SPF Rig & Equipment Insurance for SPF Contractors
Your SPF proportioner is your production asset — typically $20,000 to $80,000+ in replacement value — and it is not covered under your commercial auto policy. Inland marine rig insurance (equipment floater) covers your proportioner, heated hose assemblies, spray guns, and ancillary equipment on-site, in-transit, and at your yard or shop.

What it covers
- Proportioner machine (agreed-value or replacement-cost basis) — $15,000 to $80,000+
- Heated hose assemblies including heated transfer hoses
- Spray guns, tip kits, and application equipment
- Drum heaters and auxiliary heating equipment
- Generators and power equipment used for SPF operations
- Equipment in transit between job sites
- Equipment at temporary job-site storage locations
- Equipment at your shop or yard location
Who it's for
- Any SPF contractor with a proportioner machine (open-cell or closed-cell)
- Contractors who assumed proportioner equipment is covered under commercial auto
- SPF roofing contractors with high-output proportioner equipment ($50,000+)
- Contractors with multiple proportioners or spare hose assemblies
- SPF contractors who finance their proportioner and require lender certificate of insurance
Why CCA
- Agreed-value endorsements — we write proportioners at agreed value, not ACV, eliminating depreciation disputes at claims time
- Replacement-cost coverage — new proportioner replacement including installation and startup
- Equipment inventory review — we ensure heated hoses, spray guns, and ancillaries are scheduled
- Lender certificate issuance — we add equipment lenders as loss payees for financed proportioners
- Coordination with commercial auto — we document the boundary between auto and equipment coverage to prevent gaps
Common questions about spf rig & equipment insurance
An inland marine policy (equipment floater) covers mobile equipment at whatever location it's used — job sites, in transit, and at your yard. It fills the gap left by commercial auto (covers the vehicle, not the equipment) and commercial property (covers fixed-location property, not mobile equipment).
Agreed value is preferable for proportioners. At ACV, depreciation is applied at claims time — a 5-year-old proportioner might pay out at 50% of replacement cost. At agreed value, the policy pays the agreed amount regardless of depreciation. We write proportioner floaters at agreed value wherever markets allow.
Yes, when properly scheduled. Heated hose assemblies — which can run $3,000 to $8,000 per set — must be listed on the equipment schedule. We review your full equipment list to ensure hoses, spray guns, and ancillaries are included in the floater.
Yes. SPF-specific GL is endorsed to cover isocyanate exposure events and off-ratio application claims that standard GL pollution exclusions and product exclusions eliminate. A standard contractor GL policy will typically deny SPF-related claims.
In most cases, yes. GL covers general bodily injury and property damage from your operations. CPL specifically covers pollutant-triggered claims — isocyanate and VOC exposure events that fall under GL pollution exclusions. The two policies work together to provide complete coverage for SPF applicators.
Yes. We write SPF contractor insurance in all 50 states through admitted and E&S carriers. Some states have more SPF carrier options than others — California, Texas, and Florida have the deepest SPF markets.
A.M. Best assigns financial strength ratings to insurance carriers. A-rated carriers have demonstrated strong financial strength and are required by most commercial contracts. We place SPF insurance exclusively through A-rated and A+ A.M. Best rated carriers.
Yes. SPF GL policies can add general contractors, property owners, and project managers as additional insureds. We process certificate requests and additional insured endorsements same-day.
Annual review is standard, but coverage should also be reviewed when: you add application types (e.g., start doing SPF roofing), add crew members, purchase new proportioner equipment, expand to new states, or take on commercial projects with higher limit requirements.
Occurrence-based GL covers claims for events that occur during the policy period regardless of when the claim is filed. Claims-made GL covers claims filed during the policy period. For SPF contractors with completed-operations exposure (foam applied in prior years), occurrence-based GL is generally preferable — it covers long-tail completed-operations claims without requiring tail coverage.
Tail coverage (extended reporting period) applies to claims-made policies. It extends the period during which claims can be reported after the policy ends. If you hold a claims-made GL or CPL, tail coverage is critical when you cancel or change carriers — especially for SPF applicators with completed-operations exposure from prior years.
SPF-specific GL includes completed-operations coverage for claims arising from foam applied in prior policy periods. Standard GL completed-operations exclusions for SPF work are common — verify your policy covers SPF completed operations explicitly.
Yes. New SPF contractors without prior insurance history can be placed in E&S markets with slightly higher rates, with rates typically improving after 1–3 years of clean loss history. We work with markets that write new-venture SPF accounts.
Most SPF contractors carry $1M per occurrence / $2M aggregate. Commercial projects and GC requirements frequently call for $2M/$4M or $3M/$6M. Umbrella policies are then stacked above to reach $5M or $10M total limits.
Report claims to your carrier immediately upon a covered event or notice of potential claim. For SPF contractors, this includes: off-ratio application events, occupant complaints about off-gassing, foam adhesion failures, and any third-party bodily injury or property damage arising from your SPF work. We provide claims coordination and carrier contact guidance.
Yes — and we recommend it. Coordinating GL, CPL, WC, commercial auto, rig insurance, and umbrella through a single agency prevents coverage gaps (particularly between commercial auto and rig equipment), simplifies certificate management, and allows us to review the full program for completeness annually.
An equipment floater (inland marine) covers mobile equipment — like your SPF proportioner — wherever it goes: job sites, in transit, and at your yard. Commercial property only covers equipment at a fixed, scheduled location. SPF proportioners require a floater, not a property policy, because they move with every job.
