After a big Calgary hailstorm, roofs get most of the attention. Siding often takes just as much. The August 5, 2024 storm caused $3.35 billion in insured damage (CatIQ final estimate, August 2026), and the Insurance Bureau of Canada has pointed to hail-resistant siding as one of the building improvements for high-risk areas.
This guide covers two things: how to recognise and document hail damage on each type of siding, and the matching problem, which is where a lot of siding claims get complicated. The insurance part is general information about how policies are commonly written in Alberta. Your own policy wording is what actually applies.
What hail does to each material
Hail damage follows the storm's direction. Walls that faced the storm often take the most, and the opposite side can be almost untouched. A consistent pattern helps show the damage came from that storm.
| Material | What to look for |
|---|---|
| Vinyl | Cracks, punched holes and broken corners. Chalky or faded vinyl can show bright spots where hail knocked off the weathered surface. |
| Insulated vinyl | Similar to vinyl. Look for cracks, holes and dents in the face and cracks at the locks. |
| Fibre cement | Chipped paint, fractured corners and cracked boards on hard hits. Exposed grey or white cement at impact points. |
| Engineered wood | Dents in the surface and chipped paint or primer that exposes the wood substrate to moisture. |
| Aluminum and steel | Round dents, most visible in low-angle light. Scratched or chipped finish on steel. |
| Stucco | Chips, spalling and pock marks, and cracks radiating from impacts. Damage to painted or elastomeric finishes. |
| All materials | Spatter marks: clean spots where hail knocked off dirt, oxidation or algae. Spatter shows direction and size of hail, even when the siding isn't damaged. |
How to document hail damage
The Insurance Bureau of Canada advises reporting damage to your insurer as soon as possible, taking photos, keeping receipts for cleanup and temporary repairs, and acting to limit further damage. For siding, organised photos make everything easier.
- When it's safe, note the date and time of the storm, and save any news or Environment and Climate Change Canada warnings for your area.
- Photograph each wall straight on, then label it by direction (north, south, east, west).
- Take close-ups of every crack, hole or dent, with a coin or tape measure in the frame for scale.
- Photograph spatter marks, dented eavestroughs, window screens, vents and fences. They confirm the storm's direction and hail size.
- Keep a few broken siding pieces, and photograph hailstones next to a ruler if you catch them fresh.
- Cover holes or cracked panels to keep water out, and keep the receipts.
- Write down the product name, colour and install year if you have them. They matter for matching.
The matching problem
Say hail cracked the siding on the west and north walls, and the east and south walls are fine. The obvious repair is to replace the damaged walls. The problem is getting the new siding to look like the old.
- Discontinued products. Manufacturers change colours, profiles and textures over time. An older colour may no longer be made.
- Fading. Even when the colour is still made, the old siding has weathered in the sun. New panels from the same line can look noticeably brighter.
- Profile and size changes. A new panel with a slightly different shape or exposure may not lock into the old ones at the corners.
- Trim and accessories. Matching the siding doesn't help if the corners, J-channel or soffit next to it are a different shade.
How Alberta insurance approaches matching
Here's what's documented. Alberta's Insurance Act includes statutory conditions that are part of every property insurance contract in the province. Statutory Condition 13 lets the insurer repair, rebuild or replace damaged property instead of paying, unless a dispute resolution process has started, if it gives written notice within 30 days after receiving the proof of loss. The Act doesn't set a matching rule. So whether undamaged siding gets replaced to keep a uniform look comes down to the wording of your policy and any endorsements.
That wording varies a lot. Some policies include matching coverage. One Canadian insurer's published sample homeowner wording, from Square One, covers reasonable additional expenses to refinish or replace the undamaged portion of exterior roofing, siding, trim, windows or garage doors to reasonably preserve a pre-existing uniform appearance. Other policies reduce what you're paid on siding. Aviva Canada's Alberta Roof and Siding Limitation Endorsement applies an age-adjusted cost factor, similar to depreciation, to vinyl and aluminum siding and to asphalt shingles (other than Class 4 hail-resistant shingles) damaged by hail, wind or the weight of ice, snow or sleet.
This is different from parts of the United States. The National Association of Insurance Commissioners' model claims settlement regulation includes a provision that when replaced items don't match in quality, colour or size, the insurer replaces all items in the area to a reasonably uniform appearance, and some states have adopted matching rules. Don't assume a U.S. article's matching rules apply to your Alberta policy.
If you disagree with the decision
Start by asking the adjuster to explain the decision in writing, with reference to your policy wording. Send your photos, the supplier's confirmation that the product is discontinued, and your contractor's scope.
If that doesn't resolve it, the Government of Alberta lays out the next steps: contact the adjuster's claims supervisor or manager, then your insurer's complaint liaison officer or ombudsperson, and then the General Insurance OmbudService (GIO). Concerns about an insurer's market conduct go to the Alberta Superintendent of Insurance. Alberta's statutory conditions also provide a dispute resolution process for disagreements over the amount of a loss. It can't start until one side has demanded it in writing and the proof of loss has been delivered. See the appraisal clause and roof claim complaints in Alberta.
Will insurance replace all my siding if one side is damaged?
Only if your policy wording provides for it. Alberta's Insurance Act doesn't require matching, so it depends on whether your policy has matching or uniform-appearance coverage, and on any endorsements that limit siding claims. Ask your insurer for the relevant wording.
What if my siding colour is discontinued?
Get written confirmation from a supplier or manufacturer that it's discontinued, and send it to your adjuster with photos. How the insurer responds still depends on your policy, but documented unavailability is stronger than an opinion that it won't match.
How do I know if hail damaged my siding?
Walk around the house after the storm and look at the walls that faced the hail. Look for cracks, holes and broken corners on vinyl, dents on metal, chips on fibre cement and stucco, and spatter marks. Photograph each wall and every impact.
Is hail damage to siding covered by home insurance in Alberta?
The Insurance Bureau of Canada says standard home policies cover damage caused by hail or wind. Your deductible, depreciation terms and any roof and siding endorsement still affect what you're paid.
Who do I complain to about a siding claim in Alberta?
Start with your adjuster's supervisor, then your insurer's complaint officer or ombudsperson. If it's still unresolved, the Government of Alberta points homeowners to the General Insurance OmbudService.
