Temporary Roof

A short roof is a modular covering system that you can use to protect your building or site area for a short period. They can effectively shield your new construction project or a site under maintenance against different weather conditions.

You can set up the temporary roofs easily and quickly with their high adaptive feature. If you want to reinstall them for some other construction site, you can also dismantle them quickly and reinstall them elsewhere.

Figure 1 – A Typical Temporary Roofing Example

You need temporary roofs for:

• Protecting your unfinished structure: There may be cases when you need to hold your construction works for some financial matters or unforeseen complexities for a substantial amount of time. But obviously, your structure will be critically damaged during this time due to harsh weather conditions.
  You may be looking for permanent roofing plans at that time, but eventually, you will have to break that off. So, you will waste excess money. The better option for you, in this case, should be to invest a lesser amount of money after temporary roofing systems. You can dismantle them when you are done.
• Create a temporary working station: During the construction, your staff may require a temporary station near a facility where they need to work. So, you can create a small and temporary roofing system for their comfortable working environment.
• Repair works: If you perform repair works in a damaged area, you need to build a temporary roof to proceed with a cost-effective solution.
• Equipment and material storage: Storing construction materials or equipment under an open sky will damage them. You can create a shed with a temporary roof for their protection and storage.
• Save time: When the construction work is underway, you don’t want to waste your valuable time installing a permanent roof. Since you can install temporary roofs in a short period, your time will be saved securing a temporary roofing system.
• Crane access: If you need to enable crane access for material transferring through a structure, you need to use mobile roofs that you can open during material transfer.
• Emergency requirements: Temporary roofing materials are made with fire-retardant materials. So, you can use them reliably in areas where you have the regulations to maintain fire-retardant standards.

There are different types of temporary roofs that you can use for construction sites. The common ones are:

• Corrugated iron or tin sheeting:You can use different sheeting options to cover over the roof scaffoldings like tin sheets to create a temporary cover.
  But the initial investment for this kind of temporary roofing is high since you need a high investment for the sheeting materials. Another issue is that the roof completely blocks off incoming light, so the inside environment is dark.

• Keder roof: The keder is a highly practical temporary roofing solution. It is actually not a single roof but a roofing system consisting of a railing system and sheeting. This roofing system is extremely popular since you don’t need any additional tools to install the complete roof.
  You can secure the connections using the built-in boltless connection features. You can quickly and easily connect the rails with the sheeting fabric.
  Most of the time, the railing components are manufactured from aluminium, which makes them extremely lightweight and durable. For the sheeting material, you can choose from a range of different types of fabric roofing sheets.

• Ubix roof: You can install the ubix roofing system on any scaffolding system or tube fittings. Due to the component’s design features, you can assemble very long spans from 20 m up to 35 m or more. So, they are a very practical temporary roofing system in large-scale construction sites.
• Cassette roofs:  Cassette roofs are extremely strong and built with steel cassettes. You can quickly install this roofing system with a few additional components. You can also create extensively long spans with this roofing system.
• Shrink-wrap temporary roof:  You need to assemble scaffolding components on the topmost surface to clamp the shrink-wrap in a shrink wrap roofing system.

The temporary roofs are constructed to protect your structure or site from harsh weather conditions. So, the manufacturers design them so that they can efficiently sustain against weathering agents like:

• Rain: The top sheeting that you install with the frame provides the ultimate protection against rain. They are manufactured from waterproof materials. So, they pass the accumulated water through the designed drainage to the ground.
• Sunlight: Any covering you use for the temporary roofs will withstand the high UV ray from the sunlight. Most manufacturers induce anti-UV absorbing agents in the sheeting material in a process called ‘anti-UV stabilisation’. It makes the materials durable against UV rays.
• Wind: The frame of the temporary roof system, whether you use a scaffolding system or railing frame, can withstand high wind speeds. But you have to plan and design them first to withstand the wind pressure and force.

Most of the time, in construction sites, you need roofing solutions temporarily. If you invest in a permanent roofing solution, you have to break them again when you are finished with your project.

So, you need additional costs to break them after use. Additionally, the initial cost of material is also higher for permanent roofs.

On the other hand, if you use temporary roofing systems, you need a smaller initial investment. Even you can quickly and easily dismantle them after usage and use them for other areas. So, the temporary roofing solution is better for your construction sites.Figure 4 – Shrink Wrap For Temporary Roofing

When buying the sheeting material for your temporary roof, you must ask the supplier to prove the fire-retardant properties.

Manufacturers integrate additives with the materials so that they can extinguish themselves after a short period after you remove the source of the fire. The temporary roof sheeting materials comply with flame retardant European standard EN13501-1, class B S1, D0; and some manufacturers offer materials that comply with flame retardant EN 13501-1: 2013 Class B – s2, d0 with M1 standards.
