Extension and kitchen roofs in Montrose

Replacing an extension roof in Montrose usually takes a few working days and rarely puts the kitchen out of action. We plan the strip so the room is weathertight each night, rebuild the roof with insulation to current guidance, and handle the approval paperwork across Angus where it applies.

What makes a good extension roof in Montrose?

Condensation drives some replacements in Montrose. 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.

In and around Montrose, flat roofs are typically found on newer estates where the first extension roofs are now being replaced, 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.

Which flat roof system suits a kitchen extension?

On a plain rectangular extension, EPDM rubber is a strong, quiet choice that can often be laid in one sheet. It handles the slight movement between an extension and the house well.

Where the roof has a lantern, several rooflights or an internal corner, GRP fibreglass forms neat, rigid details around each one. Torch-on felt is a proven layered system and keeps costs down, though near timber cladding or at fragile junctions we may prefer a cold-applied method. If the extension is overlooked from upstairs windows, a sedum green roof is worth considering, provided the structure can take the extra load.

Whatever the membrane, the insulation sits above the deck as a warm roof. Our warm vs cold roof guide explains why.

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 a sedum roof go on my extension?

Possibly, if the structure can carry the extra weight and the roof has suitable falls and drainage. We check the joists at survey before recommending it.

Can you keep my existing roof lantern?

Often, if the lantern itself is sound. We lift it, rebuild the kerb, dress the new membrane up the upstand and refit the lantern.
