It’s not uncommon for parts of the Upper Peninsula to see well over 100 inches of snow a year.
But when does it become too much for your roof to handle?

William Bulleit is a structural engineering professor at Michigan Tech. He says, “The more complicated the roof the more difficult it is to decide what you should do with it.”

He says there are several factors that could put some roofs more at risk from snow accumulation than others.

For example, valleys in a roof or snow drifts on the top of your home.

There are things you can look out for that may be a sign there’s too much snow on your roof.

Bulleit adds, “Come winter time and there’s a lot of snow on your roof and your doors in your house are jamming in some places that might be an indication that the house has moved enough that you should take the snow off the roof.”

Cracks in the walls may be an indication, too.

Dan Perkins Construction out of Ishpeming specializes in metal roofing but he knows a lot about roofs in general.

He says when it comes to snow on roofs it can be hard to tell.

Perkins adds,”If it’s light it can go quite high and not weigh very much. If it got very wet and very dense it can weight quite a bit. A square foot of ice weighs 64 pounds. A square foot of snow can weigh anywhere from five to 50 pounds.”

Many of the businesses that offer the service of removing snow from roofs charge by the hour so as long as you’re from a safe place like the ground or in this case a balcony the more snow you can remove off your own roof the more money you’ll save.

It’s important to point out that removing snow can damage a roof so if you plan on doing it safely yourself be careful.

Perkins says, “If you touch the roof you’re scraping asphalt granules off the top of the shingles. If you’ve got a metal roof you could be scraping the paint.”
