What do block and HMO roofs in Donaghadee need?
Fire performance matters near boundaries and on occupied buildings in Donaghadee. 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.
Around Donaghadee, flat roofs are common on shops with flat-roofed rear stores below flats and on bungalows with flat-roofed side extensions and dormers. Northern Ireland averages roughly 1,150 mm of rain a year, spread over many wet days, so a roof that sheds water quickly to clear outlets lasts far longer than one that holds puddles.
How much does a block or HMO roof cost in Donaghadee?
For Donaghadee we use Northern Ireland rates: £13,700–£23,950 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 | £13,700–£23,950 |
| Commercial roof (100 m²), single-ply + insulation | £11,650–£19,150 |
Which roofing systems last longest on a block of flats?
Mastic asphalt, EPDM, single-ply and high-performance built-up felt all give long service lives on block roofs; the right choice depends on the deck, how the roof is used, the details and the whole-life cost.
- Mastic asphalt: 30–60 years with maintenance, common on concrete-decked blocks and walkways. See mastic asphalt roofing.
- EPDM: 25–50 years, laid in large sheets with few joins.
- Single-ply: 25–35+ years, quick to lay on larger roofs, with welded laps. See single-ply roofing.
- Built-up felt: 15–25 years for modern torch-on systems and longer for high-performance systems, robust where maintenance teams walk the roof.
- Liquid-applied: 10–25+ years by product, useful as an overlay on a sound roof with complex details.
The cheapest roof today is not always the cheapest over the life of the building. A longer-life system, with tapered insulation to cure ponding, can mean fewer reactive repairs and fewer rounds of consultation. These lives are indicative and assume good specification and regular maintenance.

Building control in Northern Ireland
In Northern Ireland, Technical Booklet F1 sets roof insulation at 0.18 W/m²K when a roof over a heated room is renovated or newly built, where that's feasible. The district council's building control should be contacted before work starts, and we prepare the details it asks for. More on the rules.
