Flat roofs with continuously supported flexible waterproof coverings. Code of practice
| Published By | Publication Date | Number of Pages |
| BSI | 2018 | 34 |
This revised edition of BS 6229 describes best current practice in the design, construction, care and maintenance of roofs with a flat or curved surface, at a pitch not greater than 10 degrees to the horizontal, with a continuously supported flexible waterproof covering. The supporting structure is either dense and heavy (such as a concrete slab), or consists of framing members supporting a lightweight deck of metal or of timber-based material.
NOTE Provided that the design conditions are similar, many of the recommendations contained in this code of practice apply to roofs at pitches greater than 10 degrees and to those designed as a Green Roof supporting planting.
This British Standard does not apply to certain types of cold stores and high temperature enclosures.
