Is Metal Roofing Lightweight

Is Metal Roofing Lightweight?

Is Metal Roofing LightweightYou likely haven’t put much thought into how much your roof weighs. But once you start to consider the question, it becomes obvious how important this detail really is. The roof is one of the largest features of your home. After all, it covers the entire house! Depending on the materials used in its construction, a residential roof on a 2,500-square-foot home can weigh as much as 50,000 pounds. That’s equivalent to having five full-grown African elephants up there.

Weight of Metal Roofs

Luckily, roofs come in many different materials – including our favorite, metal! On top of boasting environmental sustainability and energy efficiency, metal roofs also come in at the lowest weight among all “standard” roofing materials. Did we mention they hold up better than the rest of the materials too? The average weight of 100 square feet of different metal panels is as follows:

  • 45 pounds: aluminum shingles
  • 80 pounds: steel shingles
  • 120-150 pounds: steel standing seam

Cons of a Heavy Roof

A well-constructed home can easily support a roof weighing up to 50,000 pounds. However, the homes structural and support materials weaken over time. And if the weight of the roof is too much, the aging home is more likely to move and shift underneath it all. Extremely strong windstorms and, even worse – earthquakes, can wreak havoc with the structure of an older home. And in the event of a fire, a heavier roof is more likely to collapse and cause further damage. Now is also a good time to mention that metal roofs are also highly fire and flame resistant.

So why should you consider a light metal roof? Not only for the above benefits, but also for their durability, insulating properties, fire-resistance and their ability to keep looking great decade after decade Metal panels are a wonderful, eco-friendly, and long-lasting investment to make for your home.

Are Metal Roofs Ecofriendly

Are Metal Panels Eco-Friendly?

Are Metal Roofs EcofriendlyWe make decisions every day that contribute to our overall carbon footprint. Reusable bags at the grocery store or declining a printed receipt are some small steps we can take. But as home or building owners, there are even bigger moves we can make that have a larger impact. One such decision is building with metal panels. Whether you plan to use these panels for side cladding or for a roof, the sustainability benefits are the same. So what is it about metal panels that make them so eco-friendly? 

100% Recyclable

Metal panels contain a high percent of recycled materials – your wall cladding could have been a refrigerator or automobile in its past life. And when the lifecycle of your panels eventually come to an end, the material can be recycled yet again! When the service life of a metal roof ends (decades after installation), the material can be recycled yet again.

Energy Efficienct

According to data from ENERGY STAR, heating and cooling can account for up to 50% or more of a home’s total utility consumption. The use of metal roofing can help with energy efficiency through solar radiation reflection if you use unpainted metal, or by increased re-emittance of solar radiation with pre-painted or granular coating metal roofing systems.

Incredible Life Span

While recyclability and energy efficiency are great reasons to choose metal, the biggest reason people use this material is its long shelf life. Roof shingles have a life expectancy of 20 years; compare that to a metal roof’s expectancy of anywhere from 40 to 70 years. Not only does this save you money in the long run, but avoids asphalt shingles finding their way into landfills every 20 years.

Other Reasons

There are plenty of other factors that make metal panels eco-friendly. They are the perfect material for collecting rainwater thanks to their anti-microbial paint systems. They’re also able to shed large materials easily without the range of crevices and cracks for those materials to adhere to. Metal panels also have the highest strength-to-weight ratio of any regularly used building material, so they’re ideal for solar panel installation.

For these reasons and more, metal panels lend themselves to the best that sustainable buildings have to offer. Protecting the earth and your bottom line. Contact our team today to learn more. We will be happy to answer any of your questions at  1.855.838.9393 or info@londonecometal.com!

Lifespan of a Metal Roof

What is the Lifespan of a Metal Roof?

Lifespan of a Metal RoofIf you are considering making the upgrade to a metal roof, you probably have a lot of questions. Such as, can a metal roof withstand my local climate? How hard will a metal roof be maintained? Are there energy benefits to a metal roof? And perhaps the most important – how long will this investment last me? Good news! Metal roofs are known for more than their good looks; they are also known for their long lifespan!

So What Is The Expected Lifespan of a Metal Roof?

When it comes to the lifespan of traditional roofing materials, metals are unrivaled in their longevity. In fact, the majority of metal roofs can often last 50 to 100 years with the proper care and maintenance. Compare this to other asphalt shingles, which last between 10 and 20 years. And homeowners can rest easy knowing that when the gig is up, their metal roofs can be 100% recycled.

