Lightweight roofing solutions are extremely popular with homeowners and tradespeople alike.

Easy to handle and install, they’re also incredibly sturdy and durable, making them a highly versatile solution suitable for a wide range of applications and every weather.

At Roofing Superstore, we’re exciting offer a comprehensive range of bituminous roofing tiles and accessories, along with an innovative new metal tile system, from Ariel Plastics, one of the UK’s best choices for roofing products.

These roofing sheets, which are marketed under the Corotile, Coroline and Onduline brands, are suitable for small to medium building projects, from DIY home and garden applications to small commercial and agricultural buildings.

However, each product comes with its unique qualities.

So what’s the difference between Coroline and Onduline corrugated sheets?

Let’s find out more about Corotile, Coroline and Onduline!

The main difference between Coroline and Onduline corrugated sheets

Shed with Coroline Onduline roof sheets

The biggest difference between Coroline and Onduline corrugated sheets is weight, followed by thickness and price point.


Both products are heavier duty than lower quality counterparts available on the market. However, Onduline is slightly heavier (3.3kg/m2 compared to 2.9kg/m2).

What’s more:

It is also thicker (3mm compared to 2.6mm). When considering projects on taller buildings, builds where the roof sheets will be exposed or where there is a higher wind loading, Onduline is the more substantial product in these conditions.

Our lowest price black Onduline sheet is around £2.20 more than its Coroline equivalent.

Onduline is also BBA-approved, whereas Coroline is not. Although not an issue for the type of applications normally associated with these roof sheets, it may occasionally be a factor in your choice.

Where Coroline and Onduline are the same

Other than the points mentioned above, there is very little difference between these superior roof sheets.

Onduline roofing sheets

The good news is:

Onduline and Coroline sheets are both tough roofing and cladding materials. They are manufactured from bitumen-saturated organic fibres. These fibres have been exposed to intense pressure and heat, helping to provide long-lasting durability. A 15-year waterproofing guarantee is available on both products.

Both ranges offer excellent colour retention properties. This is thanks to a colour pigment and resin impregnation process that ‘stains’ the colour into the sheet, which is used to finish the products. Enhanced UV resistance is another benefit as a result of this process.

And that’s not all:

Both sheets are available in four colours – black, brown, green and red. The translucent PVC sheet provides an economical way of gaining light transmission through your roof. The hard-wearing material is free from asbestos and is non-toxic.

This delivers an environmentally friendly and attractive solution for domestic roofing projects and commercial and agricultural buildings. A range of matching accessories including polythene eaves fillers, verge and ridge pieces and fixings are available.

What is Corotile?

As if Coroline and Onduline weren’t enough, there’s even a third option – Corotile!

Let’s see what makes it stand out:

Corotile, a new lightweight metal tile roof system, is the perfect solution for a wide range of outdoor applications from chalets, playhouses and sheds, to garages,  garden offices and workshops.

Corotile is quick and easy to install on any sized roof without the need for cutting as the tile sheets simply overlap and screw together, requiring nothing more than a power screwdriver and shear to install a strong, attractive and lightweight roof.

The Corotile roofing system is a complete roofing structure incorporating tile sheets, ridges, fixings, barge boards and end caps. It is manufactured from low carbon Z150 Aluzinc coated steel. This offers an exceptionally robust barrier and superior corrosion resistance.

Corotile is a highly economical, dry fix system with no wastage. Its popular tile profile and charcoal grey colouring offer an attractive and professional finish to any application. Its also virtually maintenance-free thanks to the tiles’ weather sides being primed, acrylic coated and overglazed.

Final thoughts

Both Coroline and Onduline are ideal for external roofing applications, including stables and sheds.

You get to choose from a selection of colour options, as well as stylish miniature profiles, making them an excellent choice for bespoke garden roofing.

Likewise, Corotile is designed for easy installation to help create a robust yet lightweight roof.

With not one or two but three excellent options boasting multiple advantages, the hardest part is having to choose just the one!
