How Snow And Ice Impact Your Roof

  • by

During the winter, your roof suffers from snow and ice. The heavy weight of snow adds stress and can make it vulnerable to damage. If snow already adds weight, imagine what ice can do. 

The roof is subject to caving with the accumulation of snow. Because rainwater flows to the lowest point of the roof, it can form large ice dams when the temperature drops. This will only increase the stress placed on it, posing a higher risk of cave-ins and damage.

Read on to learn about the impact snow and ice places on your rooftop and whether it’s time to contact roofers in Crofton, MD.

Ice damming in action

What Are Ice Dams?

If enough ice accumulates on the edge of the roof, it forms ice dams. Since there’s a slope in roofs, there is an uneven roof temperature. The top area is warmer than the lower edge, which causes the melting snow to freeze at the edge. When it freezes, it becomes a block of ice called an ice dam. 

Ice dams prevent snow from melting and draining down the gutters properly. Your roof can end up having puddles and eventually back up under the shingles. Once this happens, there are many other possible issues, like your home’s structure, mold, and more. 

They can even cause major gutter damage and even damage the flashing. You should find roofing contractors in Crofton, MD, to look at your roof’s stability.

What Does This Mean For Your Roof?

There are many ways snow and ice dams affect your roof. They can damage the shingles, insulation, drywall, and more. The weight can cave your roof in, requiring roofing companies in Crofton, MD, to replace it completely. 

Below are three ways snow and ice can damage your structure. 

  • Water Damage: As water piles up towards the edge of the roof, it can start to go up under the shingles. Once water enters underneath, it can soak into the protective covering and roof deck. It can go further, damaging your home’s structure, insulation, and drywall. 
  • Gutter Damage: If an ice dam breaks free and falls off the roof, it can damage the gutter system. The weight of it can cause gutters and downspouts to bend or twist. If your gutters are bent or seem to hang, have a roofer in Crofton, Maryland, come out to repair them.
  • Mold and Mildew: If the damp area is not dried properly, it can become the perfect condition for mold and mildew to grow. Mold and mildew can cause respiratory issues for anyone with allergies or sensitivities. If you see any spots that look like mold or mildew, have someone experienced with roofing in Crofton, MD take a look at your roof for any entryways.
