Quick Answer: After a Calgary hailstorm, photograph your siding within 24 hours, file your insurance claim within 48 hours, and get an independent contractor assessment within the first week. Hail damage on siding looks like dents, cracks, or splits on vinyl; impact marks or cracks on Hardie; and round dimples on ACM. Most Alberta policies cover hail damage repair or replacement, with deductibles typically ranging from $1,000 to $5,000.
A Calgary hailstorm hits siding harder than most homeowners realize. The roof gets most of the attention, but siding takes parallel damage that's often missed in initial assessments. Vinyl cracks. Hardie planks split. ACM dents. Older aluminum shows obvious dimples. Hail damage to siding can also hide behind intact-looking panels as broken sealant joints that lift in the next windstorm. This guide walks through what hail damage looks like by material, the action sequence after a storm, what insurance covers, and how to avoid the storm-chaser scams that flood Calgary neighbourhoods after major events.

Claim filing window: 1 to 2 years on most Alberta policies; file within 48 hours
Calgary deductible range: $1,000 to $5,000, typical
Hail size that damages siding: 15 mm and up regularly damages vinyl
Major Calgary storm seasons: 2020, 2021, 2024
Hail Damage Signs by Siding Material
Different materials show hail damage differently.
Vinyl. Hail impacts crack, split, or punch holes in vinyl panels. The damage is usually clearly visible on close inspection. Patterns include:
Cracks radiating from a central impact point
Splits running along panel locks (often where panels are weakest)
Punched holes in the panel face
Broken locking edges that no longer hold the panel to the wall
Concealed hail damage where the panel face looks intact, but the lock or backing has fractured
Vinyl becomes more brittle in cold weather. Hailstorms in shoulder seasons (May, September) often cause more vinyl damage than mid-summer storms of the same hail size.
Hardie board. Fibre cement resists hail better than vinyl but isn't immune. Damage patterns:
Impact craters on the panel face (visible, round depressions)
Hairline cracks radiating from impacts
Broken planks at the bottom edge, where impact concentrates stress
Chipped paint at impact points (more visible on ColorPlus than paint-grade)
Fractured plank ends near butt joints
Hardie damage often looks less dramatic than vinyl but indicates similar impact severity. Don't assume Hardie is undamaged just because no cracks are obvious from the ground.
ACM panels. Aluminum composite material dents under hail.
Round dents visible on close inspection (more obvious in raking light)
Crease lines where multiple impacts compounded
In severe hail, the piercing of the outer aluminum skin
Damage to the joint sealant at panel edges
ACM hail damage is often cosmetic rather than functional. Whether insurance replaces dented ACM panels varies by adjuster and policy.
Older aluminum siding. Calgary homes from the 1970s and 1980s with original aluminum siding take obvious hail damage: dimples, dents, and creases that show clearly from the ground. Aluminum siding is rarely repaired today; damage usually justifies replacement with a modern material.
The First 72 Hours After the Storm
Speed matters. The action sequence:
Document before water touches it. Walk the exterior with a camera. Photograph every wall, including close-ups of damage and wide shots showing the full elevation. Include date and time stamps. Photograph the hail with a coin for scale.
Check the interior. Look at ceilings, attics, around chimneys and skylights, and at exterior wall surfaces. Photograph any watermarks, paint blistering, or interior signs of envelope failure.
Call your insurance company within 48 hours. Get your claim number, adjuster contact, and confirm policy structure (ACV or RCV, matching endorsement, deductible).
Tarp emergencies. If wind or rain is entering, temporary tarping is typically covered as a claim expense.
Get an independent contractor assessment. Schedule this in the first week. The assessment runs parallel to the adjuster's inspection, not after it.
Avoid door-knockers. Storm-chasers blanket Calgary neighbourhoods within 48 hours of major events. Don't sign anything with anyone who knocks on your door in the first week.

Filing a Calgary Insurance Claim on Siding
Alberta homeowners' insurance typically covers hail damage to siding. The claim process:
Call the insurer or your broker. Initial claim opens with basic information about the storm date and damage scope.
Adjuster inspection scheduled. After major storms, adjuster availability is tight. Document your damage thoroughly to keep the claim moving even before the inspection.
Contractor assessment in parallel. Independent documentation often surfaces damage that the adjuster's quick inspection misses. Photo-documented findings from a reputable contractor strengthen the claim scope.
