At Sika, our technical teams within the roofing department monitor updates to industry regulations and British Standards to help ensure our technical support and specifications reflect current requirements. As a manufacturer, we engage with recognised guidance documents and standards that promote regulatory compliance and responsible practice across the roofing and wider construction industry.
We provide reference to relevant standards and guidance documents covering flat roof construction, thermal design, fire classification, condensation control, energy efficiency, specification development, installation, and maintenance.
If you require further detail regarding any of the listed standards, please contact our roofing technical team. Contact information is available on our product information webpage
Industry Regulations
BS:6229:2018 – Flat Roofs with Continuously Supported Flexible Waterproof Coverings
Superseding BS 6229:2003, this current version reflects modern best practices in flat roof design, including drainage, thermal performance, condensation control, and fire precautions. It excludes fully supported metal roof coverings, which are now covered under BS Technical Committee B/542.
BS:13501 Series – Fire Classification of Construction Products
This European classification system replaces the BS 476 series in Approved Document B. It includes Broof(t4) testing for roof coverings and is now the sole route for fire classification in England. BS EN 13501-5 is specifically relevant for roof exposure to external fire.
BS:476
Specifies methods of test for construction materials in relation to fire.
BS:5250:2021 – Control of Condensation in Buildings
This code of practice provides guidance on managing moisture and condensation risks in buildings. It complements BS 6229 by covering condensation risk analysis in more detail.
Approved Document L(England) / Section 6 (Scotland) – Conservation of Fuel and Power
Provides guidance on compliance with energy efficiency requirements for buildings. It applies to both dwellings and non-dwellings and is regularly updated to reflect changes in building regulations.
BS:12056 – Gravity Drainage Systems Inside Buildings
This standard covers design principles for gravity drainage systems, including rainwater runoff and gutter design.
