The Hidden Costs of Spray Foam: Insurance and Valuation Issues
Table of Contents
Insurance Policy Impacts
Critical Insurance Alert
85% of major UK insurers are now implementing spray foam exclusions or premium increases. This affects both new policies and renewals.
The insurance industry's response to spray foam insulation has been swift and severe. What started as isolated concerns has evolved into widespread policy exclusions that are catching homeowners off guard at renewal time.
Types of Insurance Affected
Home Insurance
Complete exclusions for spray foam related damage
Buildings Insurance
Structural damage limitations and exclusions
Liability Coverage
Professional liability exclusions for installers
Common Policy Exclusions Include:
-
Roof Structure Damage: Damage to rafters, joists, or roof timbers caused by spray foam adhesion or removal
-
Moisture-Related Issues: Condensation, mold, or rot caused by reduced roof ventilation
-
Removal Costs: Professional removal expenses and subsequent repairs
-
Consequential Losses: Secondary damage from initial spray foam problems
Property Valuation Effects
The impact on property values has been devastating for many homeowners. RICS-qualified surveyors are now flagging spray foam as a significant risk factor, leading to reduced valuations that affect both sales and remortgaging opportunities.
Minor Impact
5-10%
Properties with limited spray foam application and no visible issues
Moderate Impact
15-25%
Extensive spray foam with accessibility concerns but no structural damage
Severe Impact
30-50%
Properties with structural damage, moisture issues, or complete roof coverage
