Why Do High Winds Cause More Damage to Older Homes?

The short answer

Outdated Building Materials and Methods

Many older homes were built with materials like lime mortar, which is softer and more prone to cracking than modern Portland cement. Original wooden framing may have degraded over decades from moisture or insect damage, reducing its strength. These materials were not engineered for the wind loads defined by current building codes, making the entire structure more susceptible to failure when high winds strike.

Roof and Siding Vulnerabilities

Older roofing materials, such as wood shakes or original three-tab asphalt shingles, are more easily torn off by wind. They may be brittle from sun exposure or have fewer fasteners per shingle than modern requirements. Once the roof covering is compromised, wind can enter the attic space, creating internal pressure that can push out walls and cause catastrophic structural damage.

Siding on older homes, like wood clapboard or stucco applied over wood lath, is also prone to failure. High winds can catch loose boards or exploit small cracks in stucco, peeling them away from the wall sheathing. This breach allows wind-driven rain to soak the wall cavity, leading to immediate water damage and creating conditions for mold to develop later.

  • Wood shake roofs can become dry and brittle, lifting easily.
  • Original asphalt shingles may have adhesive strips that have failed.
  • Wind can exploit gaps where siding meets roof eaves or corners.
  • Loose or corroded fasteners on siding provide little resistance.
  • Older stucco may lack a modern drainage plane behind it.
  • Once siding fails, rain soaks insulation and wooden framing.

Window and Door Weak Points

Original windows and doors in older homes are significant weak points. Single-pane glass is more fragile, and the wooden frames holding them may have warped or rotted over time, creating gaps. These openings allow wind pressure to enter the home, which can stress the structure from the inside out. Flying debris from a storm also easily shatters older, thinner glass.

Furthermore, the methods used to secure these units are often insufficient. Doors may be held by short, weak hinges and frame screws. Window frames might be nailed, not bolted, into the rough opening. During high winds, the entire window or door assembly can be pushed inward, creating a large opening that compromises the building's envelope and leads to extensive interior damage.

The Role of Wear and Maintenance

Decades of exposure to weather cycles take a toll on any home. In older properties, this wear is more pronounced. Small, unrepaired issues like cracked caulking, loose soffits, or a few missing shingles become major failure points under high wind stress. A newer home might withstand the same gust, but an older one with cumulative minor damage is more likely to experience a cascading failure.

Regular maintenance can mitigate some risks, but many components in an old house are simply at the end of their service life. Gutters may pull away, taking fascia boards with them. Chimneys with old mortar can topple. Tree limbs may have grown close to the roof. These age-related factors, combined with the force of high winds, explain why older homes often sustain more severe and costly damage.

What to Do After Wind Damage

If high winds damage your older home, your first priority is safety. Stay away from structural hazards like sagging ceilings or cracked walls. If it is safe to do so, mitigate further water intrusion by covering broken windows or holes in the roof with tarps. Document all damage with photos and notes for your insurance company before any cleanup begins.

Contact local water damage pros for a thorough inspection. They can assess hidden moisture in walls and subfloors that leads to mold. For major structural issues, you will also need a qualified general contractor. Policies vary, and your insurer decides what is covered. Be prepared to discuss the specific vulnerabilities of your older home, as restoration may involve bringing some elements up to current code.

  • Ensure the structure is safe before re-entering.
  • Temporarily cover openings to prevent more rain from entering.
  • Take extensive photographs of all damage, inside and out.
  • Contact your insurance provider to start a claim.
  • Have a professional inspect for hidden water and structural issues.
  • Keep records of all repairs and communications.

Frequently asked questions

Can I prevent wind damage to my older home?

You can take preventive steps like installing hurricane clips, reinforcing roof sheathing, and replacing old windows with impact-resistant ones. Regularly inspecting and maintaining your roof, siding, and trim is crucial. However, due to inherent age-related weaknesses, complete prevention may not be possible without significant structural upgrades.

Does home insurance cover wind damage to older homes?

Most standard policies cover sudden wind damage, but you should check your specific policy for exclusions like wear and tear. Insurers may factor in the home's age and condition. Policies vary, and your insurer decides what is covered. Always document pre-existing conditions and storm damage thoroughly.

What is the biggest risk from wind-driven rain?

The greatest risk is hidden water intrusion into wall cavities, attics, and subfloors. This moisture can lead to widespread rot, mold growth, and compromised structural integrity within days. Prompt drying by water damage professionals is essential to prevent these secondary damages, which are often more costly than the initial wind damage.
