How much does a slate roof cost in Stroud?

MyBuilder's slate roof cost guide, updated 21 August 2026, puts a slate re-roof at £100 to £180 per m² installed. That is the roof slope area, not the floor area of the house, and it covers stripping, new battens, underlay, slates and labour. The wide spread is explained largely by the slate itself, so the guide splits it by origin.

The guide also offers one worked example, a semi with Spanish slate, at £7,000 to £10,000. Treat that as a marker rather than a rule, because the size of the slopes and the number of features on them change the answer quickly.

Turning a rate into a budget

To see how the arithmetic works, take a hypothetical roof with 50 m² of slope. At £100 to £130 per m² for Spanish slate that is £5,000 to £6,500; at £140 to £180 per m² for Welsh slate it is £7,000 to £9,000. Those totals leave out scaffold and anything else extra, so read them as the covering and labour only. Your roof's slope area is measured at survey from the roof itself, since the plan area of the house understates a pitched roof.

The sources differ in how they build the rate, which is why a quote can sit outside a range without being wrong. Ask what the quote includes: whether battens and underlay are renewed, whether the figure includes the ridge, and whether scaffold and waste sit inside the per-metre rate or outside it.

Most slate work is repair, not replacement. MyBuilder's slate guide gives £60 to £120 for replacing a single slate and £150 to £350 for five to ten slates. The first slate is expensive because the visit, access and set-up cost the same however small the job; the next few cost far less each. That is why a short list of slipped slates is better done in one visit than one at a time.

For larger patches, the Checkatrade roof repair cost guide (header updated 10/26, body last updated June 2026) gives natural slate repairs at £150 to £220 per m², excluding VAT and excluding access. The same guide prices concrete tile repairs at £90 to £120 per m² and clay at £110 to £160, so slate sits at the upper end of pitched coverings. Skilled hand work on a brittle natural material explains much of that.

When repairs stop making sense

Repair costs rise with the number of visits. When slipping spreads over an entire slope, the nails holding them may be failing, and patching one area leads to patching the next. At that point the sensible comparison is between a series of repair invoices and the per-m² re-slate rate above. Our guide to the case for and against slate covers how repair skills and ongoing upkeep weigh against the up-front price.

The ridge is the horizontal join at the apex. A hip runs down the outside corner of a hipped roof, wherever two slopes turn the corner together. On many slate roofs these are finished in clay or stone ridge pieces, and they are extra to the slating.

Dry ridge means the ridge pieces are held by mechanical fixings and a ventilated system rather than relying on mortar. Under BS 5534:2014 mortar bedding is no longer trusted to hold ridge and hip pieces by itself, which is why a re-bed normally comes with fixings.

Lead and chimney details

Flashings are strips of lead that seal the junction between a slate slope and a chimney, wall or dormer. MyJobQuote, last updated 22 September 2026, puts a chimney flashing patch at £150 to £250, and a full chimney flashing replacement at an average of £570. These items often turn up in a slate job because the slates around a chimney are disturbed to get the lead in. Our slate roof maintenance guide explains why flashings are checked at every inspection.

Three costs sit under almost every slate quote, and they are easy to overlook when comparing per-metre figures.

Labour and day rates

MyBuilder gives a slater's day rate of £200 to £300, and a general roofer's day rate of £250 to £300. In its full re-roof guide, labour runs at £50 to £130 per m² across all coverings. Slating is slower than tiling because each slate is smaller and individually fixed, so a slate job tends to run longer. A day rate is useful for small repairs, but for a full re-slate the quote should make clear how many days the work will take.

Scaffold

Scaffold is needed on almost any re-slate. For a re-roof, MyBuilder quotes about £1,125 for scaffold and Checkatrade £700 to £1,300. Narrow lanes, steep drives or a terrace with no rear access can push scaffold above the typical range, because boards have to be carried or the pavement licence adds time. We build that into the quote rather than finding it on the day.

Waste and making good

Disposal is quoted by MyBuilder at £100 to £1,000 for a re-roof, depending on how much comes off and how far it must travel. Old slates are heavy, and a stripped roof can leave a large pile. Where old slates are sound they can sometimes be re-used on the same roof, which reduces both waste and new material, a trade-off covered in our hub page.

VAT is normally charged at 20% on re-roofing and repairs. Some of the Checkatrade figures above are shown excluding VAT, so check which basis a figure uses before comparing it with a quote that shows VAT.

The ranges above are national averages. On a particular roof, several things move the price, and most are visible at survey.

Access and the lie of the land

Stroud town and the surrounding villages include steep streets, terraces cut into hillsides and houses reached by narrow lanes. A roof that can be reached by a lorry on a flat drive is cheaper to strip and re-cover than one where materials are hand-carried or lifted in stages. At survey we note how the site is reached and build that into the quote, so the day holds no surprise.

Roof shape and detail

Hips, valleys, dormers and chimneys each add cutting and flashing. A plain gable slope is the lowest-cost slate to lay. The same area broken up by two valleys and a dormer takes more hours. Our Welsh, Spanish or Brazilian slate comparison covers the material side, which is the other big variable.

The structure under the slate

Rotten battens, failed sarking boards (the boarding some older roofs have under the slates) or weakened rafters add cost once the roof is open. A survey that checks the loft from below reduces the chance of surprises, although it cannot see everything.

Protected buildings and Building Regulations

Listed status or a conservation area can dictate materials and consent. Stroud District has 41 conservation areas, so check with the council's planning team. A full re-slate usually affects more than 50% of the roof, so Building Regulations approval applies and Part L can require a thermal upgrade. Insulation adds cost; the VAT on fitting it in a house is at the zero rate until 31 March 2027.

Because the ranges here are national, the useful test of a quote is whether you can see where each pound goes. Following the survey, our written quote takes in scaffold, the strip, slate, labour, waste and making good. A quote that never says what it covers gives you nothing to compare.

Questions to put to any slate quote

• Is the slate Welsh, Spanish or another origin, and what size and thickness?
• Are battens and underlay renewed, or are the existing ones kept?
• Are the ridge and hip re-fixed, and how?
• Is lead flashing renewed or retained, and in which code?
• Is scaffold included, and is waste carried away?
• Does the price show VAT?

Like for like

If your roof is slate, the sensible comparison is slate with slate. A quote for a lower-cost covering saves money now but changes the look, and on a protected building it may not be allowed. We keep slate as slate unless you ask otherwise and the building allows it.

Notifiable work comes with the Building Regulations paperwork handled by us, and the site is left clear. Already holding another quote? Email it with some pictures of your slopes and we will compare the scope.
