One of the reasons that many companies choose corrugated metal roofing for their buildings is the cost. This type of roof is very durable, long lasting, safe from all kinds of weather (even thunderstorms!) and is very inexpensive to install. Most business buildings have been using this type of roof for a very long time but not too many private homes considered it due to its not so attractive appearance.
More and more, private home builders are starting to consider using corrugated metal roofing because of the cost to longevity ratio. Some cottage homes and many apartment buildings with flat roofs have been using this for years now. One thing you should consider when using it on a sloping roof where you get snow is that, this being a very slippery material for water and melted snow, when the snow starts to melt the entire load of snow may slide off all of a sudden like hitting the deck with an avalanche of snow. This alone is not such a big deal if you’re aware of it, but the fact that this could often take down vents and in some cases your chimney with it, is a valid concern.
You could, of course, build your roof in a way that would protect you from this type of problem. Often using corrugated metal roofing is done on flat to semi-flat surfaces but it can be use in any format. You could also lay tar over the metal and create a plywood layer where you could add a layer of shingles for both the look and extra insulation. One problem with metal roofing however is that it rusts pretty easily and although it will last a very long time, this rust could damage the way it looks making your home look older than it is. It would also make it harder to sell your home later if you wanted to do that so it may be better to go with an option other than a metal roof.
You can find a lot more information on corrugated metal roofing online. Many sites that sell this type of roofing material will have information on what types of homes this can work with, how to install it, and what you will need to know before making the decision. You can find many other sites that aren’t associated with sales of the material, that will give you some tips and further explanations of what’s involved in the decision process as well as your other choices.
