It is the question every homeowner wants answered before they pick up the phone. Roof repair costs vary considerably depending on the type of fault, the access needed, the materials involved, and the extent of any underlying damage. This page sets out honest typical price ranges for the most common jobs, explains clearly what pushes costs up or down, and tells you what to look out for when comparing quotes.
There is no single price for a roof repair. A roofer who gives you a number without seeing the roof is guessing, and those guesses rarely hold when the work starts. What we can do is explain what drives the cost of each type of job, so you have a realistic sense of what to expect before anyone visits.
Roof repairs range from replacing a single cracked slate to relining a valley, repointing an entire ridge, or stripping and re-dressing all the lead flashings around a chimney stack. The most common jobs are:
The figures below reflect typical UK market rates. Your actual quote will depend on what a roofer finds when they inspect your roof in Melbourn. These ranges are a guide to what is reasonable - not a ceiling or a floor.
Replacing two to five broken or slipped concrete or clay tiles on a standard two-storey house typically costs £150 to £350, including access by ladder. Natural slate replacement in the same quantity is usually £200 to £400, partly because slate is more expensive to source and partly because matching older slates (Welsh blue, Westmorland green, reclaimed grey) takes more care and knowledge than matching a standard concrete tile.
What pushes this cost up: the tiles are on a hard-to-reach section of roof requiring scaffolding; the tiles are an unusual size or profile that cannot be sourced from a local merchant; there is damaged felt or timber beneath that needs attention at the same time. What brings it down: the tiles are a standard modern profile, access is straightforward by ladder, and only one or two tiles are involved.
Repointing a ridge on a semi-detached house typically costs £200 to £500, depending on the length of the ridge and the condition of the existing bedding mortar. If the ridge tiles themselves are cracked or damaged, add the cost of replacements - clay or concrete ridge tiles are generally £5 to £15 each, with handmade or period-matched ones considerably more.
Hips are the external angled junction on a hipped roof where two slopes meet. Repointing hips is priced by the linear metre in the same way as ridges. If both a ridge and hips need repointing, some of the access cost is shared, which makes the combined job more economical than two separate visits.
An alternative to mortar bedding is a dry-fix mechanical system, where ridge and hip tiles are secured with purpose-made clips and a ventilated foam filler rather than mortar. Dry-fix systems cost more to install - typically 20 to 40 per cent more than a traditional mortar re-bed - but they are longer lasting in exposed positions because there is nothing to crack or wash out. A dry-fix ridge or hip does not need repointing again.
Flashing repairs around a chimney stack are among the more variable repair costs because the scope depends so much on what is found. If the lead itself is sound but the mortar pointing that holds its top edge into the brickwork has failed, repointing that joint and re-dressing the lead typically costs £150 to £300 for a standard stack. If the lead has cracked, pulled away at a joint, or corroded through, a full lead replacement is needed.
A full lead flashing replacement around a typical chimney stack costs £400 to £800, sometimes more for a large or complex stack. This covers the cost of new lead sheet (which is priced by weight - Code 4 or Code 5 lead is standard for most roof flashings), the labour of cutting, dressing and stepping the lead into the mortar joints, and pointing the exposed edges on completion.
Flashings at dormers and abutment walls (where a roof meets a wall) follow similar logic: the cost depends on the linear metres of flashing involved and whether replacement or repair is the right call. Zinc and purpose-made aluminium flashing tape are sometimes used as alternatives to lead, particularly in smaller or less exposed positions. They are generally cheaper but not as long-lasting or as easy to re-dress if a problem develops later.
Valley repairs are at the higher end of individual repair costs because valleys handle the concentrated run-off from two roof slopes, and shortcuts here tend to fail quickly. Relining a lead valley on one section of a semi-detached house costs approximately £400 to £900 depending on length and access. Re-tiling a cut valley (where tiles are cut to fit the internal angle rather than using a lead lining) covers a similar range.
If damaged underlay is found beneath the valley during the repair, that adds to the cost because it should be replaced at the same time. Leaving failed underlay in place under a new valley lining means the water that gets past the repair has nowhere safe to go.
Small flat roof repairs - sealing a cracked felt seam, re-bonding a lifted edge, patching a blister - start at around £150 to £300 for a minor patch on a bay window or small outhouse roof. Larger flat roofs with more significant felt failure often reach a point where a full strip and re-cover is better value than repeated patching. A new felt or EPDM rubber covering on a typical bay window flat roof costs roughly £500 to £900; a full garage or extension roof covering is typically £1,200 to £3,000 depending on size and the system used.
EPDM rubber membranes are increasingly used on flat roofs and extensions. They are a single-piece membrane bonded across the whole deck, which removes the seams that are the most common point of failure on traditional felt. EPDM is generally more expensive upfront than felt but tends to outlast it significantly on a flat or very shallow-pitched surface.
Understanding the factors that increase a repair price helps you assess whether a quote is reasonable or inflated. The main cost drivers are:
Some jobs are genuinely straightforward and should be priced accordingly:
If a quote for one of these jobs is significantly higher than the ranges above, ask for a clear breakdown. A legitimate reason might be that access is harder than it looks, or the material is unusual - both of which should be explained without prompting.
A roof that is sound overall but has one or two faults should always be repaired rather than replaced. A targeted fix is cheaper, faster and avoids disturbing materials that are still doing their job. But a roof that is 35 to 40 years old, where the felt is perished, the mortar is crumbling along most of its length, and tiles are failing in multiple places, is a different conversation. Each individual repair on a roof in that condition tends to hold for a shorter time, and the cumulative cost of multiple visits over a few years can exceed the cost of a full re-roof.
A straightforward question to ask any roofer during the inspection is: if you fix the faults you can see today, what is the realistic expectation for the rest of the roof in the next three to five years? An honest answer to that question helps you decide whether a targeted repair or a planned replacement makes better financial sense.
A price quoted without a proper inspection is not a reliable guide to what you will pay. Before agreeing to any work, make sure the quote:
Vague quotes that describe the work in general terms give a roofer room to expand the scope once they are on site. Detailed quotes protect both parties.
Cambridge Roofers covers Melbourn and nearby areas including Royston, Cambridge, and the surrounding villages. If you have a repair that needs assessing, call us to arrange an inspection. We will look at what is actually wrong, tell you what we think is needed and why, and give you a price based on that - not on a guess from the pavement.
We do not recommend unnecessary work. If a targeted fix is the right answer, that is what we will quote for. If the roof has wider issues that affect how long a repair is likely to last, we will tell you that too, so you can make an informed decision.
