Three Factors Of Your Climate That Dictate Whether Or Not Metal Roofing Is Your Ideal Roofing Material

Posted on: 21 May 2017

Many roofing manufacturers would have you believe that their roofing product, whatever it is, is the best one and ideal for your situation; however, there are several environmental factors that vary by situation and can make all the difference in which roofing product actually is the best for your roof. Some types of roofing perform better in warm climates than other types do, for example, and there are also weather factors that can cause problems for some types of roofing more than others. Here are three climate factors that will dictate whether or not metal roofing will make an ideal roof in your current situation.

Heat/sun factor:

The heat factor is an extremely important one, and yet it somehow manages to get more attention than it deserves. It's true that cool, reflective roofing materials can save money on cooling during the warmer months; however, this is offset somewhat by heat loss during the cooler months, so it's most efficient in areas of the country where most months are warm. This means the South. The further north one goes, the less effective this money-saving tactic is, and reflective roofing such as metal may even be able to lose money if you live in a place that's cold most of the year (and doesn't have complete snow coverage, since after all reflectivity is irrelevant if the roof is covered with snow).

Snow factor:

As mentioned above, the snow factor can affect the light and heat reflectivity of your roof. However, it also has consequences of its own. For example, the more heavy snowfall your area has, the stronger your roof has to be to carry it all. And this may mean that a "green roof" (aka one with plants growing on it) may not be for you if you live in an area with heavy snowfall. The plants and their growing medium add quite a load to the roof already, and if you're likely to get a heavy snow load in addition to that (plus the weight added by water soaking into the growing medium and then freezing there) it may become quite expensive to shore up the roof for that much load bearing. Metal roofing can be much better for these snowy climates because it has a certain degree of self-cleaning and snow-shedding ability.

Wind factor:

Hurricane season is a real threat all along the Eastern coast, and tornadoes can strike in any relatively flat areas in the country. Planning for strong winds is especially important if you live in an area that has strong hurricanes on a regular basis (such as more than once every five or ten years) or in a tornado-heavy area. If you are designing a house or even just replacing your roof with strong winds in mind, you'll definitely want to select metal roofing because it's considered to be the strongest and most wind-resistant material available. It doesn't rip off as easily as shingles and it doesn't crack like slate and tile when something is dropped on it (although it can of course become dented). 

Talk with a metal roof contractor as soon as possible to see if it's a good fit for your home.
