Why upgrade to a warm roof in Brechin?
Many flat-roofed extensions and dormers in Brechin 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.
Brechin's flat roofs are mostly on 1960s and 1970s link-detached houses with flat-roofed garages and porches, with plenty on terraced streets with flat-roofed rear kitchens and bathrooms too. 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 warm roof upgrade cost in Brechin?
Guide price in Brechin: £2,650–£4,650 for a 20 m² extension roof in EPDM with a new deck and insulation, including VAT at Scotland rates. The fixed price comes after a free survey for new and replacement roofs.

| Extension (20 m²), EPDM with sedum green roof | £4,200–£7,700 |
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
- Upstands, trims and kerbs reset to the new roof level
- Building standards handled where needed
- Survey of the deck, joists and existing insulation
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.

Can you insulate a flat roof from inside instead?
It is possible, but insulating between or under the joists creates a cold roof, which needs ventilation and carries a higher condensation risk. When the roof is being re-covered anyway, a warm roof from above is usually the better option.
Is a warm roof worth it on a garage?
On a detached, unheated garage, usually not, as there is no heated space to protect and the thermal rules don't normally apply. On an integral or heated garage, or one being converted into a room, it is.
