What should you do about a roof leak in Mountain Ash?
Landlords with flats or HMOs in Mountain Ash are generally expected to deal with leaks promptly once tenants report them. An emergency visit stops the water, and our written report and quote give you what you need to approve the permanent repair.
In and around Mountain Ash, flat roofs are typically found on terraced streets with flat-roofed rear kitchens and bathrooms, and on shops with flat-roofed rear stores below flats. 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.

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.
What's included?
- Damage recorded and explained before the team leaves
- Blocked outlets and gutters cleared where they're the cause
- Temporary weatherproofing as soon as a team is available
- 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.

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 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.
