When is a flat roof survey worth it in Colwyn Bay?
Older extensions and garages in Colwyn Bay frequently have felt roofs that have been patched several times. Before paying for another repair, many owners want to know whether the roof has much life left. That is exactly the question a condition survey answers.
In a town like Colwyn Bay, flat roofs are commonly found on 1960s and 1970s link-detached houses with flat-roofed garages and porches or shops with flat-roofed rear stores below flats. Wales averages roughly 1,460 mm of rain a year, among the wettest in Britain, so we design for steady run-off: proper falls, clear outlets and upstands well above the finished roof.
How much does a flat roof survey cost in Colwyn Bay?
Guide price in Colwyn Bay: £140–£280 for a condition survey and leak investigation, including VAT at Wales rates. 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 regulations in Wales
The Welsh Approved Document L applies. Renovating more than half of a roof over a heated room means upgrading it to around 0.16 W/m²K where feasible, and new extension roofs are built to 0.13 W/m²K. Welsh Government guidance is that most re-roofing needs building control approval, so check whenever more than a quarter of a roof is replaced or repaired. We deal with the application as part of the job. More on the rules.

Does a moisture meter work on every flat roof?
Not equally well. Readings vary with the material, and some coverings, foils and metal layers can affect them, which is why we treat readings as a guide and confirm doubtful areas with a core.

Yes. We survey flat roofs on shops, offices, units, blocks of flats and HMOs, with the report structured so a landlord, managing agent or owner can plan and budget the work.