What Factors Contribute to the Lifespan of a Metal Roof?

  • Metal roofs are better able to withstand the slight contraction and expansion that comes with changing temperatures. Because of this adaptability, they are far more durable than conventional roofing materials. They also have the highest impact resistance and hail rating!
  • Metal roofs are not susceptible to cracking and crumbling when exposed to high UV like shingles are.
  • Thanks to their overlapping construction and protective sealant, metal roofs are far less likely to experience water damage compared to other roofing structures. 
  • Metal roofs are unattractive to pests, such as termites. Making them far less exposed to outer factors that would challenge the roof’s integrity.

Ways To Ensure Your Metal Roof’s Longevity.

Ensuring the longevity of your metal roof is easy with proper care and maintenance! You should clean your metal roof at least once per year, but ideally after the change of each season. Don’t forget to clean gutters, drains, and other debris from the surface of the roof. Structural maintenance is also important, albeit a bit more in-depth. You should have your panel seams inspected at least once per year and make sure areas in need of new/more sealant are attended to.

Metal panels are a wonderful, eco-friendly, and long-lasting investment to make for your home. If you would like to learn more about your metal roofing options, contact our qualified team of professionals at 1.855.838.9393 or info@londonecometal.com.

Do Metal Panels Trap or Repel Heat?

“Will a metal roof or panels make my home hotter?” One of the most common questions we receive as metal roof contractors. With an answer that surprises many homeowners, as a metal roof can actually help make your home cooler! This is due to two separate factors: the metal material and finish, as well as the construction or assembly of the structure. Let’s dig deeper to find how metal panels trap or repel heat.

Material Matters

Different metals conduct heat differently. You could, for example, have a roof made entirely of copper. A totally copper roof would be an excellent conductor of heat. Stainless steel, on the other hand, is a very poor conductor of heat. On top of the material, both the color and finish of the metal will affect its heat absorbency and retention. So yes, a metal roof will certainly heat up when exposed to direct sunlight. But throw a reflective finish on the panel and you have a far cooler roof than asphalt.


While the material and color will certainly affect the amount of heat collected by your roof, the biggest contributor to heat transferring to the home below is the type of construction between the roof and the home. How well that room ventilates plays an important role in controlling the ambient temperature. Once proper ventilation is established, ceiling insulation should be considered. The more there is, the less will be conducted into the room below. To help keep your home cool, some metal roof installers will include above sheathing ventilation (ASV). This system allows air to flow between your roof sheathing and the insulation, then get released. That means less heat energy is absorbed by your home.

Metal roofing is one of the most energy efficient materials available to homeowners and can help lower the energy used to cool off your house. Instead of absorbing all the sun’s heat, metal works to keep the hot air out, which in turn reduces how much air conditioning you need.

So there you have it! With proper installation, metal panels or roofs can keep your home cooler as opposed to trapping heat. Wondering if metal panels are suitable for your next project? We will be happy to answer any of your questions at  1.855.838.9393 or info@londonecometal.com!

Your next step is choosing a start date and voila! You will soon be preparing for your new metal roof installation. Wondering if we can help with your  next project? We will be happy to answer any of your questions at  1.855.838.9393 or info@londonecometal.com!

Selecting Metal Roofing Trim

How To Select Trim For Metal Roofing

Selecting Metal Roofing TrimYour roof does so much more than protect your home from the elements. Your roof is the cherry on top, the final piece of the puzzle, and the detail that can make or break your home. While you are familiar with the varying colors, textures, and finishes available for your overall roofing structure, the trim may have escaped your mind. Don’t forget about the gables and eaves either! These smaller, but still pertinent details, play a major role in how your home looks. If you want your home to look its best, keep these factors in mind when selecting trim for your metal roof.

Your Home’s Exterior

Consider your home’s exterior. All the way from the doors, to its siding to its windows. Even consider the landscaping. You will notice that your home has its own unique, distinct sense of flair. The roof, trim, and all the little bits in between should enhance and compliment these details.

