Why don’t insurance companies like spray foam? This is a common question for building owners and facility managers who are evaluating insulation and roofing options for commercial properties. While spray foam can improve insulation, it can also create long-term challenges that impact maintenance, inspections, and overall roof performance.

For commercial properties, understanding these risks is critical before making a decision.

Moisture Retention Risks

One of the biggest concerns with spray foam is its ability to trap moisture within a roofing system.

Over time, this can lead to corrosion, mold growth, and structural deterioration.

Water can become trapped inside the assembly
Moisture may not be visible on the surface
Damage can spread without detection

Hidden Structural Issues

Spray foam is often applied to the underside of roofing systems, which can conceal problems.

Leaks
Seam failures
Substrate deterioration

Inspection Challenges

Commercial roofing systems are designed to be inspected regularly. Spray foam makes this process more complicated.

This can impact how insurance providers assess risk and long-term performance.

Surface conditions are harder to evaluate
Problem areas may not be visible
Maintenance becomes less proactive

More Complex Repairs

When issues occur, repairs can be more difficult.

Remove sections of foam
Locate the source of the problem
Restore both the foam and roofing system

Impact on Long-Term Performance

Spray foam can also affect ventilation and airflow if not applied correctly.

These factors contribute to why insurance companies may view spray foam as a higher risk option.

Heat buildup
Moisture accumulation
Reduced system lifespan

Preferred Roofing Systems

Many commercial roofing systems are designed for visibility and long-term maintenance.

TPO roofing systems
EPDM roofing systems
Commercial Metal or Flat Roof Coatings

Final Thoughts

Why don’t insurance companies like spray foam? Spray foam can trap moisture, hide structural issues, and make inspections more difficult, increasing the risk of undetected damage.
