Yes, rotted roof decking can be considered a structural emergency because moisture can rapidly spread from the sheathing to the joists and interior framing.
In the wet climate of Metro Vancouver, what begins as localized decay can quickly escalate into a serious structural issue that compromises the entire roofing system. Left unaddressed, this decay leads to safety hazards, risks of structural failure, and escalating repair costs.
Key indicators that the rot has reached a critical stage include:
- Visible sagging: A noticeable dip or sag in the roofline or attic rafters.
- Spongy surface: A “springy” or soft feel when walking on the roof surface, indicating the wood has lost its integrity.
- Internal damage: Significant ceiling water stains, peeling paint, or crumbling wood in the attic space.
- Visible gaps: In severe cases, daylight may be visible through gaps in the decking boards when viewed from the attic.
Because decaying sheathing threatens the foundation that supports your shingles and interior structure, immediate professional evaluation is required to determine if the damage necessitates a full structural replacement.
