What Is Corrugated Metal Roofing?

Corrugated metal roofing is a type of roofing material made from sheets of metal that are bent into a series of waves or ridges. This gives the roofing a distinctive look and also helps to deflect wind and rain.

This type of roofing is often used on industrial and commercial buildings, but it can also be used on homes.

Corrugated metal roofing is available in various materials, including aluminum, galvanized steel, and copper. It is also available in multiple colors, so you can find one that will match your home’s exterior.

How is Corrugated Metal Roof Manufactured?

There are three different steps to manufacturing corrugated metal roofing.

Step 1: Forming a Sheet in a Mold

The flat steel sheets are heated and placed into a mold to form the right shape. All of the teeth, channels, and other design elements are being formed in this step.

Step 2: Rolling the sheet metal

Once the sheet has been formed in the mold, it’s then sent through a rolling mill. This creates all of the corrugations in the metal.

Step 3: Cutting to length

The metal is then cut to the correct length and width. This is where the panels are aligned to the desired size.

Where to Use Corrugated Metal Roofing?

Corrugated metal roofs are used for a variety of purposes, such as:

  • Homes and businesses where durability and strength is necessary
  • Areas that experience heavy snowfall
  • Areas with high winds
  • Additions, garages, and outbuildings
  • Farm buildings
  • Storage sheds
  • Garages
  • Stables
  • Outbuildings
  • Shops
  • Agricultural buildings
  • Any structure that needs a metal roof that is not asphalt or tile

If you’re not sure if corrugated metal roofing is the right option for you, contact a roofing contractor in your area for a consultation. They will be able to assess your needs and provide you with a quote for the installation.

What Is the Lifespan of Corrugated Metal Roofing?

The lifespan of corrugated metal roofing varies depending on the type of metal, the quality of the installation, and the climate where you live. In general, though, corrugated metal roofing can last 30 to 45 years with proper care.

Types of Corrugated Roofing 

There are a few different types of corrugated roofing to choose from. Here are the most popular ones:

  • Aluminum: Aluminum is a lightweight and corrosion-resistant metal. It comes in various colors and can be painted to match your home’s exterior.
  • Galvanized Steel: Galvanized steel is a durable metal resistant to rust and corrosion. It’s available in a variety of colors and styles.
  • Copper: Copper is expensive, but it provides excellent color consistency with very little maintenance.
  • Bitumen: Bitumen is a relatively affordable option for homeowners on a budget. It’s very durable and can be used in extreme weather conditions.
  • Iron: Iron is heavy, but it has the highest strength-to-weight ratio of all metals. It can be painted, but rust will eventually start to appear.

In addition to the type of metal used for your corrugated roofing, you’ll need to decide if you want standing seam or flat panels. Flat panels are lighter and easier to install, but standing seams give your home a unique appearance.

Which Type of Corrugated Metal Roofing Is the Best?

There is no one-size-fits-all answer to this question. The best type of corrugated metal roofing depends on your budget, the style of your home, and the climate where you live.

In general, aluminum is a smart choice due to its lightweight nature and low cost. Copper is a versatile option that will give your home a distinct appearance, but it’s expensive. Galvanized steel is a popular choice because it’s affordable and can resist rust and corrosion.

As a homeowner, your budget and personal preferences will likely be the biggest factors in your choice. When you’re weighing all your metal roofing options, always make sure to consider the pros and cons of each type.

What Is the Cost of a Corrugated Metal Roof?

A corrugated metal roof will cost anywhere between $10,500 and $19,500 to install. What you spend will depend on the metal roof type, pitch, slope, and size of your roof. Typically, it costs $3.5 to $6.50 per square foot or $350 to $650 per square installed. 

Cost Breakdown

  • Residential high-end 26-gauge and 24-gauge grade metal panels with paint cost $1.50 to $2.50 per square foot. The cost will vary depending on the specific metal type, thickness, roof profile, and whether the paint is custom or standard.
  • Non-residential low-end 26-gauge and 29-gauge steel panels with lower-end paint finish range from $1.00 to $1.50 per square foot.
  • Installation costs range from 4.50 to $5.50 per square foot installed.
  • Residential mid-ranged ribbed or corrugated steel metal paneling with factory-finished –paint costs $5.50 to 8.50 per square foot when fully installed.

Pros and Cons of Corrugated Metal Roofing 

If you’re considering a corrugated metal roof for your home, be sure to weigh the pros and cons carefully. This type of roofing can provide many benefits, but it’s not the right fit for every home.

