A leak or a damaged tile in Dickleburgh needs attention quickly - left alone, the damage spreads far beyond the roof itself.

Roof repairs cover a wide range of work, from swapping out a single cracked tile to repointing a crumbling ridge, renewing worn flashings around a chimney stack, or re-fixing a lead valley that has started to lift. The job is rarely just what you can see from the ground. A tile that looks slightly out of place can be concealing a snapped batten beneath it, and a damp patch on a bedroom ceiling often traces back to a flashing failure several metres away from the stain.
Getting the right diagnosis matters as much as the repair itself. A proper inspection looks at the tile or slate condition, the pointing on ridges and hips, the state of lead or mortar flashings, the underlay where it is visible, and whether any battens show signs of rot. That is where the decision about repair versus replacement begins.
This is the question homeowners in Dickleburgh ask more than almost any other, and it deserves a straight answer rather than a sales pitch. The honest answer is that most roofs can be repaired, and for most homeowners in most situations, repair is the right starting point. But there are real circumstances where replacing the whole roof makes better financial sense, and knowing what those are saves you money in the long run.
Below is a practical guide to working through that decision yourself, so you know what to expect when a roofer comes to look at your roof and can ask the right questions.
Repair makes sense when the damage is localised. A handful of slipped or broken tiles, a section of ridge that has lost its mortar, a flashing that has lifted away from a chimney breast - these are all jobs where targeted repair is effective and proportionate. The rest of the roof is sound, the battens and underlay are in reasonable condition, and the repair will extend the roof's useful life without throwing money at a structure that does not need wholesale attention.
Age alone is not a reason to replace. A roof that is 30 or even 40 years old but has been maintained and where the tiles or slates are largely intact can still give you another decade or more with targeted repairs. Clay plain tiles, for example, can last 60 to 100 years if the originals are of reasonable quality. Concrete interlocking tiles from the 1970s and 1980s are more variable, but many are still performing well. The tile or slate itself is rarely the first thing to fail - flashings, pointing, and battens typically give way first.
Single tile replacement costs vary depending on the tile type, roof pitch and access. As a general guide, replacing a small number of standard concrete or clay tiles typically costs between £150 and £350 for labour and materials on a straightforward pitch. Ridge repointing on a standard semi-detached runs roughly £200 to £600 depending on the length of the ridge and the condition of the existing mortar. Flashing repairs, including lead dress and repointing, tend to fall between £150 and £500 per section depending on complexity.
There are situations where continuing to repair a roof becomes poor economics. The clearest sign is repeated call-outs to different sections of the same roof over a short period. If you have had ridge repointing done, then a flashing failure, then tiles slipping in two separate areas within three or four years, the roof as a whole is probably at the end of its serviceable life and you are spending money piecemeal on something that will need replacing anyway.
The condition of the underlay matters enormously here. Modern roofs have a breathable membrane or traditional felt underlay beneath the tiles. When that underlay is torn, friable or missing in sections, the roof loses its secondary barrier against wind-driven rain. Tiles alone do not make a roof watertight - the underlay does much of the work. If a roofer strips back damaged tiles and finds underlay that disintegrates on contact, that is a strong indicator that a full re-roof is more sensible than patching.
Batten condition tells a similar story. Timber battens rot over time, particularly at the eaves where water can sit, and in areas where the underlay has failed and moisture has reached the timber repeatedly. Rotten battens cannot hold new fixings reliably. If a significant proportion of the battens are soft, a re-roof is the only proper solution.
A full re-roof on a standard three-bedroom semi in the UK typically costs between £5,000 and £9,000, and on a larger detached property between £8,000 and £15,000 or more, depending on the roof area, pitch, access and tile type chosen. Those figures assume standard concrete interlocking or clay plain tiles. Natural slate costs more, both for the material and the additional labour. Set against the cost of three or four repair visits that do not address the underlying problem, a timely re-roof can be the cheaper option over five years.
Not every roof falls cleanly into one category or the other. On many older properties, one slope of a roof is in considerably worse condition than the other - perhaps a north-facing back slope that holds moisture and moss, while the front slope is still performing well. In those cases, stripping and re-roofing one slope while retaining and repairing the other is often the most cost-effective approach. It is a genuine option worth discussing rather than an all-or-nothing decision.
Similarly, on roofs where the main tiles are sound but the underlay has reached the end of its life, it is sometimes possible to carefully strip and re-lay the existing tiles onto new battens with new underlay beneath. This costs less than buying new tiles but still addresses the root cause. Whether the existing tiles are suitable for re-use depends on their condition, the tile type, and how many are lost or broken during the strip. A good roofer will give you an honest view on the numbers before work starts.
When a roofer comes to look at a problem, ask them to tell you what they found in the loft as well as on the roof surface. The underside of the rafters, the condition of the underlay where it is visible, and any staining on the timbers all provide evidence about how long a problem has been present and how widespread it is. A roofer who looks only at the outside and quotes quickly without checking the loft is missing half the picture.
Ask specifically whether the underlay and battens in the affected area are sound, and whether the rest of the roof shows similar signs of deterioration. Ask what the repair will achieve and how long it is likely to hold. If the answer is vague, ask again. A roofer who knows the work can tell you plainly why a repair is appropriate or why it is not.
Get the scope of work written down before anything starts, even if it is just a brief description. That way you know what has been agreed and can check it has been done.
The following covers the main categories.
A repair should leave the roof in at least as good a condition as before the problem started, and ideally better. Tiles should be bedded or mechanically fixed correctly, not just pushed back into position without attention to the fixing. Mortar pointing should be mixed and applied at the right consistency and finished neatly. Lead flashings should be properly dressed into any chases and pointed to prevent water ingress.
Debris from the repair - old mortar, broken tile fragments, any packaging - should come off the roof and not be left in gutters or on the surrounding ground. Scaffolding or access equipment should be removed and the area left clear.
After a repair, it is worth checking the relevant area of the loft the next time there is heavy rain, to confirm the repair has addressed the source of the problem. If you can see daylight through a roof in loft from below, that is a sign worth raising before work starts so it can be dealt with at the same time.
