Any kind of metal roof offers a high degree of protection against roof fires. Corrugated galvanized steel roofing, in particular, is one of the best solutions from this point of view as its completely non-combustible and is the safest roofing option in regards to lightning strikes.
The vast majority of corrugated metal roofs are made from at least 80% of recycled metal. They also are extremely durable and can be recycled again when they near the end of their lifespan. Therefore, this roofing solution is one of the greenest options available.
Are There Any Cons to Corrugated Steel Roofing?
Before the galvanization technology became popular, this roofing system had a major disadvantage because it wasn’t rust-resistant. However, this problem has been effectively solved by the creation of galvanized corrugated roofing panels. They are the most popular corrugated metal option used in Toronto today due to their affordability and durability.
Note that galvanized corrugated steel is a material that will change its appearance over time. In a couple of years, it will become duller and develop a white oxide look. This is not a reason for worry as this is zinc’s (material used for galvanization) natural defense mechanism against oxidation and weather damage. The attractiveness of the original look may be restored by applying specialized coatings.
Corrugated steel roof sheets available today are rather light and easy to install. This, combined with the low prices, makes them an excellent choice for commercial properties. The only drawback that this system has is its vulnerability to dents. A piece of debris thrown on the roof during a storm or a fallen tree branch can leave a sizeable dent in the surface.
In the majority of cases, the dent itself is not a problem as long as there are no piercings in the surface. However, this affects the aesthetical appeal of the roof and reduces its lifespan. Small dents can be effectively fixed by our experienced roofers. If the damaged area is too large, the best solution is replacing the panel.
If you are looking for an affordable, reliable, and weather-resistant roofing system, corrugated steel panels are one of the best choices available. They offer a higher degree of protection and energy efficiency than corrugated plastic roofing and will increase the value of your property.

Modern corrugated metal roofing systems deliver resistance to corrosion, are energy efficient and are a very economical roofing solution for commercial, industrial, agricultural, and in some cases even residential use. Thin gauge steel (usually 24 or 26) comprises corrugated roofing panels, which is very practical and economical in covering large roofing surfaces. Moreover, corrugated metal roofing costs much less than standing seam and is much more practical and lasting than asphalt shingle roofs.
There is a number of materials from which corrugated roofing can be made, such as; aluminum, galvalume coated steel, galvanized steel or stainless steel. Galvalume steel corrugated roofing provides the most lasting and economical roofing solution, as it is not only incredibly durable and reliable, but is also very cost effective. Moreover, if covered with a special Kynar coating, a corrugated metal roof can also provide significant savings on your energy bill.
Over the years, much technological advancement has been made, allowing for great improvements in the aesthetic appeal as well as the integrity and quality of corrugated roofing. Corrugated roofing has become a viable alternative to conventional asphalt shingles, which can end up in a landfill following as little as 15 years of service. Metal roofing is more expensive than shingles; however corrugated roofing systems are quite affordable in contrast with standing seam metal roofing.
Individual roofing sheets used for this type of systems are incredibly strong due to the corrugations, which are created using a process of roll-forming. It ensures a much greater bending strength of corrugated metal roofing panels, compared to that of flat paneling. Bending strength of the material is increased only in the direction of the corrugations and does not apply across them.
There is a variety of different possible corrugation types to serve a number of different purposes. Curved corrugations are typically applied to metal sheets, giving the roof a wavy appearance. The sheets are installed in an overlapping manner by accurately fitting the corrugated edges of each sheet over the other. Another commonly used pattern of corrugations is a square shape, which can be particularly useful in the installation of roof decking, because this shape provides great support. The optimal type of corrugation for your specific property is defined by the location, purpose and size of the building. Ultimately, corrugated metal roofing is a fitting choice for many building types, as it offers exceptional durability and very low maintenance costs.
Installing Corrugated Metal Roofing
- Panels are applied with the corrugations running in a straight line between the highest and lowest points of the roof and at a right angle to the purlins (intermediate supports).
- Side overlaps of sheeting are installed in a manner which directs them away from prevailing winds.
- Then, hook bolts (8 mm in diameter), coach screws, or crank bolts are inserted through the holes (10 mm diameter) that are drilled in the crowns of the corrugations.
- These nuts or screws are first slightly tightened, and when a dozen or more roofing sheets have been laid, they have tightened again.
