What to check after a storm
- Panels that have lifted, unlocked or disappeared
- Cracks, holes or broken corners
- Loose outside corners, J-channel or trim around openings
- Sections that bow or move differently than neighbouring courses
- Exposed house wrap, sheathing or insulation
- New interior staining near affected walls or windows
Do not treat every loose panel as cosmetic
Siding sheds water as part of an exterior wall system. A panel that has come loose may be the visible symptom, but the repair should also look at fastening, clearances, trim and the water-management details around the damaged area.
Repair or replacement after storm damage
| Situation | Likely direction |
|---|---|
| A few intact panels have unlocked | A localized repair may be possible after the fastening and locking edges are checked. |
| Several panels are cracked or missing | Broader repair may be needed, especially if matching material is unavailable. |
| Damage repeats across one elevation | That wall may warrant partial or full replacement rather than repeated spot repairs. |
| House wrap or sheathing is exposed | Protect and inspect the wall assembly before new siding closes it back in. |
Document the condition before work starts
Wide photos and close-ups can help show what changed after a storm. If you may make an insurance claim, keep the documentation you need before damaged material is removed.

Questions about Storm-Damaged Siding
Can loose siding be snapped back in after a storm?
Sometimes. The locking edge, fastener slots and surrounding courses should be checked first. A panel that repeatedly comes loose may have an installation or substrate problem.
Should I replace one wall or the whole house?
It depends on the extent of damage, the condition of the other elevations and whether the existing siding can be matched. A damaged elevation can sometimes be handled separately.
