Roof

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 this 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
