What flat roof work do we do in Swindon?

Flats, HMOs and block roofs

When a roof over heated flats in Swindon is replaced, insulation rules usually apply. We design the warm-roof build-up towards the required standard where that is feasible and handle building control where it is needed, so the work is signed off properly and the top-floor flats are better insulated.

Warm roof insulation upgrades

Small commercial buildings in Swindon with large flat roofs can lose a lot of heat through them. Where the roof is being replaced, upgrading the insulation at the same time is required in most cases and helps reduce running costs for the occupier.

Flat roof surveys and leak tracing

Buyers in Swindon 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.

What flat roofs are typical in and around Swindon?

In a city like Swindon flat roofs are mostly on newer estates where the first extension roofs are now being replaced and 1930s semis with flat-roofed garages and kitchen extensions. Local weather shapes the specification. 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. Approximate 1991–2020 regional averages based on Met Office data.

Where approval is needed it goes to Swindon Borough Council building control, or a registered building control approver. 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. How the rules work.
