5 Things That Fail Home Inspections in Arizona — And What They Cost

The Inspection Report Is Not a Deal-Killer — It's Information

I always tell my buyers: the inspection report is supposed to be long and scary-looking. That's what a thorough inspector produces. The question isn't whether there are findings — there will always be findings. The question is which ones are material, how much they cost, and what we can negotiate.

Here are the five items I see flagged most consistently on homes in the Surprise, Goodyear, and broader West Valley area.

1. Roofing: UV Damage and End-of-Life Materials

Arizona's sun is relentless, and it ages roofing materials faster than almost anywhere in the country. Flat roofs (common on ranch-style homes) use elastomeric coatings that crack and blister. Concrete tile roofs develop cracked tiles, failing mortar at the ridgeline, and improper flashing around penetrations.

What it costs: Minor repairs, $500–$2,500. Full re-roof on a typical Surprise home, $12,000–$22,000 depending on size and material. This is the most common big-ticket item I see in negotiations.

2. HVAC: Age and Condition

In Arizona, an air conditioner isn't a comfort appliance — it's critical infrastructure. A failing unit in July is a genuine safety issue. I always ask buyers to note the age of the units (stamped on the data plate on the exterior condenser) and factor replacement cost into their offer if the units are 12+ years old.

What it costs: Full system replacement (interior air handler + exterior condenser), $8,000–$16,000 per system. Two-system homes (common at 2,500+ sq ft) can run $18,000–$28,000 if both need replacement simultaneously.

3. Pool Equipment and Deck Condition

Roughly 40% of homes in the West Valley have a pool. Pools add value and are a legitimate necessity in Arizona summers — but deferred maintenance on pool equipment is one of the most common findings I see.

What it costs: Pump replacement, $800–$1,500. Filter replacement, $400–$900. Replastering (interior pool surface), $6,000–$12,000. Deck resurfacing, $3,000–$7,000. Know what you're buying.

4. Stucco Cracks and Water Intrusion

Stucco is the dominant exterior finish in Arizona, and hairline cracks are normal. But diagonal cracks at window corners, cracks that have been painted over multiple times, or cracks near ground level can indicate structural movement or water infiltration — both of which are more serious.

What it costs: Cosmetic stucco repair, $500–$2,000. If water intrusion has damaged the substrate beneath, $3,000–$10,000+. The inspector should probe suspicious areas; if they don't, ask.

5. Electrical Panels: Older Brands with Known Issues

Homes from the 1960s–80s sometimes have Federal Pacific Stab-Lok or Zinsco electrical panels. Both have documented failure rates and are flagged by insurance underwriters — some companies won't write a policy at all on a home with these panels.

What it costs: Panel replacement, $2,500–$5,000. Almost always worth negotiating as a seller credit given the insurance implications.

My general advice: budget $600–$800 for a quality inspection including a roof specialist if the roof is older, and go in expecting to use your findings in negotiation. That's exactly what the inspection period is for.
