What flat roof work do we do in Larne?
Flat roof repairs
Buying or selling a property in Larne with a tired flat roof? A surveyor's report may flag damp, blistering or ponding. A targeted repair can deal with an isolated defect, and where the roof is near the end of its life we will explain that clearly so the cost can be planned.
Warm roof insulation upgrades
Landlords with flats and HMOs in Larne sometimes hear from tenants about cold top-floor rooms and black mould on ceilings. A warm roof upgrade during re-roofing tackles both the heat loss and the condensation behind the mould, and helps keep the roof timbers dry.
Torch-on felt roofing
Torch-on felt is widely specified for blocks of flats and HMOs, in Larne as elsewhere, because the system is well understood, widely repairable and governed by a British Standard code of practice. Three-layer builds with insulation are common on larger, multi-occupied roofs.

What flat roofs are typical in and around Larne?
In a town like Larne flat roofs are mostly on lock-up garage blocks on estates and shops with flat-roofed rear stores below flats. Rain and wind decide how a flat roof is detailed. 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. Approximate 1991–2020 regional averages based on Met Office data.
Who approves flat roof work in Larne?
Where approval is needed it goes to Mid and East Antrim Borough Council building control. In Northern Ireland, renovating or replacing a roof over a heated room usually means meeting Technical Booklet F1, and building control should be contacted before work starts. How the rules work.
