Installation Floater Insurance for Residential Roofing Contractors

Key Endorsements for Residential Roofing Installation Floater

An installation floater protects materials and equipment during the installation process — from the moment materials arrive at a jobsite through the point of completed installation. For residential roofers, this fills the gap between inland marine (transit and storage) and the homeowner's property insurance (post-completion). The standard ISO Installation Floater Form (IM 00 01) provides the framework.

IM 00 15 — Materials in Transit Extension

This endorsement extends the installation floater's coverage backward to include materials while they are being transported to the jobsite. For residential roofers who pick up shingles, underlayment, and flashing from supply houses and transport them in company trucks, this endorsement eliminates the coverage gap between the supply house's care and arrival at the homeowner's property. Without it, materials damaged in a truck accident may fall between the inland marine and installation floater policies.

IM 00 20 — Existing Structure Coverage

When residential roofers perform tear-offs and re-roofs, they temporarily expose the homeowner's existing structure to weather and damage. This endorsement covers damage to the existing structure caused by the roofing work. If a crew removes an old roof and a surprise rain damages interior ceilings, walls, and flooring before the new roof is installed, this endorsement responds. It is arguably the most important endorsement for residential re-roofing operations.

IM 00 30 — Delay in Completion

If covered property damage delays the roofing project — for example, a fire destroys installed materials and the job must restart — this endorsement covers the roofer's additional costs, including extended equipment rental, rescheduling fees, and penalty clauses in the contract. Residential roofers working under tight timelines from insurance restoration contracts benefit from this protection.

IM 00 25 — Testing and Startup

For roofers installing integrated systems like solar-ready roofs or rooftop HVAC platforms, this endorsement covers damage during the testing and commissioning phase after installation is mechanically complete but before the homeowner accepts the work.

Zurich Construction

Zurich offers installation floaters tailored for residential roofing contractors through their construction specialty division. Their product covers materials, labor, and equipment during installation with limits up to $500,000 per project. Zurich's standout feature is their blanket installation floater — rather than issuing a separate floater for each job, roofers get a single annual policy covering all projects up to a per-project cap. This eliminates the administrative burden of reporting each residential job individually. Zurich requires detailed job logs and reserves the right to audit project values quarterly.

Travelers Construction

Travelers' installation floater for residential roofers includes built-in existing structure coverage up to $100,000 per occurrence — a valuable inclusion that many competitors charge extra for. Their policy is occurrence-based with no coinsurance penalty, which means roofers don't face reduced payouts for underreporting project values. Travelers requires roofers to maintain a minimum $1M GL policy as a condition of the installation floater, and they coordinate the two coverages to avoid overlap and gaps. Their deductibles range from $1,000 to $5,000 depending on the roofer's loss history.

Nationwide Construction

Nationwide targets smaller residential roofers with installation floaters starting at project values of $25,000. Their product is straightforward, covering materials and labor from delivery through installation. Nationwide's limitation is their weather-damage exclusion — their standard form excludes damage from wind, hail, or rain to materials not yet incorporated into the structure. Roofers must purchase an endorsement to remove this exclusion, which adds 15-20% to the premium.

Berkley Construction Solutions

W.R. Berkley's construction arm writes installation floaters for residential roofers with project-specific or annual options. Their annual floater allows unlimited projects up to $250,000 each. Berkley's key differentiator is their "soft costs" coverage, which includes architect and engineering fees, permit re-filing costs, and contract penalty reimbursement when covered damage delays the roofing project. This is particularly valuable for roofers working on insurance restoration jobs where deadlines are contractual obligations.

$78,000 — Rain Damage During Tear-Off, Memphis, TN

A residential roofing crew completed a full tear-off on a 2,800 sq ft home and installed synthetic underlayment before quitting for the day. Overnight, 3.5 inches of rain fell, and water infiltrated through gaps in the underlayment at the valleys and penetrations. The homeowner's hardwood floors, kitchen ceiling, and master bedroom drywall sustained significant water damage. Interior repairs totaled $54,000, and the roofer faced $24,000 in additional costs including mold remediation and temporary housing for the homeowner. The installation floater with existing structure coverage paid the full claim after a $2,500 deductible, protecting the roofer from a devastating out-of-pocket loss.

$34,000 — Material Theft During Installation, San Antonio, TX

A residential roofer staged $28,000 in standing-seam metal roofing panels at a jobsite over the weekend ahead of a Monday installation. By Sunday morning, all panels were stolen from the homeowner's driveway. The roofer also lost $6,000 in fasteners, sealants, and trim pieces stored on-site. The installation floater covered the full $34,000 in material replacement, and the carrier expedited the claim, issuing payment within 12 business days. The roofer was able to reorder and install the roof with only a 10-day delay, avoiding contract penalties.

$145,000 — Fire During Hot-Torch Application, Chicago, IL

While applying modified bitumen roofing on a flat section of a residential addition, a roofer's torch ignited the substrate and existing wall sheathing. The fire spread into the attic space before the crew could extinguish it. Damage to the existing structure — including roof trusses, attic insulation, electrical wiring, and two upstairs rooms — totaled $118,000. The roofing materials already installed and destroyed in the fire were valued at $15,000. Equipment damage added $12,000. The installation floater's existing structure endorsement covered $118,000 in structural damage, while the material and equipment losses were covered under the base floater. Total payout was $145,000.
