Why Two Roofers Can Quote Very Different Prices for the Same Job
If you've asked three roofers to quote for the same work and received three very different figures, you're not alone. A difference of £500 to £1,500 or more on a single job is entirely normal, and it doesn't automatically mean someone is trying to overcharge you — or that the cheapest quote is the bargain it appears to be.
Understanding what drives those differences helps you make a smarter decision, protect your home, and avoid costly mistakes. Here's what we see on the ground every day working across Mildenhall and the surrounding villages.
What's Actually Included in the Price?
The single biggest reason quotes vary is what each contractor has actually priced. One roofer may include stripping the old felt, replacing damaged battens, and disposing of all waste as standard. Another may quote for tiles only and charge separately for everything else once work has started.
Before you compare figures, make sure every quote answers these questions:
- Is scaffolding included? On a typical semi-detached in Mildenhall, scaffold hire can add £400–£800 to a job. Some contractors exclude it deliberately to keep the headline figure low.
- What happens to the old materials? Skip hire or waste disposal should be itemised.
- Are replacement battens and felt included? On a full roof replacement, these are non-negotiable — any quote that skips them is cutting corners.
- What's the guarantee period? Workmanship guarantees vary from one year to ten. Materials warranties depend on the manufacturer.
A quote that looks £600 cheaper on paper may actually cost you more once hidden extras appear on the final invoice.
Materials Make a Significant Difference
Not all tiles, felt, or flat roofing membranes are equal, and the price gap between budget and mid-range materials is substantial. A contractor using a quality breathable membrane and graded concrete tiles will quote more than one using the cheapest alternatives — and the results will last longer in our climate.
Here in Mildenhall, we deal with some of the driest conditions in the UK, but that doesn't mean roofs have an easy life. Cold easterly winters, occasional driving rain, and significant temperature swings between seasons put real stress on roofing materials. Cheaper felt and low-grade fixings tend to fail faster in these conditions than in milder parts of the country.
For flat roofs in particular, material quality is everything. A GRP fibreglass or high-quality EPDM system installed correctly will outlast a cheap felt-and-pour job by fifteen years or more. Our flat roofing work always uses materials with a proven track record rather than whatever happens to be cheapest at the merchants that week.
Contractor Experience and Overheads
A sole trader working from a van with no employees will often quote less than an established local company. That's not inherently a problem — there are excellent one-man bands out there — but it does mean the risk profile is different.
Established roofing companies carry proper public liability insurance, pay for ongoing training, and stand behind their work with the resources to come back if something goes wrong. Checking that any roofer you hire is registered with the National Federation of Roofing Contractors (NFRC) gives you an independent standard to measure against.
Labour costs also vary with experience. Specialist work — lead work around chimney flashings, for example — requires a different skill level to basic tiling, and a roofer who does it well will charge accordingly. Cutting costs here often leads to leaks within a couple of years.
Red Flags to Watch Out For
Most roofers are honest, but the following should make you pause:
- Cash-only with no written quote. Legitimate contractors provide a written breakdown.
- Pressure to sign immediately or claims that the price is only valid for 24 hours.
- No physical address and no verifiable track record in the local area.
- Quoting without inspecting the roof. It's impossible to price a job accurately from the ground or from photos alone.
- Asking for full payment upfront. A reasonable deposit (typically 10–25%) is normal; full payment before work starts is not.

How to Compare Quotes Fairly
Line up every quote side by side and make sure you're comparing the same scope of work. If one contractor has itemised scaffolding separately and another has buried it in the total, adjust accordingly. Ask each roofer to clarify anything that isn't explicitly listed — a good contractor will answer without hesitation.
The lowest quote is rarely the best value, and the highest isn't necessarily the best quality. What you're looking for is a contractor who can clearly explain what they're doing, why, and what it will cost — with no surprises.
