Synthetic shake roofing is designed to mimic the look of natural wood shakes but made from durable materials like polymer or rubber. However, one common concern with synthetic shake is wind uplift, which occurs when strong winds create suction that can lift and loosen the shingles. This problem typically happens if the shingles are not properly nailed down or if the roof lacks adequate ventilation or underlayment, allowing air pressure to build under the shingles. Over time, poorly fastened shingles can curl or even blow off, exposing your roof to water damage and other issues. To check for early signs, homeowners can safely inspect their roof from the ground or a ladder, looking for loose or missing shingles and any gaps between them. Listening for a flapping sound during windy days can also indicate weak attachment points.
If you notice any lifted shingles or spaces where wind could get underneath, it’s usually time to call a professional roofer. A qualified contractor can assess the fastening method used—coating nails or clips must meet wind-resistance standards outlined in your product warranty and local building codes. During your consultation, ask if they will perform a wind-load test and confirm that they use approved fasteners to ensure the roof withstands strong winds. You might also inquire about the type of underlayment and ventilation system they recommend, as these help reduce pressure changes under the shingles. Fixes can range from re-securing loose shakes with proper nails or clips to completely replacing the synthetic shakes with a wind-rated product. Ensuring installation matches manufacturer guidelines is key to protecting your roof and maintaining your warranty.
