Neither answer is right for every roof. Repair makes sense when the problems are local and the structure is sound; replacement makes sense when failure is widespread. Here is how we judge Montpelier's older roofs.
On an old roof, the question is not how old it is but how it is failing. A handful of slipped tiles is a repair. A roof that leaks in several places, with tired battens and felt, is heading for replacement. Montpelier's Victorian roofs have often been patched for generations, so we look at the whole picture.
Where repair is the sensible answer
If the damage is local and the main structure is sound, repair is usually the right call. Slipped or cracked tiles, a split valley, lifted ridge bedding or a worn flashing round a chimney can all be dealt with without touching the rest. Repairs buy time at modest effort, provided the roof is otherwise dry and the timbers are solid.
A good repair also stops the cause, not only the symptom, for example by renewing a flashing rather than smearing sealant over it, so the same fault does not return after the next storm. Where the problem is simply one worn detail, there is rarely a reason to go further than renewing that detail properly and leaving the rest of the roof in place.
Signs that patching is running out
When the same roof needs attention repeatedly, a pattern is emerging. Widespread slipped tiles, brittle slates, sagging rafters, a loft full of daylight and stained or perished felt show the covering has had its time. Another repair then fixes one spot while the next fails.
- Leaks in several different places
- Many cracked, flaking or slipping tiles
- Rotted battens or damp rafters in the loft
- Repeat repairs to the same areas
What a closer look tells us
We look at the covering, the felt and battens, the ridge and hips, the flashings, the chimneys and the structure underneath. On tall Victorian houses we note where bays, chimneys and valleys concentrate the water, since those areas fail first. This whole-roof view lets us explain what is urgent, what is minor and what can wait.
Roofs in this area often carry earlier repairs of different ages and materials, which tells us how the roof has been looked after and where the weak spots are likely to be. That is the part a quick look from the pavement cannot give you.
Mixed answers are common
The best answer is often partial. One slope that has failed may be re-covered while the others are repaired, or a valley and chimney can be rebuilt without disturbing the rest. In flats with a shared roof, staging the work by section can make it easier for everyone involved to agree and plan.
Where a roof is shared between several flats, the work can often be agreed section by section, starting with whatever is letting water in right now. Doing it in stages also lets you spread the work sensibly. Staging also lets you spread the work sensibly across time and between the people involved.
Making the decision with us
We explain what we found, what a repair will achieve, what it will not and what replacement involves. We do not recommend a new roof when a repair will do, nor patch a roof that is past it. You then decide with the facts in front of you, whether that is doing the urgent items now or planning a larger job. Replacement may need planning or Building Regulations checks, and we advise before work starts.
Frequently Asked Questions
How do I know whether my roof is past repair?
Repeated leaks, widespread cracked or slipping coverings and damp rafters or battens point towards replacement. A roofer should show you the evidence so you can see the same signs. If you cannot see it from the ground, ask for photographs.
Is a repair just putting off the inevitable?
Sometimes, but not always. A repair on a sound roof can give many more seasons of use. On a roof that is failing everywhere, it buys little, and we say so honestly. That honest view is part of the job.
Can part of a roof be replaced?
Yes. One slope, a valley or a section around a chimney can be renewed on its own where the rest is sound. We check how the new section ties in so the junctions stay watertight.
