What do block and HMO roofs in Denbigh need?

Fire performance matters near boundaries and on occupied buildings in Denbigh. We check the external fire classification of the whole roof build-up, not just the membrane, control or avoid hot works near escape routes and windows, and keep fire-stopping details intact where the roof crosses a separating wall.

Denbigh's flat roofs are mostly on lock-up garage blocks on estates, with plenty on newer estates where the first extension roofs are now being replaced too. 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.

How much does a block or HMO roof cost in Denbigh?

At Wales guide rates, a 150 m² block-of-flats roof in felt with insulation and scaffold comes to £14,300–£25,000 including VAT. The fixed price comes after a free survey for new and replacement roofs.

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's included?

  • Quotes laid out to support leaseholder consultation
  • Written workmanship guarantee, with manufacturer guarantees registered where the system allows
  • Free survey and fixed, itemised written quote
  • Resident notices, access planning and phased 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.
