The cheapest roofing quote? The lowest headline price is not always the lowest final bill. Compare the full proposal before choosing.
Check the total payable. Make sure every quote states its VAT treatment. A price excluding VAT is not directly comparable with one including VAT.
Check what is included. Compare materials, scaffold, waste, insulation and ventilation. A blank is an unknown. It is not an inclusion.
Control the extras. Ask how hidden defects will be photographed, priced and approved. Get missing details in writing before accepting.
Compare like for like. Use our roofing quote comparison tool at northeastroofanswers.co.uk. Send J&L Welch your roof details for a written quotation. General guidance; property-specific assessment needed.
Normal reasons for a genuine difference
- Different covering products and guarantees
- Different scaffold and protection requirements
- Full renewal versus an overlay or partial repair
- Different insulation and ventilation solutions
- Allowance for leadwork, timber and access
- Company overhead, competence and aftercare
Create a like-for-like comparison
Put the quotations side by side and mark every inclusion, exclusion and provisional allowance. Ask each contractor to price the same missing items before deciding. The best value is the lowest credible whole-job cost, not the lowest first number.
Questions that expose risk quickly
- Which named materials will be installed?
- Is scaffold and VAT included?
- Who handles Building Regulations compliance?
- How are hidden defects approved and charged?
- Who issues the guarantee and what exactly does it cover?
- What is excluded from making the roof complete?
What your quotation should confirm

- Leadwork, ventilation, insulation and Building Regulations route
- How hidden timber defects and other variations will be evidenced and priced
- Workmanship guarantee, product cover, payment terms and completion documents
What to check next
- Create a line-by-line comparison
- Ask each contractor to clarify omissions
- Treat an unexplained low quote as risk, not automatic value
When should you ask a roofer to inspect it?
Get a measured, written quotation before committing to substantial work. Ask questions wherever wording is vague, and insist that hidden defects are photographed and priced for approval before extra work proceeds, except where immediate safety action is unavoidable.
Safety first: do not climb onto a roof without suitable access, training and protection. Keep clear of loose coverings, unstable ceilings and water near electrical fittings.
