1. Temporary Roof Repairs
Prioritize a temporary roof repair that lasts at least six months, allowing time for careful assessment and avoiding inflated repair costs. To weatherproof, drape large tarps over the roof ridge, securing them tightly at the edges. Use heavy-duty tarps from agricultural supply stores. For missing roof sheathing, patch with exterior-grade plywood of the same thickness.

2. Replacement for Missing Roof Material
If the outer roof material is absent, use 30- to 90-pound asphalt-impregnated roofing felt. Nail it along seams every 6 inches using felting nails. The 90-pound felt can last up to two years. When using 90-pound roll roofing with a mineral face, install it with the mineral side against the sheathing. Heavy felt is a suitable base for fiberglass shingle roofs, but remember to remove it for tin roofs.

3. Repair and Secure Gutters and Downspouts
Wire or secure loose or damaged gutters and downspouts to effectively redirect water away from the house.

4. Tree Removal for Safety
Before commencing repairs, remove trees from the house to ensure safety and accessibility.

5. Preserve Architectural Fragments
Keep and safeguard architectural fragments and building materials, even if they don't belong to your house. They could prove valuable for restoration efforts.

6. Address Water-Damaged Wood Floors
Treat water-exposed wood floors by washing them with fresh water. Absorb any saltwater using paper towels (avoid newspapers to prevent ink stains). Warping may occur as the floors dry, so avoid forced drying methods like heating or air conditioning. Patience is key, as it might take months for floors to be ready for refinishing.

7. Deal with Damp Interior Wall Insulation
If interior wall insulation is damp, remove it through the baseboard. Allow the interior wall to thoroughly dry. Combat mold and mildew by scrubbing walls with a weak solution of Clorox bleach and water.

8. Manage Loose Plaster
Inspect for loose plaster and either secure it in place with screws or remove it. Save any decorative plaster pieces that have fallen for potential restoration.
