Which flat roofs are common in Isle of Anglesey?
Flat roofs in Isle of Anglesey sit on bungalows with flat-roofed side extensions and dormers, newer estates where the first extension roofs are now being replaced and lock-up garage blocks on estates. 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 Isle of Anglesey the application goes to Isle of Anglesey County Council. More on the rules.
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.
How quickly can someone come out?
We send a team for a temporary weatherproofing visit as soon as one is available. We don't promise a set response time, because demand jumps after storms and we would rather give you an honest answer on the phone than a figure we can't keep.
When you call, we ask a few questions about the roof and the leak so we can judge how urgent it is and what the team will need. Height matters: a single-storey garage or extension can usually be reached with ladders and edge protection, while a dormer or second-floor roof may need scaffold or a tower.
Safety comes before speed. In high winds, lightning or heavy rain, a team may not be able to work on the roof safely, and the visit may need to wait until conditions ease. Your best protection in the meantime is to contain the water indoors, as above.

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.
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.
Do you do emergency repairs for landlords and businesses?
Yes. We carry out emergency visits for landlords, managing agents and commercial owners as well as homeowners. Let us know who will give access and how to reach the roof when you call.
