Roof Timbers on Cardiff Properties

The battens are the horizontal strips the covering is fixed to and the rafters and purlins are the structure under them, and on a roof sharing its valleys and its stacks both are frequently still the original timber. On these bay-fronted slate terraces the battens are frequently original, and a covering can only be as secure as the timber holding it.
What This Covers
- Damaged battens
- Local timber defects
- Supporting roof structure
- Water ingress connected with the affected detail
- Localised weathering or damage requiring repair
Rot and Where It Starts
Timber rots where it stays wet, and with driven rain off the Channel the wet is supplied continuously once anything above has failed. On a roof sharing its valleys and its stacks the usual sequence is a slipped covering or a failed flashing, then a season of water onto one area, then soft batten and a rafter end going at the eaves.
What You Can See From Inside

A torch in the loft on a wet day tells you a great deal on these bay-fronted slate terraces — staining, damp timber, daylight where there should not be any. Where access is tight for scaffold, the external work follows once we know from inside where to look.
Replacing Sound for Rotten
Battens are replaced by lifting the covering over the affected area, which on a roof sharing its valleys and its stacks means the repair is always a little larger than the rot. Rafter ends can be spliced or sistered where the damage is local, and because a defect here is often shared with next door, we would rather open up far enough to find sound timber than close it over something soft.

Roof Timber & Batten Repairs in Cardiff — Common Questions
What are common signs that I may need roof timber & batten repairs in Cardiff?
The battens are the horizontal strips the covering is fixed to and the rafters and purlins are the structure under them, and on these bay-fronted slate terraces both are frequently still the original timber. On a roof sharing its valleys and its stacks the usual sequence is a slipped covering or a failed flashing, then a season of water onto one area, then soft batten and a rafter end going at the eaves.
Can a small defect cause an internal leak?
Yes. The kind of defect behind roof timber & batten repairs lets water into the structure on these bay-fronted slate terraces, and it can travel a long way before it shows on a ceiling. That is why the source of a roof timber & batten repairs problem is traced rather than guessed at from the mark inside.
Will the whole roof need replacing?
Usually not. Roof timber & batten repairs is repair work, and on a roof sharing its valleys and its stacks the covering around the defect is generally sound — whether a repair is the right answer depends on how far the deterioration has gone beyond the part you can see.
Can you inspect the problem before recommending work?
Yes, always. Given a defect here is often shared with next door, a roof timber & batten repairs job on these bay-fronted slate terraces is looked at before anything is recommended, and you get told what was actually found rather than a figure guessed from the pavement.

What does a repair like this cost?
Two things set the figure for roof timber & batten repairs: how far the defect has actually gone, which needs somebody to look at it, and the access. With access here restricted by controlled parking and narrow frontages, that second one moves the price of roof timber & batten repairs more than the materials do, and it is why a figure over the phone is a guess.
Can you look at other things while you are there?
Yes, and it is worth it — given a defect here is often shared with next door, safe access to the roof is most of what a visit costs, so anything else wanting attention is far cheaper dealt with on the same day as the roof timber & batten repairs.
