Roof Construction Defects

The roof is constructed with many elements, including framing, plywood decking, felt underlayment, sheet metal flashings and the exterior roof itself.  The exterior coverings of the roof can be finished with asphalt shingles, clay tile, aluminum, or wood shake, among others.  Water intrusion through the roof from a construction defect can lead to property damage inside the house.  Damage may include framing, ceilings, drywall, paint and wallpaper.  Mold is also a definite concern from water intrusion as it could result in unhealthy indoor air quality. 

Listed here are some of the construction defect concerns related to the roof:

  • Valley metal cut too short
  • Split, torn or deteriorated felt
  • Open gaps at joints of flashing
  • Missing anti-ponding metal at eaves
  • Broken and chipped roof tiles
  • Roof tiles overexposed, improperly lapped and misaligned
  • Roof paper or “felt” fails to completely cover roof deck
  • Failure to use corrosion-resistant nails
  • Flashing improperly installed at chimney saddles and skylight
  • Roof tiles not attached, loose and sliding
