When is a repair the right answer in Brecon?
Small businesses in Brecon 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.
Brecon's flat roofs are mostly on low-rise post-war blocks of flats, with plenty on terraced streets with flat-roofed rear kitchens and bathrooms 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 Brecon?
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.
| Job | Guide price inc VAT |
|---|---|
| Localised patch repair | £140–£460 |
| Upstand or flashing repair | £230–£600 |
| Outlet or drainage repair | £110–£320 |
| Emergency temporary weatherproofing visit | £170–£410 |
| Condition survey and leak investigation | £140–£280 |
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.

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.

Flat roof repairs in Brecon: questions

How much does a flat roof repair cost in Brecon?
£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 a GRP roof be repaired?
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.
Will a repair affect my roof's guarantee?
It can. If the roof is still under a manufacturer's material guarantee, the repair should normally use that manufacturer's products and methods, so share any guarantee paperwork with us before work starts.
