Winter weather can be tough on your roof. The combination of snow, ice, freezing temperatures, and heavy winds can all contribute to roof leaks. Even if your roof has been well-maintained, the harsh elements of winter can still cause unexpected problems. The good news is that many roof leaks are preventable, and spotting them early can save you from costly repairs down the line.
In this blog post, Pinnacle Roofing walks you through how to spot roof leaks caused by winter weather and what steps to take to repair them, ensuring your home stays dry and warm all season long.
How Winter Weather Causes Roof Leaks
Before diving into how to spot and repair leaks, it’s important to understand how winter weather can damage your roof. The following winter conditions are common culprits:
- Snow Accumulation: Heavy snow can accumulate on your roof, creating a heavy load that can stress your roof structure. When snow melts, it may seep under shingles, causing leaks.
- Ice Dams: Ice dams form when warm air in your attic melts the snow on your roof, which then refreezes at the eaves. This ice buildup can prevent water from draining off the roof and cause it to back up under the shingles, leading to leaks.
- Freezing and Thawing: The freeze-thaw cycle is especially problematic during winter. Water that gets under your shingles or into small cracks can freeze overnight, causing the materials to expand and contract, which can loosen shingles or create cracks.
- Wind and Storm Damage: Winter winds can lift shingles or create gaps where moisture can seep through. Ice or snow buildup may also cause shingles to crack or break off.
Now, let’s look at how you can spot these leaks and take action to prevent further damage.
How to Spot Roof Leaks Caused by Winter Weather
1. Inspect Your Attic for Signs of Moisture
One of the best ways to spot a roof leak is by checking your attic. Leaks often first show up here, as the water can seep through the roof and trickle down into the attic insulation.
- Look for Water Stains: Water stains on the ceiling or walls of your attic can indicate a leak. These stains often appear as yellow or brown patches and may signal a spot where ice dams or snowmelt have infiltrated your roof.
- Check for Mold or Mildew: Mold and mildew thrive in moist environments. If you notice a musty smell or see mold growth in the attic, this is a sign that your roof might be leaking.
- Examine Insulation: Wet insulation in your attic means there’s likely a leak in your roof. Wet insulation will not only compromise the insulation’s ability to keep your home warm, but it can also lead to mold growth.
2. Look for Icicles or Ice Dams on the Roof
Ice dams can be a major source of leaks. If you see large icicles hanging from your gutters or a buildup of ice along the eaves of your roof, this is a sign that you could have an ice dam. Ice dams trap water, which can then leak under shingles and cause water damage to your home’s interior.
- Check for Water Drips Inside: If you notice water dripping from the ceiling, especially after a snowstorm or period of melting snow, it could be caused by an ice dam.
- Inspect the Gutters: Ice buildup in the gutters, along with snow on the roof, can cause water to backup. Check your gutters for signs of icicles or ice blockages that may be contributing to leaks.
3. Check for Missing or Damaged Shingles
Winter winds and snow can damage shingles, especially if they are older or brittle. Missing or cracked shingles expose the underlying roof structure to water infiltration.
- Look for Loose or Lifted Shingles: Strong winds can lift shingles, making them vulnerable to water infiltration. Check your roof for any signs of shingles that look like they are no longer properly secured.
- Look for Cracked Shingles: Freezing and thawing cycles can cause shingles to crack. Cracked shingles are much more likely to let water through.
- Inspect Flashing: Flashing around chimneys, vents, skylights, and other roof penetrations can become compromised in winter. Snow and ice buildup can loosen or damage flashing, leading to leaks.
How to Repair Roof Leaks Caused by Winter Weather
1. Patch Small Leaks Immediately
If you spot a small leak, you can temporarily patch it until you can get professional help. Use roofing tape or roofing sealant to cover small cracks or holes. This won’t fix the underlying issue, but it can stop the water from leaking further into your home.
Important Note: Temporary patches are a short-term solution. Roof repairs should be performed by a professional as soon as possible to avoid long-term damage.
2. Clear Snow and Ice from the Roof
If you have heavy snow or ice on your roof, it’s essential to remove it to prevent further damage. Use a roof rake with a long extension to gently remove snow from the edge of the roof. Be careful not to damage the shingles, and never climb onto the roof in icy conditions. If the snow buildup is severe, consider calling a professional to safely remove it.
If you see ice dams forming along the edges of the roof, you may need to carefully break them up using a hammer and chisel. Alternatively, you can use a roof de-icing product designed to melt the ice safely. If you’re unsure, reach out to a roofing contractor for help.
3. Address Ice Dams with Proper Insulation and Ventilation
Once you’ve removed the ice, consider adding additional insulation and ventilation to your attic. Proper ventilation helps keep your attic cool, preventing the snow from melting too quickly. Adequate insulation ensures that warm air doesn’t escape from your living spaces, which is one of the primary causes of ice dams.
Pro Tip: Installing ridge vents and soffit vents can improve airflow in your attic and help prevent the buildup of heat that causes ice dams.
