AIA Contract Insurance Requirements for Roofers
Understanding AIA Contract Documents
The American Institute of Architects publishes standardized construction contract documents used on the majority of commercial projects nationwide. The A201 General Conditions and A401 Subcontractor Agreement are the most relevant for roofing contractors. These documents contain detailed insurance provisions in Article 11 that specify what coverages each party must carry, who must be named as additional insured, and how certificates must be delivered. Understanding these provisions before signing is critical because they create binding obligations your insurance program must satisfy.
Required Insurance Coverage Types
Standard AIA contracts require roofing subcontractors to carry commercial general liability (CGL) including products-completed operations, workers compensation at statutory limits, employer's liability, commercial auto liability, and often umbrella or excess liability. Many projects also require builders risk coverage, though this is typically carried by the owner or GC. Professional liability may be required if the roofer provides any design services. Each coverage must be maintained from contract execution through final completion and, for completed operations, for a specified tail period.
Minimum Limits in AIA Contracts
While AIA documents allow parties to fill in specific limits, industry norms on commercial roofing projects call for $1 million per occurrence and $2 million aggregate for general liability, $1 million for auto liability, and umbrella coverage of $5 million to $10 million depending on project size. Workers compensation must meet statutory requirements with employer's liability of at least $1 million per accident. These limits are negotiable, but attempting to reduce them below industry standards signals financial weakness and may cost you the contract.
Additional Insured and Indemnification Clauses
AIA contracts require the subcontractor to name the owner, architect, and general contractor as additional insureds on the CGL policy. This is accomplished through endorsements such as CG 20 10 and CG 20 37, which provide additional insured status for ongoing and completed operations respectively. The indemnification clause in AIA documents typically requires the subcontractor to hold harmless the owner and GC for claims arising from the sub's work. Your insurance must align with these indemnification obligations or you face uninsured exposure.
Negotiating Insurance Terms in AIA Contracts
Not every insurance requirement in an AIA contract is non-negotiable. If a project requires limits exceeding your current program, discuss options with your broker before declining the job. Umbrella limits can often be increased project-specifically. Waivers of subrogation, while standard, should be reviewed with your carrier to ensure they are permitted under your policy. Push back on requirements for coverages that do not apply to your scope, such as professional liability if you provide no design services. Get your agent involved early in the bid process to price insurance costs accurately into your proposal.
