Warm roof insulation upgrades in Erskine

Converting a cold flat roof to a warm roof is a sensible upgrade for many flat roofs in Erskine. The old covering is stripped, the deck is checked, and a vapour control layer, rigid insulation and new waterproofing go on top, with trims and upstands raised to suit.

Why upgrade to a warm roof in Erskine?

Many flat-roofed extensions and dormers in Erskine were built with little or no insulation, or with a cold roof that was never properly ventilated. Those rooms are often hard to heat in winter and can suffer condensation, mould and, in time, a rotten deck.

Around Erskine, flat roofs are common on lock-up garage blocks on estates and on bungalows with flat-roofed side extensions and dormers. 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?

  • Building standards handled where needed
  • Vapour control layer on the warm side of the insulation
  • Survey of the deck, joists and existing insulation
  • New waterproofing, with a written workmanship guarantee

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.

It greatly reduces the risk by keeping the deck warm and placing a vapour control layer on the warm side. Good ventilation in kitchens and bathrooms below still helps.
