Roof replacement across the UK, done properly

20 years' combined experience. Marley-approved, CORC-accredited, Knauf-approved. Every job comes with a 10-year insurance-backed guarantee and a fixed-price written quote from a free comprehensive survey.

When you actually need a full roof replacement

A full roof replacement is a significant investment. It's rarely the only option, and we would rather tell you honestly when it isn't necessary than sell you a job you don't need. There are four situations where replacement is genuinely the right route:

Your roof has reached the end of its serviceable life. Concrete and clay tile roofs typically last 40–60 years. Natural slate can last 80–100 years. Once a roof is past its design life, patchwork repairs become false economies — the underlying felt, battens, and flashings are all deteriorating together, and a repair to one section usually reveals problems in another.

More than 25% of the tiles are damaged, cracked, or missing. Widespread tile failure is almost never a surface issue. It typically signals underlying structural or moisture problems that a full strip and reroof will resolve properly.

Structural sagging, timber rot, or persistent leaks. These indicate the roof structure itself needs attention. A repair that doesn't address the underlying cause will fail again within a year or two.

Closed-cell spray foam removal. If closed-cell spray foam has been applied to the underside of your roof, the only safe removal method is the exterior tile-off approach — which becomes a full reroof by consequence. We cover this in detail in our guide to reroofing after spray foam removal.

If your roof doesn't fall into any of these categories, we'll tell you at survey. A repair, partial replacement, or maintenance visit is often the honest answer.

What a Countrywide roof replacement includes

Every job we quote for includes the following as standard. There are no hidden extras added at completion.

Free comprehensive survey. Full external and internal roof assessment by a qualified surveyor. Written report with photographs and specific recommendations.

Fixed-price written quote. The price we quote is the price you pay. Any variations require written agreement before proceeding.

Full strip and reroof. Existing tiles, felt, battens, and flashings removed and disposed of under our waste carrier licence.

New breathable membrane. Modern breathable underlay replacing older bituminous felt — allows moisture to escape from the roof space rather than being trapped.

New treated battens and counter-battens where required, fixed to current British Standards.

Marley-approved tile installation where Marley products are used, retaining the manufacturer's guarantee.

All flashings, ridges, and valleys renewed or refitted as required. Leadwork carried out by qualified operatives.

Knauf loft insulation included where the reroofing scope triggers a Building Regulations upgrade requirement.

Building Control liaison — we submit all required notifications and provide the completion certificate at handover.

10-year insurance-backed guarantee. Underwritten by a third-party insurer, so your guarantee remains valid and enforceable even if we ceased trading.

Site clean and full handover. Property left clean and tidy, with all completion documentation provided.

What a roof replacement actually costs in 2026

Roof replacement pricing depends on roof size, pitch, tile choice, and access complexity. The ranges below are typical for jobs we have completed in the last twelve months and are inclusive of VAT.

Your fixed quote is confirmed after a free survey. We do not vary the price after work begins unless a hidden issue emerges that we and you agree in writing needs addressing.

All prices include VAT, stripping, scaffolding, new underlay, battens, tiles, all lead work, Building Control compliance and certification. Prices assume standard access and no significant structural remediation.

What affects the final price: Roof pitch and complexity increase scaffolding and labour costs. Chimneys, dormers, and multiple valleys add time to strip and reinstate. Steep pitches require additional edge protection. Listed properties require specific materials and slower working methods. Tile choice — natural slate is materially more expensive than concrete tile, and specialist tiles (handmade clay, natural stone) are more expensive again.

Roof replacement quotes vary widely because scopes vary widely. What matters is comparing like-for-like. A £6,000 quote that leaves flashings, ventilation, or Building Control compliance unaddressed will cost you more within five years than a £9,000 quote that includes everything. If a quote seems dramatically below the ranges above, ask specifically what is not included — that is usually where the difference lives.

The six-step process, from first call to final handover

We follow the same process on every job. It keeps disruption to a minimum and quality consistent.

1. Free survey. A qualified surveyor visits your property at a time that suits you. Full external and internal roof inspection, photographs, and discussion of your specific situation.

2. Written fixed-price quote. Delivered within 3–5 working days of the survey. Detailed scope, materials specification, timeline, and price. No obligation to proceed.

3. Scheduling. Once approved, we book a start date that works for you and your household. We give you a specific week rather than a vague window.

4. Site preparation. Scaffolding erected. Skip delivered. Site protection installed for driveway, gardens, and neighbouring properties.

5. Strip, prep, and reroof. Tiles removed and stacked or skipped. Felt and old battens stripped. Rafters inspected. New breathable membrane, battens, and tiles installed. Flashings, ridges, and valleys renewed.

6. Certification and handover. Site cleaned, scaffold removed, Building Control certification issued, 10-year insurance-backed guarantee registered in your name. Full completion pack provided.

Related services

Roof replacement often connects to related work — either included in the same job or worth considering while scaffolding is up.

Spray foam removal — closed-cell spray foam removal always involves reroofing as part of the safe removal method. If you have spray foam and are considering a roof replacement, we can survey and quote both in a single visit.

Chimney repair and leadwork — chimneys often need rebuild or lead flashing renewal at the same time as reroofing. Doing them together saves scaffolding costs.

Loft insulation — Knauf loft insulation is included in reroofing scopes where Building Regulations require an upgrade.

Flat roofing — many properties have both pitched and flat roof sections. We handle both in the same visit where required.

Areas we cover

Countrywide operates nationally for roof replacement and spray foam removal, with permanent offices in Bournemouth, Exeter, and Weymouth. From these three locations, we cover the whole of England, Wales, and Scotland.

For roofing, chimney work, and other regional services, our primary coverage is Dorset, Hampshire, and Greater Manchester. If you're outside those areas and need roof replacement specifically, call us — national coverage applies.

Frequently asked questions

How much does a full roof replacement cost in the UK?

For a typical 3-bed semi with concrete tiles, £8,000–£14,000 including VAT. For natural slate on the same property, £13,000–£20,000. Your fixed quote depends on roof size, pitch, tile choice, and complexity — we confirm the exact figure at survey.

How long does a roof replacement take?

For a standard semi-detached, 5–10 working days weather permitting. Complex roofs, listed buildings, or large detached properties can take up to three weeks. You'll get a specific timeline in your survey report.

Do you handle Building Control approval?

Yes. We liaise with Building Control on your behalf, submit all required notifications, and provide the completion certificate at handover. You don't need to deal with the council directly.

What does the 10-year guarantee cover?

Workmanship on the entire roof replacement — leaks, tile installation, flashing failures, structural elements. Because it's insurance-backed by a third-party insurer, the guarantee remains valid even in the unlikely event we ceased trading. Manufacturer guarantees on Marley tiles are separate and typically last 30–50 years.

Do you replace roofs on listed buildings?

Yes, and we handle the listed building consent process where required. Listed roof work needs specific materials and slower working methods. We assess this at survey and confirm the scope before any quote is issued.

Do you offer finance?

Yes. We offer flexible finance options including 0% interest deals on qualifying jobs, so you can spread the cost. Finance is subject to status and provided by our finance partner. Details available at survey.

Will a new roof add value to my home?

Yes. A surveyor-approved new roof removes a common "defect" flag from mortgage valuations. Most estate agents report that a new roof adds 2–5% to a property's marketable value, and it removes a major obstacle to sales completions on older properties.

Is my current roof beyond economic repair?

Only a survey will tell you for certain. Generally, if repair costs would exceed 30–40% of the cost of a full replacement, or the roof is over 30 years old and beginning to show widespread failure, replacement is more economical long-term. We give you an honest assessment at survey — including telling you if a repair is the better route.
