What flat roof work do we do in Dumbarton?
Extension and kitchen roofs
Condensation drives some replacements in Dumbarton. Older extension roofs were often built cold, with insulation between the joists and no reliable vapour control. Warm air from the kitchen reaches the cold deck, moisture builds up and the timber suffers. A warm roof deals with the cause, not just the stain.
Balconies and roof terraces
A roof terrace in Dumbarton may be re-waterproofed when the owners want to change the finish, swapping old tiles for decking or porcelain on pedestals. Lifting the surface exposes the membrane, and replacing it then avoids having to lift the new finish again later.
Flat roof surveys and leak tracing
Landlords and managing agents in Dumbarton often need a written record of a roof's condition, for budgeting, for leaseholders, or to show a problem has been looked at properly. A survey report gives them a clear basis for deciding when to repair and when to replace.

Local weather shapes the specification. 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. Approximate 1991–2020 regional averages based on Met Office data.
Who approves flat roof work in Dumbarton?
