Get a roof inspection twice a year in Arizona, once in spring before monsoon season and once in fall after it, plus an extra check any time a major wind or hail storm rolls through. That baseline holds for most roofs; older roofs, flat and foam roofs, and rental properties need to lean toward the more frequent end of that range. Here's the full breakdown by roof type, age, and season.
Recommended inspection frequency by roof type
| Roof type | Standard schedule | Roof over 15 years old |
|---|---|---|
| Asphalt shingle | Twice a year | Twice a year, closer inspection each visit |
| Concrete or clay tile | Twice a year | Twice a year, plus underlayment check |
| Flat / foam roofing | Twice a year, or quarterly on commercial buildings | Quarterly, watch coating wear closely |
| Metal (standing seam) | Once a year, plus post-storm checks | Once or twice a year |
Every roof type also needs an additional check after any storm involving sustained wind, hail, or a haboob dust event, regardless of where it falls in the regular schedule. See our full monsoon roof damage guide for what that kind of storm actually does to each material.
What a professional inspection actually checks
- Roofing surface condition — cracked, curling, or missing shingles; slipped, cracked, or displaced tile; blistering or ponding on flat/foam roofs; loose seams on metal.
- Flashing — around chimneys, vents, skylights, and roof-to-wall joints, where the majority of leaks actually start.
- Gutters and drainage — clogs, sagging, or improper pitch that can back water up under roofing material.
- Attic and ventilation — checking for daylight gaps, moisture staining, inadequate airflow, or insulation compressed by past leaks.
- Decking condition — visible sagging, soft spots, or staining that indicates moisture is getting past the roofing surface.
- Sealant and penetration points — pipe boots, satellite mounts, and any roof penetration where sealant naturally degrades under UV exposure.

A twice-yearly schedule is a baseline, not a reason to ignore something obvious in between visits. Get a roof looked at right away if you notice:
- A new ceiling stain, even a small one
- Granules collecting in gutters or at downspouts
- Visible daylight through the attic decking
- A musty smell in the attic or top-floor rooms
- Cracked, slipped, or missing tile visible from the ground
- Debris impact from a storm, even without an obvious hole
Our guide on how to spot a roof leak before monsoon season covers these warning signs in more depth.
DIY visual check vs. professional inspection
A homeowner can safely handle a basic visual check between professional visits: walk the perimeter with binoculars looking for obviously displaced material, check the attic for staining or light gaps, and confirm gutters are clear. What a DIY check misses is anything that requires walking the roof surface itself or specialized tools — hairline tile cracks, underlayment failure not yet visible as a leak, or soft decking that only shows up under foot pressure or a moisture meter. Climbing onto a roof without training and proper fall protection isn't worth the risk for a check that a professional can do safely and more thoroughly.
How monsoon season changes the schedule
Arizona's monsoon season, roughly mid-June through September, is the single biggest reason the twice-a-year rule exists. A spring inspection catches winter wear and confirms the roof is ready for high wind and heavy rain events before they arrive. A fall inspection, right after monsoon season winds down, catches anything the season's storms caused that wasn't obvious enough to trigger an emergency call. Skipping the fall check is one of the more common mistakes homeowners make, since a roof can look fine from the ground while carrying storm damage that only shows up as a leak months later during the next rain.
New roof vs. older roof — different cadence
A newly installed roof still benefits from a first-year inspection to confirm everything is settling and sealing as expected, then the standard twice-yearly schedule after that. As a roof crosses 15 years for shingle, or its underlayment approaches 20-25 years for tile, inspections become more about catching problems before they compound, not just routine maintenance. At that stage, an inspection can also help determine whether a repair is still sufficient or whether the roof is approaching the point where full replacement makes more financial sense. Our guide on signs you need a full roof replacement walks through that decision in more detail.
What a roof inspection costs
Many roofing contractors, including this one, offer a standard visual inspection at no cost, since it's also how an accurate repair or replacement quote gets built. More detailed reports, such as those built for an insurance claim or a real estate transaction and involving moisture scanning or a written photo report, sometimes carry a separate fee that varies by scope. It's worth asking directly what's included before scheduling if documentation is the goal, as covered in our insurance claim guide.
Landlords and rental properties
Rental and multi-unit properties, common near the ASU area, carry a specific risk that owner-occupied homes don't: tenants often don't report small early warning signs like a faint stain or a musty smell, simply because they don't think to. A documented twice-yearly inspection schedule closes that gap, catching problems while they're still a minor repair instead of letting them escalate into a major one discovered only at move-out or during a bigger storm.
Checklist: what to ask an inspector
- ☐ Is the inspection visual only, or does it include the attic and flashing points?
- ☐ Will I get a written report with photos, or just a verbal summary?
- ☐ Is there a fee, and what does it cover versus a standard free inspection?
- ☐ If damage is found, is there a clear written estimate before any work starts?
- ☐ Does the report note age-related wear separately from storm-related damage? (Useful if a claim ever comes up.)
What skipping inspections actually costs
| Factor | Regular inspections | Skipping inspections |
|---|---|---|
| Small issues (cracked tile, loose flashing) | Caught and repaired early, low cost | Often missed until a leak develops |
| Insurance claim documentation | Clear before/after condition on record | Harder to prove cause was sudden, not gradual |
| Long-term cost | Lower — repairs stay small | Higher — deferred issues compound into bigger repairs |
Final thoughts
Twice a year, plus after any major storm, is the schedule that actually prevents small roof problems from becoming expensive ones in Arizona's climate. The exact cadence shifts a little by material and age, but the underlying logic doesn't change: a roof exposed to this much sun and this much monsoon wind needs eyes on it more than once a decade, and a free inspection is the lowest-cost way to know exactly where a specific roof stands.
