Design a roof as a system of connected details

A roof plan introduces the need to coordinate surfaces, equipment and drainage; this is not a waterproofing specification.

The design question
A roof includes more than its visible top surface. Water outlets, upstands, equipment bases and access points all form part of its performance. A material described as waterproof cannot compensate for poorly resolved junctions or blocked drainage.

What to consider
Have the relevant designers coordinate levels, falls, waterproofing, insulation where appropriate and maintenance access. Check how plant installation or a later cable route might damage the assembly. Keep drainage routes understandable and inspectable rather than concealed wherever convenient.

Your next step
Request the agreed testing procedure, product records and maintenance guidance at handover. Discuss who checks outlets and how repairs can be carried out safely. Roof planning should account for the way the building will be operated after construction, including changes that future occupants may want to make.
