How Fire and Water Shape Mass Timber Claims and Construction
Monday, January 5th, 2026 Education & Training Insurance Industry Property Risk Management TechnologyThe expanding mass timber construction market, projected to reach $1.5 billion by 2031, presents new challenges for the insurance industry—especially for claims adjusters facing increasing loss events tied to fire and water damage. Mass timber’s environmental benefits and design appeal have led to over 2,500 active projects in 2025, but its unique material vulnerabilities demand equally specialized prevention and mitigation strategies.
This article provides a deep dive into how water exposure has overtaken fire as the leading source of claims in mass timber builds, often occurring during early construction phases before full fire protection and weatherproofing are in place. It outlines essential risk control measures, such as assigning site-specific fire and moisture managers, deploying hot and wet works permitting, and applying coatings or technology for early detection and response.
For adjusters, the implications are clear: understanding the construction timeline, the installed safeguards, and any deviation from mass timber-specific best practices can clarify liability and repairability. The industry’s push for more insurability through the Mass Timber Insurance Action Plan (MTIAP) also reflects a growing effort to collect relevant data, define contractor qualifications, and boost capacity. These pilots—including proposals for scenario-based testing facilities—could eventually transform how losses are underwritten and resolved.
In the field, adjusters will need to become increasingly fluent in mass timber systems and how deviations from best practices—especially regarding fire barriers and moisture control—can affect structural integrity and claim valuation. The evolving research and insurer-backed initiatives offer a roadmap to reduce uncertainty and improve claim outcomes on these complex and emerging projects.
