When is a repair the right answer in Grangemouth?
Older flat roofs in Grangemouth, as elsewhere, are often covered in felt that has lost its chippings and dried out. One leak on a roof like that is a warning sign. We repair it, check the rest of the covering and tell you honestly whether replacement belongs in next year's budget.
In and around Grangemouth, flat roofs are typically found on 1960s and 1970s link-detached houses with flat-roofed garages and porches, and on low-rise post-war blocks of flats. Scotland averages roughly 1,570 mm of rain a year, with the west far wetter than the east, so drainage, falls and wind uplift are part of every specification we write.

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 standards in Scotland
In Scotland the building standards technical handbooks (Section 6 for energy) apply, and the council's building standards service decides whether a building warrant is needed. Like-for-like repairs to a roof covering can be exempt; alterations, structural work and new roofs usually need a warrant before work starts. The domestic roof benchmark is 0.12 W/m²K, applied as far as reasonably practicable on an existing roof. More on the rules.

How much does a flat roof repair cost in Grangemouth?
£140–£480 for a localised patch repair, at Scotland 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.
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.
