Cost guide

Roof Replacement Cost by Roof Type and Property Size

Two variables set most of a replacement price: what is going back on, and how much of it there is. This page crosses those two so you can find the box your house sits in, rather than reading a single national average that fits nobody. Everything here assumes a full strip, new underlay and batten, dry fix ridge and renewed flashings.

  • Concrete tile, the lowest cost covering, 40 to 60 year life
  • Clay tile, holds colour, 60 to 80 year life
  • Spanish slate, mid cost natural stone, 50 to 80 year life
  • Natural Welsh slate, the long game, 80 to 100 year life
  • Synthetic slate, 30 to 50 year life, lighter on the structure

By covering, on a standard three bed semi

Concrete tile 7,500 to 12,500. Clay tile 10,000 to 16,000. Synthetic slate 8,500 to 14,000. Spanish slate 10,000 to 16,000. Natural Welsh slate 14,000 to 22,000. Those are our working ranges with scaffold in, on a roof with sound rafters and normal access.

By property size

A mid terrace usually sits below the semi figures because you are covering less area and often scaffolding one elevation. An end terrace adds a gable. A detached typically runs a third to a half above the semi range for the same covering. A bungalow has a large roof area for the floor space, so it is rarely the cheap option people expect, though the scaffold is simpler.

What pushes a job to the top of its range

Multiple valleys, dormers, a large or awkward chimney, cut roof rather than trussed, restricted access down a back lane, or timbers that turn out to be soft at the eaves. Any of those is a real cost, and all of them are visible at survey, which is why the survey is where the honest number comes from.

Where you are matters too

Roof stock is not evenly spread across our patch. Slate dominates the older Tyneside terraces, concrete tile dominates the post war and new town estates, and coastal streets pay more attention to fixings and flashings than inland ones. The city pages below go into what is typical where you live.

New roof cost for terraced and semi-detached houses

Terraces are usually the cheapest houses to re-roof per property because the roof area is smaller and scaffold and access are simpler. Our guide range for a straightforward mid-terrace concrete tile re-roof is £4,500 to £7,500. That is a different job from the standard three-bed semi ranges above: compare the covering and scope, not just the headline price. An end terrace with a gable, an extension beneath the eaves or restricted access can move away from that straightforward starting point. For a roof replacement cost UK semi-detached comparison, use the by-covering figures above, which include scaffold and assume sound rafters. Ask whether both slopes, flashings, disposal and any timber repairs are included before deciding how much to replace a roof will actually cost.

How much for garage roof replacement?

A single garage GRP roof typically costs £1,200 to £1,800, while a double garage GRP roof is £1,800 to £3,200. These are the site’s garage guide figures, not a fixed price for every building: the deck condition, roof area, edges and drainage still need checking. A new covering over a sound deck is not the same scope as stripping rotten boards and putting the falls right. When comparing the cost of a new roof, keep garage figures separate from pitched house roofs because the materials and access are different. See garage roof replacement for the work involved and ask for the deck and disposal to be named in the written quote.

Roof replacement cost, common questions

Can I change from slate to tile to save money?+

Sometimes, but concrete tile is heavier than slate and the existing rafters were sized for what is up there now. It is a structural question, not a shopping question, and we check it before quoting a change of covering.

Do you re-use the old tiles?+

On a conservation street or where a client wants the weathered look we will salvage and re-lay sound tiles, with new underlay and batten underneath. Expect breakage losses of ten to twenty per cent that have to be made up.

How much of the price is the scaffold?+

On a standard semi it is a modest but fixed slice, and it does not shrink if the roof is small. That is why little roofs can look expensive per square metre.

Is half a roof ever sensible?+

Yes. Re-covering one elevation is normal where the rear has failed and the front has years left, and it is a lot cheaper. We will say honestly whether the other side will follow soon.

How much does a new roof cost in the UK?+

Use the by-covering ranges above as a starting point, rather than a single UK average. For a standard three-bed semi, concrete tile is £7,500 to £12,500 and natural Welsh slate is £14,000 to £22,000, with the other coverings listed between them. These are our working ranges, not a national fixed tariff; roof size, access and timber condition affect the quote.

How much is a new roof on a terraced house?+

Terraces sit at the lower end of the house roof ranges because there is less area to cover and scaffold is usually simpler. Our guide puts a straightforward mid-terrace concrete tile re-roof at £4,500 to £7,500. End terraces and awkward access can cost more.

How long does a roof replacement take?+

A standard three-bed semi is usually three to five working days once scaffold is up, weather permitting. Larger roofs and complicated valleys or dormers take longer; agree the programme before work starts.
