Flat Roofs in Maesteg

Most flat roofs on a roof still on Victorian timber are over an extension, a garage, a dormer or a bay, and almost none of them are actually flat — they are laid to a shallow fall. When that fall is lost the water stops leaving, and under wind running straight onto the ridge line a flat roof that ponds is a flat roof on a clock.
What This Covers
- Flat roof leaks
- Surface splits
- Failed detailing
- Water ingress connected with the affected detail
- Localised weathering or damage requiring repair
What Kills Them Here
With heavy rainfall down the Llynfi, a flat roof spends a great deal of its life wet, and standing water finds every lap and upstand. On these tight Llynfi valley rows the failures concentrate at the edges, the upstands and around anything penetrating the deck rather than in the middle of the field.
Finding the Entry Point

A flat roof leak is harder to trace than a pitched one because water spreads across the deck rather than running down it, and on a roof still on Victorian timber the internal mark can be well away from the defect. Where access is narrow and stepped on steep ground, getting properly onto the roof to look is the first thing that has to happen.
Patch, Overlay or Replace
An isolated split in an otherwise sound covering is a genuine patch repair, and on these tight Llynfi valley rows that is frequently all that is needed. Where the covering has failed generally, or the deck beneath it is soft, patching is money spent twice — and with wind running straight onto the ridge line a soft deck does not dry out and does not recover.

Flat Roof Repairs in Maesteg — Common Questions
What are common signs that I may need flat roof repairs in Maesteg?
Most flat roofs on a roof still on Victorian timber are over an extension, a garage, a dormer or a bay, and almost none of them are actually flat — they are laid to a shallow fall. On these tight Llynfi valley rows the failures concentrate at the edges, the upstands and around anything penetrating the deck rather than in the middle of the field.
Can a small defect cause an internal leak?
Yes. The kind of defect behind flat roof repairs lets water into the structure on a roof still on Victorian timber, and it can travel a long way before it shows on a ceiling. That is why the source of a flat roof repairs problem is traced rather than guessed at from the mark inside.
Will the whole roof need replacing?
Usually not. Flat roof repairs is repair work, and on these tight Llynfi valley rows 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 the ridge line takes the full run of the wind, a flat roof repairs job on a roof still on Victorian timber 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 flat roof repairs: how far the defect has actually gone, which needs somebody to look at it, and the access. With access here constrained by narrow stepped streets with no rear access, that second one moves the price of flat 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 the ridge line takes the full run of the wind, 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 flat roof repairs.
