What this means in practice
Compare quotations line by line, including VAT, scaffold, waste, exact products, insulation, ventilation, leadwork, timber allowances, Building Control, payment terms and guarantees. A low total created by missing essential work is not a saving—it is an unpriced variation waiting to happen.
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.
