What do block and HMO roofs in Clevedon need?
Roof works on a block in Clevedon affect many households at once. We agree notices, scaffold positions, working hours and a named contact with the agent or freeholder before we start, so residents know what is happening, when it will happen and who to ask if they have a question.
Around Clevedon, flat roofs are common on terraced streets with flat-roofed rear kitchens and bathrooms and on lock-up garage blocks on estates. The South West averages roughly 1,260 mm of rain a year and many roofs face wind off the Atlantic, so we specify fixings and edge details for wind uplift as well as drainage.
How much does a block or HMO roof cost in Clevedon?
For Clevedon we use South West rates: £16,000–£28,000 is the guide for a 150 m² block-of-flats roof in felt with insulation and scaffold, VAT included. 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 | £16,000–£28,000 |
| Commercial roof (100 m²), single-ply + insulation | £13,650–£22,450 |
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.

- Free survey and fixed, itemised written quote

Building regulations in England
Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.

How much does a block or HMO roof cost in Clevedon?
£16,000–£28,000 for a 150 m² block-of-flats roof in felt with insulation and scaffold, at South West guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
Do residents need to move out during a re-roof?
No. Block roofs are normally replaced with residents in place, and if we need to check a ceiling inside a top-floor flat, access is arranged through the agent or landlord.
Can a block roof be replaced in phases?
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.
