What roof work costs in Stroud, and how a quote is built

A roof price has more moving parts than most trades. Two houses of the same size can need very different work, because the cost is driven less by the footprint than by the condition of what is beneath the covering, the type of covering itself, and the route to the ridge.

That is why national guides show wide bands. MyBuilder's 2026 figures put a full re-roof at £5,000 to £12,000, while Checkatrade's 2026 guide describes a national average of about £8,000 with most jobs between £4,000 and £19,000. These sit on top of one another rather than conflict, because each reflects a different sample of jobs.

What a survey settles

• The covering, its condition and how much can be reused.
• The timbers beneath: battens, rafter feet, wall plate and any rot.
• The details: ridge, hips, valleys, chimneys, flashings and the roofline.
• Access, and the scaffold the roof needs.
• Whether Building Regulations approval, planning or consent questions apply.

Until those are known, a number is an estimate. After them, it can be a fixed price. A roofer who quotes a final figure from the pavement is quoting for a roof they have not seen, and the gap tends to reappear on the day as an extra.

VAT

Roofing on an existing house is normally standard-rated, so expect 20% VAT to appear on your quote. The one exception is insulation put into a home's loft or roof, which carries zero VAT until 31 March 2027. Checkatrade states its figures exclude VAT, so add it when comparing them with a quote that includes it.

Repair prices depend on what is broken and how hard it is to reach. MyBuilder's 2026 repair guide gives a broad £150 to £1,500, and breaks it down by scale:

• Minor repairs, £100 to £300.
• Moderate repairs, £500 to £1,000.
• Major repairs, £2,500 and above.
• Storm-damage fixes, £500 to £1,500.

Checkatrade's repair guide (updated 2026, excluding VAT and access) gives per-m² figures by covering: concrete tiles at £90 to £120, clay at £110 to £160, natural slate at £150 to £220, bitumen flat roofs at £100 to £140, EPDM at £120 to £170 and GRP at £130 to £180.

Common small jobs

A repair is where like-for-like matters most. A patch in the wrong material can fail sooner than the old roof around it. On stone, a repair is priced after the survey, because the stone, the access and the extent of the damage differ from roof to roof. Emergency work to stop a leak is a separate question: stopping the water comes first, ahead of any repair planning, and leaks and storm damage take priority. Our Building Regulations guide explains when a repair crosses into notifiable work.

A full re-roof is the largest roof bill most households meet. MyBuilder splits its £5,000 to £12,000 typical range into £5,000 to £8,000 for a gable roof and £8,000 to £12,000 for a hipped one. Checkatrade shows hipped roofs at £9,250 to £18,000, or £145 to £285 per m², and gables at £7,000 to £16,250, or £110 to £260 per m², all excluding VAT.

For natural slate, MyBuilder's guide puts installation at £100 to £180 per m², with Welsh slate at £140 to £180 and Spanish at £100 to £130, with a typical semi in Spanish slate at £7,000 to £10,000. Stone slate is generally about £160 to £210 per m² in Checkatrade's slate guide, which is a national range, not a Cotswold one.

What sits inside the total

• Labour: £50 to £130 per m² on MyBuilder's figures, or a day rate of £250 to £300 for a roofer and £200 to £300 for a slater.
• Scaffold: about £1,125 on MyBuilder's figures, or £700 to £1,300 in the Checkatrade guide.
• Disposal: £100 to £1,000, depending on volume and the type of waste.
• Materials: the covering, battens, underlay, lead and fixings.

Weight and approval

A re-roof can bring two sets of rules into play. Once the work reaches 25% of the building envelope or 50% of the roof, the Planning Portal's no-application rule falls away: Building Regulations approval applies, and Part L can add a thermal upgrade. A replacement 15% heavier or more also brings approval and a structural check. Our roof planning permission guide covers the separate planning question.

