To state the obvious, Alaska gets pretty cold during the winter. It only makes sense that, when you’re re-roofing your business, you’ll want to select a material option that will help you better insulate the building and keep the warm air inside where it belongs. This will save you some significant money in your heating expenses over time.
Commercial metal roofing in Alaska is known for having excellent reflectivity, which helps on sunny days to bounce the sun’s ultraviolet rays away from a building and keep the inside from getting too warm. But during the winter months, could this reflectivity end up being detrimental, and make the inside of your business colder?
Here’s some information to consider.
Research indicates metal roofs give you year-round consistency
The U.S. Department of Energy has actually looked into this issue before, and in a 2007 study, a laboratory provided some interesting insight. In the study, it was determined that asphalt shingle roofs stayed within five degrees of the temperature of a metal roof over the course of three nights in January, with the metal roof being a few degrees warmer during the day and a few degrees cooler at night.
The study also focused on the temperature of the air space under the roof. The sheathing below the asphalt shingles consistently followed the patterns of the surface temperature, dropping as much as 15 degrees below the outside temperature. However, the air space under the metal roof never fell below the outside temperature at all, meaning that while the surface temperatures of metal roofs and asphalt shingle roofs were essentially the same, the air space below the metal roof would at times be significantly warmer during the winter months. The metal roofs were losing only about half as much heat as the shingle roofs at night in the winter.
Obviously, this makes a significant difference, not just in comfort level but in the amount of energy you have to expend on heating (and thus the amount of energy you have to spend on your utility bills). Of course, this also assumes your roofing has been properly installed—you need to use the right types of underlayment to create less heat transfer (a synthetic roof underlayment is generally the best bet), and you need to make sure the metal roofing panels themselves have been installed and sealed properly. Low-quality installation can result in the roofing not having those insulating benefits that you might hope for.
So, in taking all this into account, you can safely assume that commercial metal roofing in Alaska is actually the best bet for your home or business in cold-weather climates.
