my new roof looks wavy

A new roof installation is a significant investment in your home. It not only provides protection from the elements but also contributes to the aesthetic appeal of your property. Ideally, a new roof should be flat and smooth, reflecting the high standard of workmanship. However, there might be times when you notice some irregularities, like waviness or buckling. This article will explore why a new roof might look wavy, the potential structural implications, and the solutions to rectify these issues.


Reasons for Waviness in a New Roof


1. Improper Installation: A common cause of waviness is incorrect installation. If the roofing contractor does not properly align and fasten the shingles, it can lead to an uneven appearance. Similarly, inadequate nailing or the use of too few nails can also result in a wavy roof.


2. Underlayment Issues: The underlayment is an essential component of a roofing system, providing an extra layer of protection against water and wind damage. If the underlayment is wrinkled or incorrectly installed, it can cause the shingles to appear wavy.


3. Decking Problems: The decking is the foundation on which the roof rests. If the decking has any imperfections, such as warping or unevenness, it will likely cause a wavy appearance in the overlying shingles.


4. Thermal Buckling: Shingles can buckle and become wavy due to dramatic temperature changes. This is more common with asphalt shingles, which expand in hot weather and contract in cold weather, causing them to distort over time.


Implications of a Wavy Roof


While a wavy roof may not necessarily indicate a structural problem, it's not something to ignore. If the waviness is due to improper installation or substandard materials, your roof may fail sooner than expected, leading to potential water damage, mold growth, and other serious structural issues. A wavy roof can also impact your home's curb appeal and resale value.


Solutions for a Wavy Roof


1. Professional Roof Inspection: If you notice that your new roof is wavy, the first step is to contact a professional roofer for an inspection. They can help identify the cause of the problem and suggest the best course of action.


2. Repair or Replacement: Depending on the cause and extent of the waviness, your roofer may recommend repairs or a full roof replacement. If the problem is due to improper installation, it might be necessary to replace the affected shingles or entire sections of the roof.


3. Legal Action: If your roof was installed incorrectly, causing it to be wavy, you might be able to seek recourse from the installation company or contractor. It's advisable to consult with a lawyer to understand your rights and potential remedies.


4. Regular Maintenance: Regular roof maintenance can help prevent issues like waviness in the future. This includes routine inspections, timely repairs, and ensuring that your attic is well-ventilated to prevent excessive heat buildup.


Conclusion


A wavy new roof can be disconcerting, but understanding the potential causes can help you take the necessary steps to address the issue. With professional help, you can ensure that your roof not only looks good but is also structurally sound, providing the necessary protection for your home for many years to come.
