What does a balcony or terrace in Brymbo need?

A roof terrace in Brymbo may be re-waterproofed when the owners want to change the finish, swapping old tiles for decking or porcelain on pedestals. Lifting the surface exposes the membrane, and replacing it then avoids having to lift the new finish again later.

In a town like Brymbo, flat roofs are commonly found on 1960s and 1970s link-detached houses with flat-roofed garages and porches or shops with flat-roofed rear stores below flats. Wales averages roughly 1,460 mm of rain a year, among the wettest in Britain, so we design for steady run-off: proper falls, clear outlets and upstands well above the finished roof.

Do I need planning permission for a balcony or roof terrace?

For a new balcony or roof terrace, generally yes. In England, balconies and raised platforms are not permitted development for houses, so a planning application is normally needed, and the other nations have their own rules.

Re-waterproofing an existing, approved balcony that looks the same afterwards does not normally need planning. Building regulations are a separate question. A terrace over a heated room is a thermal element, so replacing most of it can bring insulation requirements and approval. Turning a flat roof into a terrace also raises structural questions, because people, furniture and paving add load, and it needs guarding, such as a balustrade, that meets the regulations. A structural engineer should confirm that the roof can carry the new use.

Listed buildings and conservation areas add another layer of control. Our building regulations page covers approvals, and our planning permission guide covers the planning side.

What's included?

  • Sealed details at doors, outlets, walls and balustrade posts
  • Free survey of the deck, falls, outlets and door thresholds
  • Lifting and setting aside of existing paving or decking
  • Strip-out of the failed membrane and deck repairs

Building regulations in Wales

The Welsh Approved Document L applies. Renovating more than half of a roof over a heated room means upgrading it to around 0.16 W/m²K where feasible, and new extension roofs are built to 0.13 W/m²K. Welsh Government guidance is that most re-roofing needs building control approval, so check whenever more than a quarter of a roof is replaced or repaired. We deal with the application as part of the job. More on the rules.

Do you install balustrades?

Our work is the waterproofing and drainage. We detail the membrane around balustrade fixings so they stay watertight, and we can advise on where posts should be fixed.

What is an inverted roof terrace?

It is a terrace where the insulation sits above the waterproofing, held down by paving or ballast. The membrane stays protected and at a steadier temperature.
