Why Is My Roof Drip Edge Allowing Water Into the Fascia?

The drip edge is a metal flashing installed along the eaves of your roof. Its job is to guide rainwater away from the fascia board and into the gutter. When it sits flush against the roof deck and extends past the fascia, water drips off cleanly.

If the drip edge is lifted, bent, or nailed too high, water can run behind it. That lets moisture reach the fascia and the wood underneath. In Detroit's humid continental climate, that trapped water can lead to rot and mold over time.

• Check if the drip edge overhangs the fascia by at least 2 inches
• Look for gaps or lifting along the edge
• Ensure the drip edge is not nailed through the top flange
• See if ice dams in winter push water up under the flashing

In cold winters, ice dams can form at the eaves. They block melting snow from draining, forcing water up under the shingles and behind the drip edge. Once water gets behind the flashing, it can soak the fascia and the roof deck.

If you see icicles hanging from the fascia or water stains on the ceiling below, ice is likely the culprit. Removing snow from the roof edge with a roof rake can help, but the underlying flashing may still need adjustment.

• Use a roof rake after heavy snowfalls
• Ensure attic insulation and ventilation are adequate to prevent ice dams
• Consider installing a water-repellent membrane under the shingles
• Clear gutters before winter to allow proper drainage

If you cannot see the problem from the ground, or if the fascia shows signs of rot, it's time to have a professional look. The pros can safely access the roof and inspect the drip edge, flashing, and underlying wood. They can also check for hidden water damage in the attic.

For a comprehensive evaluation, consider both a roof leak repair and a water damage inspection. That way, you address the source and any existing damage. Acting quickly can prevent a small leak from becoming a major structural issue.
