What flat roof work do we do in Rhondda?

Torch-on felt roofing

Where a flat roof in Rhondda already has a felt covering and the building owner wants like-for-like, torch-on is the natural replacement. The old roof is stripped, the deck checked and the new layers laid, often with warm-roof insulation added when the space below is heated.

Warm roof insulation upgrades

Converting a garage, loft space or outbuilding to a room in Rhondda changes what the roof needs to do. Once the space is heated, the roof is expected to perform to a higher standard, and a warm build-up is usually the simplest way to get there.

Green and sedum roofs

Homeowners in Rhondda building a new extension may find a green roof can help with a planning application, as some councils encourage them for biodiversity and slower rainwater run-off. It is worth raising early with your designer, before the roof structure is drawn up, so the joists can be sized for the extra weight.
