From aesthetics and style to durability and strength, the “wave” like profile in roofing sheets corrugated offers a number of different benefits for your roof structure.
Firstly, the larger surface area and corrugated design allow the sheets to disperse weight from heavy force more evenly across the surface, improving the stability and durability of the roof.
Thanks to this additional strength, corrugated roofing is also often very thin which makes it significantly lighter than other sheets.
What’s more, the corrugated waves also allow water to shed from the roof surface very easily. Minimising the risk of leakages and water damage. In terms of visual appeal, many find the corrugated look adds a stylish, And classic appeal to a roof structure, especially on farm buildings.
How Much Should Roofing Sheets Corrugated Overlap?
The “wave” like profile of corrugated roofing sheets allow them to overlap easily with each other when installed. It is important to overlap corrugated sheets. Because this will help prevent water ingress into the building below and enhance structural stability.
Although the general rule is to allow at least one corrugation for overlapping. This will depend on the pitch of your roof which will be supplied in your manufacturer’s guide. For 10° pitches, an overlap of 150mm is generally recommended whilst 300mm is typically advised for 5° pitches.
The overlapping should be done in the direction of the wind. For example, if the wind blows from the east, overlap the left sheets on to the right. Doing this will stop wind from blowing the sheets apart during fitting.
