A Roofing Contractor Explains Why Your Roof Is Buckling, Clarksville, Maryland

Although they’re designed to last a lifetime, harsh weather can cause shingle roofs to buckle over time. According to the roofing contractors at Marshall’s Contracting in Clarksville, MD, buckling is often caused by high levels of moisture, improper installation, or poor quality materials. Luckily, these factors can be counteracted with proper maintenance and timely repair.

Here, this respected team of roofing contractors elaborates on the causes of buckling: 

  • Improper Installation: Before a roofing contractor installs your shingles, they have to lay down a layer of sheathing. Since it’s made from plywood, the pieces must be spaced at least half an inch apart to allow room for expansion during temperature changes. When roof sheathing doesn’t have enough room to expand, it may cause the boards to rise and the roof to buckle.
  • roofing contractorHigh Moisture Levels: Exposed wood decking absorbs excess moisture that rises from your house to your roof. Excessive moisture can cause the boards to expand, especially during periods of high humidity. To prevent this, your roofing contractor can either install a vapor barrier or an exhaust fan for improved ventilation.
  • Poor Roofing Materials: Another way to avoid buckling is to strictly use manufacturer-approved materials. You can also ask your roofing contractor to use an asphalt-saturated felt underlayment over the wood decking to prevent moisture buildup. To prevent moisture from getting trapped inside, shingle roofs should not be exposed to high levels of moisture, rain, or water during and a few days after installation.
