Short answer
As a typical UK guide, a full re-roof usually costs around £5,000 to £9,000 on a standard semi-detached house — less on a small terraced home, and £9,000 to £15,000 or more on a large detached. Scaffolding, roof size, the tile or slate you choose, and whether the felt and battens need work all move the price. CPAGM doesn't fit new roofs, but we inspect honestly and handle repairs from £95 — often saving a re-roof you don't yet need.
What a 'new roof' actually means — and why it costs what it does
A "new roof", or a re-roof, means stripping the old covering back, checking the timbers, laying fresh breathable felt (underlay) and battens, and re-covering the whole roof in new tiles or slate. It's one of the biggest single jobs a house ever needs, and the price is driven by the area of the roof, its pitch and shape, the covering you pick, and the access — plus whatever the strip reveals underneath.
Scaffolding alone is a real chunk of the cost before a single tile is touched, and a steep or cut-up roof with valleys, dormers and chimneys takes far longer than a simple two-slope semi. That's why a terraced house comes in lower than a detached, and why two houses on the same street can be quoted very differently.
Around Chester, Cheshire and the Wirral there's a real mix of roofs. The Victorian and Edwardian terraces in Hoole, Handbridge and Boughton tend to be natural slate, which is dearer to replace properly than the concrete interlocking tiles on a post-war Blacon or Lache semi. Older slate roofs also often hide tired timbers and brittle battens once you strip them, and a re-roof is the moment that comes to light. Our weather off the Irish Sea is what wears roofs out in the first place — years of driving rain, gales lifting ridge tiles, and freeze-thaw cracking older clay and slate.
The honest truth, though, is that most roofs people worry about don't need replacing yet. A lot of "I think I need a new roof" calls turn out to be a slipped tile, a failed flashing or a moss problem — and that's a fraction of the cost.
New roof cost — typical UK guide prices
| Job | Guide price | What affects it |
|---|---|---|
| Small terraced house — full re-roof | £4,000–£7,000 | Simple two-slope roof, concrete tiles, straightforward access |
| Semi-detached house — full re-roof | £5,000–£9,000 | The most common Chester re-roof: scaffolding, felt, battens and concrete tiles |
| Detached house — full re-roof | £9,000–£15,000+ | Larger area, more complex roof shape, valleys and chimneys |
| Natural slate instead of concrete tile | Add 30–60% | Common on period Hoole and Handbridge homes; reclaimed slate costs more again |
| Scaffolding (part of the total above) | £800–£1,500 | Needed on almost any two-storey re-roof before work starts |
| New felt, battens or timber repairs | Varies | Only known once the old covering is stripped and the roof is open |
| Flat roof replacement (garage / extension) | From £1,800 | EPDM rubber or felt on a small flat roof — priced by area |
Clearly-labelled typical UK guide prices to set expectations only — not a CPAGM quote. A re-roof is a specialist job and CPAGM doesn't carry it out: we inspect your roof, tell you honestly whether you need one, and point you to a reputable roofing contractor for a firm quote. The real price is always confirmed after a proper survey, because pitch, covering, access and what the strip reveals all change it.
What actually drives a re-roof quote up or down
Five things move a roof-replacement price more than anything else. First, size — roofers price mainly by area, so a big detached in Upton or Tarporley naturally costs more than a compact terrace in Boughton. Second, pitch and complexity: a steep roof, or one broken up by valleys, dormers, hips and chimneys, is slower and more dangerous to work on than a plain two-slope, and the labour reflects that.
Third, the covering. Concrete interlocking tiles are the most economical; plain clay tiles cost more; and natural or reclaimed slate — common on Chester's period streets — sits at the top, typically adding 30 to 60 per cent over concrete tile. Fourth, scaffolding and access: nearly every two-storey re-roof needs a scaffold before work can start, and a tight terrace, a corner plot or a property on a busy road can push that cost up.
Fifth, and the one nobody can price precisely up front, is what's underneath. Once the old covering is off, tired rafters, rotten battens or failed felt may need replacing — and on older roofs that's common. A good contractor allows for it, inspects first, and gives you a range rather than a single tempting figure that quietly grows once the scaffold is up.
