Roof upgrade – flat to pitch

This section considers the option of a permanent refurbishment solution for failed flat roofs, by using a lightweight steel sub-frame over the existing roof (which is then over-clad), creating an effective pitch to facilitate water run-off.

Before upgrade

Framing systems - Propped rafter system

This system takes advantage of the inherent strength and loading capabilities of the existing structure. This system utilises bespoke rafter sections installed at centres between 1200 mm and 3000 mm, dependant on existing roof construction. Vertical post sections fixed to the existing flat roof structure support these rafters. The lightweight structural framework can be assembled on site.

Trussed rafter system
This system is designed for use on existing roofs that do not
have the capability to support any further load. Instead, factory
assembled clear spanning trusses constructed using a series of
purpose made sections are supported by the existing load bearing walls or columns. Once in place, the trusses are fixed into the connection plates, braced, and the roof purlins secured. Depending on the size of roof the spanning trusses will be delivered as a full unit or in two halves.
