CAMPAIGN: Ethical and Sustainable Living


Whether it’s time to replace your existing roof or you’re thinking about upgrading your home in the future, chances are you haven’t heard all that much about metal roofing. Although wood and asphalt shingles are the most popular materials out there, they pale in comparison to the benefits a metal roof can provide. Unmatched in longevity, durability, and cost-effectiveness, metal roofing is also gaining popularity for its myriad eco-friendly benefits as well. Below, we’ve listed the four biggest advantages to installing a metal roof, and why this is one upgrade you seriously need to consider during your next home renovation.

1. Recycled and "Over the Top" Installation

Metal is the most eco-friendly roofing material on the market, for a whole host of reasons. Firstly, most metal roofs are made from recycled material, and they can be recycled again at the end of their lives. They can also be installed over your existing roof, which cuts down on waste and minimizes installation time. There are also fewer emissions released in the production of metal roofing, and its light weight reduces emissions released during transport as well.

Finally, metal roofing can have up to 95% solar reflexivity, which means it’s dissipating heat from the sun more efficiently — especially compared to the 5% reflexivity of asphalt shingles. This means your home, particularly your attic, won’t over-absorb solar heat and get too warm, particularly in the summer. This means big savings on your energy bill since you won’t have to crank up the AC!

2. Extreme Durability

The lifespan of wood and asphalt shingles is about 15-20 years. While this may seem like a long time, it’s actually extremely short considering the lifespan of your house, plus the fact that both materials need frequent and costly maintenance in the interim. Metal roofing, on the other hand, can last up to 70 years or more, and the maintenance is minimal at best. In addition to being incombustible, metal roofing is extremely resistant to high winds, and its interlocking construction makes it virtually impervious to leaks and pests. Also, because of the slick nature of metal and its high reflexivity, a metal roof is the ideal choice for areas with heavy snowfall — the white stuff melts in no time, and any remaining buildup simply slides right off. So, if you’re tired of worrying about the health of your roof when the weather starts to turn, metal is an option you need to consider ASAP.
