Ice dams can affect your roof in various ways, from causing water damage to your property to heavy ice falls compromising exterior structures. It’s important to always monitor your roof during periods of snowfall and implement methods to mitigate the damage as much as possible.
How Roof Ice Dams Form
Ice dams form when temperatures close to your ceiling and roof are inconsistent. As you heat your home, your roof is laden with freezing ice. Pair this with poor attic insulation, and the heat will easily travel up and melt the ice on your roof. The melted ice runs down the roof to where it’s colder and freezes up, forming an ice dam.
Here is a step-by-step journey of how roof ice dams can occur on your roof:
- Your living area heats up, whether via a fireplace or another heating system.
- Due to improper or inadequate ventilation, this heat rises to the attic.
- It causes the snow on higher areas of your roof to melt and flow down the roof’s slope.
- As the melting snow reaches the eaves or overhangs, it refreezes due to the colder temperatures.
- The frozen water causes an ice block, known as an ice dam.
The Effect of Ice Dams on Your Roof
Ice dam roof damage can be significant if it’s left to seep under your shingles and into your ceilings and other structures, such as your drywall and insulation. Even if left on your shingles, the ice blocks can affect nearby people or objects if they fall.
Roof ice blocks can affect your home in the following ways:
- Compromise to roof shingles: As the ice begins to back up and eventually melt under your shingles, it could soak them and cause water damage and ceiling leaks. Signs that this may have occurred could be water spots on you ceiling during or after heavy snow and ice storms.
- Affects roof sheathing and deck: If left to soak, the moisture can seep into your roof sheathing, finding a way into your attic.
- Hampers attic insulation: Once the moisture from the melted ice works its way from the roof deck to the attic insulation, it can affect its performance. Damp insulation doesn’t work as well as when it’s dry.
- Can dampen and damage drywall: If the attic insulation does not provide optimal protection, the moisture can warp your drywall or cause the wood to rot. In some cases, it can also result in uneven flooring.
- Falling ice blocks can damage adjacent structures: Even if the ice dams don’t get a chance to seep into your home’s interiors, they can affect outside objects. Falling ice dams can bend and rip off your gutters and shingles, hurt pets or people or damage landscaping.
Roof Ice Dam Prevention
You can prevent ice dams from forming by regularly checking your roof and applying the proper maintenance. Remember that climbing on your roof is not advisable in icy conditions, so getting professional assistance is best if you’re unsure of what steps to take. Try the following:
- Keep the gutters and downspouts debris-free: Clearing the gutters allows melting ice to flow away from your roof into the downspouts and to the ground.
- Boost attic insulation: Get a professional to inspect and repair or replace your attic insulation if needed.
- Try to keep your roof free from snow: Stand on the ground and use a roof rake to clear your roof from excess snow and ice. Ensure the falling ice won’t impact objects on the ground, like a bed of roses, pets or people. Be careful not to dislodge or damage shingles. You should consider having a trusted professional roofing company do this, if needed.
- Get your roof inspected before winter: A roofing expert can check your roof and attic insulation while providing professional assistance with the right maintenance, insulation installation and prevention.
