Flat roof repairs in Abertillery

We carry out flat roof repairs in Abertillery on garages, extensions, dormers, porches and small commercial roofs. Each visit starts with a look at the whole roof, so the repair deals with the point where water actually gets in rather than the patch that shows on the ceiling, and you get a written price before any work begins.

When is a repair the right answer in Abertillery?

Small businesses in Abertillery with a flat-roofed shop, office or unit can't leave a leak running over stock or equipment. A repair stops the water at its entry point, and our inspection tells you whether the rest of the roof needs attention soon or can safely be left for now.

Abertillery's flat roofs are mostly on 1930s semis with flat-roofed garages and kitchen extensions, with plenty on lock-up garage blocks on estates too. 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 Abertillery?

For Abertillery we use Wales rates: £140–£460 is the guide for a localised patch repair, VAT included. 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?

  • Leak path traced from the stain back to the entry point
  • Repairs with materials compatible with your roof system
  • Upstands, flashings, laps and seams made good
  • Fixed price confirmed in writing before work starts

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.

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

Can you repair the roof if the ceiling is already damaged?

Yes. The roof is fixed first so the ceiling can dry out, and then a plasterer or decorator can make it good. Any wet insulation within the roof should be checked, as it may need replacing.

Why does my flat roof only leak in heavy rain?

Usually because water only reaches a weak point when it builds up: a partly blocked outlet, a low spot where water ponds, or an upstand that is too low for the depth of water. Wind-driven rain against a wall above the roof is another common cause.
