Arizona Monsoon Season: What Every Homeowner Needs to Know

Arizona's monsoon season officially runs from June 15 through September 30, and if you own a home in Phoenix, Scottsdale, Arcadia, or Paradise Valley, you already know what that means: dramatic skies, sudden downpours, haboobs that reduce visibility to zero, and winds that can top 60 mph. The storms are spectacular — and they can be expensive if your home is not ready.

Inspect Your Roof Before June: Your roof takes the brunt of monsoon punishment. High winds can lift loose shingles, and a single heavy rain event can push water into any gap. Walk the perimeter and look for lifted, cracked, or missing shingles from the ground. Check flashing around chimneys, skylights, and vents — this is where leaks most commonly start. Clear debris from valleys and low points where water pools. Schedule a professional inspection if your roof is more than 10 years old. A $150 inspection can prevent a $15,000 repair.

Clear Your Gutters and Downspouts: Arizona homes often go months without rain, so gutters fill with dust, debris, and dried vegetation. When a monsoon hits, clogged gutters overflow and push water against your fascia and foundation. Clean gutters in late May or early June. Extend downspouts at least 4 feet from the foundation. Consider gutter guards if you have mature trees nearby.

Evaluate Your Yard Drainage: Flat or poorly graded yards are a liability in monsoon season. Water should flow away from your foundation, not toward it. Check that the grade slopes away from the house on all sides. Look for low spots in the yard that collect standing water after irrigation — these will flood in a storm. If you have a pool, confirm the deck drains are clear. Gravel yards can shift and create berms that redirect water toward the house — re-grade as needed.

Secure or Remove Outdoor Furniture and Decorations: Monsoon winds routinely exceed 50 mph in the Valley. Anything not anchored becomes a projectile. Bring in lightweight furniture, umbrellas, and potted plants before a storm warning. Anchor or store trampolines — they are one of the most common sources of neighbor property damage during storms. Trim dead branches from trees. A dead limb in a 60 mph gust can go through a window or damage a roof.

Check Your HVAC System: Dust storms coat condenser coils and clog filters, reducing efficiency and shortening equipment life. Replace air filters at the start of monsoon season and again mid-season. Hose down the exterior condenser coils after a dust storm — turn the unit off first. Make sure the condenser pad is level and that the unit has not shifted. If your system is struggling to keep up after a haboob, call an HVAC tech before the next heat wave hits.

Review Your Homeowner's Insurance: Standard homeowner's policies cover wind and rain damage, but there are important gaps to understand. Flood damage is typically not covered by standard policies. If your home is in a flood zone — or even a low-lying area — consider a separate flood insurance policy through the National Flood Insurance Program (NFIP). Sewer backup is also commonly excluded. A separate rider is inexpensive and worth it if your home has a basement or below-grade living space. Document your home's condition with photos or video before the season starts. This makes claims faster and easier.

What to Do During a Storm: Stay inside during a haboob. Dust storms carry bacteria and can cause Valley Fever (coccidioidomycosis) — a fungal lung infection endemic to the Southwest. Pull over and stop if you are driving in a dust storm. Turn off your lights so other drivers do not follow you off the road. Do not drive through flooded washes. Arizona's Stupid Motorist Law allows authorities to bill drivers rescued from flooded roadways. More importantly, just 6 inches of moving water can knock a person down; 12 inches can carry away a small vehicle. Unplug electronics or use surge protectors. Lightning strikes during monsoon storms are common and can fry unprotected devices.

After the Storm — What to Check: Once the storm passes, do a quick walk-around before calling anyone. Check the roof from the ground for obvious damage. Look at window and door seals for water intrusion. Check the garage door — wind can bend tracks and misalign sensors. Inspect the yard for erosion, pooling water, or shifted gravel. Run your HVAC and check that airflow feels normal. If you find damage, document it with photos immediately and contact your insurance carrier before making repairs.

Monsoon season ends September 30, and the Phoenix metro real estate market historically picks up in October as temperatures drop. If you are thinking about listing your home this fall, a pre-monsoon inspection and any needed repairs will put you in a stronger position — buyers notice deferred maintenance, and a clean inspection report removes a major negotiating lever. If you are buying, ask your agent to pull permit history and look for any past roof or water damage repairs. In Arizona, sellers are required to disclose known material defects — but disclosed repairs done properly are not a red flag.
