Look for obvious signs like loose or missing panels, cracks that go all the way through, or any gaps where you can see the house wrap underneath. These let water in, and water damage gets expensive fast.
After storms, check for dents, warping, or panels that seem to be pulling away from the house. Even small damage can become big problems when the next weather event hits.
If you’re not sure, it’s worth having someone take a look. A quick inspection now can save you from major repairs later.
