Fiberglass shingles are a popular choice for roofing thanks to their durability and affordability, but they can be vulnerable to wind uplift, which happens when strong winds get underneath the edges or corners of the shingles and lift them off the roof. This problem often arises when shingles weren’t nailed down properly, the adhesive strips didn’t seal due to cooler or damp conditions during installation, or the shingles themselves have aged and lost some of their grip. Wind uplift can lead to curled or loose shingles and eventually cause leaks or more serious roof damage. A simple way to diagnose this at home is by looking for shingles that appear to be lifting or flapping during windy conditions, or checking after a storm for missing or damaged shingles. Make sure to access your roof safely using a sturdy ladder and avoid stepping directly on damaged shingles.
For DIY checks, safely inspect the roof edges and valleys for signs of raised shingle tabs or broken sealant strips without climbing onto a high or steep roof if you’re uncomfortable. It’s also wise to monitor the attic after storms for signs of leaks or drafts. If you notice frequent shingles lifting or shingles missing after moderate winds, it’s time to call a professional roofer who can assess the fastening quality and shingle integrity. When consulting a contractor, ask “Can you confirm if the shingles meet local wind rating requirements and whether the roofing nails were installed at the proper depth and locations?” and “How do you ensure the adhesive seal strips activate properly during installation, especially in cooler weather?” Keeping your roof warranty in mind, always get a written report and confirm that any repairs won’t void coverage.
