What flat roof work do we do in Monmouth?
Flat roof replacement
Selling or letting a property in Monmouth can also prompt a replacement. A buyer's surveyor will usually flag a flat roof near the end of its life, and a recent replacement with written workmanship and material guarantees answers that question before it turns into a negotiation point.
Dormer roofs
A dormer roof that has been patched several times in Monmouth often has layers of old repairs that hide the real fault. Stripping back to the deck shows what has been going on, and lets the team rebuild the back-edge abutment properly rather than sealing over it again.
Warm roof insulation upgrades
Kitchen extensions in Monmouth, as elsewhere, produce a lot of moisture from cooking. Under a cold flat roof, that moisture can condense on the deck. A warm roof keeps the deck warm and puts a vapour control layer in the way, which lowers the risk considerably.

What flat roofs are typical in and around Monmouth?
In a town like Monmouth flat roofs are mostly on bungalows with flat-roofed side extensions and dormers and 1960s and 1970s link-detached houses with flat-roofed garages and porches. 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 Monmouth?
Where approval is needed it goes to Monmouthshire County Council building control, or a registered building control approver. 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. How the rules work.
