Roof Inspection & Maintenance
Your roof is your first line of defense. Before monsoon season begins, inspect or hire a roofer to check: tile mortar and sealant integrity (cracked mortar is the #1 roof leak source in Mesa), flashing around pipes, vents, and chimneys, flat roof drainage and ponding potential, and roof valley conditions where water concentrates during heavy rain.
Mesa-specific tip: UV exposure degrades roof sealant faster here than in most climates. If your roof sealant hasn't been inspected in 3+ years, schedule a professional evaluation before June.
Gutter & Downspout Clearing
Mesa's desert landscaping doesn't produce traditional leaf debris, but palo verde flowers, mesquite pods, and blown dust accumulate in gutters and downspouts. Clean all gutters and ensure downspouts direct water at least 3 feet away from the foundation. Consider adding downspout extensions to channel water further from the home.
Grade & Drainage Check
Walk the perimeter of your home during dry conditions. Ground should slope away from the foundation at a minimum 1-inch drop per foot for the first 6 feet. If you see low spots, settled areas, or soil that slopes toward the foundation, add soil to correct the grade before storms arrive. This is the single most effective monsoon flood prevention measure for Mesa homes.
Foundation Inspection
Inspect your foundation for cracks, gaps, or deteriorated mortar joints. Even small cracks can channel monsoon water into your home. Seal visible cracks with appropriate foundation sealant. For Mesa's slab-on-grade homes, check the joint where the slab meets the stem wall — this is a common entry point for monsoon water.
Window & Door Seal Check
Mesa's monsoon storms often include strong wind-driven rain. Check weatherstripping and caulking around all windows and exterior doors. Replace any that's cracked, peeling, or has gaps. Sliding glass doors are particularly vulnerable — clean and lubricate tracks, and ensure the weep holes at the bottom of the track are clear.
AC System Maintenance
Your AC unit runs hardest during monsoon season. Have it serviced before June: clear the condensate drain line (pour vinegar through it monthly), check the drip pan for cracks, ensure the condensate pump works if equipped, and verify the emergency overflow switch functions. AC condensate overflows are one of the top 3 residential water damage causes in Mesa.
Interior Preparation
- Know your main water shut-off location — practice turning it off
- Store important documents above ground level or in waterproof containers
- Keep a battery-powered radio and flashlight accessible (monsoons cause power outages)
- Consider a water leak detection system for high-risk areas
- Save our emergency number: (480) 907-0441