The adjuster writes a scope of work. Specifies what's covered, in what dollar amount, for repair or replacement.
Homeowner reviews and approves. You can question scope items, request supplemental review, or negotiate the scope.
Work proceeds. Contractor schedules work based on the approved scope. Payment flows from insurer to homeowner (or directly to contractor, depending on policy structure).
Final inspection and closeout. Some insurers do a post-completion inspection before final payment.
Key policy details to confirm:
ACV vs RCV. Replacement Cost Value pays the full repair cost. Actual Cash Value depreciates by age.
Matching endorsement. Some policies pay for full-wall or full-elevation replacement when matching isn't possible. Confirm in your policy language.
Deductible. Typically $1,000 to $5,000 in Calgary, often with separate hail/wind deductibles.
Roof-and-siding limitation endorsements. Some carriers cap payouts on aging siding. If your policy carries this and your siding is 15+ years old, expect a lower payout.
Repair vs Replacement After Hail
The repair-or-replace decision after hail uses the same framework as non-storm decisions, modified by:
Insurance scope. The adjuster's scope sets the financial framework. Homeowner preference can shift the scope through documentation and negotiation, but doesn't override it entirely.
Matching availability. Discontinued colours often justify wall-level or full-house replacement under matching endorsements.
Compounded damage. Storm damage on aging siding often pushes the math toward replacement because the existing material is approaching end-of-life anyway.
Insurance discount opportunity. Class 4 hail-rated vinyl, Hardie, and ACM all qualify for premium discounts with some Alberta insurers. The upgrade-during-repair window is the best time to capture these.
Common scenarios:
Light damage on younger siding: repair, capped by 30% rule
Moderate damage on the younger siding: repair or section replacement
Widespread damage at any age: full replacement
Any damage on aging siding (15+ years): replacement, often with an upgrade to a higher-grade material
Matching not available: wall-level or full replacement based on policy matching terms
Avoiding Post-Storm Scams
After hail damage to Calgary siding, storm chasers often target homeowners. Verify any contractor before signing to help protect your property and insurance claim.
Calgary's storm seasons attract storm chasers who target damaged neighbourhoods. The patterns to watch for:
Door-knocking with offers to inspect for free. A real Calgary contractor doesn't door-knock. Reputable companies have full schedules from existing customers and inbound calls.
Deductible waivers or "free roofs." Illegal in Alberta. Insurance fraud.
Pressure to sign on the spot. Contracts signed under pressure rarely favour the homeowner.
Out-of-province plates and phone numbers. Crews from outside Alberta set up temporary local offices after storms and leave before warranty issues surface.
Demands for large upfront deposits. Industry standard is 10% to 30%. Demands for 50%+ upfront are a warning sign.
Quotes far below the local market. A real Calgary contractor can't profitably underbid the market significantly.
Vague warranty terms. "Lifetime warranty" without specifics, or warranties tied to companies that won't exist in 2 years.
The pragmatic approach: work with a contractor who has a visible Calgary presence (physical address, long-term phone number, AARA or BBB membership, recent local work you can verify), and who doesn't pressure you to sign immediately. After a major storm, schedule 2 to 3 written quotes within 2 weeks of the event.
Frequently Asked Questions
Can hail crack vinyl in cold weather?
Yes, more readily than in warm weather. Vinyl becomes more brittle below -20°C. Calgary hail in shoulder seasons (May and September) often produces more vinyl damage than mid-summer storms because the material is colder. Hail-rated vinyl and thicker grades resist cold-weather impact better than entry-level products.
Will my premium go up?
Possibly modestly. Single hail claims in widespread Calgary storm events often don't trigger individual premium increases because Calgary's hail risk is priced into the base premium. Repeated claims on the same property can affect renewal rates. Ask your broker about your specific situation.
Should I file siding and roof under one claim?
Yes. One claim for all damage from one storm event is the standard approach. The adjuster scopes all damage together, applies one deductible, and processes one settlement. Splitting into separate claims doubles deductibles and doesn't typically help the homeowner.
How long do I have to file?
Most Alberta homeowners' policies allow 1 to 2 years from the date of loss. Filing within 48 to 72 hours is strongly recommended because adjuster availability tightens after major storms, and evidence of damage can deteriorate. Late claims based on newly discovered damage are accepted under most policies but require strong photo documentation tied to the original storm event.
