The answer to 'why is my drip edge' is that the drip edge on your roof may be damaged, loose, or improperly installed. The drip edge is a critical component that helps direct water away from the roof's edge and prevent leaks and damage to the fascia and siding. Common issues include nails working loose, the drip edge pulling away from the roof, or gaps and cracks allowing water infiltration.
To fix a problem with your drip edge, you may need to re-secure the drip edge with new nails or screws, seal any gaps with a high-quality sealant, or in some cases replace the entire drip edge if it is severely damaged. While some minor drip edge repairs can be a DIY project, it's generally best to have a professional roofing contractor inspect and fix any issues to ensure it is properly installed and sealed to prevent future leaks.
