Post-Hail Commercial Roof Inspection Protocol

Quick Answer: After a Calgary hail event with stones 25 mm or larger, property managers should photograph exterior damage within 48 hours, notify insurance carriers, restrict roof access, schedule a HAAG Certified inspection within 7 days, and file claims with documented reports within 30 days. Late reporting is the most common reason commercial hail claims are denied or depreciated. Calgary averages 8 to 12 hail events per summer, according to the Insurance Bureau of Canada data.

A hail event sets a 30-day clock running on most commercial insurance claims. Following a structured post-hail commercial roof inspection protocol helps property managers preserve evidence, document damage correctly, and strengthen the claim from the outset. The actions taken in the first 48 hours often determine whether a six-figure claim is paid in full, depreciated, or denied. This article gives the step-by-step protocol, the documentation that matters most, and the common mistakes that destroy claim value.

At a Glance

Quick Facts:

• Damaging hail threshold: 25 mm stones (Insurance Bureau of Canada)

• Total-loss threshold: 40 mm+ stones typically total a roof

• Insurance reporting window: Typically 30 days from the event

• Inspector credential preferred: HAAG Certified Inspector

• Calgary hail events per summer: 8 to 12 (Insurance Bureau of Canada)

• Documentation impact: Pre-event records improve claim outcomes substantially

Hour 0 to 48: Immediate Response

The first 48 hours focus on evidence preservation, not inspection.

1. Document the event. Note time, date, duration, and stone size if witnessed or measurable. Environment Canada hail reports for the date can corroborate.

   
   

2. Photograph exterior damage. Building siding dents, dented HVAC fins, shredded window screens, dented metal flashings, damaged vehicles on the lot, and any visible roof damage from ground level. These corroborate hail intensity for insurance.

   
   

3. Notify insurance carrier. Notice of potential claim. This does not commit to filing but starts the policy's response process and protects the reporting window.

   
   

4. Restrict roof access. Lock rooftop hatches. Prohibit HVAC service traffic until inspection is complete. Insurance scopes treat post-event roof traffic as suspicious and may reduce settlements if non-hail damage is created during the response window.

   
   

5. Notify tenants. If interior leaks have been reported, document the locations. Tenant-reported damage adds corroborating evidence to the claim.

   
   

6. Do not begin repairs yet. Emergency tarping to prevent water intrusion is acceptable; permanent repair before inspection compromises evidence.

Day 2 to 7: Inspection Scheduling

Schedule the inspection within 7 days when possible.

1. Use a HAAG Certified Inspector. HAAG certification is the credential Alberta commercial insurance adjusters reference most often. HAAG inspectors produce reports formatted to insurance scope standards and carry weight in claim disputes.

   
   

2. Confirm scope match. Hail scope inspections are not maintenance inspections. They focus on impact damage documentation: hit count, hit density per 100-square-foot test square, damage severity per hit, and progression of damage compared to pre-event condition.

   
   

3. Pull pre-event documentation. Previous inspection reports, warranty documents, original installation specs, and any maintenance records. These establish a baseline condition.

   
   

4. Coordinate with the insurance adjuster. Many carriers prefer to attend the inspection. Scheduling for joint attendance often accelerates claim resolution.

   
   

5. Document tenant interior damage. Any drywall staining, ceiling tile damage, or equipment damage from leaks should be photographed and dated.

   
   

Day 7 to 30: Inspection and Filing

The inspection and report production typically take 7 to 14 days.

1. On-site inspection. Full 6-zone walkthrough plus hail-specific testing. Test squares (typically 3 metres by 3 metres or 10 ft by 10 ft) on each roof slope or section, with hit count per test square recorded. Damage severity per hit photographed. Substrate testing where appropriate.

   
   

2. Report production. Documents hit density, damage severity by zone, recommended repair vs replacement, and estimated remaining service life under different repair scenarios.

   
   

3. Claim filing. Submit claim with inspection report, photos, pre-event documentation, and tenant damage evidence. Most carriers acknowledge claims within 5 business days.

   
   

4. Adjuster reinspection. A carrier-assigned adjuster typically performs an independent or joint inspection. HAAG-formatted reports support direct comparison.

   
   

5. Scope agreement. The repair vs. replacement decision is typically negotiated based on hit density (industry rule of thumb: 8+ hits per 100 sq ft test square often triggers replacement consideration). Final scope and pricing are settled before work begins.

   
   

What HAAG Inspections Document Specifically

HAAG protocols are the industry standard for hail damage assessment. Their reports document:

Test square methodology

Defined test squares on each roof section with hit count per square. Documents whether damage is concentrated or distributed.

