A Warning Sign: Lifting Shingles on Your Roof's Edge
Notice something like this on your home? This image shows moderate severity damage that could lead to serious leaks.
What you’re seeing:
An asphalt shingle is lifted or curled up at the eave (the edge of the roof).
The shingle tab is lifting away from the roof deck, a critical problem in the "starter course" where the roof should be most secure.
You can clearly see the underlying layer and the white-painted fascia board below.
Likely Causes for This Type of Damage:
Improper installation: The starter shingle may not have been correctly secured.
Missing or inadequate fasteners: Not enough nails were used, or they were placed incorrectly.
Wind damage: Strong gusts can easily lift the edges of shingles that are already a bit loose.
Age-related adhesive failure: Over time, the sealant strip on the shingle stops working.
Thermal cycling: The repeated heat of the sun followed by cooling can cause materials to expand and contract, breaking their seal.
Why It's a Problem:
The biggest risk here is water infiltration. This lifted edge allows rain and melting snow to blow directly beneath the shingles. From there, it can rot your roof deck and leak into your attic, ceiling, or walls.
The Solution:
This requires prompt repair or replacement of the affected shingles by a roofing professional to prevent water damage to your home.
