Living in Denver, we’re no strangers to severe weather patterns that can leave our homes vulnerable to nature’s fury. As a structural engineer with over 15 years of experience, I’ve witnessed firsthand how seemingly minor storm damage can escalate into major structural concerns when left unaddressed. The moments following a severe weather event are critical for homeowners—knowing how to properly assess damage and when to seek professional help can mean the difference between a straightforward insurance claim and costly, extensive repairs.
Structural storm damage assessment is not just about identifying visible destruction; it’s about understanding the hidden compromises to your home’s integrity that could threaten your family’s safety. This comprehensive guide will walk you through the essential steps for evaluating storm damage, recognizing when professional intervention is necessary, and navigating the insurance process to protect your most valuable investment.
Understanding Different Types of Storm Damage
Wind Damage: The Invisible Threat
High winds pose unique challenges to structural integrity that often go unnoticed by untrained eyes. While missing shingles or damaged siding are obvious signs, the real concern lies in how wind forces affect your home’s load-bearing systems.
What to look for:
- Roof decking that appears to be lifting or sagging
- Doors and windows that no longer close properly
- Cracks around door frames and window headers
- Separation between walls and ceilings/floors
- Visible movement in roof trusses or rafters
Wind creates both positive and negative pressure on structures, potentially compromising connections between building components. Our Residential Structural Engineering Services in Denver include specialized wind damage assessments that identify these subtle but dangerous issues.
Water and Flood Damage: The Silent Destroyer
Water infiltration from storms can cause both immediate and long-term structural problems. The severity depends on the water source (rainwater, floodwater, or sewer backup) and the duration of exposure.
Critical areas to inspect:
- Foundation walls for new cracking or bowing
- Basement floors for heaving or settlement
- Wood framing for signs of swelling, warping, or rot
- Concrete and masonry for efflorescence (white powder deposits)
- Soil erosion around foundations that compromises support
Floodwaters particularly threaten foundation stability, as documented in our guide on Denver home foundation issues. When saturated soils dry unevenly, they can cause differential settlement that requires immediate attention.
Hail Impact Damage: More Than Cosmetic
While hail primarily affects roofing and exterior surfaces, large hailstones can compromise structural elements through repeated impact on vulnerable areas.
Structural concerns from hail:
- Cracked or compromised roof decking
- Damaged roof supports from large hail impacts
- Weakened structural connections
- Compromised waterproofing leading to future water intrusion
Immediate Post-Storm Safety Assessment
Before conducting a detailed inspection, ensure the property is safe to enter. Follow this safety checklist:
- Check for visible structural hazards – leaning walls, collapsed roofs, or fallen trees on structures
- Assess electrical hazards – watch for downed power lines and avoid standing water near electrical systems
- Evaluate gas line safety – if you smell gas, evacuate immediately and contact utility companies
- Look for chemical hazards – spilled fuels, pesticides, or other hazardous materials
- Document safely – take photographs from multiple angles before approaching damaged areas
Table: Storm Damage Severity Assessment Guide
Damage Type | Minor (Monitor) | Moderate (Professional Assessment Recommended) | Severe (Immediate Professional Intervention Required) |
Roof Damage | Few missing shingles | Multiple missing shingles, sagging areas | Large sections missing, visible structural deformation |
Foundation Cracks | Hairline cracks <1/8″ | Cracks 1/8″-1/4″ wide | Cracks >1/4″ wide, horizontal cracks, bowing walls |
Water Intrusion | Minor dampness in basement | Standing water <1″ deep | Standing water >1″ deep, electrical systems affected |
Window/Door Damage | Single window broken | Multiple units damaged, frames compromised | Structural openings distorted, load-bearing walls affected |
Tree Impact | Small branches on roof | Large branches on structure | Tree trunk on roof or walls, structural penetration |
The Professional Structural Damage Assessment Process

When you hire a structural engineer for a post-storm structural inspection, here’s what to expect:
1. Comprehensive Documentation
We begin with thorough photographic documentation of all visible damage, both interior and exterior. This creates a baseline record for insurance purposes and future reference.
