Which flat roofs are common in County Antrim?
Flat roofs in County Antrim sit on newer estates where the first extension roofs are now being replaced, 1930s semis with flat-roofed garages and kitchen extensions and low-rise post-war blocks of flats. 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.
Building control in Northern Ireland
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. Technical Booklet F1 sets roof insulation at 0.18 W/m²K when a roof over a heated room is renovated or newly built, where feasible. In County Antrim the application goes to Lisburn and Castlereagh City Council, Antrim and Newtownabbey Borough Council, Mid and East Antrim Borough Council and 1 other council. More on the rules.
What does a temporary weatherproofing visit involve?
A temporary visit stops the water getting in until a permanent repair can be made. It is not the finished repair.
Depending on the weather and the damage, the team may clear a blocked outlet or gutter that is backing water up, fix a heavy-duty temporary sheet over the damaged area, weight or secure lifted membrane and trims, or apply a temporary seal to a split or open lap. Where a rooflight or upstand is the cause, they make it as weathertight as they safely can.
Before they leave, the team will tell you what they found and what they did. They may also be able to give you an early view of whether the roof looks repairable or is due for replacement. That is followed by a written quote for the permanent work.
How long does a temporary repair last?
A temporary repair is designed to hold for days or weeks, not years. It buys time for the roof to dry and for the permanent work to be planned.
Temporary sheeting can be lifted by high winds, and a cold-weather seal on a wet surface won't bond as well as a proper repair. We recommend booking the permanent repair or replacement promptly rather than relying on the temporary fix through a season. If the temporary work moves or the leak returns, call us again.
Once the permanent work is done, how long it lasts depends on the repair and on the rest of the roof. Our lifespan guide gives typical service lives for each roof system.

Because we would rather not promise a time we can't keep. Demand spikes after storms and safe working depends on the weather, so we send a team as soon as one is available and keep you updated.
What causes a sudden flat roof leak?
Common causes are storm damage that lifts seams, edges or trims, outlets blocked by leaves so water backs up over upstands, and old felt cracking after a cold snap. Sometimes the cause is a wall or coping above the roof rather than the roof itself.
Can you repair a flat roof in the rain?
A temporary repair can often be made in wet weather if it is safe to work. A permanent repair needs a dry surface for the materials to bond, so it is done once conditions allow.
