How much does a flat roof survey cost in East Sussex?

Guide prices including VAT at South East rates. We confirm the price once we've traced the leak or seen the damage.

Which flat roofs are common in East Sussex?

Flat roofs in East Sussex sit on low-rise post-war blocks of flats, shops with flat-roofed rear stores below flats and terraced streets with flat-roofed rear kitchens and bathrooms. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain. Approximate 1991–2020 regional averages based on Met Office data.

Building regulations in England

Replacing more than half of a roof over a heated room usually counts as renovating a thermal element, so it is insulated to current standards and notified to building control. Renovated roofs over heated rooms are insulated to around 0.16 W/m²K where that's feasible, and new extension roofs are built to 0.15 W/m²K. In East Sussex the application goes to Brighton & Hove City Council, Eastbourne Borough Council, Hastings Borough Council and 3 other councils. More on the rules.

Will the survey tell me whether to repair or replace?

Yes. That is one of the main things a survey is for. Isolated damage on a dry, sound roof points to repair. Wet insulation, a soft deck, widespread cracking or repeated leaks point to replacement.

The report puts that recommendation in context, including the roof's age, its system, how long a repair would be likely to hold and whether the thermal upgrade rules would apply to a replacement. If you decide to replace, it also helps you choose between stripping the roof back and overlaying it. Our repair or replace guide and overlay or strip guide go into more detail.

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.
