Roof Design

Refer to BS 4841: Part 3 and Single Ply Roofing Association guidance when designing flat roof systems.

Falls

Flat roofs must incorporate adequate fall to prevent water pooling and ensure proper drainage.

Fire Performance

Fire classification for 100mm Unilin FR-MG, when assessed to EN 13501-5 and BS 476 Part 3 'External Fire Exposure Roof Test', depends on the waterproofing system selected.

Vapour Control Layer

A continuous, approved vapour control layer must be installed beneath the insulation (except over sealed metal deck systems). For mechanically fixed boards, use minimum 1000 gauge polythene sheeting, lapped and sealed with double-sided tape below the Roof insulation. At vertical upstands and penetrations, turn up the VCL and seal to fully encapsulate the insulation before completing the roof finish.