Benefits of Corrugated Metal Roofing

  • Energy Efficiency – Corrugated metal has a high thermal resistance, meaning it’s a good insulator. If you want to reduce your monthly heating and cooling costs, this is an excellent option for you. Corrugated metal holds up well in both hot and cold climates.
  • Relatively Difficult to Burn – Corrugated metal roofing is a bit more difficult to ignite than other materials, making it a good choice for homes in wildfire-prone areas.
  • Durability – Corrugated metal roofing is incredibly durable and can last for decades with proper care.
  • Low Maintenance – Once your corrugated metal roof is installed, you don’t have to worry about it again. It doesn’t require any painting, and it needs minimal cleaning.
  • Appearance – Corrugated metal gives your home a unique look thanks to its wavy design. Unlike traditional roofing materials, corrugated metal isn’t flat. A new corrugated metal roof will make your home stand out from the crowd of other homes on the block.

Drawbacks of Corrugated Metal Roofing

  • Corrugated metal roofing is more expensive than asphalt shingles.
  • It’s not as aesthetically pleasing as other roofing materials such as slate, clay tiles, or wood shakes.
  • Installation can take longer because the panels need to be nailed or screwed into place.
  • If installed poorly, it can leak and lead to water damage inside the home.

Overall, corrugated metal roofing is a cost-effective, durable, and sustainable option for your home. It’s best suited for homes in areas that experience high winds and hail damage, and it’s a good choice for homeowners looking for low-maintenance roofing material.

Corrugated Metal Roofing vs. Standing Seam Metal Roofing

A corrugated roof is made using metal sheets with alternating wavy and curved ribs. On the other hand, standing-seam roofs are made with panels that consist of formed metal sheets with vertical ribs at panel edges. Standing seam installation is done by lapping and interlocking the edges of adjacent panels.

Both provide excellent protection and durability and give your home an upscale appearance. However, each type of coverage has its own set of pros and cons that may make one more appropriate for your home than the other.

Pros of Corrugated Metal Roofing

  • Inexpensive
  • Many colors and styles are available
  • Durable and resistant to weathering and fading
  • Lightweight, making it easy to install

Cons of Corrugated Metal Roofing

  • Not as aesthetically pleasing as standing seam roofs

Pros of Standing Seam Metal Roofing

  • Aesthetically pleasing
  • More appropriate for cold climates
  • Can be customized to match the style of your home
  • Very durable and long-lasting

Cons of Standing Seam Metal Roofing

  • Heavier than corrugated metal roofs, making it more challenging to install
  • More expensive than corrugated metal roofs

Corrugated Metal Roof vs. Other Types of Roofs

Here is a quick comparison of corrugated metal roofs to some other popular types of roofs:

  • Corrugated metal roofing is cheaper than asphalt shingles but more expensive than metal roofing
  • Corrugated metal roofing lasts longer than asphalt shingles but not as long as metal roofing
  • Corrugated metal roofing is recyclable, while asphalt shingles are not

  • Corrugated metal roofing is available in various colors. In contrast, metal roofing is available in many different types of metals, and asphalt shingles are available in many colors, but not all colors are fade-resistant.

As you can see, there are many pros and cons to consider when deciding whether or not to install a corrugated metal roof on your home. If you’re still unsure, talk to a professional roofer, and they will be able to help you make the best decision for your home and your needs.

What to Look for When Choosing Corrugated Metal Roofing?

When you’re ready to purchase your metal roofing panels, there are a few things that you should keep in mind. These include:

1. The Gauge of the Metal

The thicker the metal, the more durability and better protection your roof will have. However, thicker also means you’ll need to purchase more materials and spend more on installation.

2. The Thickness of the Sheet

Thicker metal sheets are generally stronger than thinner sheets. However, for most residential applications, 24-gauge corrugated roofing is appropriate.

3.  Finish

The finish is another essential factor to consider when choosing your metal roofing panels. Metal roofs are available with either a galvanized or painted finish, while powder coating is also an option. Here are some of the pros and cons of each finish type:

Galvanized Finish -Pros

  • More expensive than other finishes

4. Location

If you live in an area that has frequent strong storms or high winds, be sure to choose a metal panel with an impact resistance rating of at least 350 pounds per square foot (PSF).

5. The Roof Pitch

You can choose a corrugated metal roof that works best for the pitch of your roof.

6. Roofing Accessories

Be sure to order any other accessories and hardware that you need, such as drip edge and ridge vents.

7. The Layout

If you plan on doing the installation yourself, be sure to order extra roofing panels to account for mistakes.

When you’re ready to purchase your metal roofing panels, be sure to ask the supplier about their warranty.

Can You Install Corrugated Metal Roofing Yourself?

It is possible to install corrugated metal roofing yourself, but it is a difficult job and not recommended for novice DIYers. If you’re not comfortable doing the installation yourself, it’s best to hire a professional roofing contractor.

