• Faulty flashing. It is a sheet of metal utilized in waterproofing roofing valleys, dips and angles. Try to find flashing rust or dislocation, which is common in Ohio and places nearby.
  • Blocked downspouts or crevasses. Downspouts may be choked with accumulated water or snow right above the flashing which might have caused the leakage. This would be a basic roof leakage repair.
  • Cracking and deterioration. Roofing generally degrades due to wear and tear. Check for any cracking.
  • Holes. Missing out on shingles or holes will trigger wet spots. Depending upon the Ohio environment, these can become severe quickly.
