One of the biggest reasons people hesitate to call on metal roofing companies in Edmonton is the assumed cost. Unfortunately, architects and building owners alike have the same thought and forego a standing-seam metal roof altogether. That’s a downright shame since metal roof installation in Edmonton done properly can bring several benefits, such as:
- – Extended performance
- – Recyclability
- – Versatility in terms of aesthetics and functionality
That’s just the beginning, as there are many key benefits when metal is used for roofs and even walls for both retrofits and new construction. Read on to learn more about metal roofing’s economics:
Aesthetic and Functional Versatility
In terms of aesthetics, metal is able to bring on a more modern addition to more classic available roofing options. There are several commercial roofing options available that are on the more traditional end, including BUR (built-up roofing), mod-bit (modified bitumen), and single-ply.
Metal roofing has several advantages over all of them. Unlike most other materials, metal can get complex angles and tight curves going; there are also choices for textures and colours. Single-ply, mod-bits, and BURs can become vulnerable when they’re bending and can be downright rigid.
There’s a lot of malleability with metal panels, but they still manage to maintain the integrity of their structures. Metal roof assemblies are generally engineered on a custom basis. Whatever specifications an architect may have can be accommodated in the factory through panels being extruded or pre-formed. Customizing is particularly crucial for metal roof and wall’s waterproofing integrity to be long-term.
Contemporary design has a lot of curves, particularly dramatic ones. Metal is able to get this done with no issue; curves can go so far as to overlap, reverse themselves, fan out, extend, and more.
Extended Performance and Strength
Depending on where you are in Canada, the building functions, geographical conditions, and load requirements can vary. One of the key prerequisites for metal roofs and walls to last and have a good performance is a good wind uplift resistance. Many people end up thinking that the bare minimum testing standards for wind uplift resistance will do. That much is at least reasonable if this is being done in a suburban area-situated warehouse. However, for a high-rise building that generally has higher wind speeds, that will just not do.
Wind uplift resistance testing that metal assemblies must go through include:
- – ASTM E1592, Standard Test Method for Structural Performance of Sheet Metal Roof and Siding Systems by Uniform Static Air Pressure Difference
- – Testing Application Standard (TAS) No. 125, Standard Requirements for Metal Roofing Systems
- – Underwriters Laboratories (UL) 580, Tests for Uplift Resistance of Roof Assemblies
Some other things to note when it comes to metal roofs include:
- – Aluminum is ideal for preventing damage from salt spray environments that are very corrosive.
- – Exotic metals (copper, stainless steel, and the like) have ideal longevity.
- – Zinc has fungistat properties, preventing mildew and mould growth.
Conclusion
Many people tend to hesitate taking on metal roofs because of the cost. However, there are many advantages that make metal roofing well worth it. This includes aesthetic and functional versatility as well as extended performance and strength.
