On an older Brentry semi, the choice between patching and starting again turns on what lies under the tiles, not just how they look from the street.
Roofs on the inter-war and post-war semis and terraces of Brentry have often seen a lot of weather and a few earlier repairs. Deciding whether to mend or renew is not about the age of the house. It comes down to the state of the tiles, the timbers and the layers under them, and how often the roof has been patched already.
Why age alone does not decide it
A well-built roof can serve a long time, and a poor one can fail early. Some older roofs only need a handful of tiles and a ridge re-bedded. Others have crumbling tiles, tired timbers and a repair history that is clearly running out of road. We judge each roof on its present condition rather than on how old the house is.
The loft tells most of the story
Inside, we look for daylight, stained or torn felt, damp rafters and battens that crumble when pressed. Old roofs of this era sometimes have no underlay at all, or a very thin one, which changes the picture. Water often travels along timbers before showing on a ceiling, so one patch indoors may point to several faults above.
We take notes and photographs so you can see what we mean rather than take it on trust. Pictures from the loft often make the decision easier, because the state of the felt, rafters and battens is plain to see, and you can show them to anyone else you ask.
- Underlay missing, torn or brittle
- Battens soft, split or darkened with damp
- Tiles that flake, crumble or lift easily
- Repeated stains in different rooms
When repairs are sensible
Where the tiles and timbers are largely sound, targeted repair is the honest answer: replace broken tiles, re-bed the ridge, renew a lead flashing, fix the verges and clear the gutters. A tidy repair can keep an older roof dry for a good while, and we will say what to expect rather than promise too much.
Typical repair jobs on semis like these include slipped tiles above a porch, a failed hip or ridge, lead around a chimney and edge tiles at a gable end. Each can be done on its own and then watched, which suits owners who want to spread the work.
When replacement is wiser
If tiles are failing across whole slopes, battens are rotten and there is little or no underlay, repairing piece by piece costs more over time and still leaves leaks. A re-roof with new battens, underlay and proper edge details solves the cause, and gives a chance to add vents, dry verge units and fresh flashings in one go.
How to decide with confidence
Ask us to explain the choice in plain words and in writing, with what each option covers and what it leaves out. A good roofer should say what is urgent and what can wait. If any work may need planning or Building Regulations checks, we advise before work starts.
Frequently Asked Questions
Is it worth repairing a roof that is already leaking in several places?
Sometimes, but several leaks often mean the underlay or battens are failing generally. We check before suggesting repairs, since patching a roof that is giving up all over can be money spent for little return.
Can the tiles be reused on a re-roof?
Sometimes, if they are sound and a consistent type. Many are cracked or worn and are better replaced. We sort and test them, and explain what can go back and what cannot, so you know what is being reused.
Do I need to be at home during an inspection?
Not always. We need loft access and a look from outside, and many owners arrange that in advance. We then explain what we found, with photographs, so you can talk through the options properly without being rushed into anything.
