Flat roofing contractors in Conwy

A warm roof upgrade in Conwy adds height, so we check the levels at doors, sills, walls and rooflights at the free survey. Upstands are raised to keep about 150 mm above the finished roof, trims are reset, and where height is tight, we look at thinner insulation or other options. Looking for liquid roofing in Conwy? We use cold-applied systems for roofs with awkward details, balconies and walkways, and for overlays that avoid a full strip-out. Where insulation is needed over a heated room, we will tell you if a strip and warm-roof build-up is the better route, and handle any approval.

Which flat roofs are common in Conwy?

Local weather shapes the specification. 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. Across Conwy, flat roofs are typically found on bungalows with flat-roofed side extensions and dormers, 1960s and 1970s link-detached houses with flat-roofed garages and porches and newer estates where the first extension roofs are now being replaced. Approximate 1991–2020 regional averages based on Met Office data.

Which flat roof jobs do we take on in Conwy?

Dormer roofs

If your dormer in Conwy was added years ago with a basic felt roof and little insulation, it will tend to fail at the edges first, and they leave the loft room cold in winter and hot in summer. A warm-roof replacement deals with both problems at once.

Flats, HMOs and block roofs

Leaseholders in Conwy want to see where their money goes. Our itemised quotes show each element of the job separately, including scaffold, insulation and provisional sums for hidden defects, which makes them easier to share and compare when the freeholder or agent is consulting on the work.

Torch-on felt roofing

Torch-on is a good fit in Conwy when the budget matters but quality cannot slip. Modern polyester-reinforced membranes typically last 15 to 25 years, high-performance systems longer, and manufacturer material guarantees are available on many specified systems, registered where the system allows.

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.
