What should you do about a roof leak in Chepstow?
Leaves and debris build up in outlets and gutters on flat roofs around Chepstow, especially under trees. A blocked outlet can turn a normal rainstorm into a flood over the upstands. Clearing it is often part of the emergency visit, and the permanent fix looks at why it blocked.
In a town like Chepstow, flat roofs are commonly found on newer estates where the first extension roofs are now being replaced or 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.

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.
What's included?
- Written quote for the permanent repair or replacement

Building regulations in Wales
The Welsh Approved Document L applies. Renovating more than half of a roof over a heated room means upgrading it to around 0.16 W/m²K where feasible, and new extension roofs are built to 0.13 W/m²K. Welsh Government guidance is that most re-roofing needs building control approval, so check whenever more than a quarter of a roof is replaced or repaired. We deal with the application as part of the job. More on the rules.

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.
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.
