Is my roofer’s quote too expensive? What’s normal in the UK

Roofing is one of the hardest quotes for a homeowner to judge, because you cannot see most of what you are paying for and the work happens out of sight, two storeys up. That information gap is exactly where an inflated roofing quote hides. The good news is that a roofing quote has a small number of cost drivers, and once you know them, you can tell a fair price from a padded one.

This guide covers what legitimately moves a roofing price, the lines that often inflate it, and the red flags specific to roofs. For the underlying ranges, start with the new roof cost guide, and for the general method, how to tell if a quote is too high.

The legitimate cost drivers#

A higher roofing quote is often fair for reasons you can verify:

Strip-and-re-cover vs overlay. A full strip (removing the old covering, replacing membrane and battens, re-covering) costs more than laying new over old, and lasts far longer. Make sure two quotes you are comparing are doing the same one.

Tile or slate type. Concrete tiles, clay tiles, natural slate, and synthetic slate sit at very different price points. A quote specifying natural slate is legitimately dearer than one specifying concrete.

Roof size, pitch, and height. A steep, high, or complex roof (valleys, dormers, multiple aspects) takes longer and needs more scaffolding. A bigger, more awkward roof is fairly a bigger number.

Access and scaffolding. Safe access is essential and not free. The genuine cost of scaffolding is one of the biggest legitimate differences between quotes.

Where roofing quotes get padded#

Scaffolding left vague. If access is not itemised, it has either been absorbed at an inflated rate or left out to make the headline look low. Ask for it as a named line with a hire period.

Overlay priced as a re-cover. A quote that charges close to strip-and-re-cover money for what is actually an overlay is overpriced for the work being done.

Unspecified materials. "New tiles" with no type or brand makes the quote impossible to compare and easy to pad. Insist on the specific covering.

Flashing, ridge, and guttering bundled or missing. These should be itemised. Bundling them into a lump sum, or leaving them out and charging later, are both common.

Roof-specific red flags#

• Door-knock or storm-chaser roofers. A roofer who knocks unsolicited after bad weather, claiming to have "spotted a problem from the road," is a well-known pattern. Get an independent inspection before agreeing to anything. See signs of a rogue builder.
• Pressure to start immediately. Genuine roofers are booked up. Urgency is a sales tactic far more often than a real necessity.
• Cash-only, no paperwork. No written quote, no company details, no insurance certificate. Roof work is high-risk; you need the builder properly insured.
• A re-roof quote silent on Building Regs. A major re-cover is usually notifiable. Silence suggests inexperience or corner-cutting.

Sanity-check before you sign#

1. Is it a strip-and-re-cover or an overlay, and does the price match the work?
2. Is scaffolding itemised, with a hire period?
3. Are the tiles or slates specified by type or brand?
4. Are flashing, ridge, and guttering itemised?
5. For a major re-roof, is Building Control addressed?
6. Is the roofer insured, with a written quote and verifiable company details?

A quote that answers all six is one you can judge. A quote that dodges several is one to question before any money changes hands.
