One of the most frustrating issues homeowners can face after installing a new roof is new roof shingles buckling. This problem not only affects the aesthetic appeal of your roof but can also lead to long-term structural damage if not addressed promptly. Understanding the causes, preventative measures, and solutions to buckling shingles can save you time, money, and further headaches down the road.
In this article, we’ll dive into everything you need to know about new roof shingles buckling. This guide covers the causes, prevention, and fixes for buckling to help you keep your roof in top condition.
What is New Roof Shingles Buckling?
Buckling shingles refer to roof shingles that appear to warp, lift, or wrinkle, giving the roof a wavy appearance. This problem can occur shortly after a new roof is installed or even after a few years, depending on various factors. Buckling typically occurs when shingles are not lying flat against the roofing structure, causing gaps, folds, or raised areas.
Buckling roof shingles often signal poor installation or structural issues but can also indicate moisture buildup or poor ventilation. Ignoring it may lead to water leaks, roof damage, and a shorter lifespan for your roofing materials.

Common Causes of New Roof Shingles Buckling
There are several reasons why new roof shingles buckling occurs. By understanding the root causes, homeowners can take steps to prevent this problem from happening or address it if it arises.
1. Improper Installation of Shingles
The most common cause of buckling shingles is improper installation. If the shingles were not laid down correctly or the nails were improperly placed, the shingles could begin to lift and buckle soon after installation. For example, if shingles are nailed too tightly or not secured flat, they may start to warp as they expand or contract due to temperature changes.
Additionally, shingles need time to “settle” into place after installation. If this process is rushed, or if shingles are installed in wet conditions, they may not adhere properly, leading to buckling.
2. Moisture in the Roof Deck
Moisture trapped in the roof deck can cause shingles to buckle. This can happen if the roof was installed before the roof deck (the wooden layer under the shingles) was fully dry, or if moisture enters the roof deck due to leaks, poor insulation, or insufficient ventilation.
Over time, as the wood in the roof deck absorbs and releases moisture, it can expand and contract, causing the shingles on top to shift and buckle. This is especially common in climates with high humidity or frequent rainfall.
3. Inadequate Roof Ventilation
Proper roof ventilation is critical for preventing new roof shingles buckling. Without adequate ventilation, heat and moisture can build up in the attic or under the roof deck, causing the shingles to warp or buckle. High temperatures in an attic without ventilation can also cause shingles to expand and shift, especially in hot climates.
A well-ventilated roof allows air to flow through, helping to regulate temperature and prevent moisture buildup. This is key to maintaining the structural integrity of both the roof deck and shingles.
4. Underlayment Issues
Roof underlayment is a protective layer installed between the roof deck and the shingles. It helps to provide an extra barrier against moisture and weather elements. However, if the underlayment is not installed correctly or becomes wrinkled due to moisture or poor installation, it can cause the shingles to buckle. The underlayment should be laid flat and properly secured to prevent any shifting or bulging that could affect the shingles above it.
5. New Wood Decking Movement
When a new roof is installed, especially on new or recently replaced wood decking, the wood may continue to settle, shrink, or expand as it adjusts to environmental conditions. If the roof decking moves, the shingles attached to it may buckle. This is more common when green or untreated wood is used for the decking, as it absorbs and releases moisture more easily.
How to Prevent New Roof Shingles Buckling
Preventing new roof shingles buckling begins with proper installation techniques, choosing the right materials, and ensuring proper ventilation and moisture control. Here are the best practices for preventing buckling shingles:
1. Hire a Professional Roofing Contractor
Ensuring that your roof is installed by a qualified and experienced roofing contractor is one of the best ways to prevent buckling shingles. A professional roofer will know how to properly install shingles, secure them with the right type of nails, and make sure the underlayment is laid flat. A reputable roofer will also understand the importance of ventilation and moisture control to prevent future problems.
2. Ensure Proper Roof Ventilation
Proper roof ventilation is essential to prevent heat and moisture buildup that can warp and buckle shingles. Ensure your attic has intake vents at the bottom and exhaust vents at the top for adequate air circulation. This can help regulate temperature and prevent moisture from accumulating in the attic or under the shingles.
3. Allow Roof Decking to Dry
Before installing a new roof, it’s essential to allow the roof decking to fully dry if it has been exposed to moisture. Installing shingles over a damp roof deck can lead to buckling as the wood expands and contracts over time. Make sure that the decking is dry, and consider installing a moisture barrier or underlayment that provides additional protection against water infiltration.
4. Choose the Right Materials
Using high-quality roofing materials can also help prevent new roof shingles buckling. For example, opt for shingles that are designed to withstand the specific climate conditions in your area. Some shingles are more resistant to heat and moisture than others, making them a better choice for preventing buckling in humid or hot regions.
5. Monitor Roof Conditions Regularly
Even after your new roof is installed, regular maintenance and inspections are key to preventing issues like buckling. Monitoring your roof for warping, water damage, or ventilation issues allows you to address problems early. Regularly clearing debris, inspecting shingles and underlayment, and ensuring proper ventilation will keep your roof in top condition.
How to Fix New Roof Shingles Buckling
If you’ve noticed new roof shingles buckling, it’s important to address the problem as soon as possible to prevent further damage. Here are the steps you can take to fix buckling shingles:
1. Identify the Cause
The first step in fixing buckling shingles is to identify the root cause of the problem. Was the roof improperly installed? Is there moisture trapped in the roof deck? Is there insufficient ventilation? Understanding the underlying cause will help you determine the best course of action.
2. Fix the Ventilation
If poor ventilation is causing the shingles to buckle, adding more vents to the roof can help fix the issue. By improving airflow in the attic or under the roof deck, you can reduce heat and moisture buildup, preventing further warping.
3. Remove and Replace Affected Shingles
In some cases, the only way to fix buckling shingles is to remove and replace the affected sections. This is especially important if the shingles are warped due to improper installation or if they are damaged beyond repair. Work with a professional roofer to remove the damaged shingles and install new ones correctly.
4. Repair the Underlayment
If the underlayment is the source of the buckling, it may need to be replaced or re-secured. A wrinkled or loose underlayment can cause shingles to warp, making it essential to fix this issue. Ensure that the new underlayment is laid flat and properly attached to prevent future movement.
5. Monitor and Maintain the Roof
After fixing the buckling shingles, be sure to monitor the roof for any future signs of warping or damage. Regular maintenance, including clearing debris and checking for moisture or ventilation issues, will help prevent new problems from arising.
Conclusion
New roof shingles buckling can be a frustrating and costly issue, but with proper installation, regular maintenance, and addressing any underlying problems such as ventilation or moisture buildup, you can keep your roof in excellent condition. Whether you’re installing a new roof or maintaining an existing one, understanding the causes and solutions for buckling shingles will help you protect your home and extend the lifespan of your roof.
By working with a professional roofer, ensuring proper ventilation, and monitoring your roof for signs of damage, you can prevent shingles from buckling and ensure your roof remains durable and beautiful for many years.
