How to fix corrugated board on the roof

You can improve the weather resistance and durability of your roof in a practical way by fixing corrugated board. Corrugated board provides a lightweight yet durable solution for both new roof installation and roof repair. This kind of roofing material is well-liked for both residential and commercial buildings due to its strength and resilience to different weather conditions.

Make sure you have all the tools and supplies you’ll need before you start. These usually consist of corrugated sheets, hammer or drill, fasteners like nails or screws, and safety equipment like goggles and gloves. For an installation or repair to be successful, preparation is essential. The corrugated board will adhere more firmly and last longer if the roof surface is free of debris and is clean and dry.

To begin, precisely measure and cut the corrugated sheets to fit the dimensions of your roof. To avoid damage and make sure the sheets line up correctly with the roof structure, it’s crucial to handle these sheets with care. To allow for water drainage, place the first sheet at the lowest point of the roof and slightly overlap it with the next sheet. Make sure the sheets are evenly spaced and sufficiently tightened by using the proper fasteners to firmly attach them to the roof.

As you work, take note of the corrugated board’s alignment and general appearance. This improves the roof’s functional qualities in addition to its visual appeal. To guarantee a seamless fit, you might need to make modifications or cuts depending on the slope and style of your roof. Take your time and carefully finish each step, making sure to look for any loose fasteners or gaps that might jeopardize the structural integrity of the roof.

What is corrugated board and what varieties exist

Let’s define corrugated board first and discuss the various subspecies that make up this material. This material consists of ritual steel sheets with a wave-shaped profile, whose protrusions’ height and width are governed by specifications. This form allows the profiled sheet to have a small metal thickness while still having significant rigidity.

In order to prevent corrosion, protective materials such as polymer film or galvanizing are applied externally. The latter imparts a particular color to the material.

Important: There are a few options available for coating corrugated board to provide protection. The most popular is polyester, while polyester with Teflon is less common but offers better defense against harmful effects of the outside world. In addition, steel sheets—which are coated outside of PVC and PVDF—are more costly but offer the highest level of resistance and durability for the material.

Characteristics of different corrugated board coatings

There are three primary varieties of profiled sheet, and each is appropriate for constructing specific building structural components. We will use the table below to familiarize ourselves with this material classification.

Crucial: the figure that follows the profiled brand’s letter designation indicates the material’s height of corrugation in millimeters. When purchasing, consider it carefully.

One of the most crucial factors affecting the roof’s durability and strength is the caliber of the materials that were purchased. As a result, we provide some basic guidelines to assist you in selecting high-quality corrugated board.

  1. Know the manufacturer of the material that you plan to use-study reviews, find out if this corrugated board used any of your friends or neighbors.
  2. Be sure to control the main sizes of profiled sheets – the length, width and height of the corrugation.

Advice for purchasing corrugated board

Crucial! When covering the roof with corrugated board, I should be mindful of the color as much as the brand, size, and quality of the material. It should complement the building’s walls and base without blending in with the surrounding area.

After addressing the issue of what color corrugated board is, you must select a shade that is perfect for a particular type of home.

Rules for cutting corrugated board

It would seem like a straightforward question to ask when installing a corrugated board roof: which tools should be used to cut the material into the necessary sizes? The most popular tool in practically every home, the corner grinding machine, also referred to as the "Bulgarian," is used for this purpose. However, there is a section in the profile steel flooring instructions that either discourages or outright forbids using a grinder to cut material. If not, the corrugated board warranty is deemed to be void. Why is that the case?

The issue is that during the process, the angular grinding machine gets extremely warm. Consequently, the metal at the cut site may melt, taking the external protective layer with it. The damaged zone can span three, five, or even more millimeters in width. Additionally, this seems like a small amount to start the corrosion process on the sheet’s edge and cause gradual damage to the corrugated board. Furthermore, flying sparks have the ability to slightly harm the protective layer, and far from the cut edge, reddish spots may eventually appear in their place after a few years.

An illustration of why cutting a profiled steel sheet with a grinder is not a good idea

As a result, cutting a profiled sheet with a grinder is not recommended (at least not for more than a few years, if we are not installing a temporary roof). If you don’t have any other tools, though, try making thin cuts; this way, the damage can be lessened and the chance of the material being damaged reduced.

Grinding discs: an explanation of the label

Another reasonably priced tool that works well for this is a pair of manual scissors or a metal saw. They are inexpensive, widely available, and when cutting, they don’t damage corrugated board as much as a grinder does. However, they also have certain disadvantages. First of all, using a manual tool to cut a steel profiled sheet is a laborious and time-consuming task. Second, in order to create a straight cut line free of burrs and other flaws when using a saw or hand scissors on metal, you will need to possess a certain level of accuracy and skill.

Using scissors to cut metal

A disk saw fitted with a special blade designed for this purpose and operated at low speeds would be a good choice for cutting a profiled sheet on a roof. Electric with a metal blade is an additional option. However, you should typically only use him to cut corrugated board with low corrugation heights because otherwise, the sheet will break and sustain significant mechanical damage.


Crucial! Use safety measures and wear safety glasses when handling tools like disk saws and grinders.

When it comes to cutting quality and productivity, using an electric scissors and a special, pricey guillotine for metal is a great choice. However, they are a specialized tool that you probably won’t use very often.

Counseling! Offering the seller to divide them beforehand using a metal guillotine is a reasonable option if you did extensive calculations before beginning the roof and are certain of the sizes required. This will reduce the risk of corrugated board becoming contaminated by improper cutting technology, save time and strength, and possibly simplify the process of delivering the material to the house.

Step 1: Prepare the Roof Surface Clear debris and ensure the roof is clean and dry.
Step 2: Measure and Cut Measure corrugated boards to fit the roof dimensions. Use tin snips to cut them if needed.
Step 3: Start at the Bottom Begin at the bottom edge of the roof. Place the first sheet with the corrugations running vertically.
Step 4: Overlap and Secure Overlap adjacent sheets by at least one corrugation. Use screws with neoprene washers to secure each sheet to the roof structure.
Step 5: Seal and Finish Apply sealant to the overlapping corrugations to prevent leaks. Ensure all sheets are securely fastened and trim any excess material.

A sensible and affordable method to improve your home’s resilience and appearance is to install corrugated board on your roof. You can guarantee a safe and weather-resistant installation that will shield your property for many years to come by following a few simple steps.

To start, planning is essential. Make sure your roof is clear of debris and clean before beginning. Look for any damage on the surface and fix anything that needs fixing. A strong, stable foundation is necessary for working on.

Next, collect your supplies and equipment. Corrugated boards, the right fasteners (like roofing screws or nails), a drill bit set, safety gear (like goggles and gloves), and corrugated boards are required. The procedure will go more smoothly if you have everything ready before starting.

Working your way upward, start the installation from the lowest point on the roof. In order to guarantee adequate drainage and stop leaks, corrugated board sheets should be overlapped. To firmly fasten the boards to the roof structure, use the appropriate fasteners and place them in the crests of the corrugations.

Double-check the sheets for any gaps or loose fasteners after they are in place. Check for stability and uniformity throughout the installation and tighten as necessary. Installing corrugated board correctly will improve the appearance of your roof and offer dependable weather protection.

Finally, keep your corrugated roof maintained by routinely inspecting it for wear, debris accumulation, and loose fasteners. As soon as possible, take care of any problems to prolong the life of your roof and guarantee that your house will remain safe.
