Five reasons to get a roof inspection
1. Pre-purchase (mandatory if your home inspector flags it)
Iowa home inspectors do a general roof check as part of a standard inspection, typically from the ground, the eaves, or by walking the roof if safely accessible. If they flag anything — granule loss, possible hail damage, age concerns, flashing issues — your purchase contract's inspection contingency lets you request a specialist follow-up. A roofer's inspection produces a written scope and remaining-life estimate. Bring that to your negotiation. See our home inspection page.
2. Post-storm (after any significant hail)
After any storm with marble-size (3/4") or larger hail, schedule a post-storm inspection — almost all corridor roofers offer these free, with the understanding that they'll quote you for replacement if damage is confirmed. The inspection serves two purposes: confirming whether you have a claimable loss, and creating documentation if you decide to file. See Iowa hail damage and the claim process.
3. Seller disclosure prep
Iowa requires sellers to disclose known material defects via the Iowa Residential Property Seller Disclosure Statement. If your roof is 10+ years old or has any history of issues, getting a current inspection report before listing serves two purposes: it documents condition for disclosure, and it lets you address findings before a buyer's inspector does. A roof inspection report attached to your seller disclosure can preempt buyer surprises and price negotiations.
4. Insurance renewal
Iowa carriers have tightened their roof condition requirements since 2020. Some now require a roof condition report at certain ages, particularly for older roofs being renewed. Failure to provide one may result in non-renewal or a forced repair before continued coverage. If your carrier asks, comply promptly with a roofer's report — refusal is grounds for non-renewal in most policies. See homeowners insurance.
5. Routine maintenance (every 5-7 years)
On a 20-year roof, a routine inspection at year 7, year 12, and year 17 catches issues — flashing failures, ridge cap loss, isolated shingle damage from windstorms — before they cause interior damage or shorten the roof's life. Worth $150-$300 every several years to extend useful life and avoid surprise leaks.
What an inspector actually checks
| Item | What they're looking for |
|---|---|
| Shingles | Granule loss, blistering, fractures, lift, hail bruising, missing shingles, curling |
| Flashing | Chimney, wall, valley, vent flashing — failure, lift, gaps, rust |
| Ridge cap / ridge vent | Lift, fracture, exposed fasteners, ventilation airflow |
| Soffit and fascia | Rot, paint failure, blockage of soffit vents |
| Gutters and downspouts | Sag, separation, downspout extension, ice dam history |
| Penetrations | Pipe boots, vent caps, satellite mounts, skylights — condition and seal |
| Attic (interior) | Water stains, mold/mildew, ventilation, insulation condition, daylight visibility through deck |
| Deck (visible from attic) | Rot, sagging between rafters, exposed fasteners |
| Age estimate | Years since installation based on shingle type, granule wear, and visible aging |
Cost ranges
- Free post-storm inspection from corridor roofers, typically tied to a quote for replacement if damage is found.
- $150-$400 for a stand-alone inspection by a roofing contractor, written report included.
- $250-$600 for a certified residential roof inspector who does only inspections (no sales) — useful for pre-purchase, insurance documentation, or seller disclosure.
- $200-$500 for drone-only inspections — increasingly common for steep-pitch or hard-access roofs.
- Included as part of a $400-$700 home inspection from an Iowa home inspector (visual only, not specialist-grade).
Iowa storm season at a glance
- March-April: Early hail possible. First windstorms of the year strip loose shingles.
- May-July: Peak hail season. Most claims filed.
- August: Late-season hail and severe thunderstorms.
- September-October: High-wind events from cold fronts. Watch for lifted shingles and ridge cap damage.
- November-March: Snow load, ice dams, freeze-thaw flashing failure. See winter home prep.
What to do with the findings
Minor issues (caulking, isolated shingles, debris)
Most roofers will quote small repairs at $300-$900. Cheap insurance against a $5,000 interior water damage event.
Moderate issues (significant flashing work, partial reroof on one slope)
Get two opinions. A $2,000-$6,000 repair can extend a roof's life 5-10 years if it's the right repair, or paper over a deeper problem if it's the wrong one.
Major issues (widespread granule loss, multiple leaks, hail damage)
Time to plan replacement. If you're inside year 1 of the damage, file an insurance claim — see the claim process. If not, plan a cash replacement using our cost guide.
End-of-life roof (15+ years on a 20-year shingle)
Even without active damage, an end-of-life roof is the right project to schedule before the next storm forces it. Budget time to compare bids, choose materials (see shingles vs metal), and time the work to good weather.
Pre-purchase: what to ask your roofer-inspector
- Age and remaining useful life of the current roof.
- Any signs of hail or wind damage that might be insurance-eligible before closing.
- Decking condition (visible from attic).
- Ventilation adequacy.
- Active or historical leaks.
- Flashing condition at all transitions and penetrations.
- Gutter and downspout condition.
- Estimated cost to bring the roof to "as new" condition vs full replacement.

Frequently asked
When should I get a roof inspection?
Pre-purchase, post-storm (especially after marble-size+ hail), seller disclosure prep on older roofs, insurance renewal triggers, and routine every 5-7 years on older roofs.
What does a corridor roof inspection cost?
Free post-storm from most local roofers. $150-$400 for stand-alone roofer inspection. $250-$600 for inspector-only (no sales). $200-$500 for drone-only.
What does the inspector check?
Shingles, flashing, ridge cap and ventilation, soffit/fascia, gutters, penetrations, attic for leaks, deck condition, age estimate. Written photo-documented report.
Is the home inspector's check enough?
Sometimes. Iowa home inspectors do a general visual roof check. For definitive remaining-life or hail damage scoring, follow up with a roofer specialist. Always follow up if anything is flagged.
When is Iowa storm season?
March-July for hail (peak May-July). October-November for wind. December-March for snow load and ice dams. Most post-storm inspections happen May-August.
