Good practice guidance is provided by:
-
BS 8217:2005 for design, installation and maintenance of reinforced bitumen membranes for roofing.
-
BS 6229:2003 is the code of practice for flat roofs with continuously supported coverings. It recommends these are inspected at least twice a year in spring and autumn and also after events that may have had a detrimental effect on the roof covering, such as violent storms.
-
Workmanship is covered by BS 8000-4:1989 - but this standard is a bit dated and covers a limited range of issues.
