Did you know that Southeast Michigan has recorded snowfall of over three inches as late as May? While it has been nearly 100 years, residents in the area should not be surprised considering how late in the year snowfall regularly occurs.
With more than 41 inches for the year on average, the roofs above our heads can take a beating. Fortunately, with the right precautions in place, proactive homeowners can take some steps to ensure their roof is protected against the effects of snowfall while protecting other parts of their property as well.
Just a few additions or tweaks to your existing roof can go a long way to preventing issues due to snow.
Thawed Snow Can Mean Frozen Eaves
A lack of sunlight and freezing temperatures combine for keeping snow around, which creates a damaging effect to parts of your roofing system. This begins with air from within your living space rising and then warming the roof at its highest points.
Water from the thawed snow then begins to make its way down your roof, but eventually refreezes when it gets to a colder section of the roof—typically near the edge. These “ice dams,” as they are called, can cause damage to the roof underneath them and create a situation in which further snow melt may seep under the shingles.
If the roof is not thoroughly sealed throughout its entirety, this water can eventually make its way into your home. The expanding and contracting effect of freezing and thawing water allows moisture to get into spaces previously closed off.
Local Roofing Contractor Keeps Your Roof Protected
The best way to avoid this situation is to have a roofing contractor come inspect your home and determine any need for repair. This repair may involve further insulating the attic or installing ventilation. Keeping gutters and downspouts clean also lessens the risk of ice formation around the edges of your roof.
Another reason for a roof inspection this time of year is to determine your roof’s capacity for keeping snow from causing a roof collapse. Wet snow and wind are disastrous when they work together to form heavy drifts on a roof.
Roofs that are over stressed will crack, leak, and cause ceilings to sag.
