSafeBC information;
- a proposal that lists only “new roof” with no material or assembly details;
- verbal warranties that are not reflected in writing;
- unclear business identity or mismatch between the proposal, invoice and insured company;
- pricing that is dramatically lower because significant scope items are missing;
- claims that permits, manufacturer instructions or safety requirements never matter.
A low quote can be legitimate. The red flag is not the number itself; it is a number that cannot be explained by a complete scope.
What should be in the roofing contract?
At minimum, the agreement should identify the parties, property, work scope, material specifications, price and payment schedule, approximate timing, change-order process, cleanup responsibilities and warranty terms. Any important promise used to choose the contractor should be written into the agreement rather than left in a sales conversation.
If you are still deciding between repair and replacement, do that scope decision first with the repair-versus-replacement guide. If replacement is the likely path, the 2026 B.C. roof cost guide can help you recognize whether quotes are in a plausible planning range.
Frequently asked questions
Should I always get three roofing quotes?
Three can be useful, but quote count is less important than scope quality. Two detailed, comparable proposals are more useful than five vague prices.
How do I verify a roofer has WorkSafeBC coverage?
Use WorkSafeBC's clearance-letter process to confirm an independent business is registered and in good standing. Verify close to the project date.
Is the cheapest roofing quote usually a bad choice?
No. A lower quote may be efficient and complete. The concern is when the lower total comes from missing tear-off, flashing, underlayment, deck work, disposal or warranty obligations.
Should the roofer pull the permit?
Permit requirements vary by scope and jurisdiction. The contract should clearly state who is responsible for determining and obtaining any required permits.
What is more important: manufacturer certification or local experience?
Both can be relevant. Manufacturer credentials may affect certain warranty options, while local experience helps with exposure, drainage and B.C.-specific roofing conditions. Neither substitutes for verified insurance, safety standing and a clear written scope.
Authoritative reference: WorkSafeBC states that homeowners hiring an independent business may obtain a clearance letter to confirm the business is registered and in good standing. RCABC also publishes consumer roofing guidance for B.C. property owners. This article is practical contractor-selection guidance, not legal advice.
Make the scope clear before the work starts.
If you are comparing roofing proposals, the most useful next step is to confirm that each contractor is pricing substantially the same roof assembly and responsibilities.
