Flat roof surveys and leak tracing in Sunderland

Not sure whether the damp patch in your Sunderland 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 Sunderland?

Flat roofs in Sunderland 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.

Sunderland's flat roofs are mostly on newer estates where the first extension roofs are now being replaced, with plenty on lock-up garage blocks on estates too. England averages roughly 870 mm of rain a year; the North East is drier than the west but cold and windy near the coast, so wind uplift and freeze-thaw are in the specification.

How much does a flat roof survey cost in Sunderland?

For Sunderland we use North East rates: £140–£280 is the guide for a condition survey and leak investigation, VAT included. We confirm the price once we've traced the leak or seen the damage.

What does a flat roof survey report cover?

The report sets out what the roof is, what condition it is in and what we recommend, in plain language.

  • The roof system, approximate area and how the roof is built, as far as can be seen.
  • The condition of the covering: splits, blisters, crazing, lost chippings, open laps and wear.
  • Upstands, flashings, edge trims and rooflights.
  • Falls, ponding and the state of outlets and gutters.
  • Moisture readings and the findings of any core samples.
  • The likely cause of any leak, and how confident we are in it.
  • Recommended action, ranked by urgency, with guide costs.

We are clear about what we could and couldn't see. A survey can't inspect hidden timbers without opening them up, and we will say where a finding is an inference rather than a direct observation.

What's included?

  • Inspection of the covering, upstands, edges and outlets
  • Core samples where readings need confirming
  • Plain written report with ranked recommendations
  • 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 Sunderland?

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

Do I need a roof survey when buying a house with a flat roof?

It's worth considering if the general survey flags damp, ponding or an ageing covering, or if the roof is large. A specific flat roof report gives you a clearer idea of what work may be needed and what it might cost.

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.
