Why Do Shingles Curl in Winter?

When winter arrives, homeowners may notice an unexpected problem with their roofs—curling shingles. This phenomenon can lead to costly repairs if not addressed properly. Understanding why shingles curl in winter and how to prevent it can save you from potential damage and prolong the life of your roof.

In this guide, we’ll explore the common reasons shingles curl during the colder months and how you can protect your home from this issue.

What Causes Shingles to Curl in Winter?

Shingle curling occurs when the edges of the shingles lift or bend upwards, compromising the protective barrier of your roof. Several factors contribute to this problem:

1. Poor Attic Ventilation

• Inadequate attic ventilation can cause heat buildup under the shingles, leading to expansion and curling as they cool down unevenly.

2. Moisture Build-Up

• Trapped moisture in the attic can lead to condensation, which weakens the roofing materials and causes them to curl.

3. Aging and Wear

• Over time, shingles naturally deteriorate, and cold weather can accelerate this aging process, making curling more noticeable.

4. Improper Installation

• If shingles are not nailed down properly or are placed incorrectly, they may be more prone to curling under extreme weather conditions.

5. Low-Quality Materials

• Cheap or low-quality shingles are more susceptible to temperature fluctuations, which can lead to curling and cracking.

6. Ice Dams

• Ice dams form when snow melts and refreezes at the edges of the roof, causing water to back up under the shingles and leading to curling and damage.

How to Prevent Shingles from Curling in Winter

To avoid costly roof repairs, homeowners should take preventative measures to protect their shingles from curling.

1. Improve Attic Ventilation

• Proper airflow helps regulate temperature and moisture levels, reducing the risk of shingle curling.

2. Regular Roof Inspections

• Schedule inspections with a trusted roofing contractor like S&K Construction and Remodeling LLC to identify potential issues early.

3. Use High-Quality Shingles

• Investing in durable, weather-resistant shingles helps prevent premature wear and curling.

4. Keep Gutters Clean

• Clogged gutters can cause water backup, increasing the likelihood of ice dams and shingle curling.

5. Address Moisture Issues

• Ensure proper insulation and vapor barriers in your attic to prevent moisture buildup.

What to Do If Your Shingles Are Curling

If you notice curling shingles, it’s crucial to take action before the problem worsens.

1. Inspect the Damage

• Assess whether the curling is widespread or limited to a few areas.

2. Schedule Professional Repairs

• Contact a licensed roofing contractor to evaluate whether repairs or a full replacement are necessary.

3. Consider a Roof Replacement

• If curling is extensive, a new roof may be the best long-term solution.

4. Apply Roof Sealant

• In some cases, a roofing sealant can help secure curling shingles temporarily until a permanent solution is implemented.
