When is a repair the right answer in Dumbarton?
Older flat roofs in Dumbarton, 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 Dumbarton, flat roofs are typically found on shops with flat-roofed rear stores below flats, and on lock-up garage blocks on estates. 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.
How much does a flat roof repair cost in Dumbarton?
For Dumbarton we use Scotland rates: £140–£480 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?
- Upstands, flashings, laps and seams made good
- Fixed price confirmed in writing before work starts
- Leak path traced from the stain back to the entry point
- Inspection of the whole roof, not just the wet patch
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.
