Around your neighbourhood, you may have noticed that more houses are having metal roofs installed. Even though it is a costly job, metal roofs are becoming a popular choice for residential and commercial establishments. They are long-lasting, environmentally friendly, and can withstand harsh weather conditions. If you’re looking for a roofing solution that will last for decades with little maintenance, then a metal system may be right for you. Here are some factors that affect the cost of a metal roof replacement:


The roof panels.

Metal roofs offer a variety of options to suit your aesthetic preferences, such as interlocking or overlapping panels. Different materials are offered at varying price points, depending on the durability and aesthetic you are seeking. We’ve listed some options for metal roof materials to give you an idea of their advantages and disadvantages:


Standing seam metal roof. Composed of either steel or aluminum, this roof is incredibly durable. Vertical panel metal roofs are ideal for climates with extreme temperatures since they won’t contract or expand when cold or hot. Standing seams have the highest cost, but can be applied on top of asphalt shingles. 


Steel roof panels. Those who like the design of interlocking panels will enjoy steel roof sheets. They’re made of high-quality material that can withstand acid rain and heavy precipitation. Due to their design, they will not be damaged by high wind speeds.


Aluminum roof panels. Commonly used for residential buildings, aluminum roofs are incredibly energy-efficient. Reflective pigments in the paint release heat and reduce your cooling costs. A PVDF coating seals the metal so it’s strong for years to come. If your home  or commercial property has a tar and gravel roof, aluminum panels can be installed over top, which will save on demolition and disposal costs.


Economy metal sheets. While this option requires more maintenance than others, it offers the lowest price point. Made of a steel alloy, this material is great for commercial buildings or agricultural use. 


The size of your roof.

As you already know, the square footage of your roof will play a role in the cost of replacement. A bigger building requires more materials and labour for the job. A small house will cost less for a roof replacement than a large commercial business. 


The slope.

Is your roof flat or sloped? The angle of your roof plays a factor in determining the price of a replacement. A roof with a steep incline makes the installation more complicated and will have a higher labour cost. Since sloped roofs can be difficult to walk on, special equipment may be required. For flat roofs, a contractor must consider other variables, such as the shingles needed, sealant, and fasteners. 


Design of the panels.

Does your roof of choice feature interlocking or overlapping panels? Designs with panels that overlap come at a lower cost. Interlocking panels offer a better quality finish, but require more labour to manufacture because of their structural detail.


Other options.

Metal roofs aren’t for everyone. Transcona Roofing also offers single-ply membrane systems that can offer durability with a pleasing appearance, and without the high price point of metal roofs. EPDM, or ethylene propylene diene monomer, is made of synthetic rubber. It’s fire resistant and energy efficient. This thermoset membrane is ideal for Winnipeg winters, since it won’t crack in the cold. Yet another option is a thermoplastic membrane; these include TPO (thermoplastic olefin) or PVC (polyvinyl chloride). Flexible and versatile, a TPO membrane is ideal for low sloped roofs. It reflects UV rays, making it a great choice for energy savings. Finally, a PVC roof is a more expensive membrane, but it offers increased chemical resistance. It’s also the most flexible option. PVC roofs are suitable for homes that endure extreme weather conditions. 


Are you considering a metal roof for your home? There are a few other factors that will affect the final cost. For one, there is the thickness of the panels - more material means more expenses. The coating is another consideration; it will protect the substrate and enhance its strength. PVDF coatings have the longest lifespans and best fade resistance, while polyester paints are more affordable, but with less endurance. The climate of your location will impact the labour costs. Finally, to install a metal roof, you’ll want to hire a contractor with specialised training for the job. We can also assist you with evaluating whether you would prefer a membrane like TPO, PVC, or EPDM. The contractors at Transcona Roofing have the certifications and experience to install these systems.
