Here in Southeast Michigan, we are, to put it mildly, no strangers to winter weather. No, we don’t get the truly epic snowfalls of the U.P., but Old Man Winter—whose arrival is just around the corner—can pack plenty of punch in the Rochester Hills, MI and greater Metro Detroit area. And that “punch” can do a number on your home, not least when it comes to your roof.
As trusted providers of home insurance, the team here at Guy Hurley McNeil has some insights into winter roof problems.
Common Winter Roof Issues in Southeast MI
While much of our wintry precipitation takes the form of benign flurries, light snowfalls, or simply rain, we can also be on the receiving end of burlier snowmakers courtesy of “Alberta Clippers” and other strong low-pressure systems as well as, under the right conditions, significant lake-effect snows. Ice storms and freezing-rain events also certainly aren’t unheard of here, and these can be just as problematic as a multi-day blizzard.
Snow Load
Heavy snowfall or simply a prolonged period of regular precipitation and cold temperatures can build up a significant snow load on your roof. And a thick snow layer (or even a modest amount of wetter, and therefore heavier, snow) can absolutely result in excessive strain on and damage to your roof—even, in extreme cases, roof collapse.
Building codes generally specify a snow load for our area of 25 pounds per square foot (psf). Major blizzards dropping a lot of snow over a short period of time, not to mention “rain-on-snow” events or rapid thaws that add a lot of water—and thus weight—to your roof snowcap, have the potential to exceed the designed-for snow load and increase the risk of structural damage.
Ice Dams
Another common malady in Southeast Michigan is the dreaded “ice dam.” Ice dams form when heat from your upper levels or attic escapes (due to inadequate insulation or seals) to the roof, thawing out part of its snowcover. That meltwater then drains downslope and freezes upon encountering the colder air around your roof eaves, forming a shelf or rim of ice.
That then becomes an effective dam, forcing the snowmelt coming off the upper part of the roof to seep under shingles or roof panels to leak inside and cause water damage.
Preventing Winter Roof Problems & Safeguarding Yourself
Regular inspections of your roof can help you identify damage, weak points, and other concerning spots that may be vulnerable to excessive snow-load strain or meltwater leakage. Acquiring a good roof broom or rake to sweep off snow can help you manage your roof’s snow load. And shoring up your insulation, making sure seals around chimneys and the like are sound, and clearing or installing soffits and vents for better air circulation and consistent temperatures around the roof can help you avoid ice dams.
