Slate Roofs in Barry

Welsh slate outlasts almost everything else on a roof, and on a post-war estate covering the slate itself is very often still perfectly serviceable when the roof starts leaking. What fails first is the nail and after that the batten, which is why on these concrete interlocking tile roofs a hundred-year-old roof usually needs re-fixing rather than re-slating.
What This Covers
- Broken slates
- Slipped slates
- Slate roof leaks
- Water ingress connected with the affected detail
- Localised weathering or damage requiring repair
Nail Sickness
The term for it is nail sickness, and on a post-war estate covering it is the single commonest reason for repair. With salt on the prevailing south-westerly the nails corrode from above and the batten softens from below, and slates begin to let go in ones and twos across the whole slope rather than in one place.
Working on a Slate Roof

Slate is brittle and cannot be walked on, so work on these concrete interlocking tile roofs is done off ladders, roof ladders or a scaffold rather than from the covering itself. Where access is level with reasonable street access, that is the part of a slate job that takes the planning, and it is why a slate repair costs more than the same repair on tile.
Tingles, Re-Fixing and Reclaimed Slate
An individual slipped slate on a post-war estate covering is re-fixed with a tingle — a copper or lead strip hooked over the batten — because the original nail holes cannot be reached without lifting the courses above. Where a slate is broken, a reclaimed slate of matching size and thickness is used, and on roofs like these the match matters, particularly where salt air is hard on fixings here.

Slate Roof Repairs in Barry — Common Questions
What are common signs that I may need slate roof repairs in Barry?
Welsh slate outlasts almost everything else on a roof, and on these concrete interlocking tile roofs the slate itself is very often still perfectly serviceable when the roof starts leaking. With gusts that come several times a winter the nails corrode from above and the batten softens from below, and slates begin to let go in ones and twos across the whole slope rather than in one place.
Can a small defect cause an internal leak?
Yes. The kind of defect behind slate roof repairs lets water into the structure on a post-war estate covering, and it can travel a long way before it shows on a ceiling. That is why the source of a slate roof repairs problem is traced rather than guessed at from the mark inside.
Will the whole roof need replacing?
Usually not. Slate roof repairs is repair work, and on these concrete interlocking tile roofs 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 salt air is hard on fixings here, a slate roof repairs job on a post-war estate covering 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 slate roof repairs: how far the defect has actually gone, which needs somebody to look at it, and the access. With access here open along the estate frontages, that second one moves the price of slate roof 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 salt air is hard on fixings here, 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 slate roof repairs.
