The rollout method is the safest of the roof erection method as it allows the operators to erect the roof from a safe working platform (being a stepped gable end scaffold).
There is no certified course for temporary roofing. We offer specific product training and first-time site hand-holding to assist with product familiarisation and site applications.
Yes. Temporary roofs are complex structures that can impart large forces into the scaffold and supporting structures. Additional experience and knowledge is required to ensure safety and works should be only be undertaken or supervised by advanced level scaffolders.
Yes, scaffolds with temporary roofs are Encapsulation Constructions as defined by BS EN16508 and beyond the scope of ‘Basic Scaffolds’ as defined in TG20. Temporary roofs are complex structures that can impart large forces into the scaffold and supporting structures, the overall stability and integrity of the structure needs to be assessed and detailed by a qualified and competent Engineer.
Temporary roofs are complex structures that can impart large forces into the scaffold and supporting structures, therefore the overall stability and integrity of the structure needs to be assessed and detailed by a qualified and competent Engineer. As a general rule, a scaffold supporting a temporary roof will require more anchors, bracing and ballast than a physically tied independent scaffold.
We supply designers risk assessments as part of our contract design service and can offer advice and examples of risk assessments and method statements to contractors involved in erection of temporary roofs.
Our temporary roofs can be fitted to any supporting scaffold structure. We provide support components to integrate seamlessly with system scaffolding and a range of lattice girders to provide a continuous roof support in installations where the supporting scaffold and roofing members do not align.
This can be achieved through rolling roofs or pre-planned “access bay” positions. Having a rolling roof over an opening, and moving it to one site is a quick and efficient way to open the roof. Installing horizontal braces to the underside of the top chord on the unbraced bays allows a fixed roof to be easily accessed by removal of sheets and horizontal braces.
Yes. Multiple bays can be erected on the ground and lifted into position. A number of factors need to be considered to achieve this such as crane capacity and reach, the availability of lifting beams or the possibility of installing secondary trusses through the roof beam lines for stability.
Retro-fitting a tubular tie bar to a previously installed roof is difficult. For this reason we always recommend the tie tube system is installed at ground level where the roof can be lifted and lowered to ensure hole alignment and an easy fit of the elements. A tension cable can be installed following roof installation, we recommend our connection plates are pre-installed prior to roof bay installation to provide a solid connection point for the tension cables.
