Flat roof surveys and leak tracing in Chepstow

Not sure whether the damp patch in your Chepstow home is a roof leak or condensation? A flat roof survey looks at both possibilities, checking the covering, the details around it and the way the roof is built, before telling you what we think is going on and how to fix it.

When is a flat roof survey worth it in Chepstow?

In Chepstow, as elsewhere, people often book a survey after a repair that didn't hold. When a leak returns, it usually means the first fix treated the symptom rather than the cause. Tracing the actual entry point saves paying for the same repair twice.

In and around Chepstow, flat roofs are typically found on 1960s and 1970s link-detached houses with flat-roofed garages and porches, and on 1930s semis with flat-roofed garages and kitchen extensions. 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 Chepstow?

At Wales guide rates, a condition survey and leak investigation comes to £140–£280 including VAT. We confirm the price once we've traced the leak or seen the damage.

How long does a flat roof survey take and how long is it valid?

A survey of a typical garage or extension roof usually takes an hour or two on site. Larger, higher or multi-area roofs take longer, and the written report follows afterwards.

A survey describes the roof on the day it was inspected. It stays a useful baseline for planning, but roofs change, particularly older ones and after a hard winter or a storm. If you are using a report to plan a replacement some time later, or after a fresh leak, a short follow-up check is sensible. For roofs you manage over the long term, a regular inspection backed by the maintenance checklist picks up problems early.

What's included?

  • Inspection of the covering, upstands, edges and outlets
  • Checks on walls, copings and trays above the roof
  • Moisture meter readings across the roof
  • Plain written report with ranked recommendations

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.

How much does a flat roof survey cost in Chepstow?

£140–£280 for a condition survey and leak investigation, at Wales guide rates including VAT. We confirm the price once we've traced the leak or seen the damage.

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.

Is a core sample damaging to the roof?

It's a small, deliberate opening that is sealed again with compatible material before we leave. It shouldn't affect how the roof performs.
