What do block and HMO roofs in Lisburn need?
A block roof in Lisburn 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.
Around Lisburn, flat roofs are common on bungalows with flat-roofed side extensions and dormers and on 1960s and 1970s link-detached houses with flat-roofed garages and porches. 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 Lisburn?
Guide price in Lisburn: £13,700–£23,950 for a 150 m² block-of-flats roof in felt with insulation and scaffold, including VAT at Northern Ireland 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 | £13,700–£23,950 |
| Commercial roof (100 m²), single-ply + insulation | £11,650–£19,150 |
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?

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.
