Whether you are brave enough as well as skilled enough to attempt a metal roof cladding project on your own or plan to hire a qualified and experienced Canadian contractor, you need to follow this crucial checklist. Adhering to this checklist will ensure that your project gets completed without a hitch and your cladding lasts for several decades. First on your checklist should be to make sure that you do not end up installing steel and aluminum together such as using steel panels with aluminum flashings. You must make sure that you do not allow galvanic corrosion since several metals can react together and hasten the corrosion process, which in turn can defeat the whole purpose of installing a new metal roof on your home or commercial establishment.
The same holds true for fasteners too since they can also react adversely with various metals and wear out at a faster rate. Even if you do plan to install a cedar shake roof that has a lower lifespan as compared to metal, you can end up lowering that lifespan further by using products coated with zinc with cedar shakes or shingles. The presence of tannic acid in cedar can drastically affect zinc and cause damage within a short time. If you plan to use bonded sheet metal that contains a polyethylene core for your metal roofing project then you need to ensure that local building codes do not prevent installation of such composites above specific heights. You may need to use a different core material if you want to install the cladding above the specified height. You can opt for mineral based cores that are available in the market. In addition, you must also ensure that the materials used for your metal roof possess the best possible rating with regards to fire, wind, hail, etc., so that your home or office gets optimum protection during an unfortunate event. Thickness of the metal used for cladding is also an important factor that should be in your checklist. A dangerously thin gauge of sheet metal on your roof will not only result in oil canning, which causes waves on the metal skin, but can also result in structural weakness, which can lead to sagging within a short period of time in case the columns and beams are not designed to support such thin metal. Your checklist should also include all possible caulking material and other sealants that are proposed to be used during installation of your metal roof. For instance, you can opt to use butyl sealants instead of silicone ones since they are better resistant to heat. You need to consider exposure to heat, cold, UV rays, and rain before you finally decide on which sealants are best suited to your roof.
You should adhere to the above checklist so as to choose the perfect metal cladding and other associated components for your metal roof. You will be able to save a lot of effort, time, and money before, during, and after installation of your metal roof in Canada.
