Flat roof surveys and leak tracing in Frome

Not sure whether the damp patch in your Frome 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 Frome?

Buyers in Frome sometimes find a general survey flags a flat roof as a concern without saying much more. A specific flat roof survey fills that gap, describing the condition and likely cost of any work so it can be factored into the decision.

Around Frome, flat roofs are common on 1930s semis with flat-roofed garages and kitchen extensions and on bungalows with flat-roofed side extensions and dormers. The South West averages roughly 1,260 mm of rain a year and many roofs face wind off the Atlantic, so we specify fixings and edge details for wind uplift as well as drainage.

How much does a flat roof survey cost in Frome?

Guide price in Frome: £150–£310 for a condition survey and leak investigation, including VAT at South West 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.

What's included?

  • Inspection of the covering, upstands, edges and outlets
  • Core samples where readings need confirming
  • Moisture meter readings across the roof
  • Checks on walls, copings and trays above the roof

Building regulations in England

Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.

How much does a flat roof survey cost in Frome?

£150–£310 for a condition survey and leak investigation, at South West guide rates including VAT. We confirm the price once we've traced the leak or seen the damage.

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.

Can a survey tell how old my flat roof is?

Only approximately. The type of covering and its condition give a reasonable estimate, but paperwork such as an invoice or guarantee is the only reliable record.
