What do block and HMO roofs in Gorseinon need?
Service charge budgets for blocks in Gorseinon do not always stretch to a whole roof at once. We can phase a re-roof over more than one budget year, pricing each phase separately in writing and keeping every section watertight in between, so the building stays protected while the cost is spread.
Gorseinon's flat roofs are mostly on terraced streets with flat-roofed rear kitchens and bathrooms, with plenty on bungalows with flat-roofed side extensions and dormers 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 Gorseinon?
Guide price in Gorseinon: £14,300–£25,000 for a 150 m² block-of-flats roof in felt with insulation and scaffold, including VAT at Wales rates. The fixed price comes after a free survey for new and replacement roofs.
| Job | Guide price inc VAT |
|---|---|
| Block of flats (150 m²), felt + insulation + scaffold | £14,300–£25,000 |
| Commercial roof (100 m²), single-ply + insulation | £12,150–£20,050 |
Do fire and insulation rules affect block roofs?
Yes. Where a roof is close to a boundary, building regulations limit which coverings can be used, and the build-up should carry a suitable external fire classification such as BROOF(t4); in England this is covered by Approved Document B.
BROOF(t4) applies to a tested build-up, so we check that the manufacturer's classification covers the deck, insulation and membrane actually being installed, not just the membrane name. Where the roof crosses a separating or compartment wall, the fire-stopping detail is kept intact.
Re-covering more than half of a roof over heated flats usually triggers the thermal element rules, so the insulation is upgraded towards the renovation U-value where feasible: 0.16 W/m²K for dwellings in England and Wales. We handle building control where it is needed. See building regulations and warm vs cold roofs.

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.

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

Yes. Larger roofs can be split into sections over one or more budget years, with each phase priced separately and each section left watertight before the team leaves site.
