How often should you get your roof inspected in Texas?

There's no NRCA- or ARMA-backed answer to how often a roof needs inspecting — the popular "twice a year, spring and fall" rule has no association citation behind it. What actually determines timing: NRCA's documented warning signs, ARMA's 20-year reroofing threshold, and IBHS's finding that sub-severe hail leaves roofs measurably more vulnerable.

There’s no NRCA- or ARMA-backed answer to how often a roof needs inspecting in Texas. The “twice a year, spring and fall” rule that gets repeated across roofing sites has no association citation behind it. What actually determines timing is three things the record does support: the National Roofing Contractors Association’s (NRCA) documented warning signs, the Asphalt Roofing Manufacturers Association’s (ARMA) 20-year reroofing threshold, and IBHS’s finding that even sub-severe hail leaves a roof measurably more vulnerable to later damage. Here’s what each of those actually says, and where the widely repeated claim falls short.

Where does the “twice a year” rule come from — and why can’t we verify it?

The “inspect your roof twice a year, in spring and fall” rule shows up across roofing blogs and contractor sites, but neither NRCA nor ARMA publishes an inspection-frequency standard behind it — no primary source names that specific cadence, so it can’t be verified as fact.

This is one of the most-repeated pieces of roofing advice online, and it’s easy to see why — a seasonal check sounds sensible on its face. But sounding sensible isn’t the same as being sourced. Neither NRCA’s roofing guidelines page nor ARMA’s FAQ page names a specific inspection interval, seasonal or otherwise, and no other primary industry association in this corpus fills that gap either. Until a primary source actually publishes a cadence, treating “twice a year” as an established standard overstates what’s actually known.

What do NRCA and ARMA actually say about roof inspections?

NRCA names specific warning signs worth checking for — cracked, warped, or missing shingles, loose seams, deteriorated flashing, and granules collecting in gutters or downspouts — while ARMA calls any roof over 20 years old “a prime candidate for reroofing.” Neither association ties either point to a calendar-based inspection schedule.

NRCA’s warning signs are specific enough to act as a real checklist: cracked, warped, or missing shingles; loose seams; deteriorated flashing; and granules collecting in gutters or downspouts. ARMA’s complementary guidance lists which localized problems are typically repairable without a full tear-off — debris-damaged shingles, backed-out fasteners, damaged flashing, and wind-damaged seals — against NRCA’s line that a complete roof-system failure “generally is irreversible.” Combined with ARMA’s 20-year reroofing benchmark, that’s a condition- and age-based framework, not a calendar-based one.

When is a roof inspection clearly warranted?

A roof inspection is clearly warranted after any hailstorm, even a mild one. IBHS impact testing found that sub-severe hail under 1 inch can strip protective granules and make a roof up to ten times more susceptible to damage from a later, larger storm — one concrete, sourced reason to check after every hail event.

The Texas Department of Insurance’s own post-storm guidance assumes a damage check happens right away: photograph and video everything before any cleanup, hold off on throwing away damaged material until an adjuster has seen it, make only temporary repairs, and get multiple contractor bids to compare against the adjuster’s report. Combine that with NRCA’s warning signs and ARMA’s 20-year age benchmark, and three clear triggers emerge: after a hailstorm or high-wind event, once any of NRCA’s specific warning signs appear, and once a roof passes 20 years old. See our Storm & Hail Damage page for the insurance-claim side of a post-storm check.

What does a roof inspection actually look for?

A roof inspection looks for the same things NRCA and ARMA identify as trouble: cracked, warped, or missing shingles, loose seams, deteriorated flashing, granules collecting in gutters or downspouts, and localized damage such as backed-out fasteners or wind-damaged seals. Those findings determine whether a repair or a full replacement makes sense.

In practice, that means a look for NRCA’s specific signs — cracked, warped, or missing shingles, loose seams, deteriorated flashing, and granule buildup in the gutters — cross-checked against ARMA’s repairable-damage list and the roof’s age against ARMA’s 20-year benchmark. NRCA’s caveat that actual service life “depends on local climatic and environmental conditions, proper design, material quality and suitability, proper application and adequate maintenance” is why the same age, on two different roofs, can mean two different answers.
