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.
When Fixed Price Wins — and When a Day Rate Does
There is one question that settles which pricing model to ask for: how clearly can the roofer see the whole job before the first tile comes off?
Fixed price wins when the scope is visible
A full re-roof, a new flat roof, or replacing a defined run of tiles, ridge or flashing can all be measured and priced up front. You get budgeting certainty and the roofer absorbs any overrun, so this is the model to insist on for anything you would call a project rather than a patch-up. Our roof replacement cost guide shows the going rates to sense-check a lump sum against.
A day rate wins when the extent is unknown
A leak of unclear origin, hidden rot found only when the covering is stripped, or a small urgent repair after a storm are all hard to price blind. A day rate also suits jobs where you are project-managing and feeding work to the roofer day by day. Agree a written not-to-exceed figure so an open-ended repair cannot quietly outgrow your budget.
The awkward middle ground is the re-roof where hidden decay is likely. Pure fixed-price pricing here forces the roofer to either gamble or load the quote with contingency; a fairer answer is a fixed price for the visible work plus a clearly-stated provisional sum — for example a rate per metre of replacement rafter or batten — that is only charged if the timber is actually found to be rotten once the roof is open.

What a Proper Roofing Quote Itemises
Two quotes are only comparable when they cover the same work. A thorough written quote should break the job down line by line rather than give a single round number:
- Access and scaffolding — often a four-figure line on its own; confirm it is included, not added later.
- Strip and waste removal — tear-off of the old covering plus skip or tipping fees.
- Underlay and battens — breathable felt and new treated battens, not a re-use of old timber.
- Covering and fixings — the exact tile, slate or membrane, with nails, clips and the manufacturer named.
- Flashings and detailing — chimney, verges, ridge, valleys and any lead or dry-fix work.
- Provisional sums — a stated rate for replacing any rotten rafters or decking found on strip, so surprises are priced in advance.
- Warranty and payment terms — the length and backer of any guarantee, the payment schedule, and any retention held until sign-off.
The reason detail matters is the strip-and-inspect problem: nobody can be certain what is under the tiles until they come off, which is exactly why a pure fixed price can hide either a padded contingency or a nasty variation later. A retention — holding back, say, 5% until a week or two after completion — gives you leverage to get snags put right. For unbiased homeowner guidance on vetting a roofer, the trade body NFRC's advice on choosing a contractor is a good starting point: ask whether the roofer belongs to a recognised body, ask to see proof of public-liability insurance, and check it yourself rather than taking it on trust.
Red flags to walk away from
No written scope
A verbal price with nothing itemised is impossible to hold anyone to. Insist on a written quote or estimate for anything beyond a tiny emergency repair.
Cash-only or huge deposit
Cash-only pricing and a demand for a large up-front payment are classic warning signs. A modest deposit for materials is normal; paying most of the job before work starts is not.
Storm-chasers at the door
Traders who cold-call after bad weather claiming they spotted a problem from the road pressure you into signing on the spot. Never agree there and then — get independent quotes.
A price far below the rest
If one number is wildly under the others it usually means a smaller scope, thinner materials or excluded access — not a bargain. Check what has been left out before you celebrate.
