Flats, HMOs and block roofs across Swansea

We replace and repair flat roofs on blocks of flats, converted houses and HMOs across Swansea, for freeholders, landlords, managing agents and resident management companies. Replacement surveys are free, and every quote is itemised so it can be shared with leaseholders. Work is phased around residents, using long-life systems such as single-ply, mastic asphalt, EPDM and built-up felt.

Which flat roofs are common in Swansea?

Flat roofs in Swansea sit on shops with flat-roofed rear stores below flats, 1960s and 1970s link-detached houses with flat-roofed garages and porches and bungalows with flat-roofed side extensions and dormers. 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.

Building regulations in Wales

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. Renovated roofs are upgraded to around 0.16 W/m²K where feasible, and new extension roofs are built to 0.13 W/m²K under the Welsh Approved Document L. In Swansea the application goes to Swansea Council. More on the rules.

How do you manage access and residents during the work?

We agree an access and communication plan with the agent or freeholder before the scaffold goes up, so residents know what is happening and when.

That usually covers notices in the common parts and letters to each flat, scaffold and skip positions, keeping entrances, escape routes and bin stores clear, working hours, securing the scaffold out of hours, and a named contact for questions. If we need to look at a ceiling inside a top-floor flat, we arrange access through the agent or landlord.

Occupied blocks are re-roofed in phases, with each section watertight before the team leaves site, which also lets a larger roof be spread over more than one service charge year. Hot works near windows, vents and escape routes are tightly controlled, or avoided altogether with cold-applied systems.

How does Section 20 consultation affect roof works?

In England and Wales, if leaseholders pay for roof works through the service charge and any one leaseholder's share will be over the statutory threshold, the freeholder or managing agent must consult them under Section 20 of the Landlord and Tenant Act 1985 before the work is contracted.

The consultation is run by the freeholder or agent, not by us. It usually involves a notice of intention and then estimates shared with leaseholders, each stage with time for comments, and missing a step can limit what can be recovered through the service charge. Take advice from your agent or a specialist adviser if you are unsure; we don't give legal advice.

What we provide is an itemised written quote that is easy to share and compare: system and build-up, roof area, scaffold and access, insulation, outlets, upstands and trims, waste disposal, provisional sums for hidden defects such as deck repairs, and VAT shown clearly. We can price more than one system on the same scope, so leaseholders are comparing like with like.

What if a top-floor flat is leaking before the roof is replaced?

We can attend for emergency temporary weatherproofing as soon as a team is available, guide £170–£410. That protects the flat while the permanent work is agreed.
