The standard answer from roofing professionals is "twice a year" — once in spring and once in fall. The honest answer is that the right frequency depends on your roof's age, your climate, and what happened last season. Here's how to think about it.
The Baseline: Once Per Year Minimum
For most homeowners with asphalt shingle roofs in moderate climates, one professional inspection per year is the appropriate baseline. Annual inspections:
- Catch minor issues — failed pipe boots, cracked sealant, lifted ridge cap — before they cause water intrusion
- Document the roof's condition over time, which is valuable for insurance purposes
- Identify sections approaching end of useful life before they fail unexpectedly
- Keep you within most manufacturer warranty requirements (some require documented inspections)
The cost of a professional inspection from a reputable contractor is typically $0–$150, and many contractors offer free annual inspections as part of their maintenance relationship. The cost of missing a failing pipe boot until it produces interior water damage is routinely $2,000–$8,000 in drywall, insulation, and mold remediation.
When to Inspect More Frequently
After Any Significant Storm
This is the most important trigger for an unscheduled inspection. Any storm with reported hail at 1 inch or larger, wind gusts above 60 mph, or heavy ice accumulation warrants a professional inspection within 7–14 days — regardless of whether you see obvious damage from the ground. See our post-storm inspection guide for details.
Roofs Over 15 Years Old
As asphalt shingles approach the end of their rated life, the rate of deterioration accelerates. A shingle at year 20 degrades faster per year than the same shingle at year 10. For roofs in their final quarter of expected life, semi-annual inspections help catch the failure modes — cracking, excessive granule loss, failed flashings — that signal impending replacement before they produce active leaks.
Active Weather Markets
Homes in hail-active markets (DFW Metroplex, Front Range Colorado, Oklahoma, Kansas City, Minneapolis) should inspect after every significant convective weather season — typically post-spring and post-fall storm seasons. In these markets, cumulative hail impact over 3–4 seasons may not produce immediately obvious damage but does shorten roof life measurably.
After Tree Work or Structural Changes
Tree trimming, addition construction, rooftop HVAC work, satellite dish installation — any activity that puts equipment or personnel on or near the roof can cause incidental damage that warrants a documented inspection.
Spring vs. Fall: What to Check Each Time
| Inspection Timing | Primary Focus |
|---|---|
| Spring (post-winter) | Ice dam damage, lifted shingles from freeze-thaw, granule loss from snow/ice abrasion, flashing movement from thermal cycling, gutter rehang from ice weight |
| Fall (pre-winter) | Debris clearing, gutter cleaning, sealant condition at all penetrations, pipe boot condition, any summer storm damage, general condition heading into freeze season |
| Post-storm (any season) | Hail impact marks, lifted/missing shingles, ridge cap displacement, soft metal dents, flashing separation |
Can You Inspect Your Own Roof?
A ground-level self-inspection — using binoculars or a drone if you have one — is valuable as a supplement to professional inspections, not a replacement. From the ground you can see:
- Missing or visibly curled shingles
- Ridge cap sections that have lifted or displaced
- Granule accumulation in gutters (visible when cleaning them)
- Obvious flashing separation at chimneys or dormers
What you cannot see from the ground: hail bruising on shingle surfaces, broken seal tabs on otherwise flat-appearing shingles, pipe boot cracking, early-stage decking deterioration, and the majority of flashing details. A professional with roof access sees what you can't.
What a Professional Inspection Should Cover
- All slopes walked and visually assessed
- Ridge cap condition — adhesion, granule loss, any displacement
- All pipe boots and penetration flashings checked for cracking or lifting
- Chimney, wall, valley, and step flashings examined for separation or corrosion
- Gutter and fascia condition assessed
- Soffit and ventilation openings checked (insects, blockages)
- Attic inspection if access is reasonable — signs of moisture, daylight, or ventilation issues
- Written report with photographs provided
- Roof under 15 years, moderate climate: once per year
- Roof over 15 years, any climate: twice per year (spring + fall)
- Any roof in hail-active market: after every significant storm season
- Always: within 14 days of any storm with 1"+ hail or 60+ mph wind
