The Arizona Homeowner's Monsoon Prep Checklist
Protect your home from Arizona's monsoon season with this comprehensive preparation guide. Roof, windows, landscape, and drainage tips from local experts.
Monsoon Season is Coming — Is Your Home Ready?
Arizona’s monsoon season runs from June 15 through September 30, bringing intense thunderstorms, haboobs (massive dust storms), microbursts with winds exceeding 70 mph, and flash flooding. Each year, monsoons cause millions of dollars in home damage across the Valley.
The good news? Most monsoon damage is preventable with proper preparation. Here’s your complete checklist.
Roof Inspection & Repair
Your roof is your first line of defense. Before monsoon season:
- Inspect for damaged or missing tiles/shingles — Even small gaps allow water intrusion
- Check flashing around vents, skylights, and chimneys — the most common leak points
- Clear roof debris — Leaves, branches, and dust can clog drainage
- Inspect flat roof coatings for cracks, bubbles, or peeling
- Schedule professional inspection if your roof is over 10 years old
Window & Door Sealing
- Check weather stripping on all doors and windows
- Inspect window caulking and replace if cracked or missing
- Test window locks — properly latched windows resist wind better
- Consider impact-resistant film for large windows in exposed areas
Landscape & Drainage
- Trim trees within 15 feet of your home — dead branches become projectiles
- Secure loose items — patio furniture, trash cans, decorations, umbrellas
- Clear gutters and downspouts — ensure water flows away from your foundation
- Check grading — soil should slope away from your foundation on all sides
- Inspect irrigation for leaks that could saturate soil near your foundation
Electrical & Solar
- Test your GFCI outlets — especially outdoor and garage outlets
- Have solar panels inspected — loose mounting hardware or damaged wiring can be dangerous in high winds
- Consider a whole-home surge protector — monsoon lightning causes thousands of surge damage claims yearly
- Test backup generator or battery system if you have one
Emergency Preparedness
- Know your shutoff locations — main water, gas, and electrical panel
- Keep emergency supplies — flashlights, batteries, water, first aid kit
- Document your home — photograph rooms and valuables for insurance purposes
- Review your homeowner’s insurance — understand what’s covered and what’s not
When to Call a Professional
Don’t wait until the first storm hits. Schedule inspections and repairs now, while contractors have availability. After monsoon season starts, demand for roofing and emergency repairs spikes dramatically.
