Worried About Residential Roofing Damage From Snow And Ice?

Do you know which months Massachusetts residents see the most snow? Climate data research shows that January (12.9 inches), February (10.9 inches), and March (7.8 inches) are the three most likely months for the largest snowfall. So, how does your rooftop hold up when the flurries build up so quickly? Here are a few things you need to worry about during a winter snowstorm.

How Much Is Too Much Snow On A Roof?

In general, a roof can hold about twenty pounds of snow per square foot. For every five inches, it equates to about two-and-a-half weighted pounds on your roof or 3.3 feet of snowfall build-up.

Can Snow Damage Your Roof?

Snow affects a building both interiorly and exteriorly. As the roof builds up, it creates structural pressure on the roof, which can cause a cave-in over an extended period of time. The attic is also heated and causes the snow on the roof to melt. During colder night temperatures, the wetness refreezes and causes ice dams to form on the shingles and gutters causing irreversible damage.

Should Snow Be Removed From A Roof?

If your primary goal as a home or business owner is to keep your roof in optimal shape, maintenance best practices recommend cleaning off the snow before it exceeds a half-foot. If you only want to promote safety, you can simply provide maintenance by raking your roof at a maximum of a foot of snow build-up. If you intend to hire someone, do not rely on a snow removal company to perform this service as they can easily damage your roof and shingles.

How Do I Stop Snow On My Roof?

You should use a roof rake to remove snow and ensure that ice dams do not form. You can also properly insulate and ventilate your attic as it will prevent snow from forming on your roof. You can also add protective coatings and sealants to prevent weather-related cracking and breaking.

What Is Ice Damming On A Roof?

Ice dams are formations on the roof from melted snowfall that prevent snow from melting and entering the gutters on the roof for proper removal. Any water will simply connect to the formed dam and make it larger. Over time, it will cause shingles to crack and break off.  Ice dams also tend to freeze inside the gutter and cause blockages that lead to improper disposal and flooding.

Water trapped on the roof can also cause leaks to occur through flashing, which causes structural damage, attic leaks, and ceiling instability. It’s an ideal time for residential roofing maintenance.

How Do You Know If Your Roof Is About To Collapse?

Exterior weather damage is the most vital factor in roof damage. You’ll know your roof is about to collapse if you see a saggy roof, interior leaks, roof support bending or swelling, and door or window misalignment. You’ll also notice cracks begin to form in the masonry, drywall, and ceiling. If you have an attic, you should also check the roof joists to see if they are damaged.

Does Insurance Cover Ice Damage To A Roof?

Insurance agencies generally cover weather-related roof damage, including snow and ice. If ice dams are present, homeowners may be responsible for removing them before repairs are done.
