When is a repair the right answer in Rhondda?

In a place like Rhondda, flat roofs usually sit over garages, rear extensions, dormers and bays, and they take the full force of the weather with little margin for error. A single failed lap or a cracked upstand is enough to let water into a kitchen, bedroom or hallway below.

In a large town like Rhondda, flat roofs are commonly found on 1930s semis with flat-roofed garages and kitchen extensions or low-rise post-war blocks of 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.

How much does a flat roof repair cost in Rhondda?

At Wales guide rates, a localised patch repair comes to £140–£460 including VAT. We confirm the price once we've traced the leak or seen the damage.

Which repair materials work with my type of flat roof?

The repair has to use the same system as the roof, because many flat roof materials don't bond to each other and some damage each other.

  • Torch-on felt: repaired with compatible bitumen membrane, cut back to sound felt and lapped well beyond the defect. Torching near timber, insulation or fascias needs care, and some details are better done with cold-applied methods.
  • EPDM rubber: repaired with EPDM patches and the manufacturer's primer and seam tape. Bitumen products and many general-purpose sealants won't bond to EPDM and shouldn't be used on it.
  • GRP fibreglass: the area is ground back, then new resin and glass matting are laid and finished with topcoat to match.
  • Liquid-applied and single-ply: repaired with the same manufacturer's products wherever possible, as mixing systems can affect a material guarantee.
  • Mastic asphalt: cracks and blisters are cut out and made good with new asphalt by an operative who works with it.

A tin of roof sealant or bitumen paint may stop a drip for a while, but on the wrong membrane it makes a proper repair harder later.

What's included?

  • Repairs with materials compatible with your roof system
  • Upstands, flashings, laps and seams made good
  • Inspection of the whole roof, not just the wet patch
  • Outlets and gutters cleared while we're on the roof

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.

Yes. The damaged area is ground back, new resin and matting are laid over it and a matching topcoat goes on top. Cracks that keep reappearing along the same line often point to movement in the deck, which needs fixing first.
