What flat roof work do we do in Treorchy?
Flat roof replacement
A mineral felt roof laid decades ago may still look intact from the ground in Treorchy, yet have lost its chippings, cracked at the laps and pulled away at the upstands. Those faults let water track under the covering, so by the time a ceiling stain appears, the deck has often been wet for some time.
Garage roofs
Garage roofs in Treorchy are often replaced when the deck gives way. Chipboard decks swell and soften once they get wet, and you may see sagging between joists or feel the roof flex underfoot. Replacing the deck and covering together is usually more economical than repeated repairs.
Commercial flat roofing
When a roof over heated space in Treorchy is replaced, insulation rules usually apply. We design the warm-roof build-up towards the required standard where that is feasible and handle building control where it is needed, so the work is signed off properly and the building is better insulated afterwards.

What flat roofs are typical in and around Treorchy?
In a town like Treorchy flat roofs are mostly on terraced streets with flat-roofed rear kitchens and bathrooms and newer estates where the first extension roofs are now being replaced. Rain and wind decide how a flat roof is detailed. 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.
Who approves flat roof work in Treorchy?
Where approval is needed it goes to Rhondda Cynon Taf County Borough Council building control, or a registered building control approver.
