Which flat roofs are common in Cardiff?
Flat roofs in Cardiff sit on low-rise post-war blocks of flats, bungalows with flat-roofed side extensions and dormers 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 Cardiff the application goes to Cardiff Council. More on the rules.
How long does a temporary repair last?
A temporary repair is designed to hold for days or weeks, not years. It buys time for the roof to dry and for the permanent work to be planned.
Temporary sheeting can be lifted by high winds, and a cold-weather seal on a wet surface won't bond as well as a proper repair. We recommend booking the permanent repair or replacement promptly rather than relying on the temporary fix through a season. If the temporary work moves or the leak returns, call us again.
Once the permanent work is done, how long it lasts depends on the repair and on the rest of the roof. Our lifespan guide gives typical service lives for each roof system.
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.

How much does an emergency leak repair cost in Cardiff?
£170–£410 for an emergency temporary weatherproofing visit, at Wales guide rates including VAT. We confirm the price once we've traced the leak or seen the damage.
Which council handles building control for a flat roof in Cardiff?
It depends on where the roof is: in Cardiff that's Cardiff Council. 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. We confirm which applies at the survey.
Why can't you give me an exact arrival time?
Because we would rather not promise a time we can't keep. Demand spikes after storms and safe working depends on the weather, so we send a team as soon as one is available and keep you updated.
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.
Will my home insurance cover an emergency roof repair?
It depends on your policy and the cause. Storm damage is often covered, while wear and tear usually isn't, so check with your insurer. Notes made at the time, plus our written report, can help with a claim.
