Which flat roofs are common in Isle of Anglesey?

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 Isle of Anglesey, 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 low-rise post-war blocks of flats. Approximate 1991–2020 regional averages based on Met Office data.

Which flat roof jobs do we take on in Isle of Anglesey?

Commercial flat roofing

Businesses in Isle of Anglesey need a roofing contractor who arrives with a plan, not just a price. We put the system, build-up, phasing, access and payment terms in a fixed written quote, and keep each section of the roof watertight before the team leaves site, so trading is not put at risk.

Green and sedum roofs

In a place like Isle of Anglesey, many people look out over a flat extension or garage roof from upstairs. Grey felt or rubber isn't much of a view, and a sedum roof turns it into something green that changes colour through the seasons and flowers in summer.

Liquid-applied roofing

If a flat roof in Isle of Anglesey is ageing but still dry, firmly bonded and on a sound deck, a reinforced liquid system can be applied over it. That avoids the cost and mess of a full strip-out, provided the moisture and adhesion checks at survey show the existing roof is fit to build on.

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.
