When is a flat roof survey worth it in Carrickfergus?
Flat roofs in Carrickfergus hide their problems well. A covering can look fine while the insulation beneath it is wet or the deck is softening. A survey with moisture readings and core samples shows what's happening under the surface before it reaches the ceiling.
Around Carrickfergus, flat roofs are common on 1930s semis with flat-roofed garages and kitchen extensions and on shops with flat-roofed rear stores below 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.
How much does a flat roof survey cost in Carrickfergus?
At Northern Ireland guide rates, a condition survey and leak investigation comes to £130–£260 including VAT. We confirm the price once we've traced the leak or seen the damage.

How do you find where a flat roof is leaking?
By working from the evidence inside back to the likely entry points outside, then confirming the path with moisture readings and, where needed, small test openings.
We start indoors, looking at where the staining is, when it appears and whether it follows rain, wind from one direction or cold weather. Then, on the roof, we check the details where most leaks start: upstands and flashings, laps and seams, outlets, gutters, edge trims, rooflight kerbs and anything that passes through the covering. Walls, copings and cavity trays above the roof are checked too, because water getting in behind an upstand can look like a roof leak.
A moisture meter shows where the covering, or the material beneath it, is holding water, and readings across the roof help map how far the wet has spread. Meter readings are a guide, not proof, so where they suggest a problem we may take a core sample: a small cut through the covering and insulation to see what is underneath and whether the deck is sound. The opening is sealed again with compatible material before we leave.
Condensation can also look like a leak, especially in older cold roofs without adequate ventilation, and the survey considers that possibility too. The flat roof leaks guide explains the common causes.

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.
