Advantages and Disadvantages of Corrugated Metal Roofing

Corrugated metal roofing

Corrugated metal roofing is one of the most common types of metal roofing

This type of roofing involves using panels to create a wavy or rippled pattern. 

With this roofing material, the metal sheets are stiffened so homeowners can get greater coverage over a lighter framework.

If you’re considering a metal roof for your home, you have probably explored not only corrugated metal roofing but also standing seam metal roofs and metal shingles. 

Making a final decision between these options requires you to consider the pros and cons of each option available to you.

Corrugated metal roofing is a popular choice for many good reasons. 

It’s not just about its sturdy nature or energy-saving qualities; there’s much more to it. 

We unpack the significant benefits this material offers that may be the perfect solution for your construction or renovation needs.

▪️ Eliminates Water Build-Up

A corrugated metal roof is built on a slope, allowing water to run downwards, away from your home.

This measure aids in mitigating the potential for water damage to your home, a crucial consideration for individuals residing in regions prone to heavy rainfall.

▪️ Quiet

Homeowners may be concerned about getting metal roofing because the material will amplify the sound of rain and other weather conditions like snowfall and hail. 

However, they don’t need to worry – corrugated metal roofing, in particular, has no sound difference in comparison to clay roofs.

▪️ Long-Lasting

Corrugated roofing uses steel or aluminum as the main metal material.

With proper maintenance, this implies that it can endure for as long as a century, ensuring you are free from any concerns about rusting.

▪️ Weather-Resistant

Corrugated metal roofing holds up very well against all types of weather conditions. Weather, such as rainstorms, snow, hailstorms, and frost, among others, can be challenging.

However, the advantage of a rust-free roof is that you can rest easy knowing you won’t have to replace it unexpectedly during inclement weather.

▪️ Tough and Lightweight

Corrugated panels are not only flexible and durable, they are also very lightweight.

That’s precisely why it has gained immense popularity among homeowners.

Their lightweight nature also means that they are easy to install and do not put too much weight on your building.

Heavier roofing materials require you to make costly modifications to your building’s structure to ensure no damage due to the weight.


Corrugated metal roof disadvantages

While corrugated metal roofing is widely appreciated for its numerous benefits, it’s important to consider the potential drawbacks as well.

Issues such as installation cost, noise during rain, and certain aesthetic limitations might influence your decision.

As we explore these aspects further, you will gain a balanced perspective to make an informed choice.

▪️ Not Suitable For Flat Roofs

Corrugated metal roofing should not be installed on homes that have a flat or low-sloped roof.

This occurs when there is insufficient inclination on your roof, causing water to accumulate instead of effectively draining off as intended.

The longer that water stays on your roof, the more likely you will get leaks.

If your home has a low roof slope and you reside in a rainy area, corrugated roofs may not be the optimal selection.

▪️ More Maintenance

While all metal roofs require at least annual maintenance, corrugated metal roofing requires more frequent checks.

With this type of metal roofing, it is important to inspect the fasteners to ensure their condition regularly.

Fasteners on corrugated panels are exposed.

As a result, they have a tendency to become less secure, creating gaps that allow water to seep in, causing leaks and subsequent water damage.

Corrugated roofing will need to be inspected after any severe weather events.

Additionally, it is important to inspect your roof for any signs of cracked sealant and assess the condition of the foam closures.

Ensuring the structural integrity of these components will help maintain the overall quality and performance of your roof.

▪️ Noise

Corrugated metal roofs can be noisy during heavy rain or hail storms.

However, you can mitigate it to some extent with the use of sound-deadening insulation and solid plywood sheathing.

▪️ Denting

It is important to note that metal roofing, significantly thinner gauge ones, can be susceptible to denting if walked on. 

Heavy hailstorms can also cause dents on metal roofs. 

Therefore, it is advisable to exercise caution and take necessary precautions to prevent any potential damage to the roofing material.

▪️ Cost

Metal roofing is a premium home product, so it’s more expensive than most other roofing materials.

You’ll need to consider whether the higher upfront cost will be worth the long-term benefits.

▪️ Expansion and Contraction

Metal roofing materials are attached as large panels expand and contract. Incorrect installation of fasteners that allow the metal to “breathe” may cause the panels to loosen.

▪️ Inconsistent Color Match

If you need a repair or a home extension years later, you may find it difficult to locate an exact match to the existing metal. 

This is because of variations in metal finishes and aging effects, making it challenging to source the precise material needed.

Considering factors like color, texture, and overall appearance becomes crucial in ensuring a seamless integration of the recent addition with the existing structure.

Final Thoughts

Commerical building using corrugated metal roofing panels.

Corrugated metal roofing has both its pros and cons.

They are budget-friendly, and it is easy to find roofers who know how to work with them.

However, they tend to require more time commitment from you long-term and may not be suitable for your roof type.
