Why Do Wind Events Cause More Damage to Older Homes?

The short answer

How Age Affects Structural Strength

Older homes were built with materials and methods that were common for their time, but those methods often lack the engineered connections that modern homes use. For example, roof rafters may be nailed to the top wall plate instead of secured with metal hurricane ties. Over decades, wood can dry, shrink, and split, and masonry can develop hairline cracks, all of which reduce the structure's ability to resist wind loads.

Wind events create both pushing and lifting forces. A strong gust can push against a wall, while negative pressure on the roof tries to lift it upward. If the connections between these parts are weak, the whole assembly can fail. This is why you might see an older home lose its roof or have a wall collapse during a windstorm, even if the wind speed is not extreme.

Building Codes Have Changed

Building codes have evolved significantly over the past several decades, with stricter requirements for wind resistance. Many older homes were built before these updates, so they may not have the same level of bracing, anchoring, or impact-resistant windows. Gable end walls, for instance, are often more vulnerable in older construction because they may lack the diagonal bracing that newer codes require.

Even if an older home has been well maintained, it may still be at risk because the original design did not account for today's wind loads. Retrofitting is possible, but it requires a professional assessment to identify weak points. The pros can evaluate the connections and recommend upgrades that meet current standards, though the work depends on the specific home and its condition.

  • Roof-to-wall connections may only be nailed, not tied down
  • Older windows and doors may be less impact-resistant
  • Gable ends often lack proper bracing
  • Foundation anchorage may be minimal or corroded
  • Sheathing may be thinner or not properly nailed
  • Masonry walls may have deteriorated mortar

Deterioration Takes Its Toll

Age brings natural wear and tear. Wood can rot where moisture has seeped in, and termites or other pests may weaken framing members. Metal connectors can corrode, losing their strength. Even if the home looks sound from the outside, hidden damage can make it more vulnerable to wind. A thorough inspection can reveal these issues before a storm hits.

If you live in Fresno, where the climate is hot and dry, wood can dry out and crack over time. That dryness can reduce flexibility, making materials more brittle. While you cannot reverse aging, you can address specific weaknesses. A water damage inspection can help you understand what needs attention, so you can prioritize repairs.

What You Can Do to Reduce Risk

You can take practical steps to reduce wind damage without a full renovation. Start by checking the condition of your roof, especially the edges and gable ends. Look for loose shingles or nails that have popped. Trim overhanging branches that could break and hit your home. Secure loose items in your yard, like patio furniture or trash cans, which can become projectiles.

Inside, confirm that your garage door is reinforced, as it is often a weak point in wind events. If you have an older home, consider having a professional assess the connections between your roof and walls. They can install metal brackets or straps to strengthen these areas. Document any existing damage with photos, as this can help with insurance claims later.

  • Check and replace loose roof shingles or tiles
  • Trim tree branches that hang over your house
  • Secure outdoor furniture and decorations
  • Reinforce your garage door if it is old or flimsy
  • Inspect for cracks in walls or foundation
  • Keep gutters clear to prevent water pooling

When to Call the Pros

After a wind event, even if the damage looks minor, it is wise to have a professional look. Water may have entered through small gaps, leading to hidden moisture problems. A water damage assessment can identify issues like damp insulation or stained drywall. The pros can also document the damage for your insurance claim, though policies vary, and your insurer decides what is covered.

If you notice structural issues, such as a sagging roof or cracked walls, do not wait. Structural repairs after damage require careful work to ensure the home is safe. The pros can stabilize the structure and make necessary repairs, but the process depends on the extent of the damage and the materials involved. Acting quickly can prevent further deterioration.

Frequently asked questions

Can I retrofit my older home to withstand wind better?

Yes, retrofitting is possible. Common upgrades include adding metal ties to connect the roof to the walls, bracing gable ends, and reinforcing garage doors. A professional inspection can identify the most important improvements for your specific home.

Will my insurance cover wind damage to an older home?

Policies vary, and your insurer decides what is covered. Wind damage is often included in standard homeowners policies, but exclusions may apply. Review your policy and document all damage with photos before filing a claim.

How do I know if my home has weak connections?

You can look for signs like gaps between the roof and walls or exposed nails. However, a professional water damage inspection can provide a thorough evaluation, checking hidden areas like attics and crawl spaces for structural weaknesses.
