What do block and HMO roofs in Penzance need?
A block roof in Penzance is a long-term asset, so we talk about whole-life cost as well as the price today. A longer-life system with corrected falls can mean fewer reactive repairs and fewer rounds of consultation over the years, and the survey explains the options in plain terms.
Penzance's flat roofs are mostly on low-rise post-war blocks of flats, with plenty on lock-up garage blocks on estates too. 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 Penzance?
At South West guide rates, a 150 m² block-of-flats roof in felt with insulation and scaffold comes to £16,000–£28,000 including VAT. 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 |
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.
What's included?
- Resident notices, access planning and phased work
- Long-life systems: mastic asphalt, EPDM, single-ply and built-up felt
- Written workmanship guarantee, with manufacturer guarantees registered where the system allows
- Building control and insulation upgrades handled where needed
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 Penzance?
£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.
Can you quote for more than one roofing system?
Yes. We can price two or more systems on the same scope, for example built-up felt and single-ply, so leaseholders and the freeholder can compare cost against expected service life.
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.
