Which flat roofs are common in Rhondda Cynon Taf?
Flat roofs in Rhondda Cynon Taf sit on shops with flat-roofed rear stores below flats, 1930s semis with flat-roofed garages and kitchen extensions and newer estates where the first extension roofs are now being replaced. Wales averages roughly 1,460 mm of rain a year, among the wettest in Britain, so we design for steady run-off: proper falls, clear outlets and upstands well above the finished roof. Approximate 1991–2020 regional averages based on Met Office data.
Building regulations in Wales
Welsh guidance is that most re-roofing needs building control approval, so it's worth checking whenever more than a quarter of a roof is replaced or repaired. Renovated roofs are upgraded to around 0.16 W/m²K where feasible, and new extension roofs are built to 0.13 W/m²K under the Welsh Approved Document L. In Rhondda Cynon Taf the application goes to Rhondda Cynon Taf County Borough Council. More on the rules.
What does a temporary weatherproofing visit involve?
A temporary visit stops the water getting in until a permanent repair can be made. It is not the finished repair.
Depending on the weather and the damage, the team may clear a blocked outlet or gutter that is backing water up, fix a heavy-duty temporary sheet over the damaged area, weight or secure lifted membrane and trims, or apply a temporary seal to a split or open lap. Where a rooflight or upstand is the cause, they make it as weathertight as they safely can.
Before they leave, the team will tell you what they found and what they did. They may also be able to give you an early view of whether the roof looks repairable or is due for replacement. That is followed by a written quote for the permanent work.
Should the roof be repaired or replaced after an emergency leak?
It depends on what the inspection finds once the roof is dry. A single storm-damaged area on a sound roof can usually be repaired. Widespread damage, wet insulation or a soft deck point towards replacement.
Emergencies tend to happen on roofs that were already near the end of their life. A storm lifts a tired seam, or a winter of frost opens cracks in old felt. We will give you a straight answer about which applies to your roof, and our repair or replace guide explains how to weigh it up.
Water that got in during the leak needs to dry out. Saturated insulation inside a roof doesn't insulate well and can keep the deck damp, so if it is soaked, it will need replacing as part of the permanent work.

Is a leaking ceiling dangerous?
It can be. A ceiling that is bulging or sagging may be holding water and could come down, so keep people out of the room beneath it. Water near light fittings or sockets is a serious electrical risk, so isolate that circuit if you can do so safely.
Can I put a tarpaulin on my flat roof myself?
We'd advise against it. Getting onto a flat roof in bad weather is dangerous, and many roofs and rooflights are fragile. Contain the water indoors and call us instead.
Can you repair a flat roof in the rain?
A temporary repair can often be made in wet weather if it is safe to work. A permanent repair needs a dry surface for the materials to bond, so it is done once conditions allow.