What CPAGM actually charges — roof repairs & inspection
| Job | Guide price | What affects it |
|---|---|---|
| Slipped tile repair | From £95 | Re-fixing or replacing slipped, cracked or missing tiles or slates |
| Small roof repair | From £150 | Localised repairs — flashing, a small area of tiles, ridge re-bedding |
| Storm damage inspection and report | From £95 | A proper look after wind or heavy rain, photographed, with an honest write-up for you or your insurer |
These are real CPAGM prices for the repair and inspection work we do carry out — we don't fit full new roofs. Every job is confirmed after you send a few photos and the details, because access, the covering and the extent of the damage change the scope.
How to tell whether you really need a new roof
- 1
Read the warning signs from the ground
Sagging in the roofline, lots of slipped or missing tiles across the whole slope, daylight or damp visible in the loft, repeated leaks in different spots, and crumbling mortar along the ridge all point towards a roof near the end of its life — not just one bad spot.
- 2
Count the cost of patching, honestly
If you're paying for the same kind of repair every winter, the patches are adding up and the underfelt has likely failed. At that point a re-roof can be the cheaper long-term call. If it's a one-off slipped tile, it almost certainly isn't.
- 3
Get an honest inspection before you commit
A proper look at the roof — and the loft underneath — tells you far more than a sales quote. CPAGM will inspect it, photograph it and give you a straight answer on whether it's a repair, a few more years of maintenance, or a genuine re-roof. Our storm damage inspection and report is from £95.
- 4
Only then get quotes for the work you actually need
If it really is a re-roof, get two or three written quotes from established local roofing contractors, and check they're insured and offer a guarantee. If it's a repair, you've just saved yourself thousands.
Don't get talked into a full roof you don't need
A new roof is a five-figure decision, and roofs are one of the things doorstep and storm-chaser traders push hardest — telling worried homeowners the whole roof has 'gone' when a flashing repair would do. Never agree to a re-roof off a quick look or a scare. Get the roof properly inspected, get it in writing, and get a second opinion before you sign anything. And never climb up to check it yourself — falls from height are the single biggest cause of serious injury in UK home maintenance, and a wet or mossy roof is treacherous.
Repair and maintain vs full re-roof — which do you actually need?
| Repair & maintain | Full re-roof | |
|---|---|---|
| Typical trigger | A few slipped tiles, one leak, storm damage in one area, moss build-up | Widespread tile failure, sagging, failed underfelt, leaks in several places |
| Guide cost | From £95 for a slipped tile, from £150 for a small repair | £5,000–£9,000 for a semi; more for a detached (typical UK guide) |
| How long it lasts | Buys years if the rest of the roof is sound | A new roof — typically 40–60 years for slate, decades for tile |
| Disruption | Usually a single short visit, no scaffolding | Scaffolding, several days of work, larger spend |
| Who does it | CPAGM — repairs, roof cleaning and roofline maintenance | A specialist roofing contractor — we'll recommend a good one |
Why an honest inspection first can save you thousands
The reason we lead with an inspection rather than a re-roof quote is simple: a great many roofs we're called out to look at aren't finished — they're just neglected. Clearing moss before it lifts tiles, re-fixing a handful of slipped tiles early, re-bedding ridge tiles and renewing a tired flashing can add years to a fundamentally sound roof, for a few hundred pounds rather than several thousand.
A premature full replacement is one of the most expensive mistakes a homeowner can make, and it's usually made under pressure — after a storm, or after a doorstep trader has been up a ladder and come down shaking their head. An independent look, with photos, gives you the facts before you spend. If the covering and felt really are failing across the whole roof, we'll tell you plainly and point you to a good local contractor. If they're not, we'll fix what needs fixing and you keep the rest of your money.
CPAGM covers Chester and roughly a 45-minute radius — Hoole, Handbridge, Upton, Saughall, Frodsham, Northwich, Ellesmere Port, Tarporley and the wider Cheshire, Wirral and Flintshire area — so a same-week look is usually straightforward wherever you are.
Signs it may be time to think about a re-roof
- Slipped, cracked or missing tiles across the whole slope, not just one spot
- A visible dip or sag in the roofline seen from across the street
- Daylight, damp patches or dark staining in the loft, especially after rain
- Leaks appearing in several different places, or the same patch back every winter
- Crumbling mortar along the ridge and around the chimney, and lots of granules or slate fragments in the gutters
Frequently asked questions
How much does a new roof cost?
