5 Things That Void Your Roof Warranty

5 Things That Void Your Roof Warranty

Your roof is one of the most significant investments you’ll make in your home, and its warranty provides peace of mind that your roofing materials and installation are covered for a certain period. However, many homeowners don’t realize that certain actions—or inactions—can void their roof warranty, leaving them unprotected if problems arise. Understanding what can void your roof warranty is essential to ensuring you get the full benefits of the coverage.

In this guide, we’ll discuss five common things that can void your roof warranty and how you can avoid making costly mistakes.

1. Improper Installation

One of the most common reasons for a voided roof warranty is improper installation. Roofing manufacturers have specific guidelines for how their products must be installed to ensure durability and performance. If your roofing contractor doesn’t follow these guidelines, the manufacturer may refuse to honor the warranty.

How to Avoid This Issue:

• Always hire a professional, licensed, and certified roofing contractor.
• Choose a contractor who is certified by the manufacturer of your roofing materials.
• Ask for proof that the contractor has followed the manufacturer’s installation guidelines.
• Request a final inspection after installation to ensure compliance.

2. Poor Ventilation and Improper Maintenance

Roofing warranties often require that your attic has proper ventilation to prevent heat and moisture buildup. Poor ventilation can cause shingles to age prematurely, leading to warping, curling, or cracking. Additionally, neglecting roof maintenance can lead to issues that might not be covered under the warranty.

How to Avoid This Issue:

• Ensure your attic has proper ventilation with intake and exhaust vents.
• Regularly inspect your roof for signs of damage, such as missing shingles or clogged gutters.
• Schedule annual roof inspections with a professional to catch potential problems early.
• Remove debris, moss, and algae growth that could cause premature deterioration.

3. Installing a Second Layer of Shingles

Some homeowners opt for a nail-over reroof, where new shingles are installed over an existing layer to save money. However, most manufacturers do not support this practice, as it can lead to improper adhesion, excess weight, and hidden damage beneath the old shingles.

How to Avoid This Issue:

• If your roof needs replacing, have the old shingles removed completely before installing a new roof.
• Consult with a professional roofer to determine the best approach for your roof replacement.
• Check with your manufacturer to confirm their warranty terms regarding reroofing.

4. Unauthorized Roof Modifications or Installations

Making modifications to your roof, such as installing satellite dishes, solar panels, or skylights, can void your warranty if not done correctly. Puncturing or altering roofing materials without following manufacturer guidelines can lead to leaks, structural issues, and premature wear.

How to Avoid This Issue:

• Work with professionals who specialize in installing rooftop additions while preserving the integrity of the roofing system.
• Check your warranty details before making any roof modifications.
• Use manufacturer-approved fasteners and sealing techniques to prevent leaks and damage.

5. Using Non-Manufacturer Approved Materials

Your roof warranty typically covers specific materials that have been tested and approved by the manufacturer. If you or your contractor use non-approved materials—such as underlayment, flashing, or adhesives—it can lead to performance issues and a voided warranty.

How to Avoid This Issue:

• Always use manufacturer-approved materials for any repairs or replacements.
• Verify that your contractor is using the right products as specified in your warranty.
• Keep records of materials used in case you need to file a warranty claim in the future.

Final Thoughts

Your roof warranty is a valuable asset that protects your investment, but it’s crucial to understand the factors that can void it. Improper installation, poor maintenance, second-layer shingling, unauthorized modifications, and using non-approved materials are among the most common reasons warranties become void. By working with certified professionals, following manufacturer guidelines, and keeping up with regular maintenance, you can ensure your warranty remains valid and your roof lasts for years to come.

If you’re planning a new roof installation or need maintenance, be sure to choose a reputable roofing contractor who understands warranty requirements. Protect your home, your investment, and your peace of mind by following the right steps to keep your roof warranty intact.
