What flat roof work do we do in Grangemouth?
Flats, HMOs and block roofs
Fire performance matters near boundaries and on occupied buildings in Grangemouth. We check the external fire classification of the whole roof build-up, not just the membrane, control or avoid hot works near escape routes and windows, and keep fire-stopping details intact where the roof crosses a separating wall.
Extension and kitchen roofs
Condensation drives some replacements in Grangemouth. 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.
Flat roof replacement
A flat roof in Grangemouth is often worth replacing because it is the weak point of the building: heat escapes through an uninsulated deck, rooms below are cold in winter and hot in summer, and condensation marks the ceiling. A warm-roof replacement deals with comfort as well as leaks, so it is worth considering before the roof fails outright.
