After wind, hail, or heavy rain, the first job is stopping more water from getting in. That means a tarp over the opening in the roof, boards over broken windows or doors, and extraction of whatever has already come inside. Each step limits the loss, and most policies expect you to take reasonable steps to prevent further damage.
Photograph the damage before anything is moved, keep the receipts, and call your insurer. Heartland records moisture readings and photos as the work goes, so the scope you hand your adjuster is documented rather than remembered. The company bills homeowners insurance directly.
Storm water that reached the inside as rain through a damaged roof is not the same as a creek overflowing, and the difference matters for coverage. The linked answer on water damage versus flood damage explains how insurers draw that line.