Your Desired Look

Remember that colors can be combined to influence perceptions. For example, selecting a trim color that complements your home’s siding can give your home a vintage feel, where the color scheme is reminiscent of the past. On the other hand, choosing a trim color that is in contrast to the palette used across the rest of your home lends itself to a more expressive, creative, and attention-grabbing appeal. You can also choose colors that look like metal, such as platinum or slate gray. These can give your metal roofing trim a fashionable, trend-setting appearance.

Energy Efficiency

Metal roofs deliver long lasting beauty and performance, while simultaneously saving on energy costs. Metal roofing utilizing cool colors are known to have energy savings ranging from 7%-15% of overall cooling costs. Because more heat is reflected, energy bills are lowered. Cool painted metal roofs also retain 95% of their initial reflectance and emittance over time. Equaling a longer lifespan over conventional roofing systems. When choosing your trim, you may consider these cooler colors as well.

Metal Roofs In Canada

Are Metal Panels Suitable For Canadian Climates?

Metal panels have unbelievable strength and high-performing characteristics. But you may be wondering if that means they can withstand the harsh Canadian winters. Whether you live in the rugged mountains or own a second home in a dry desert, we’re breaking down exactly how metal will perform in any climate. 

High Precipitation Climates

A leaking roof is a homeowner’s worst nightmare. No matter if you have to replace or simply repair a leaking roof, it’s going to cost you time and money. If you live in an area that experiences high amounts of precipitation, metal can be one of the best roofing solutions for you. Metal panels shed water like a pro, and don’t retain any moisture.

High Wind Environments

Some areas are prone to wind more often than others. If you live in an area with frequent high-speed winds, roofing and siding can be tricky. Less sturdy materials, such as shingles, can lift and fly away. Damaging your home and others. Metal is a structurally sound solution that can easily hold up well in windy conditions.

Heavy Snow Environments

Heavy amounts of snow over a short period of time can cause extra stress on your roof. One of the biggest concerns with heavy snow loads on a roof is protecting a home’s moisture barrier. As snow slightly melts, it will refreeze on your roof before sliding off. While this happens, it’s crucial your roof is able to maintain its moisture barrier. Luckily, metal roofs are designed to hold and withstand heavy snow loads. Metal panels are also significantly lighter weight than asphalt shingles, so the added extra weight of snow doesn’t add as much extra stress on your home.        

Hail Prone Environments

Hail can be detrimental to your entire roofing system, and your budget. While there is no 100% hail proof roof, metal panels come pretty close in terms of hail resistance. When it comes to a metal roof’s best defense against a hail storm, the thicker the metal the better.

How Are IMPs Made

How are Insulated Panels Made?

How Are IMPs Made

Insulated Metal Panels (IMPs) are climbing the ladder of top construction materials. Their superior insulating properties, increased spanning capabilities and single-step installation make them efficient and cost-effective. Combine that with the assortment of colors, widths, profiles and finishes. Making them the perfect choice! So how are these superior building materials made?

What’s In The Middle?

In the most basic terms, IMPs are comprised of rigid insulation sandwiched in between metal skins. Based on the manufacturer, that insulation material varies. The most common filling is expanded polystyrene, but IMPs can also use extruded polystyrene, polyurethane, and other materials. Different fillings have different performance properties. Some are better insulators while others are more structurally sturdy. This also leads to variations in thickness.

Bind It Together

Oriented strand board (OSB) tends to make up the outside of the panel. That being said plywood and fiber cement board are also common. Manufacturers apply structural-grade adhesives to stick these outer pieces to the insulation using machines called roll coaters. The machines apply glue from the bottom layer up, starting with a single sheet of OSB lying flat. The foam core is then placed into the adhesive, followed by another coating of glue on the foam core, and then the top layer of OSB is added.

Turn Up the Pressure

The adhesive has a tendency to expand. In order for the panel to stay together, manufacturers must press the entire piece together using a large machine.

Trim the Excess

Initially, IMPs are much larger than what we see on the construction site. IMPs must be cut to fit the custom shapes and sizes determined by the architect. To finish each panel, manufacturers can add connectors, create joints, or close off the exposed edges with a thin strip of OSB.

Long story short, IMPs are formed by a continuously poured-in-place manufacturing process that binds interior and exterior steel facings to a Class 1 foam plastic insulation. But these panels are so much more than that! IMPs are a beautifully strong and thermally efficient metal cladding product. They are readily available, easy to install, and every day designers are finding new and exciting applications for this dynamic and versatile building product.
