Part L1B of the Building Regulations - a short guide for flat roofing.
A lot customers have never heard of Part L of the Building Regulations and I find myself explaining these regulations all the time, so I have uploaded this video and hope that it helps anybody looking to find out more. Part L and flat roofing are becoming more and more tied together. We always try to form a warm roof for our flat roofs, we find that a warm roof construction for flat roofing is by far the best flat roof. There is a lot less to go wrong with a warm deck flat roof than with a cold deck flat roof. Building Control and Part L only dictate the U value of a roof, however if you form a cold deck flat roof then you also have to ventilate the roof.
Warm deck flat roofs and cold deck flat roofs can be covered with EPDM rubber, mineral felt, asphalt, Kemper and lead, zinc and copper.
