For decades, metal roofing was presumed to lack aesthetic value for residential homes. Thanks to technological development, metal roofing is steadily gaining popularity in residential use.
If you are planning to install a metal roof but you still have concerns, this article will highlight metal roofing pros and cons. We will also highlight facts about metal roofing and debunk the most common myths.
Metal Roofing Pros and Cons
Metal roofing, also known as the forever roof is a superior choice compared to other roofing materials. It has numerous benefits which make it rank top among many types of roofing materials. It also has a few limitations which can easily be mitigated to enable you enjoy the many rewards from metal roofs.
Pros of Metal Roofing
Extreme longevity and durability
If your metal roof is well installed and cared for, its expected life span is 40 – 70 years – same as the house. Additionally, metal roofing does not require costly, routine maintenance.
High fire resistance
Since metal roofing materials are noncombustible, metal roofs enjoy Class A fire rating, the highest fire resistance rating.
Compared to other types of roofing materials, metal is very light. You can apply a metal roof on top of an existing one without additional structural support.
Metal reflects the sun’s heat which saves energy by using your cooling system less. You can also utilize the air space between the roof deck and the metal for more energy efficiency.
Minimum roof pitch
A metal roof can be installed on your gently pitched roof without the risk of leakage. A low roof pitch typically has a 3-inch rise for every horizontal foot.
Utmost shedding of snow and rain
Metal roofing panels are hard and slippery, and are installed by interlocking which makes them impermeable to rain or snow. Additionally, dark-toned metal roofs warm fast and cause snow to melt.
Metal roofs are 100% recyclable and contain a minimum of 25% recycled materials. They also provide an ideal platform for eco-friendly initiatives such as rainwater harvesting and the use of solar panels.
A wide variety of style options
You can choose your metal roofing from a variety of materials and an array of colors, shapes, and finishes. Metal roofing offers over 100 colors in custom, premium, and standard hues. It also comes in styles that mimic nearly all other roofing materials.
Fungus and moss-proof
Metal roofing is 100% resistant to moss, fungus or mildew. If you live in a heavily wooded area prone to the growth of moss, a metal roof is a perfect choice.
Resistance to wild animals, pests, and rodents
Once you install a metal roof, you can be certain that pests and rodents cannot damage your roof or gain entry into your attic.
You can adapt your metal roof to your home design. There are metal roofing products that suit your intricately arched or rounded roof.
If you use another roofing material, you must combine it with sealants to cover transitions, dead valleys, and flashings. On a metal roof, you can flash these difficult areas using matching metal, which is more reliable than adhesives and sealants.
Traditional roofing materials change style and color frequently making it difficult to match if you modify your home. Metal roofing manufacturers maintain consistency in colors and designs, helping you add or modify your roof later.
Cons of Metal Roofing
Metal roofing has got a few cons that you may want to consider before installing your preferred style of a metal roof.
The initial investment in metal roofing is considerably high. However, the durability of the roof balances the installation costs.
Damage by extreme weather
Although your metal roof is hail resistant, major hurricanes can damage it. The upside is that Toronto does not experience extreme weather. Your metal roof will remain intact for a lifetime.
Longer installation time
The installation of your metal roof will take longer due to the specialized training, knowledge, equipment, and tools required. It will also take longer for your roof to be carefully flashed to match your roof configuration.

Common Myths About Metal Roofing
With increased discussions about metal roofs, there is an increase in the number of myths being propagated. Let us debunk some of these common myths.
Myth: Metal roofs prevent ice dams
Ice dams form when your attic is not properly insulated, or the ventilation is inadequate. Heat rises, the snow melts and flows to the eaves where it refreezes – even on metal roofing.
Myth: Metal roofing will lower heating bills
If your home has air leaks, inadequate insulation, and no energy efficient windows, metal roofing will not lower your heating costs. Your home’s overall energy consumption is based on many factors, not just the roof type.
Myth: Metal roofing offers no resale value
Metal roofs are highly valued. Nationally, standing seam metal roofs recoup between 85 – 95% of costs. This translates to a rise in resale value by between 1 – 6 %.
Myth: Metal roofs are noisy
Generally, metal roofs are quieter than asphalt roofs. Metal roofs have an underlayment with solid sheathing installed to help reduce noise. Even when it rains, metal roofs are not louder than other roofs.
Myth: Metal roofs attract lightning
Installing a metal roof does not increase the chances of a lightning strike on your house. Lightning often strikes the tallest object. A metal roof is also safer due to its noncombustible nature.
Myth: Metals roofs cause extreme cold in winter
Your metal roof does not affect the temperature of a well-ventilated attic. The insulation on the floor of your attic keeps your house warm.
Myth: Metal roofs rust
Metal roofing is designed to maintain its original appearance for a lifetime. Your metal roof will only rust if you want a slowly and distinctively rusted natural steel.
Myth: Hail damages metal roofs
Unless the hailstones are extremely large, normal-sized hailstones cannot damage a metal roof. Even under unusually large hailstones, minor denting is almost invisible on textured roofs.
Myth: Metal roofs function poorly in extreme conditions
Among all roofing materials, metal roofing performs best in harsh weather conditions. Your metal roof can withstand storms and hold up under ice loads and heavy snow. It is also an excellent choice if you live in areas prone to wildfires.
Myth: It is less sustainable than other materials
Metal roofing is recyclable and energy efficient. A quality coating on your metal roof makes it naturally resistant to fungus and moss. You, therefore, do not need chemical treatments that are an environmental hazard.
Myth: Metal roofing has limited style and color
Metal roofing is available in numerous design and color options to fit an architectural design of your choice. It imitates the appearance of slate, shakes and clay tiles but with extraordinary performance and durability.
