Board Layout & Falls Design

The design of falls and board layout of a successful tapered roof design must take several factors into account:


  • Position of rainwater outlets.


  • The amount of water run-off required.


  • Roof dimensions.


  • Existing falls or steps on the roof.


  • The location and measurements of permanent projections such as roof lights, vents etc., along with any perimeter restrictions.


Project specific designs detailing the board layout and directions of fall can be drafted quickly and efficiently for approval. These initial designs will account for the required U-Value, alterations or amendments can be easily integrated.


Once the final design has been approved by the client working drawings will be produced. These drawings will clearly set out the fall pitch, fall direction and correspond with the board count provided and delivered to site on time.
