I Need A Temporary Roof Cover – What Are My Options?

A temporary roof is used to provide a weather-resistant covering for a building project. A variety of sheeting options are available for cladding a temporary roofing roof, including zinc roofing sheets (often referred as ‘CI sheets’), temporary roofing systems’ like Haki, Ubix, etc., and shrink wrap sheeting.

Controlled environments can be used to mean many things. Sometimes, it’s as simple as keeping the work area clean. Sometimes, there are more precise requirements regarding temperature and humidity control.

Corrugated Iron

This traditional material is used to cover temporary roofing sheets made of corrugated steel. Sometimes called tin sheets or CI sheets. It is still used to cover a construction project with a “tin hat”.

Once the scaffolding is up, corrugated iron sheets are laid on the roof in an over-tiled configuration. They are then secured to the roof beams below.

Tin sheets can be reused on multiple jobs if they are used carefully. However, each sheet must be lifted into place individually. This can increase labour costs and require scaffolders to fit the roof. Here’s an example of a temporary roof made from CI sheets.


  • Re-usable


  • Do not allow light to penetrate the work area below.
  • Safety and health considerations.
  • Sheeting requires large upfront investments.

Saveya Roof

Saveya describes a temporary roofing technique that is used by large companies. Aluminium beams measuring 1.5m or 3.0m in length can be joined together to create a maximum 15m span. The aluminium beams come with tracks, which allow a sail to be pulled up the mast of a sailing boat. However, the exact design will vary depending on the manufacturer. Double and single tie bars, as well as diagonals with snap-on “claws”, can stiffen the trusses. This product has a bay width of 2.57m. After the beams have been installed, the sheeting with sealing beads is (Saveya), pulled through the tracks.

This is a comprehensive explanation of the Keder sheeting systems.

Saveya is an excellent option for temporary roof edge protection. Although it can provide a comfortable working environment, the limited flexibility means that shrink wrap may be better suited for some situations. There are both advantages and disadvantages to saveya.


  • Sheets that can be reused
  • Lightens the work environment


  • It can be very expensive
  • Shrink wrap is not as versatile

Plan a temporary shrink wrap roof

Shrink wrapping doesn’t require the initial scaffolding design considerations for a temporary roof system like Haki or Ubix. However, covering a scaffolding roof using shrink wrap sheeting requires some planning.

To batten the shrink wrap, additional scaffold boards must be secured to the roof surface. A hand rail around the perimeter will also be required to protect the edges and provide anchorage points for safety lines.

You will also need to plan to make the most of the best weather window. Shrink wrap sheets in wet or windy conditions can significantly impact the product’s strength and performance.

Your team might need to learn how to shrink wrap in order for you or your client to get the results they desire.

Rapid Fitting

Corrugated Tin Sheet (CI), is usually fitted to scaffolding structures in sections of 2m x 1m (2m2) (after any overlaps have been considered), while shrink wrap sheets are generally fitted in sections of 7m x 15, (105m2) which seem to offer shrink wrap sheeting a clear advantage in terms fit speed.

It is not enough to simply roll the shrink wrap sheet over a temporary roof. The shrink wrap sheet will need to been battened at regular intervals (we recommend every two metres), and overlaps with other shrink wrap sections will need sealing by heat welding. Finally, the entire shrink wrap wrap cover will need heat shrinking by heating it using a propane gas hot-air gun.

Weather Resistance

Rain: Shrink wrap sheeting has far fewer joints than Tin Sheet Roofs. Any joints that do exist are heatwelded. Rain can’t penetrate more efficiently if there are fewer gaps.

Wind: Shrink wrap is often used to cover the sides of scaffolding. Temporary roofs are more difficult to install. A high wind blowing on a shrink wrap roof can create a low pressure area under the shrink wrap, which causes a significant upward force or suction. We recommend that scaffolders securely clip scaffold boards. The shrink wrap can then be battened at intervals approximately 2 meters to prevent damage. These boards are usually three-boards wide and allow for access to the shrink wrap sheeting once the sheet has been unrolled.

Installers Tip: When installing a shrink wrap sheet on a temporary roof, we attach a self-adhesive strip of foam between the battens and the shrink wrap. This foam acts like a gasket and prevents water from entering through the shrink wrap’s screw holes.


Shrink wrap roofs will look smarter, more professional and have less work area than a tin sheet roof. The entire area can be enclosed and kept contained by extending the shrink wrap sheeting along the scaffolding sides. Shrink wrap sheeting can be used as a temporary roof covering. It is easy to adapt to any size or shape of the scaffolding structure.

Removing a Temporary Roof

When comparing shrink wrap sheeting to tin sheets for temporary roof coverings, one thing to keep in mind is how long it takes to remove the roof cover after the project is complete. You can easily cut the shrink wrap film into sections and bundle it for collection at your site or at your yard. This is much faster than removing the tin sheets and stacking them for transportation back to your yard.

Temporary roof covers are not the right product for every application or situation.

The ‘system’ roof is the best temporary roof option. It has been tested and proven to be effective on the most prominent construction projects in the UK.

Shrink wrap sheeting works best for temporary roofs that are small and awkward.