Hit categorization

Each hit is categorized as functional damage (compromises waterproofing) or cosmetic damage (surface mark without function loss). Insurance pays only for functional damage on most policies.

Severity per hit

Damage is rated by depth, fracture pattern, and substrate exposure.

Cross-reference with non-roof damage

Building exterior damage, HVAC fin damage, window screen damage, and vehicle damage all support the hail intensity claim.

Storm corroboration

Environment Canada hail reports, Insurance Bureau of Canada storm database, and local news reports cross-referenced for the event date.

A HAAG-formatted report is typically 20 to 60 pages with hundreds of photos. It's the documentation standard most Alberta carriers prefer.

Common Mistakes That Destroy Claim Value

Several mistakes consistently reduce commercial hail claim outcomes.

1. Late reporting. Reporting outside the policy window (often 30 days, sometimes shorter) can void the claim entirely or limit recovery to a percentage.

   
   

2. Repairs before inspection. Permanent repairs eliminate evidence. Emergency tarping is acceptable; permanent repair is not.

   
   

3. Multiple contractors on the roof post-event. Each contractor walking on the roof can damage the hail-bruised membrane further and create disputes about the origin of the damage. Restrict access to inspection personnel only.

   
   

4. Using a non-HAAG inspector for high-value claims. Non-HAAG reports carry less weight in disputes. The cost difference is small compared to the potential claim recovery on commercial buildings.

   
   

5. No pre-event documentation. Without baseline condition records, depreciation arguments become difficult to refute. Maintenance program documentation is the best defence.

   
   

6. Accepting the first scope without negotiation. Initial adjuster scopes often understate damage. HAAG-formatted reports support negotiation for full-scope recovery.

   
   

7. Treating the roof as the only damaged asset. Hail damages HVAC fin coils, exterior siding, window screens, and rooftop equipment. Each represents a separate covered loss under most commercial property policies.

   
   

Stone Size and Expected Damage

Stone size correlates roughly with damage expectations.

Stone size	Expected damage
Under 15 mm	Minimal; some weathering acceleration possible
15 to 24 mm	Cosmetic damage; some bruising on aged membranes
25 to 39 mm	Functional damage common; insurance threshold
40 mm +	Total replacement is often required on aged membranes
50 mm +	Total replacement is typical regardless of membrane age

Hail events in Calgary have produced stones over 100 mm in recent severe seasons. Damage at that scale typically includes structural concerns beyond the membrane.

Tenant Communication Template

Commercial property managers should pre-draft tenant communications for hail events.

1. Within 24 hours of the event. Notification that an inspection is being scheduled. Request tenant reports of any visible interior damage. Provide a contact for incident reporting.

   
   

2. Within 7 days. Update on inspection scheduling. Estimated timeline for inspection and claim filing.

   
   

3. Within 30 days. Update on inspection findings and repair scope. Coordinate any access requirements for repair work.

   
   

4. During repair. Daily or weekly updates on work progression, especially where tenant operations are affected by noise, dust, or rooftop access restrictions.

   
   

Clear tenant communication reduces friction during the claim process, supports landlord-tenant lease compliance, and complements the post-hail commercial roof inspection protocol by keeping occupants informed throughout the inspection, claim, and repair process.

Frequently Asked Questions

How do I confirm a hail event was severe enough to warrant inspection?

The Insurance Bureau of Canada and Environment Canada both track significant hail events. Stones of 25 mm or larger generally warrant inspection regardless of visible damage. When in doubt, inspect; the cost is small relative to potential undetected damage.

My client wants to use their own inspector. Can I use my own, too?

Yes, and you should. The carrier's adjuster works for the carrier, not for you. Your own HAAG Certified inspector provides independent documentation that supports negotiation. Many policies allow reasonable inspection costs as part of the claim.

What if my roof has prior unfiled damage from previous hail?

This is common in Calgary. The current claim covers current event damage; prior damage is typically excluded as a pre-existing condition. This is why post-event inspection after every significant hail event matters; unfiled prior damage becomes harder to claim later.

How long does the claim process typically take?

Simple claims (clear damage, agreed scope) settle within 30 to 60 days. Complex claims (disputed scope, total-loss determination, multiple buildings) can take 6 to 18 months. Active documentation throughout the process is essential.

What about business interruption coverage?

Commercial policies often include business interruption coverage when roof damage causes tenant or operational disruption. Document tenant impact carefully. Notify the carrier of business interruption claims separately from property damage claims.
