How Your Home Climate Affects Your Roofing Choice

You can change your roofing, but you can’t change the weather.  No matter where you live, you and your home are affected by climate.  A region’s climate is determined by many factors, the most important of which are its typical temperature, dryness, and weather. 

Let’s take Tampa, Florida as an example.  Tampa enjoys a humid subtropical climate with an average temperature of 73.35° F and an average humidity of 74%.  That intense humidity has the potential to aid in the growth of unwanted plants on your roof.  However, metal roofing resists the growth of unwanted plants like algae, and other tropical weather weeds, keeping your home looking well-maintained and attractive. Whereas other options such as asphalt roofing need to be treated to protect against algae, metal roofing does it naturally.

Moisture in the air in a tropical climate also lends itself to a familiar yet unwanted plague: rust.   It may seem counter-intuitive to decide on a metal roof when concerned with the possibility of rust, but there are metal options that are both rust-resistant and waterproof.  These features, coupled with metal’s natural ability to prevent anything you don’t want from growing on your home, make it a great roofing choice for a tropical, warm, or humid climate. 

Now let’s take a trip up to the coldest state in the continental U.S.: North Dakota.  The capital, Bismarck, only experiences an average annual temperature of 42.8°F and has to withstand 50 inches of average annual snowfall.  This may sound a little different from balmy Tampa, but metal roofing is just as suited to North Dakota’s freezing cold as Florida’s burning hot.  Colder climates mean harsher winters, and harsher winters mean harsher weather.  In terms of longevity, a metal roof is the best option bar none.  Traditional asphalt roofing has a lifespan of only about 12 to 20 years, meaning you may have to replace your roof several times in the course of only a few decades, a chance that only increases as the weather gets worse.  Metal roofing is widely agreed upon as being the most durable and long-lasting roofing choice, with a life expectancy of 40-70 years, depending on the exact material. 

Metal roofing is suitable for all climates, however some regions, like those with colder and tropical climates, may not only find metal roofing preferable, but necessary.
