The building envelope is the continuous barrier that keeps water out of a structure: the roof, the exterior walls, the windows and doors, and every joint and penetration in between. In a South Florida hurricane, water does not need a hole to get inside. It needs a tired sealant joint, a lifted section of roof membrane, a clogged scupper, or a hairline crack in a balcony deck. Pre-season, while the weather is calm and a crew can safely get on the roof and the facade, is when those weak points are cheap to find and fix.

This checklist is built for property managers and condo boards who want to walk their building, or brief a contractor, before the next storm. Deluxe Waterproofing and Caulking has inspected and sealed South Florida commercial buildings for more than 80 years as a Florida Certified General Contractor (CGC1521411), serving Miami-Dade, Broward, and Palm Beach. It is part of our commercial hurricane prep and storm recovery guide.

Roof and roof drainage

• Inspect the roof membrane for lifting, blistering, punctures, and seams that have opened.
• Check all flashing at parapets, curbs, vents, and equipment penetrations.
• Clear and test scuppers, drains, and gutters so water leaves the roof instead of ponding.
• Look for existing ponding stains, which mark low spots that will hold storm water.

Sealant and caulking joints

• Walk every expansion joint, control joint, and panel joint on the facade.
• Look for sealant that has hardened, cracked, pulled away, or gone missing.
• Check sealant around windows, doors, and any wall penetrations.
• Joints are the single most common hidden entry point for wind-driven rain.

Windows, doors, and facade

• Confirm windows and storefront systems are sealed and that weep holes are clear.
• Check door thresholds and sweeps on ground-level and stairwell doors.
• Note any cracked stucco, open masonry joints, or facade damage.

Concrete and structural surfaces

• Inspect balconies, walkways, and decks for cracking, spalling, or exposed rebar.
• Flag any surface where the coating or waterproofing has worn through.
• Anything structural should be looked at by a licensed contractor before the season.

Below grade and ground level

• Check planters, podium decks, and below-grade walls for active or past water intrusion.
• Confirm site drainage moves water away from the building, not toward it.

Small failures sealed in June are inexpensive. The same failures discovered through a leak in September mean emergency mobilization, interior damage, and a mold clock already running. If your building needs a pre-season envelope review, Deluxe serves the tri-county area and can scope the roof, joints, facade, and concrete in one visit through our waterproofing and caulking service.
