I second the comment about finding another insurance company/policy. Before we started to spend winters in the south I contacted our broker who confirmed that the coverage would continue as long as we had the house checked.
Two winters ago we had an ice storm and a tree branch broke and fell on the roof, a neighbour E-mailed us to report it. I E-mailed the broker who sent out a crew to inspect the roof, they had to put rock salt on the ice to check for roof damage, turned out that the only damage was to the eaves trough, and the cost estimate was lower than our deductible so I waited until our return to get it fixed. No charges from the insurance company and all done via E-mail.
