When deciding on installing standing seam roofing, it is not only practical aspects of the job, such as learning how to install a metal roof, or more about residential metal roofing applications that are a factor. Aesthetics and the visual appeal of the roof with your house are also very important.
Not only do roofing finishes affect the aesthetics, but depending on the coating or material you choose when installing your metal roof, you will either get more or less years of service from it. Here are a few finish options explained.
If installing standing seam roofing with a galvanized finish, you are choosing a mild steel substrate, with an electro-galvanized finish. This means that the sheeting is coated with a thin layer of zinc, which is bonded to the sheeting.
Suitable for installing standing seam or other metal roof sheeting that is not near the coast, this option does not hold up well under marine or industrial conditions, so avoid it if you live near the sea, or in an urban area with a lot of pollution!
Similar to galvanized sheeting, zincalume coating is a mixture of zinc and aluminum, bonded to a mild steel substrate. This type of coating holds up much better under tough marine and industrial conditions, and many manufacturers offer a longer warranty on the sheeting.
Aluminum sheeting is much more costly, but since it is non-ferrous, rust is not a problem. For residential roofing applications where a very long lifespan is a requirement, or even commercial or industrial application this is an ideal choice, if you can afford it.
Some sheeting manufacturers will be prepared to roll special orders, based on larger quantities, in metals such as copper. The cost is usually higher, but these other metals can create a unique visual appeal, and may offer superior corrosion resistance. Check with your supplier whether they offer any unique metals.
While you can opt for a plain galvanized, zincalume or aluminum sheeting, you may decide, when installing standing seam sheeting or other metal roofing, to opt for pre coated options.
These coatings are bonded to the coated base metal using a heat process, similar to powder coating. Metal roof colors vary from supplier to supplier, but there are a large variety. In addition to offering a better aesthetic, these metal roof colors are usually guaranteed for some time, providing the metal roof installation instructions of the manufacturer are followed.
Instead of, therefore, having to paint your roof, if you desire a color finish, every few years, you may get ten to fifteen years of trouble free, color coated service.
When installing standing seam roofing, or other roof sheeting, and choosing a finish option, it is worthwhile to consult the manufacturers or a roofing professional, to find out how to install a metal roof properly, and pick up some metal roof installation tips. Getting it wrong can void a guarantee – so exercise caution!
