Which flat roofs are common in Caerphilly?
Flat roofs in Caerphilly sit on terraced streets with flat-roofed rear kitchens and bathrooms, low-rise post-war blocks of flats and 1960s and 1970s link-detached houses with flat-roofed garages and porches. 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 Caerphilly the application goes to Caerphilly 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.

What causes a sudden flat roof leak?
Common causes are storm damage that lifts seams, edges or trims, outlets blocked by leaves so water backs up over upstands, and old felt cracking after a cold snap. Sometimes the cause is a wall or coping above the roof rather than the roof itself.
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.
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.
