Commercial Umbrella Insurance for Residential Roofing Contractors

Key Endorsements for Residential Roofing Commercial Umbrella

A commercial umbrella policy sits above the roofer's GL, auto, and employers liability policies, providing additional limits when underlying coverage is exhausted. For residential roofers facing large bodily injury and property damage exposures, umbrella coverage is not optional — it is contractually required by most GCs and increasingly demanded by homeowners on high-value projects.

UMB 100 — Following Form Umbrella Endorsement

This endorsement confirms the umbrella "follows form" with the underlying GL and auto policies, meaning it adopts the same coverage terms and conditions. For residential roofers, following form is critical because it ensures the umbrella responds to completed operations claims, additional insured obligations, and property damage claims on the same basis as the CGL. A non-following-form umbrella may introduce coverage gaps that leave the roofer exposed above the primary layer.

UMB 200 — Defense Cost Coverage

Some umbrella policies treat defense costs as supplementary (outside the limit), while others include defense costs within the policy limit. This endorsement clarifies the treatment. Residential roofers should insist on defense costs outside the limit, as roofing litigation can generate $50,000-$150,000 in defense expenses alone. If defense erodes the umbrella limit, less money remains for actual settlements.

UMB 310 — Underlying Insurance Requirements

This endorsement specifies the minimum underlying limits the umbrella requires to remain in force. Most umbrella carriers require residential roofers to maintain $1M/$2M GL, $1M auto liability, and $500K/$500K/$500K employers liability underneath. If the roofer reduces any underlying limit, the umbrella may not respond, creating a catastrophic gap.

UMB 450 — Aggregate Reinstatement

If the umbrella's aggregate is exhausted by a claim, this endorsement reinstates the full limit for the remainder of the policy period. For busy residential roofers running multiple crews across many jobsites, aggregate reinstatement prevents a single large claim from eliminating umbrella protection for the rest of the year.

RLI Insurance

RLI is one of the most active umbrella writers for residential roofing contractors. They offer $1M-$5M umbrella limits with competitive pricing for roofers with clean loss history and an EMR under 1.15. RLI's umbrella follows form with most standard GL and auto policies and includes automatic coverage for newly acquired entities. Their key advantage is willingness to write over admitted and non-admitted primary carriers, giving roofers flexibility in their underlying program. RLI requires annual exposure audits and reviews loss runs going back five years.

Markel Specialty

Markel writes umbrella coverage for residential roofers through their contractor specialty division. They are one of few carriers offering $10M umbrella limits for roofing operations, making them a fit for larger companies doing subdivision work or government contracts. Markel's pricing is mid-range, but they impose strict requirements: all underlying policies must be with carriers rated A- VII or better by AM Best, and the roofer must have a written safety program. Markel also requires that the roofer's workers' comp EMR not exceed 1.00 for umbrella limits above $5M.

CNA

CNA's umbrella program targets established residential roofing companies with $2M+ in annual revenue. Their following-form umbrella provides broad coverage including personal and advertising injury, which some competitors exclude. CNA offers a three-year policy option that locks in rates, protecting roofers from premium spikes after isolated claims. The limitation: CNA does not write umbrellas for roofers with any open litigated claims, regardless of merit.

Berkshire Hathaway Guard

Guard offers umbrellas for small residential roofers starting at $1M with premiums as low as $1,200 annually for clean accounts. Their underwriting process is streamlined — often requiring only an application and three years of loss runs. Guard's umbrella is more restrictive than larger carriers, however: it excludes pollution liability, employment practices, and professional liability, meaning it truly only provides excess GL, auto, and employers liability coverage.

$1,450,000 — Catastrophic Fall Injury, Raleigh, NC

A residential roofer's employee fell 24 feet from a steep-pitch roof, landing on concrete. The worker suffered a traumatic brain injury, spinal fractures, and bilateral leg fractures. Workers' compensation covered medical and disability benefits, but the injured worker's spouse filed a third-party negligence suit against the roofing company alleging inadequate fall protection. The GL policy paid its $1M per-occurrence limit. The remaining $450,000 in settlement — including future medical monitoring and loss of consortium — was paid by the $2M commercial umbrella. Without the umbrella, the roofer would have faced $450,000 in personal liability, likely forcing bankruptcy.

$2,100,000 — Multi-Vehicle Highway Accident, Atlanta, GA

A residential roofer's dump truck experienced brake failure on I-285 and rear-ended three vehicles in a chain reaction. Six people sustained injuries ranging from whiplash to herniated discs and a fractured sternum. The commercial auto policy paid its $1M combined single limit. The umbrella policy covered the remaining $1,100,000 in settlements across multiple claimants. Defense costs — handled outside the umbrella limit — totaled $187,000 across four separate lawsuits. The total insured cost exceeded $2.1M, demonstrating why a $1M auto policy alone is grossly insufficient for roofing contractors operating heavy vehicles.

$780,000 — Completed Operations Fire, Scottsdale, AZ

Three months after a residential roofer completed a re-roof, improper installation of a rooftop solar panel flashing caused an electrical arc that ignited the underlayment. The resulting fire destroyed two bedrooms, the master bathroom, and caused smoke damage throughout the 4,200 sq ft home. The homeowner's insurer subrogated against the roofer for $780,000, including structural repairs ($520,000), personal property ($145,000), and additional living expenses ($115,000). The roofer's GL completed operations coverage paid $500,000 (the per-occurrence sub-limit), and the umbrella paid the remaining $280,000. The roofer's GL premium doubled at the next renewal.
