The part of the house nobody looks at, doing two jobs that both matter.
Soffit is the underside of your roof overhang and fascia is the board at its edge. Between them they do two things that decide how long your roof lasts: soffit vents let cool air into the attic, and fascia carries the eavestrough.
Both get skipped constantly on hail claims because you have to stand underneath and look up to see the damage. An adjuster walking the property at eye level does not see punctured soffit panels. It's one of the most reliably under-documented items on an exterior claim.
Attic ventilation works as a system: cool air enters low at the soffit, warms, rises, and exits high at the ridge. Block the intake and the whole thing stops. Blown-in insulation pushed over the soffit vents during an energy retrofit is the most common cause we find, and the result is an attic that runs hot in summer — cooking shingles from underneath and shortening their life — and damp in winter, which produces frost on the sheathing and ice dams at the eave.
Fascia board takes the weight of a full eavestrough, and in a Calgary winter that means the weight of a trough full of ice. Rotten or split fascia won't hold a fastener, so gutters pull away, water runs behind, and the rot accelerates. Replacing fascia is straightforward while the gutters are off — which is why it's worth doing at the same time as an eavestrough or roof job rather than as its own trip.
Aluminum soffit dents and punctures. Vinyl soffit cracks, particularly when it's cold — Alberta hail in a cold-air storm hits brittle vinyl and breaks it outright. Wind lifts soffit panels out of their channel entirely, which usually shows up as a panel hanging down after a storm. All of it is claimable, and all of it needs to be photographed from underneath to make it into the scope.
Look for frost or dark staining on the underside of the roof sheathing in winter, ice dams at the eave, an attic that's brutally hot in summer, or shingles that failed well before their rated life with no storm involved. Any of those means the system isn't moving air.
That's a very common sequence and it's usually the same cause: blown-in insulation pushed out over the soffit vents, blocking the intake. Baffles hold the insulation back and keep the air path open. It's an inexpensive fix compared with the damage it prevents.
Sectional repair is normal where damage is localised — a few punctured panels or one rotten fascia run. Where it becomes a replacement is when the material is at end of life across the property, or when the colour can't be matched. Matching aluminum on a twenty-year-old house is genuinely difficult and worth knowing before you commit to a patch.
Yes, and it's usually left out. It's covered, it's real, and it's the item most likely to be missed because nobody looked up. If the storm was strong enough to mark your roof, check the soffit.
