Roof buckling is a prevalent issue that homeowners face, especially in areas with fluctuating weather conditions. It not only compromises the aesthetic appeal of your home but also poses a significant threat to its structural integrity. At Mend Roofing, we believe in empowering our clients with knowledge, so they can make informed decisions about their roofing needs.

Understanding Roof Buckling

Roof buckling manifests as ripples or waves on the roof surface, indicating that the shingles or decking might have buckled. This can be due to the roofing underlayment wrinkling or the wood deck shifting. In some cases, the buckling could be a result of poor craftsmanship, inappropriate materials, or structural issues.

Primary Causes of Roof Buckling

  • Moisture Absorption: During roof replacements, especially in the humid months, the wooden deck can absorb moisture. This can cause the deck to shift due to the increased moisture content.
  • Inadequate Ventilation: Modern homes, with their tight building tolerances and increased insulation, may lack proper ventilation. This can trap moisture in the roof system, causing the felt underlayment to absorb moisture and wrinkle.
  • Improper Installation: Buckling can arise if the tar paper is stretched and applied incorrectly. Additionally, if spacers aren’t used, the decking can experience expansion and contraction due to excessive heat.
  • Water Damage: If water seeps beneath the roof’s shingles, the decking can rot from continuous exposure, causing significant damage.
  • Roof-Over Technique: Applying new shingles directly over old, uneven ones can lead to buckling.
  • Inappropriate Nailing: Using the wrong type of nails to connect the sheathing to the rafters can result in visible bumps on the roof surface.

Effective Solutions to Address Roof Buckling

  • Repairing the Underlayment: By removing affected shingles, the wrinkled tar paper can be repaired and flattened. Subsequently, the shingles can be replaced.
  • Moisture Management: Ensure that excess moisture can exit the roofing system. Once dried, the roof should regain its flat appearance.
  • Attic Ventilation: Proper ventilation is crucial. For every 150 square feet of attic space, there should be at least 1 square foot of free vent area. Adjustments can be made based on the vapor barrier’s perm rating.

Proactive Measures to Prevent Roof Buckling

  • Choose the Right Decking Materials: Always opt for wood decking materials that are moisture-balanced with the local environment and approved by the roofing manufacturer.
  • Maintain Dryness: Ensure all decking materials remain dry before and post-installation.
  • Underlayment Selection: Use an asphalt-saturated felt shingle underlayment to cover the decking materials before shingle application.
  • Adhere to Manufacturer’s Guidelines: Always follow the manufacturer’s recommendations for ventilation and shingle installation.
