Because of long term climate change, the variable weather is increasing in intensity which could damage buildings. There are of numbers solutions to harden the structure to brace against hurricanes, tornados, storm winds carrying debris like small missiles into your structure.
Like any standard window, frame construction on a hurricane-resistant, storm-proof window can use aluminum or steel, vinyl, or wood. Aluminum or steel frames are considered the strongest (and most expensive), but there is some maintenance associated with these. Vinyl-framed windows are a great cost-effective solution with good insulation value, but at the end of their life, recycling the materials can be difficult. Wood frames offer good insulating value, but because they need to be regularly painted, the cost of maintenance is highest among the three frame options. And over time, wood windows can be susceptible to warping. There are also several glass options when it comes to hurricane-resistant, storm-proof windows. The different glazing types are identified by the laminate procedure by which the glass panes are joined with the interlayer.
For protection from tornados and rapidly spreading wildfires, above-ground interior shelters need to offer the ultimate in multi-purpose protection and security. Shelters must withstand the most extreme tornado activity and offer a safe zone against home invasion.

Metal roofing is generally considered the best option for hurricane, tornado and fire resistance. Most metal varieties come with a warranty, offering defense against winds up to 140 mph. Metal roofs can be installed over your existing roof without tearing off shingles, provided local building codes allow it.
