When a commercial roof is showing its age but the structure beneath is still sound, a recover might be the smarter move than a full tear-off. Instead of stripping everything down to the deck, we lay new insulation and membrane right over the existing roof. It's quicker, creates less waste, and often costs less, but you've got to make sure the old roof is dry and structurally fit to handle the extra weight.
