Older decking, reroofs and layers
Older roofs can have decking that is thinner or less well fastened than current practice, and a past reroof may have been placed over earlier layers. Moisture trapped between layers speeds rot, and heat bakes the shingles from both sides. When a roof is opened, soft spots in the wood are not unusual.
Margate sits between Florida's Turnpike and State Road 7, and it feels the same sun, humidity and afternoon storms as the rest of South Florida. Granules wash into gutters, shingles curl and cracks open around vent boots long before the roof leaks. A bucket under a stain in the ceiling is often the last stage, not the first.
