Green and sedum roofs in Brechin

A green roof in Brechin looks best when it starts from a properly built flat roof. That is why we treat the waterproofing as the main job and the sedum as the finish, using a warm or inverted build-up to suit your roof and a root barrier where the membrane needs one.

Why choose a green roof in Brechin?

Garden rooms and outbuildings in Brechin, as elsewhere, often have small flat roofs that are seen from the house and garden. A sedum finish helps them blend in, provided the structure is strong enough and the roof underneath is built properly.

In a town like Brechin, flat roofs are commonly found on low-rise post-war blocks of flats or terraced streets with flat-roofed rear kitchens and bathrooms. 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 long does a green roof last and how much maintenance does it need?

A well-built extensive green roof needs one or two maintenance visits a year, and the plant layer can help protect the membrane from sunlight and temperature swings.

Typical maintenance means pulling out weeds and tree seedlings before they root, clearing outlets and the gravel strips around edges, filling in any bare patches, and adding a slow-release feed if the sedum looks thin. Sedum is drought-tolerant once established, but newly laid blankets may need watering in a long dry spell during the first season.

The waterproofing underneath has the same expected life as on any other roof of that system. A green roof also slows down rainwater run-off from the roof and, when sedum flowers, attracts bees and other insects. Some councils encourage green roofs for those reasons, so it is worth mentioning one in a planning application for a new extension. Our maintenance guide covers routine checks.

What's included?

  • Structural check of joists, deck and supports

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.

How much does a green roof cost in Brechin?

Does a green roof leak more than a normal flat roof?

No, as long as it is built correctly. The waterproofing beneath is what keeps water out, and the green layers protect it from sun and weather. The main risk is building it on a weak or ageing membrane.

Can you put a green roof on a pitched roof?

We install green roofs on flat roofs only. Sloping green roofs need extra restraint to stop the growing medium slipping, and they are a specialist job outside our work.
