| Wind-Driven Rain & Tropical Storms | Active ceiling drip, displaced shingles, cracked mortar caps, exposed felt underlayment | Contain interior water with buckets, photograph damage from ground, call for emergency tarping | Replace blown-off shingles/tiles, inspect underlayment, seal flashings, and test roof decking | Immediate / 24-48 Hrs |
| Salt-Air Corrosion (Clearwater Beach / Sand Key) | Rusting valley metal, corroded nail shanks, deteriorated pipe boot flanges, staining on fascias | Do not scrape or walk the roof; document corrosion from ground and schedule inspection | Replace corroded flashing with coastal-rated aluminum/copper, reseal penetrations | Prompt / Same Week |
| Flashing & Penetration Failures | Staining adjacent to chimneys, skylights, plumbing stacks, or wall-to-roof step transitions | Place buckets beneath stains; do not assume a shingle patch will solve a step-flashing leak | Install new neoprene/lead pipe boots, custom bend step and counter-flashing, replace wet decking | Urgent (Rain Dependent) |
| Ponding Water on Low-Slope Roofs | Water standing >48 hours on flat Florida rooms or carports, blistering membrane seams, sag | Keep off wet membrane; clear accessible debris from scuppers or gutters without walking roof | Reseal open TPO/mod-bit seams, install tapered polyiso crickets to redirect drainage, rebuild decking | Prompt Review |
| Subtropical UV Aging & Concealed Deck Rot | Curling or brittle shingles, widespread granule loss, spongy decking underfoot, recurring leaks | Review roof installation age records; schedule full repair-versus-replacement assessment | Targeted slope section rebuild, plywood deck re-nailing to 8d ring-shank code, or full reroof | Scheduled Assessment |
