Because they are available in a variety of materials and profiles, they may be utilized for nearly any project, from DIY to professional construction.

Choosing Your Corrugated Sheets

Corrugated roof sheets are a very common sight all around the world, including in the United Kingdom. They're quite popular as a roof covering for a wide range of buildings, and they may also be applied to structures made of UPVC cladding.

This document will look at five of our most prevalent materials, including bitumen, metal, polycarbonate, PVC, and fiber cement.

Corrugated bitumen roofing sheets are made of fibers that have been impregnated with bitumen (the same substance used to pave roads). This is why these materials are so robust and lightweight at the same time. They're also suited for a wide range of uses, such as garages, sheds, summerhouses, carports, stables, shelters, and other outbuildings. As a result of the efforts of industry leaders Corrapol Onduline and Caroline, these sheets are now available in a variety of colors.


Another product that utilizes this distinctive style is corrugated metal roofing sheets, which are yet another example. The same advantages apply to all types of corrugated sheeting: increased drainage and impact resistance. Corrugated metal roofing sheets are an excellent example of this enormous strength. These sheets are both lightweight and long-lasting since they are made of aluminum or galvanized steel. The greatest Logs, which are frequently used in commercial and agricultural constructions like warehouses and barns, can last a century or more.


Polycarbonate is a long-lasting and virtually unbreakable material that is also resistant to UV radiation damage. This means the resin in them will not discolor or deteriorate with time. Bitumen, on the other hand, is more resistant to wear and tear. Because they are so flexible, they can be used in a wider range of roof shapes than metal or Perspex. Furthermore, owing to their transparent finish, these sheets allow for excellent light transmission in conservatories.

In many respects, PVC resembles polycarbonate. Both are lightweight, shatterproof alternatives for glass paneling that are considerably safer. PVC corrugated sheets are not only waterproof, but they're also cost-effective and have a high light transmission rate. The most significant disadvantage of PVC is that it has less resistance to impact than polycarbonate. Although polycarbonate is more durable, it may be destroyed by extreme weather. Roofing constructed of PVC will last only ten years or so.

Fibre Cement

Corrugated fiber cement roof tiles have a wide range of advantages over other materials. These panels are composed of reinforced composite material and are therefore extremely durable. Traditional stucco is less resistant to fire than fiber cement siding. These are popular insulation materials for walls, as they're both long-lasting and fireproof, with excellent thermal and sound insulation and ventilation. They're ideal for use in both agricultural and industrial settings because of this.

Installing Corrugated Roofing

Installing corrugated roofing is surprisingly simple, whether you're a novice or an expert. The majority of corrugated sheeting manufacturers also include bespoke fasteners and coverings in their products. Corrugated roofing is usually installed in a similar manner by various manufacturers. Despite the fact that each manufacturer's installation procedures may vary somewhat, they all have several similarities. As usual, seek guidance from the maker's installation instructions to get the most out of your roof and avoid voiding your warranty.

Safety Considerations

Safety must be considered regardless of the size or scale of the task. The Health and Safety Executive has a wealth of information on this issue, as well as reiterating several important factors to consider. It's critical to double-check that any ladders, scaffolding, or other rigging you intend to use meets the following standards: Unless you're replacing a shed, always utilize at least two people and keep hazardous equipment out of reach of children when doingalion.

Fixings and Flashings You’ll Need

  • Screws/Nails: They're clear as day and should be used at a spacing of 200-300mm at the corrugation's peak.
  • Eaves Filler: These are designed to bridge the gap between your eaves and your sheets, which is produced by the corrugated undulating form.
  • Wall Flashing: When your roof sheets abut a wall and will get a finish that prevents water entry.
  • Ridge Cap: This will be a one-of-a-kind product designed specifically for your roof's ridge. This is frequently accompanied with an overhang that may be linked to the tops of your sheets.
  • Verge: This is another component that will be used to finish the sheets where your roof meets the gable, much like the Ridge Cap.

Tips for Fixing Corrugated Roofing

  • When you buy your linen, it's a good idea to get the same manufacturer's flashing and fasteners. This will ensure that all parts of your roofing system are compatible.
  • Cover non-UV-protected papers with a tarpaulin to keep them away from direct sunlight.
  • Be careful about hanging sheets on windy days, since they may be lifted and destroyed. It's especially important to be cautious when using low-density polyethylene (LDPE) sheets (which are more prone to being lifted).
  • PEX, rather than PVC, should not be cut in particularly chilly weather because this may induce significant damage. These sheets should be kept for 2-4 hours in a warm location before being cut.
  • To ensure that you don't miss a location, arrange your sheets on your roof in an unplanned manner before drilling holes in them. This will save time and money by allowing you to identify each hole position with a felt pen.

Corrugated roofing sheets are a strong and flexible material that may be utilized for both agricultural and industrial structures. These sheets are simple to install if you follow the manufacturer's installation instructions, as well as any precautions regarding windy days when putting them on your line. It's critical to think about compatibility when installing corrugated roofing from each manufacturer.
