This is typically due to improper installation or the guards trapping moisture and heat under the shingles. Symptoms include visible curling or buckling of the shingles, which can lead to leaks and other roofing problems.
The best solution is to have a professional roofing contractor inspect the installation and make any necessary adjustments or repairs. They can ensure the gutter guards are properly fitted and ventilated to prevent shingle damage. In some cases, it may be necessary to remove the gutter guards altogether if they are causing persistent issues. DIY homeowners should exercise caution when working on the roof and consider calling in a pro for complex gutter guard projects.
