When is a repair the right answer in Carryduff?
Small businesses in Carryduff 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.
Carryduff's flat roofs are mostly on newer estates where the first extension roofs are now being replaced, with plenty on lock-up garage blocks on estates too. Northern Ireland averages roughly 1,150 mm of rain a year, spread over many wet days, so a roof that sheds water quickly to clear outlets lasts far longer than one that holds puddles.
How much does a flat roof repair cost in Carryduff?

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 control in Northern Ireland
In Northern Ireland, Technical Booklet F1 sets roof insulation at 0.18 W/m²K when a roof over a heated room is renovated or newly built, where that's feasible. The district council's building control should be contacted before work starts, and we prepare the details it asks for. More on the rules.
