| Roofing warranties typically do not warrant that the roofing system is appropriate for the building in question; nor do they warrant that the roof will not leak. The best warranties normally cover repairing leaks that may occur, and normally exclude leaks caused by: natural disasters, acts of God, structural movement, failure of components involved with, but not part of, the manufacturers’ system, alterations made to the roof or effecting the roof, substrate failure, change in building’s use, roof traffic, lack of roof maintenance by the building owner, roof ponding, environmental or chemical fallout, any repairs made not using the manufacturers’ products, fire, abnormal weather conditions, falling objects, other trade damages, vegetation or insect damage, etc. |
