Warm roof insulation upgrades in Hawick

A flat roof in Hawick that drips in cold weather without any rain is often suffering from condensation rather than a leak. Upgrading to a warm roof when the covering is replaced deals with the cause by keeping the deck above dew point and adding a vapour control layer.

Why upgrade to a warm roof in Hawick?

Kitchen extensions in Hawick, as elsewhere, produce a lot of moisture from cooking. Under a cold flat roof, that moisture can condense on the deck. A warm roof keeps the deck warm and puts a vapour control layer in the way, which lowers the risk considerably.

Around Hawick, flat roofs are common on newer estates where the first extension roofs are now being replaced 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.

Can a cold flat roof be converted to a warm roof?

Yes, and it is the usual approach when an older cold roof is re-covered. The old covering is stripped, the deck is checked and replaced where needed, and the vapour control layer, insulation and new waterproofing go on top.

The existing insulation between the joists is assessed at the same time. Leaving it in place can create a cold, unventilated gap that traps moisture, so it is often removed or the build-up is designed so that most of the insulation sits above the deck. We decide this case by case once we can see inside the roof. If the covering is still sound and you are only patching it, the upgrade isn't usually required, and our repair or replace guide explains how to decide between the two.

What's included?

  • Vapour control layer on the warm side of the insulation
  • Building standards handled where needed
  • Rigid insulation boards sized to the U-value target
  • Upstands, trims and kerbs reset to the new roof level

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.
