What are the biggest red flags in a roof inspection?

The biggest red flags in a roof inspection typically involve structural issues, water damage, or signs of aging that could lead to serious problems if left unaddressed.

Critical Red Flags to Watch For

Missing or Damaged Shingles: Large areas of missing, cracked, or curling shingles indicate the roof is nearing the end of its lifespan or has sustained storm damage. This compromises your home’s protection against water infiltration.

Sagging or Structural Issues: Any sagging in the roof deck or rafters suggests serious structural problems that require immediate attention. This could indicate water damage to the underlying wood structure or inadequate support.

Water Stains and Leaks: Interior water stains on ceilings or walls, or active leaks in the attic, are major concerns. Even small leaks can cause significant damage over time, including mold growth and wood rot.

Deteriorated Flashing: Flashing around chimneys, vents, and skylights is crucial for preventing leaks. Rusted, cracked, or improperly installed flashing is a common source of water intrusion.

Additional Warning Signs

Granule Loss: Excessive granules in your gutters or bare spots on shingles indicate advanced wear. Asphalt shingles rely on these granules for UV protection.

Moss and Algae Growth: While not always urgent, heavy moss growth can trap moisture and accelerate shingle deterioration, particularly on north-facing slopes.

Poor Ventilation: Inadequate attic ventilation can cause premature roof failure due to heat and moisture buildup, warping shingles from the inside out.

If your inspector identifies any of these issues, get multiple quotes for repairs and don’t delay addressing serious problems. Some issues may be covered by homeowners insurance if caused by storm damage.
