Job length can vary from 1 day to several weeks. This depends on the complexity of the roof (or any other trade being completed), availability of material, weather, and other unforeseen extenuating circumstances that may arise. If the weather conditions get severe and safety becomes a factor, all work will halt until any and all risks to the crews has passed. If this would occur, we always carry tarps for unexpected emergencies to make sure your roof is sealed tight. Weather can create a slower process and may affect scheduling, so allow for possible delays in the completion of your project. Remember, re-roofing your home is major construction, but a reputable Pyramid Representative will take necessary precautions to keep your home and family safe and dry.
