What is corrugated roofing?
Corrugated roofing is a highly popular and widely used sheet roofing format that utilises large material sheets. They are typically made from metal, polycarbonate, polyester, PVC or cement and have a corrugated pattern, meaning the material is shaped into a series of parallel ridges and grooves.
The properties of corrugated sheeting give it several highly useful practical characteristics which make it ideal for a wide variety of industrial, commercial and domestic roofing applications.
What are the benefits of corrugated roofing?
The versatility and value of corrugated roofing have made it immensely popular over decades of use. Although different corrugated materials are better used in some areas of roofing than others, corrugated roof sheets in general share a number of key benefits.
Strength and impact resistance: The wavy build of each corrugated sheet offers incredible flexural properties. This means corrugated sheets offer greater resistance than equivalent flat sheets to loads that would typically bend the sheet across the corrugations – for example, snow or heavy winds. The corrugated shaping also allows for greater impact resistance, dissipating any impact forces across a larger surface area.
Consistent water run off: Corrugated roofing is best built on an angle. This allows water to run off away from the structure and eliminate any risk of pooling, roof leaks and the associated damage from them.
Durability: While longevity differs between materials, the durability of all corrugated roof sheets is outstanding, with virtually all types of corrugated sheet expected to last at least 10 years, rising to decades with metal options.
Rot and weather resistance: Unlike other roofing materials, metal corrugated roofing in particular is not susceptible to rot. This factor, combined with its strength properties, makes corrugated roofing highly capable of dealing with all weather conditions, from torrential rain and hailstorms through to snow and frost.
Lightweight: Despite its toughness, corrugated roofing is incredibly lightweight, making it easy to handle, move and manipulate, as well as offering no unnecessary load bearing on the property.
Easy to install: That lightweight factor, coupled with the large area of corrugated sheets compared to standard roof tiles, makes them very simple and quick to install, even for inexperienced DIYers. This means you can either eliminate labour costs on a project by installing them yourself or lower them significantly thanks to the reduced effort required to fit them.
Types of corrugated roofing
Corrugated metal: Made from chemically coated, galvanised steel for unchallenged strength and durability, corrugated metal roofing benefits larger agricultural and commercial structures, and is found across countless industrial applications.
Corrugated bitumen: Made with hard-wearing bitumen fibres that create high tensile strength, bitumen corrugated roofing offers an all-weather solution for garden and agricultural settings. Versatile in size and appearance, the Burton Roofing range includes four different colours of bitumen sheet: black, red, brown and green.
Corrugated plastic: Our corrugated plastic roofing sheets and corrugated Perspex roofing sheets use a variety of polycarbonate, PVC and polyester finishes to offer a durable but lightweight and transparent roofing solution.
