What flat roof work do we do in Haringey?

Warm roof insulation upgrades

Kitchen extensions in Haringey, as elsewhere, produce a lot of moisture from cooking. Under a cold flat roof, that moisture can condense on the deck. A warm roof keeps the deck warm and puts a vapour control layer in the way, which lowers the risk considerably.

Dormer roofs

Buyers' surveys in Haringey often flag dormer roofs, because they are hard to see from the ground and easy to neglect. A recent replacement, with building control sign-off where needed and written guarantees, answers that question before it becomes a problem in the sale.

EPDM rubber roofing

Where an older flat roof in Haringey has a sound structure but a tired covering, EPDM is a straightforward upgrade: strip, check the deck, add a warm-roof build-up if the room below is heated, and bond the new membrane. It also makes a good base for a sedum green roof.
