Repair is right when the problem is local and the structure is sound. Replacement makes sense when failures are widespread. The skill is telling which one your roof needs.
Old roofs rarely give a simple answer. On Clifton's Georgian and Victorian terraces and villas, slates, lead and timbers can all be at different stages of wear. A fair judgement comes from looking at the whole roof, not just the patch that happens to be leaking this winter.
What points towards repair
Repair suits a roof whose main structure is sound. A few slipped slates, a split in a lead valley, a loose ridge or failing pointing around a stack can be put right without disturbing the rest. If the battens are firm, the felt is in reasonable order and the problems are local, repair is usually the sensible and honest answer.
On older terraces, much of the roof's value lies in details worth saving: sound slates can often be reused, and lead can be renewed in sections. We say what is worth keeping, not just what is easiest to strip off.
What points towards replacement
Replacement comes into view when failure is widespread. Slates slipping across the slope, battens that are soft, felt that has perished and repeated repairs in the same area all suggest the roof as a whole has reached the end of its working life. Patching then becomes a series of call-outs, each fixing one symptom.
- Many slates slipping or cracking across several slopes
- Soft or rotten battens seen from the loft
- Daylight and damp across wide areas of the roof
- Repairs that keep failing in new places
What we look at
We look at the covering, the ridge and hips, the lead work, the chimney stacks, the gutters and the loft side. The loft tells us about felt, timbers and ventilation. We also consider the roof's shape: steep slopes and parapets make repeated access disruptive, which affects the sums when repairs keep returning.
Scaffold is a real consideration on a tall house, so a repair that needs access every winter is not always the economical choice. We weigh up how often we would need to return. If we think two or three more winters of repairs will cost you more in disruption than renewing, we say so plainly.
A mixed approach is possible
It is not always all or nothing. A roof may have one slope in poor condition and the rest sound, and re-roofing that one slope while repairing the others can be sensible. We describe options clearly, say what is urgent and what can wait, and explain the likely result of each so you can choose.
- Repair now, plan replacement later
- Re-roof the worst slope only
- Renew lead and stacks while the covering stays
- Full replacement of the whole roof
What to ask any roofer
Ask what evidence supports the advice, and to see photographs from the roof and loft. Ask what is included in writing and what happens if hidden damage appears. Be wary of anyone who insists on replacement without showing why. Some work may need planning or Building Regulations checks — we advise before work starts.
Frequently Asked Questions
How do I know my roof is beyond repair?
Signs include widespread slipping, soft battens, perished felt and repairs that keep failing. A proper inspection of both the roof and the loft shows whether the problems are local or general. We show you photographs from the roof and the loft so you can see the evidence.
Does a leak mean I need a new roof?
Not necessarily. Many leaks come from a single detail such as a valley, flashing or stack. We trace the source and tell you whether a repair will do the job. If a leak does come from a single detail, we will say so and repair just that.
Can part of a roof be replaced?
Yes, where one slope or section is failing and the rest is sound. We look at how the sections join and describe the work clearly. It can be a sensible middle route. We explain how the new and old sections will join before agreeing anything.