Flat roofs are priced per m², and the covering sets most of the rate. MyBuilder's 2026 flat roof guide gives a typical replacement at £2,800 to £7,500 for a whole roof, averaging about £75 per m². The per-covering ranges are:

What changes a flat roof price

Three things stand out. The first is the deck: a sound deck is simply covered, while a rotten one needs replacing. The second is insulation. A warm deck with insulation above the structure costs more than a cold one, and Part L treats re-covering with a new waterproof membrane as renovating the thermal element of the roof. The third is the fall. BS 6229 designs for a fall of 1:40 to achieve a finished 1:80, and correcting a roof that ponds means adding tapered insulation or firring.

Garages and conservatories

MyBuilder gives £700 to £1,000 for a flat roof over a single garage and £900 to £1,400 for a double. Conservatory roof replacement averages about £4,500, in a range of £2,000 to £10,000 or more, and a solid conservatory roof needs a Building Regulations application.

Many bills hide in the parts of the roof that are not the covering. These ranges come from MyBuilder (2026) unless stated.

Chimneys

Chimney repointing averages about £750, in a range of £500 to £2,000, and rises with house type: £200 to £700 for a bungalow, £600 to £900 for a semi with a side chimney and £900 to £1,500 for a semi with a central one. Flashing repair is £250 to £1,200. A stack rebuild is quoted at £2,000 to £10,000 or more. MyJobQuote's 2026 figures put a lead flashing patch at £150 to £250 and a full replacement at £350 to £460 without scaffold or £700 to £920 with.

Roofline

For gutters, fascia and soffit, MyBuilder gives about £150 per metre for fascia and soffit combined, soffit at £100 to £180, fascia at £80 to £150 and guttering at £30 to £70 per metre. Scaffold for roofline work is £20 to £40 per m². uPVC fascias are typically replaced every 10 to 20 years according to the same guide.

Roof windows

Installing a roof window costs £350 to £600 for a standard job, labour and fitting only, with a centre-pivot window itself around £305 and scaffold about £500. Part L sets a limit of 1.4 W/m²K for roof windows, so the window you choose has to meet it.

Cleaning and moss

Roof cleaning is typically £300 to £600 for flat roofs, £450 to £850 for pitched, £500 to £1,000 for slate and £400 to £750 for tile. Pressure washing may harm delicate tiles, MyBuilder cautions, and it prices manual scraping at £5 to £10 per m².

A roof survey is where a price becomes real. MyBuilder's 2026 inspection guide gives £150 to £500 nationally: £150 to £250 for a standard visual survey, £200 to £400 for a drone survey and £300 to £500 for a thermal one.

A survey by a roofing firm is a different thing from a surveyor's report for a house purchase. It should produce photographs, a list of faults ranked by urgency, and enough detail that you could take it to another roofer. The pictures of your own roof taken on the day are what make a written quote checkable.

Where we fit in

Typical ranges go up before any visit, and the written quote comes after it, so you can see what each pound buys. Stone is quoted as stone and slate as slate. If the job is notifiable, the consent is explained and the Building Regulations notification sent by us. The site is left clear at the end, waste included, and the work carries a written 10-year workmanship guarantee.

National ranges are a starting point. Several features of local housing and streets move a Stroud price, and a good survey tells you which apply.

• Scaffold on steep streets. Terraces cut into hillsides, tight lanes and shared passages complicate scaffold, and the price of getting to the roof can rise. The national figure of about £1,125 is for a typical house.
• Stone and slate. Slate repairs sit above tile in Checkatrade's per-m² figures, and stone is heavy to handle. Reusing sound slates saves new material but costs time in sorting.
• Access for materials. Where a lorry cannot reach, materials are carried or lifted, which adds labour.
• Waste. Stone and slate waste is heavy, and disposal runs £100 to £1,000 nationally.
• Consent and listed status. A listed home or a conservation-area address may need consent first, and drawings or a specification can add cost.
• Hidden defects. Rotten battens or rafter feet found on stripping are the main reason a final bill differs from an estimate. Ask for a stated rate before the job.

Stroud District Council names 41 conservation areas, so many valley and hill-village houses sit under some form of control. Unsure which applies to you? Put it to the council's planning team before ordering any material.