As a typical UK guide, a full new roof (a re-roof) costs around £5,000 to £9,000 on a standard semi-detached house, less on a small terraced home, and £9,000 to £15,000 or more on a large detached. The figure depends on the roof's size and pitch, the tiles or slate you choose, scaffolding, and whether the felt, battens or timbers need work. CPAGM doesn't fit new roofs, but we inspect honestly and repair from £95.
What is the cost of a new roof in the UK?
Across the UK a new roof typically costs around £5,000 to £9,000 for an average semi-detached house, roughly £4,000 to £7,000 for a small terrace, and £9,000 to £15,000 or more for a large detached — including scaffolding, stripping the old roof, new felt and battens, tiles and labour. Natural slate adds 30 to 60 per cent over concrete tile. These are guide ranges only; a firm price needs a survey.
How much does a new roof cost on a semi-detached house?
A new roof on a typical semi-detached house usually costs around £5,000 to £9,000 as a UK guide, including scaffolding, felt, battens and concrete tiles. Choosing natural slate, or finding rotten timbers once the roof is stripped, pushes it higher. A steep or cut-up roof also costs more than a plain two-slope one.
What is a re-roof and how much does it cost?
A re-roof means stripping the old covering, checking and repairing the timbers, laying new breathable felt and battens, and re-covering the whole roof in new tiles or slate. As a UK guide it costs around £5,000 to £9,000 on a semi, less on a terrace and more on a detached. It's a specialist job — CPAGM doesn't carry it out, but we'll inspect and tell you honestly whether you need one.
How much does a roof replacement cost?
A full roof replacement typically costs from around £4,000 for a small terraced house, £5,000 to £9,000 for a semi, and £9,000 to £15,000 or more for a large detached, as a typical UK guide. The main drivers are roof size, pitch and complexity, the covering (concrete tile, clay or slate), scaffolding, and whether the felt, battens or rafters need renewing.
Does CPAGM fit new roofs?
No — a full re-roof is a specialist job and we don't carry it out. What we do is inspect your roof honestly, tell you whether you actually need one, handle repairs (slipped tiles from £95, small roof repairs from £150), roof cleaning and roofline maintenance, and recommend a reputable local roofing contractor if a replacement is genuinely needed.
How do I know if I need a new roof or just a repair?
You likely only need a repair if the problem is in one spot — a slipped tile, a single leak, a failed flashing or moss build-up. You may need a re-roof if tiles are failing across the whole slope, the roofline is sagging, the underfelt has gone, or leaks keep appearing in several places. An honest inspection with photos is the only reliable way to tell — never decide off a doorstep scare.
What makes one roof more expensive to replace than another?
Five things: the roof's area (bigger costs more), its pitch and complexity (valleys, dormers and chimneys add labour), the covering you choose (concrete tile is cheapest, slate the dearest), scaffolding and access, and what the strip reveals underneath — rotten battens, tired felt or damaged rafters. That last one can't be priced exactly until the old roof is off.
How long does a roof last in Chester's climate?
A well-laid concrete tile roof typically lasts 40 to 50 years and natural slate can go well beyond that, but our wet, windy weather off the Irish Sea and the underfelt beneath the tiles are usually what wear out first. Many roofs that look tired just need maintenance — moss clearing, a few tiles re-fixed, ridge re-bedding — rather than replacing.
Will a roof clean or repair save me needing a new roof?
Often, yes. Clearing moss before it lifts tiles, re-fixing slipped tiles early and re-bedding ridge tiles can add years to a sound roof for a few hundred pounds. A re-roof is only worth the money once the covering and felt are failing across the whole roof — which an honest inspection will confirm before you commit to a five-figure job.
Can I get a grant or pay in stages for a new roof?
There's no general government grant for re-roofing a private home, though some energy-efficiency schemes touch on roof insulation — check GOV.UK for what's current. Most roofing contractors offer staged payments; never pay the full amount up front before work starts, and get the scope in writing first.
How do I avoid being scared into a re-roof I don't need?
Get the roof properly inspected with photos, get any re-roof quote in writing with a clear scope, and get a second opinion. Use established, insured local contractors and check them on a scheme like TrustMark — and walk away from anyone pressuring you to decide on the spot. An independent inspection (from £95) is far cheaper than a roof you didn't need.
