Installation Floater Insurance for Commercial Roofing Contractors

Installation Floater Coverage Form (Inland Marine)

The installation floater is a specialized inland marine form that covers materials, equipment, and supplies you have been contracted to install from the moment you take possession through completed installation. For roofing contractors, this means coverage for TPO membrane rolls, metal panels, insulation boards, fasteners, flashing, and all other roofing components from the supplier's dock through final inspection. This fills a critical gap — the supplier's coverage ends at delivery, your GL covers liability but not your own materials, and the building owner's policy may not cover materials not yet installed.

Transit Coverage Extension

Extends installation floater coverage to materials in transit between the supplier, your warehouse, and the jobsite. For roofing contractors transporting large quantities of expensive materials — a single load of standing seam copper panels can exceed $150,000 — transit losses from accidents, theft, or weather damage represent significant financial exposure. This extension covers the full value during transport regardless of who is driving.

Delayed Completion / Soft Costs Extension

When covered materials are damaged or destroyed, this extension reimburses the additional costs incurred due to project delays — expedited shipping for replacement materials, extended equipment rental, and overtime labor to meet the original deadline. Commercial roofing contracts frequently include liquidated damages clauses of $500-$2,000 per day for late completion, making this extension financially critical.

Testing and Commissioning Coverage

Covers damage to installed roofing systems during flood testing, infrared scanning, or other quality assurance procedures. Flat roof installations on commercial buildings routinely undergo flood testing to verify waterproofing integrity. If the test reveals a failure that causes water damage to the building interior, this coverage responds to the resulting property damage.

Hartford

Hartford offers one of the most comprehensive installation floater programs for roofing contractors. Their form covers materials at replacement cost with no coinsurance penalty, which benefits roofers who may underestimate project material values. Hartford's transit sublimit is generous at $500,000 per conveyance, adequate for most commercial roofing loads. They include automatic coverage for materials stored at the contractor's premises up to 30 days before installation without additional premium.

Acuity

Acuity bundles installation floater coverage into their contractor package policies at no additional premium for roofing contractors with annual material values under $1M. This integration simplifies administration and ensures no coverage gaps between GL and inland marine. Acuity's installation floater covers materials at the jobsite, in transit, and at temporary storage locations. Their per-project limit is typically $250,000, which may need to be increased for large commercial roofing projects.

Travelers

Travelers writes standalone installation floater policies for roofing contractors handling high-value projects. Their program supports per-project limits up to $25M and includes broader perils coverage than most competitors — including earthquake and flood for materials on-site. Travelers also offers a reporting-form installation floater where the contractor reports each project's material value as work begins, paying premium only on active projects. This is cost-effective for contractors with variable project volumes.

Great American

Great American's installation floater program for roofing contractors includes a unique feature — coverage for materials that fail during the warranty period due to manufacturing defects, not just installation errors. This is valuable for roofers who provide extended warranties on commercial roofing systems. Their pricing is mid-market, and they require itemized material lists for projects exceeding $500,000 in installation value. Great American's claims process includes direct-repair options with roofing material suppliers, expediting replacement.

$165,000 — Vandalism to Stored Materials, Detroit, MI

A roofing contractor staged $165,000 worth of single-ply PVC membrane and rigid insulation boards on the ground level of a commercial construction site over a weekend. Vandals slashed the membrane rolls and scattered insulation boards across the muddy lot, rendering them unusable. The installation floater covered the full replacement cost of the destroyed materials. The contractor added the cost of temporary fencing and security cameras to future project bids. The claim was paid within three weeks, allowing the project to resume with minimal schedule impact after replacement materials were sourced.

$88,000 — Rain Damage to Insulation, Portland, OR

Rigid polyiso insulation boards were delivered to a commercial roofing project and stored on the roof awaiting installation. An unexpected rainstorm saturated the boards before the crew could cover them with tarps. Wet polyiso insulation loses its R-value permanently and cannot be dried and reused. The installation floater paid $88,000 for replacement insulation at current material prices, which had increased 12% since the original purchase. The delayed completion extension covered an additional $15,000 in expedited shipping costs to meet the project deadline.

$312,000 — Truck Accident Destroys Custom Metal Panels, Austin, TX

A tractor-trailer carrying custom-fabricated architectural metal roof panels for a high-end commercial project jackknifed on a wet highway, scattering panels across the roadway. The panels were custom-colored with a unique profile and had a 10-week fabrication lead time. The installation floater's transit coverage paid $312,000 for the destroyed panels and covered $28,000 in expedited re-fabrication charges. The soft costs extension paid $44,000 in liquidated damages the contractor owed the building owner for the resulting project delay, bringing the total claim to $384,000.
