A Florida home’s exterior takes more abuse than homes in most other parts of the country. The combination of intense UV radiation, salt air (within 10 miles of the coast), temperature swings, hurricane-force winds, and torrential rain accelerates wear on every exterior surface.
A $200 annual maintenance routine prevents a $20,000 repair bill. Here’s exactly what to do, month by month.
Why Florida Exteriors Age Faster
Before the schedule, it helps to understand why:
- UV radiation: Florida receives the second-highest UV index in the country. Exterior paint, caulk, and roofing materials degrade 40–50% faster than in northern states.
- Salt air: Coastal and near-coastal homes (within 5–7 miles of the ocean or Gulf) have salt deposits landing on every surface. Salt is corrosive to metal fasteners, screen frames, and paint adhesion.
- Thermal expansion cycles: Florida’s 90°F+ summer temperatures cause dramatic expansion and contraction in roofing, stucco, and concrete. This is why caulk and sealants crack faster here.
- Biological growth: Algae, mold, mildew, and lichen grow year-round on roofs, driveways, and painted surfaces in Florida’s humidity. Black streaks on your roof are algae (Gloeocapsa magma), not dirt.
The Annual Exterior Maintenance Schedule
January–February: Post-Season Assessment
After hurricane season ends, do a full exterior walkthrough:
- Inspect roof for cracked, loose, or missing shingles and damaged flashing around vents, pipes, and the chimney (if applicable)
- Check all caulking around windows and doors — caulk that is cracked, pulling away, or missing exposes your wall cavity to water intrusion
- Inspect screen enclosures and pool cages for torn screens and bent frames — repair before love bug season (April–May)
- Clean and treat any rust on wrought iron, metal railings, or fence posts
March–April: Soft Washing Season
This is the best time to clean exterior surfaces before the summer rainy season:
- Roof: Hire a licensed soft wash company (not a pressure washer — high pressure damages shingles) to treat black algae streaks. Use a sodium hypochlorite solution. A clean roof reflects more heat and lasts longer.
- Driveway and walkways: Pressure wash concrete to remove algae, mold, and tire marks. Re-seal if it’s been more than 2 years.
- Stucco and siding: Soft wash with a low-pressure garden sprayer and a diluted bleach solution to kill mold and mildew. Rinse thoroughly.
- Gutters: Clean out all debris from winter. Check that gutters slope properly toward downspouts (you should see no standing water after a rain).
May: Pre-Season Prep
The window between spring cleaning and the start of hurricane season (June 1):
- Touch up exterior paint on trim, fascia, and any peeling areas — if more than 25% of a surface is peeling, budget for a full repaint
- Seal any new cracks in stucco with elastomeric caulk (not standard caulk — Florida’s thermal expansion requires a product that can flex)
- Test and clean gutters one more time — they need to be clear before the daily afternoon thunderstorms start
June–November: Hurricane Season Vigilance
- Inspect the roof after any significant storm — even a near-miss can loosen shingles
- Clear gutters after heavy leaf fall
- Check foundation and driveway for new cracks after any earth movement events
December: Year-End Check
- Inspect all weather stripping on doors and windows
- Re-caulk where needed
- Flush and test outdoor faucets and irrigation systems
The Two Biggest Exterior Mistakes Florida Homeowners Make
1. Ignoring roof algae. Black streaks on your roof are not cosmetic — algae degrades roofing materials by feeding on the limestone filler in asphalt shingles. A roof that isn’t cleaned regularly will need replacement years sooner.
2. Using the wrong paint. Florida requires 100% acrylic exterior paint with mold and mildew inhibitors. Latex paint, oil-based paint, and even many standard acrylic paints fail faster here. Look for paints specifically formulated for Florida climates — Sherwin-Williams Emerald Exterior and Benjamin Moore Aura Exterior are both designed for high-humidity environments.
