Which flat roofs are common in Flintshire?

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 Flintshire, flat roofs are typically found on 1930s semis with flat-roofed garages and kitchen extensions, low-rise post-war blocks of flats 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 Flintshire?

Balconies and roof terraces

Settled, rocking or cracked paving is a common reason to re-waterproof a terrace in Flintshire. Slabs bedded directly on the membrane can damage it over time. Relaying them on adjustable pedestals protects the waterproofing and gives a level surface that drains underneath.

Green and sedum roofs

If you're replacing an old flat roof in Flintshire, it's worth deciding whether to add sedum at the same time. If the structure can take it, that is the ideal moment, because the waterproofing is new and the green layers won't need lifting for a long time.

Flats, HMOs and block roofs

Leaseholders in Flintshire 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.

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.
