The Hardy Farm project was installed for Bethel of Britain.
Their multi level flat roofed building was in a poor state with constant leak problems. The client contacted Advanced Cladding & Insulation of Manchester for a permanent solution.
ROframe was the ideal structure for creating a “flat to pitch” conversion over the complex roof shape due to its simplicity of use, total accuracy of component lengths using the site cropping tool and economy through minimum waste of materials.
Advanced Cladding & Insulation used their established installer Des Allen and his team to carry out the work resulting in a simple dual pitched roof draining to external gutters and downspouts.
Here is the original building with extended perimeter overhangs supported on plywood beams. The felt roofs had sloping side areas draining to a central flat roof with internal drainage. Also there were several redundant extractor fans which also had leak problems.
After removing the extended perimeter overhangs the existing roof joist locations and proposed new roof tilt frame positions were marked out and the base members fixed in place. Then construction of the tilt frames began with bracing members fitted as the work progressed.
Both the tilt frames and purlins were installed on a simple grid of 1500 mm with the base members being laid perpendicular to the existing roof joist directions in order to evenly distribute the new roof load.
Here we see the Roframe section cleats fixed over the tilt frames at spacings of 1500 mm centres. Then the same ROframe section is fitted over the cleats in Zed format to create the robust purlin.
The new eaves detail comprised of a structure overhang of 300 mm plus an outboard box gutter in order to replicate the original overhang. All elements of the structure overhang are formed from the ROframe section.
