What flat roof work do we do in Norris Green?

Green and sedum roofs

Small commercial buildings and blocks in Norris Green with a flat roof sometimes add an extensive green roof as part of a refurbishment. The structural check and safe access for maintenance matter even more on these larger roofs, which may need edge protection or fall-arrest points for each visit.

Extension and kitchen roofs

Condensation drives some replacements in Norris Green. 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.

Liquid-applied roofing

Liquid systems suit balconies and walkways in Norris Green because they form neatly at door thresholds, railings and drains, and some products are designed to take foot traffic. Converting a roof into a new terrace is a different matter, and usually needs planning permission first.

The climate is part of the brief. The North West is one of England's wetter regions, averaging roughly 1,290 mm of rain a year, so falls, outlets and well-detailed upstands matter more than the membrane colour.
