With the frigid temperatures here in Minnesota and Wisconsin, there are some additional steps that should be taken when installing a metal roof to make sure it lasts as long as possible. Following the below recommendations for your metal roof will not only ensure fewer problems during the adverse winter conditions but will also save you time and money in the long run.
Color not only has an aesthetic value but also plays an important factor in solar absorption of a metal roof, which helps the snow and ice thaw and melt. Choosing a darker color rather than a lighter one will help with this dramatically.
Consider your surroundings and take into account any large trees that will provide shade for the roof. Such foliage causes extra snow accumulation and in some cases, ice damming.
Snow Bars or Guards
Snow bars or guards are devices that will allow the snow and ice on your metal roof to fall off in small amounts or even melt completely before falling to the ground. Their main purpose is to prevent the sudden release of snow and ice from your roof known as a roof avalanche. This is a very serious issue and could cause damage to anything below your roof in its path such as your gutters, plumbing vents, cars, pets or even a person if they were standing in the right spot when it happens. The areas you want to be most vigilant and consider installing snow bars or guards are high traffic pedestrian areas such as doorways and parking areas.
Roof Decking & Underlayment
If you are installing a metal roof on your home or garage you will already have a roof deck, but if you are installing on a post-frame building you may not. We recommend always having a roof deck installed so there can be an underlayment applied for ice dam protection.
You Want a Cool Roof
A “cool roof” is essential when installing one in the cold climate of Minnesota or Wisconsin. You want your entire roof, including the eaves, as ventilated as possible and are very well insulated. Be sure to check there are no leaks that could occur.
