Get More Than One Quote — But Not Too Many
Two or three quotes is the right number for any significant roofing job. One quote gives you no reference point. Four or five means you're spending a lot of time managing surveyors and creates a race to the bottom on price. Two or three gives you a meaningful comparison on scope, material specification and cost.
Be wary of quotes that are dramatically lower than the others. Roofing has clear material and labour costs — a quote that is 40% below market usually means one of three things: cheaper materials than specified, less labour than the job requires, or a deposit taken with no intention of completing the work to standard.
Check NFRC Registration
The National Federation of Roofing Contractors is the main trade body for UK roofing. NFRC members are vetted for competence and insurance, agree to a code of conduct, and have access to a dispute resolution process. Membership isn’t a guarantee of quality, but it's a meaningful baseline check — any established Oxford roofer should be able to demonstrate registration.
NFRC guidance recommends homeowners verify a contractor's membership directly with the trade body rather than relying on a logo displayed on marketing materials. — Source: NFRC guidance
Check membership directly at nfrc.co.uk rather than relying on a logo on a website or van. Logos are trivially copied; the register is not.
Ask for Proof of Insurance
Any roofer working on your property should carry public liability insurance. £2m minimum, £5m is standard for a professional contractor. Ask to see the certificate before work starts — not a verbal assurance, the actual document. If a contractor is uninsured and causes damage to your property or a third party, you may have limited recourse.
Don’t Pay Large Upfront Deposits
A materials deposit of 25–30% is normal for larger jobs where materials need to be ordered specifically. Paying 50% or more upfront to a contractor you haven’t worked with before carries significant risk. A reputable contractor with an established Oxford trading history will not require you to fund the majority of the job before work starts.
Get Everything in Writing
The quote should specify: the scope of work, materials to be used (brand, specification, colour), timeline, payment terms, what happens if additional work is discovered, and the guarantee provided. A verbal agreement is not a quote. If a contractor is reluctant to provide a written quote, walk away.
Check Reviews — But Check Them Properly
Google reviews are the most reliable public review system for Oxford trades. Look for: volume (10+ reviews is meaningful, 100+ is significant), recency (reviews from the last 12 months), specificity (reviews that mention the job type, street area or specific detail are more credible than generic praise), and how the contractor responds to any negative reviews.
Be sceptical of: 5.0/5 ratings with fewer than 10 reviews, reviews that are all posted within a short period, reviews with no text and just a star rating, and review profiles that appear to have been created specifically to review one business.
Oxford-Specific Considerations
For Oxford properties in conservation areas or on listed buildings, check that the contractor has specific experience of conservation area work and understands the material requirements. This is not the place for a general roofing contractor who has never worked with clay plain tiles or Welsh slate matching.
For properties in central Oxford with restricted access, check that the contractor has experience managing scaffold on restricted-width streets and that their quote includes all access costs.
