Temporary Roofs
What are the traditional options for temporary roofs?
Traditional solutions for encapsulating a temporary roof scaffolding include the fixing of tin / CI sheeting or perhaps installing of a ‘system’ roofing product where strips of reinforced sheeting are pulled through tracks in the roof beams.
Types of temporary roof;
Full Roof
A full roof is used where total weather protection or environmental containment is required.
Canopy
A canopy is often used to provide weather protection to construction activities on the facade of the building, such as rendering.
Some benefits of shrink wrapping for temporary roofs
Versatile - shrink wrap is particularly suitable for smaller or awkwardly shaped roofs.
Lightweight - approximately 0.30Kg/m2.
Excellent light transmission rate - allows almost all available natural light through to the work area.
Smart & professional – The drum tight finish of Rhino scaffold shrink wrap sheeting, which is shrunk tight around the scaffold structure can look much more professional than traditional solutions, (especially if the scaffolding structure has been built with scaffold wrapping in mind).
Buyers Guide – Shrink Wrap for Temporary Roofs
Because of the wind loadings that can be experienced by temporary roof sheeting, it is particularly important to ensure that you;
- Choose a scaffold wrap film that has been engineered specifically for use on scaffolding. You need a shrink wrap film that welds / joins strongly (and stays welded) and that shrinks powerfully so that the roof sheeting is tensioned ‘drum tight’. For an in depth buyers guide to shrink wrap sheeting click here.
- The scaffolding structure over the roof needs to be set out correctly. For details on setting out scaffolding for shrink wrap sheeting download our free guide
- To achieve the best performance from a shrink wrapped temporary roof it is important that the installation takes place in light winds and dry conditions. This will allow joints to be welded and the sheeting to be heat shrunk tight.

Temporary Roofs – Frequently Asked Questions
How do I set up the scaffolding structure for a temporary roof?
For smaller temporary roofs and canopies less than 6 metres wide where there is complete and safe access to all of the underside of the roof then it is possible to shrink wrap the roof area by working from underneath. In this case, the scaffold structure should be flush. Sheeting rails mounted on to the surface and edges of the roof can provide additional support improve the finished appearance and reduce the possibility of holes being created by scaffold tube ends or fittings.
For temporary roofs over 6 metres wide or where the entire sheeted area cannot be accessed from underneath, the sheeting must be installed from above. The roof should be fully boarded with a hand rail around the perimeter to provide edge protection. The roof should have a pitch of at least 10% to shed rainwater.
What size shrink wrap film is best for temporary roofs?
Our scaffold shrink wrap films are available in rolls that open out into widths of 12 metres but we most often recommend (& use ourselves) our ‘signature’ 7m wide x 15m long roll. The 7 x 15m roll has a shrink ratio of 60% in the machine direction and 45% in the transverse direction which creates the tightest fitting temporary roof covering.
What guarantee do you provide for temporary roofs installed by the Rhino Shrink Wrap installation team?
Our normal guarantee applies for any shrink wrap installation work that is carried out by our own teams, either on scaffold facades on roofs. Our standard warranty for shrink wrap that we install is 25 weeks subject to wind speeds up to and including 47mph. However, it is not possible to guarantee a 100% watertight envelope. Due to the complexity of temporary roof structures, there is always the possibility of small drips and ingress where scaffolding tubes pass through the shrink wrap sheeting (such as where beams overhang the edge of the roof).
