I’m perplexed by someone who would tell this Owner that the roofing contractor would automatically repairs any “damages” incurred due to the leaking roof and I couldn’t disagree more. I would add that integrity has nothing to do with repairing interior damage caused by leaks; it’s simply a matter of responsibility under the warranty.
First, a typical roof warranty would be for materials, workmanship, etc. and would be a guarantee against leaks and their repair during the warranty period. In no way does the warranty stipulate that it would cover interior damage, for the simple reason that no mfg. (or contractor for that matter) would take on that type of liability. Can you imagine the insurance claim for roof leaks at a Food Processing Plant with multimillion dollar equipment, which is claiming damage from roof leaks 5, 6, 7 ….years after the roof was installed? There would be no end to lawsuits and insurance claims, which is the obvious reason interior damage is not covered.
Additionally, there are too many unknown factors to determine if the materials and workmanship were actually the cause of the leak, which could have resulted from roof top traffic (especially on commercial properties), high winds, etc.
I would add that a roofing contractors insurance wouldn’t be responsible for post roof installation damage, however, this would be a different matter if the building or home received damage DURING the roofing installation. The two are completely different matters.
