Monsoon Season Tips for Arizona Homeowners

The best monsoon season tips for Arizona homeowners come down to four things: get the roof and drainage checked before June 15, plan for dust and wind, know how to report a power outage, and set up after-storm checks if the house will sit empty. The National Weather Service defines the season as June 15 through September 30.

I am Terry Day, REALTOR with DeLex Realty. Many of my clients split the year between Arizona and somewhere cooler, and the storms do not wait for your return flight. This is a practical prep list for seasonal and full-time owners. It is not a weather forecast and it is not contractor marketing.

Monsoon season basics

The National Weather Service offices in the Southwest worked together to define the monsoon as June 15 through September 30. Using fixed dates keeps the focus on safety and preparation instead of guessing when the first storm will show up. Actual storm activity varies a lot from year to year, so treat the dates as your prep window, not a promise.

Owners coming from wetter climates often expect long, gentle rain. Monsoon storms tend to be short, intense and windy, and they can bring flash flooding. That is why roof edges, drainage and grading matter more than an annual rainfall number.

Roof and drainage

Before the season starts, or before you leave for the summer:

• Have a qualified roofer inspect the roof for its type: tile, shingle, foam or a coated flat roof all need different checks
• Clear scuppers, channels and debris from flat or low-slope roofs, which are common on older homes in many 55+ communities
• Confirm downspouts and splash blocks send water away from the foundation
• Look at patio covers and Arizona rooms where water can pond against the house
• Check window weep holes and sliding door tracks so they can drain
• Store loose items so moving water and wind cannot carry them off

If you are buying during monsoon season, ask your inspector to look for signs of prior leaks, ceiling stains and grading that slopes toward the home. A storm week is a good time to see how a lot actually drains.

Flood coverage is worth a direct conversation with your insurance agent. The National Weather Service notes that standard homeowners policies generally do not cover flood losses, and flood policies can have a waiting period before they take effect, so this is a spring task, not a July task.

Dust storms and wind

Dust storms cut visibility fast and push grit into weatherstripping, HVAC filters and garage door tracks. Around the house:

• Replace HVAC filters after major dust events
• Keep garage doors balanced and the bottom seal in good shape
• Store patio cushions, umbrellas and lightweight furniture when storms are forecast
• Walk block walls and wrought-iron gates for loose sections after high wind
• Keep papers and electronics off garage floors where dust and water collect

On the road, ADOT's message is "Pull Aside, Stay Alive." Do not drive into a dust storm. If you are caught in one, ADOT says to pull completely off the paved road early, turn off all lights including flashers, set the parking brake, take your foot off the brake and stay buckled in until it passes. Check ADOT's dust storm page for the full guidance each season.

Power outages

Outages happen with monsoon storms. Know which utility serves your home before you need it:

• SRP customers: SRP's outage page and the SRP Power app show outages, customers affected and estimated restoration times, and let you report an outage. SRP also lists a 24-hour outage line at (602) 236-8888 and offers outage alerts through My Account.
• APS customers: Use the Outage Center on aps.com to report an outage or view status, and set up alerts in your APS account.

Both the National Weather Service and SRP suggest turning off or unplugging sensitive electronics so a surge does not damage them when power returns, and keeping the refrigerator and freezer closed during an outage. For a vacant summer home, I also suggest:

• Know what resets on your irrigation controller, thermostat and Wi-Fi devices after an outage
• Ask your electrician about surge protection for major equipment
• Keep freezer inventory low if the house will sit empty for months
• Give your home watch contact the breaker panel location and gate access

Generators and battery systems are owner choices that can involve HOA rules, permits and utility requirements. Confirm with your HOA, the city and your utility before installing one.

What a seasonal owner should arrange before leaving

1. Roof and drainage check
2. HVAC service and a filter change plan
3. Pest treatment suited to a vacant home
4. A home watch schedule that includes visits after storms
5. Any vacancy or absence notice your HOA asks for (check your community rules)
6. A written shutoff map for water, gas and breakers
7. An irrigation timer review so you are not soaking soil against the slab
8. An insurance review covering vacancy terms and flood coverage
9. Utility outage alerts sent to you and your home watch contact

If you plan to sell when you return, summer storm prep protects your fall photos and inspection results. For more on closing up a home, see my summer closing-up checklist, the lock-and-leave condo guide and the retiring to Arizona checklist.

Homes where this checklist matters most

• Older homes with flat or low-slope roofs
• Homes with large patio covers and Arizona rooms
• Seasonal homes left closed from spring to fall
• Lots that sit lower than the street or neighbors

Questions buyers ask

When is monsoon season in Arizona?
The National Weather Service defines it as June 15 through September 30. Storm activity within that window changes every year.

What should I fix first?
Roof leaks and drainage that runs toward the foundation. Those create the most expensive surprises.

Do dust storms damage homes?
Mostly they push grit into filters, seals and door tracks. Plan filter changes and garage door maintenance after big events, and check walls and gates after high wind.

Does homeowners insurance cover monsoon flooding?
The National Weather Service notes that standard homeowners policies generally exclude flood, and flood policies can have a waiting period. Ask your agent well before the season.

Will monsoon issues affect a sale?
Inspectors look for stains, grading and roof condition. Fixing drainage before listing is easier than explaining stains later.
