Felt Roofs on Pontypridd Properties

Felt is the oldest flat roofing system still in common use and there is a great deal of it on a roof in a continuous ridge line, mostly over garages, extensions and outbuildings. Modern torch-on felt is a serious material and the thin mineral felt on a 1970s garage is not, and on these stepped hillside slate terraces both are still in service side by side.
What This Covers
- Torn felt
- Blistering felt
- Felt roof leaks
- Water ingress connected with the affected detail
- Localised weathering or damage requiring repair
How Felt Fails
Felt becomes brittle as the bitumen loses its oils, and with rain arriving off the hills on both sides the wet-dry-frost cycling accelerates it. On a roof in a continuous ridge line the pattern is cracking along the laps first, then blistering where moisture is trapped beneath, then splitting at the upstands where the material has to bend.
Assessing a Felt Roof

Felt has to be walked and looked at closely rather than viewed from a window, and where access is as steep as residential streets get that is the part of the job worth planning. With access hard enough that getting a ladder up is a job in itself, getting onto a garage or extension roof on these stepped hillside slate terraces is usually straightforward, which is one thing in its favour.
Repair or Re-Cover
A torch-on patch over a clean sound substrate is a real repair on a roof in a continuous ridge line and will last. Patching brittle felt that has reached the end of its life is not — the patch holds and the felt next to it splits instead, and with high rainfall where the valleys meet that happens by the following winter. We will tell you which of the two you have, because on these stepped hillside slate terraces that answer changes what is worth spending.

Felt is the oldest flat roofing system still in common use and there is a great deal of it on a roof in a continuous ridge line, mostly over garages, extensions and outbuildings. On these stepped hillside slate terraces the pattern is cracking along the laps first, then blistering where moisture is trapped beneath, then splitting at the upstands where the material has to bend.
Can a small defect cause an internal leak?
Yes. The kind of defect behind felt roof repairs lets water into the structure on a roof in a continuous ridge line, and it can travel a long way before it shows on a ceiling. That is why the source of a felt roof repairs problem is traced rather than guessed at from the mark inside.
Will the whole roof need replacing?
Usually not. Felt roof repairs is repair work, and on these stepped hillside slate terraces 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.

What does a repair like this cost?
Two things set the figure for felt roof repairs: how far the defect has actually gone, which needs somebody to look at it, and the access. With access here as steep as residential streets get, that second one moves the price of felt 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 access sets the price here more than the repair does, 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 felt roof repairs.