Before you install a corrugated metal roof on your home, it’s vital that you properly prepare for installation by clearing away any debris or vegetation from the roof and cleaning the surface.

Here’s a step-by-step guide on how to install corrugated metal roofing:

  2. Measure your roof to ensure you order the correct amount of metal roofing panels.
  3. Trim the panels to fit the dimensions of your roof using a circular saw.
  4. Apply a layer of adhesive to the surface of the roof and fasten the panels in place with nails or screws.
  5. Seal all seams and edges with a sealant to prevent water infiltration.
  6. Finish the installation by installing ridge and eave caps.
  7. Inspect the roof for any missed spots or areas that need additional attention, and then seal them with a sealant.

Is it better to hire a Corrugated Roofing Contractor? 

Although it’s possible to install corrugated metal roofing yourself, you may not have sufficient knowledge or experience for this type of project.

  • If the installation process seems too difficult for you to handle alone, it’s best to hire a professional roofing contractor near you to do the job instead.
  • If you’re unsure about how long corrugated metal roofing will last, a professional contractor can give you an estimate on how long the roof should last with proper maintenance. They can also help you choose the right type of roofing for your home and offer advice on the best way to install it.

How to Care for a Corrugated Metal Roof?

Once your corrugated metal roof is installed, it’s essential to take good care of it to prolong its life. Here are a few tips for keeping your metal roof in good condition:

  • Keep the roof clear of debris, such as leaves and branches
  • Inspect the roof regularly for damage and repair any damage as soon as possible
  • Inspect the flashing regularly for damage and replace as needed
  • Hire a roofing specialist to inspect your roof annually
  • Make sure that you only use metal safe cleaning products when cleaning your corrugated metal roof

Can You Paint Corrugated Metal?

Yes. You can paint your corrugated metal roof to match your home’s exterior or the surrounding landscape. If you choose to paint your roof, it’s essential to use high-quality paint that can withstand the weather.

Do Corrugated Metal Roofs tend to leak more often? 

Corrugated Metal Roofs do not typically leak more or less often than other types of roof materials.

But if a strong storm or natural disaster occurs and a section of your metal roofing is ripped away, it can allow water into the interior of your home. This is why it’s so essential to hire professional roofers to install your metal roofing.

What is The Best Time to Install a Corrugated Metal Roof?

Although corrugated metal roofing can be installed at any time, it’s usually best to install the panels during the spring and summer.

This is because heavy snow and ice can cause damage to your new roof, and poor weather conditions could delay or disrupt the installation process.

Can You Walk On a Corrugated Metal Roof?

Yes, you can walk on a corrugated metal roof, but you should take caution when doing so. It’s essential to wear shoes with good traction to avoid slipping. You should also avoid walking on the roof during wet weather conditions.

Do Corrugated Metal Roofs Rust?

Yes, corrugated metal roofs do rust. If your home requires a new metal roof and its current roof is rusty, you should take precautions before installing the new roof to avoid spreading rust onto the new panels.

Is Corrugated Metal Roofing Recyclable?

Yes, corrugated metal roofing is 100% recyclable. In fact, many recycling programs will pay you for your old corrugated metal panels!

This means that you can recoup some of the expense of your new roof by selling your old metal to a recycling company. You should also check with your city or town to find out if they offer a metal recycling program.

Do Corrugated Metal Roofs Affect Wi-Fi or Satellite Reception?

Yes, when a metal roof is installed over your home’s existing roofing material, it may block Wi-Fi and satellite reception depending on how it is installed.

After installing a corrugated metal roof, you should hire a roofer to install a dome antenna to improve your Wi-Fi or satellite reception.

Is Corrugated Metal Roofing Fireproof?

No, corrugated metal roofing is not fireproof. If your home catches on fire and the flames reach your roof, it could melt or ignite.

This means that you should take additional safety precautions, such as installing a fire escape ladder, hiring security guards to patrol around your property, and installing smoke detectors, in case your home catches on fire when you’re not there.

Conclusion: Are Corrugated Metal Roofs Worth it? 

Corrugated metal roofing is a good option for homeowners who are looking for a durable, affordable, and energy-efficient roofing material. Corrugated metal roofs are also an attractive, modern option that can improve your home’s curb appeal. 

However, it’s essential to weigh the pros and cons before making a decision.

If you live somewhere where there is little to no snowfall, then the noise factor shouldn’t be too concerning. If you live somewhere with heavier snow, either opt for an ice and water shield to protect your roof against the weight of the snow or choose another type of roofing.

Talk to a professional roofer to determine if a corrugated metal roof is the best option for your home.
