Hidden Roof Damage Found During Tear-Off

Some of the most costly roof damage is invisible until the shingles come off. During tear-off, roofing crews regularly discover conditions that were concealed beneath existing materials — damage that was not and could not be identified during the initial insurance inspection. These findings often qualify for supplement claims if properly documented.

Common discoveries during tear-off

Rotten decking

OSB or plywood sheathing that has deteriorated from prolonged moisture exposure. Rotten decking is often found along eave edges, around penetrations, and in areas where leaks went undetected. The damage is completely hidden beneath the shingle layer until tear-off exposes it. Replacement decking must be installed before new roofing materials can go down.

Flashing failure

Step flashing and counter flashing around chimneys, walls, and roof-to-wall transitions often fails over time. Corrosion, separation from mortar joints, and improper original installation are common issues. These failures create water intrusion paths that are only visible once the surrounding shingles and underlayment are removed.

Missing ice and water shield

Current building codes require ice and water shield membrane in valleys, along eaves, and around penetrations. Older roofs were often installed without it. When tear-off reveals the absence of required underlayment, the contractor must install it to bring the roof into code compliance — an additional cost that qualifies for supplemental coverage.

Code compliance issues

Beyond ice and water shield, tear-off can reveal other code deficiencies — inadequate ventilation, improper drip edge, or insufficient starter strip. When current building codes require corrections, these items can be included in a supplement request with proper documentation.

Why documenting these conditions matters

Every hidden condition discovered during tear-off is a potential supplement item — but only if the contractor documents it with clear photos, a description of the damage, and the location on the roof. Without documentation, the damage goes unreported, the supplement is never filed, and the contractor covers the cost out of pocket.

The best time to capture this evidence is the moment the damage is exposed, before the new materials go down and the evidence is covered again.
