How to Compare Roof Quotes: Fixed Price vs Day Rate (2026 UK)
Most roof quotes in 2026 come one of two ways: a fixed price for the whole job, or a day rate charged per roofer (typically £200–£300 a day, plus a labourer at £120–£170). Fixed price gives you cost certainty and is best for defined work like a full re-roof or a new flat roof. A day rate can be cheaper for small repairs where nobody can see the full extent of the problem until the tiles come off. The trick is comparing them like-for-like.
Fixed price vs day rate — the short answer
- Fixed price: one agreed total for the whole job — best for re-roofs, new flat roofs and any clearly-defined work.
- Day rate: typically £200–£300 per roofer per day — best for repairs and jobs of unknown scope.
- For cost certainty, a fixed-price quote almost always wins: the risk of overruns sits with the roofer, not you.
- Day rate is cheaper only when the job is genuinely small and finishes quickly — otherwise the meter keeps running.
- Always get it in writing and confirm whether you are being given a fixed quote or a non-binding estimate.
As a rule of thumb: if the roofer can see exactly what needs doing, ask for a fixed price. If the problem is hidden — a leak of unknown cause, suspected timber decay — a capped day rate with a written upper limit protects you from an open-ended bill.
Fixed Price vs Day Rate Roofing (UK 2026)
How the two pricing models compare on the things that actually matter.
If a roofer will only work on a day rate for a job that looks clearly defined, ask why — it can be a sign they are unsure of the scope, or hedging against their own estimate.
How to Compare Roof Quotes Fairly
Quote vs estimate
A quote is a fixed, binding price; an estimate is a best guess that can change. Always confirm in writing which one you have been given.
Same scope on every quote
Make sure each roofer is pricing the same materials, scaffolding, felt, battens and warranty — otherwise the cheapest number may be the smallest job.
Scaffolding and access
Scaffolding is a major line item. Check whether it is included or excluded — a low day rate that excludes access can end up dearer than a fixed price that includes it.
Cap the day rate
If you do go day rate, agree a written not-to-exceed figure and a daily update, so an open-ended repair cannot quietly run away with your budget.
