It is not necessary to be at home during the re-roofing process, but it is a good idea to be available by phone as unexpected things come up that your Pyramid Representative may need to consult with you about. It is typical to run into unforeseen roof repairs, but good communication between the Pyramid Representative and the homeowner is invaluable to the successful outcome of the project. For example: When the existing roofing materials are removed, repairs that were not visible and therefore not contracted for, are necessary (replacement of sheathing or other structural issues due to dry rot or water damage). This is what is normally referred to as a “change order”.
