Optimal materials for homemade hail protection?

May 8, 2026

Quick Answer

For homemade hail protection, use sturdy materials like plywood, corrugated metal, or thick plastic sheets to cover windows and doors, and employ a tarp or large piece of canvas to provide a makeshift roof. These materials can withstand golf-ball-sized hail. A combination of these solutions can offer effective protection.

Gathering Materials

When preparing for a hail storm, have a stockpile of essential materials ready. A 4x8 foot plywood sheet is ideal for covering a standard window. For a larger window or an entire door, use 3/4 inch or thicker corrugated metal. If using a tarp or large piece of canvas, secure it with sturdy ropes and weights. Ensure all materials are free of sharp edges and debris.

Creating a Protective Barrier

To set up a makeshift roof, attach the tarp or canvas to the roof’s existing structure using clips or weights. For added protection, place a layer of plywood or corrugated metal underneath the tarp to distribute hail impact and reduce damage. When covering windows and doors, use a combination of screws, nails, and tape to secure the materials firmly in place. A minimum of 1 inch overlap between each piece is essential to prevent gaps.

Additional Considerations

To enhance hail protection, consider adding a layer of foam board or thick cardboard to the plywood or corrugated metal for added cushioning. Also, store essential items like flashlights, first aid kits, and battery-powered radios in a safe area to ensure accessibility during the storm. Always prioritize your safety and the safety of others when dealing with severe weather conditions.
