Interactive coverage guide

Build a coverage stack around how the business actually operates.

Start with the preselected industry or trade, then adjust the operational questions. The commonly considered stack updates live. Keep the coverages you want GIB to evaluate, remove ones you do not want included in your quote request, and add other available lines before continuing.

Common Starting Coverages

General LiabilityThird-party injury and property damage

What it is

General Liability commonly addresses covered third-party bodily injury, property damage and certain personal or advertising injury claims, subject to the policy.

Why businesses like yours commonly carry it

Businesses commonly use it as a starting liability policy and to satisfy customer, landlord or contract requirements.

Possible coverage gap

General Liability is not intended to replace policies for employee injuries, business vehicles, owned property, cyber events or professional errors.

Business Owners Policy / Commercial PackageLiability and property components evaluated together

What it is

A Business Owners Policy commonly combines liability and property coverages for eligible businesses. A Commercial Package Policy may combine multiple commercial coverage parts depending on the account and carrier.

Why businesses like yours commonly carry it

Businesses with premises, contents, inventory or other property exposures may ask GIB to evaluate whether liability and property components can be packaged where appropriate.

Possible coverage gap

Eligibility, included coverages and package structure vary by carrier. Commercial Property may also be written separately rather than as part of a package.

Commonly Added Based on Operations

Commercial AutoBusiness vehicles, drivers and physical damage

What it is

Commercial Auto may address liability arising from covered business vehicles and, when selected, physical damage and other vehicle-related coverages.

Why businesses like yours commonly carry it

Businesses that own or regularly use vehicles may need a policy structured around business use, drivers and vehicle schedules.

Possible coverage gap

Personal auto policies may restrict or exclude business use, and General Liability is generally not a substitute for auto liability.

Cyber Liability & Data BreachCyber events, data and system interruption

What it is

Cyber insurance may address certain first-party and third-party losses from covered data breaches, cyberattacks, ransomware and system interruption, depending on the policy.

Why businesses like yours commonly carry it

Suppliers invoice contractors constantly and are among the businesses most often impersonated in payment-change fraud.

Possible coverage gap

General Liability generally should not be assumed to address data breach response, ransomware or network interruption.

Exposure-Dependent Coverages

Equipment BreakdownMechanical, electrical and pressure-system breakdown

What it is

Equipment Breakdown may address certain sudden mechanical, electrical or pressure-system breakdown losses, subject to the policy.

Why businesses like yours commonly carry it

Businesses dependent on refrigeration, production, HVAC, electrical or other critical equipment commonly consider it.

Possible coverage gap

Standard property forms may not address every internal mechanical or electrical breakdown.

Learn more about Equipment Breakdown
Commercial Crime / FidelityEmployee theft and certain fraud losses

What it is

Commercial Crime may address certain covered theft, fraud and funds-transfer losses, depending on the selected insuring agreements.

Why businesses like yours commonly carry it

Businesses handling money, inventory, payments or account access commonly consider crime coverage.

Possible coverage gap

Property and cyber policies do not necessarily cover every employee theft or social-engineering loss.

Learn more about Commercial Crime / Fidelity
Umbrella / Excess LiabilityAdditional limits above scheduled liability policies

What it is

Umbrella or Excess Liability may provide additional limits above identified underlying liability policies, subject to its own terms and exclusions.

Why businesses like yours commonly carry it

Businesses with larger contracts, vehicles, public exposure or higher severity potential commonly consider additional limits.

Possible coverage gap

An umbrella does not automatically broaden every exclusion or sit over every policy unless the issued terms say it does.

Property and Fire

Large combustible stock, outdoor storage, sprinklers and wildfire exposure drive property underwriting.

Product Allegations

A supplier can be named when a roof leaks even if installation or design caused the loss.

Middle-Market Account Profile

For a middle-market roofing distributor, the underwriting file should quantify membrane versus shingle revenue, combustible insulation, coatings/adhesives, rooftop-delivery percentage, boom-truck use, maximum outdoor stock, seasonal inventory swings, top manufacturers and whether any material is private labeled or imported.

Coverage Priorities for This Niche

The strongest program coordinates warehouse/yard property with products liability, delivery auto, cargo, workers compensation and excess. Where coatings, adhesives or fuels are material, pollution should be evaluated. Cyber and crime also matter because ordering, contractor accounts and vendor payment instructions increasingly move through ERP and email.

Underwriting Questions Before Marketing the Account

Questions worth reviewing before marketing or binding this account:

How much product is stored outdoors at peak season?
What percentage of deliveries are rooftop or boom-assisted?
Does the company private label or import any roofing products?
Which manufacturers provide contractual indemnity?
What is the largest contractor/customer concentration?

Coverage Gaps Worth Checking

Roofing distributors should confirm how the policy treats outdoor stock, property at contractor jobsites, customer-returned material, coatings or adhesives, and property on boom trucks before final delivery. The products form should be reviewed for vendor status, completed-operations allegations and any exclusions that could become important in a water-intrusion or fire claim.

What a Strong Submission Looks Like

Provide a stock-value schedule by location, peak seasonal inventory, manufacturer list, delivery fleet, rooftop-delivery percentage, boom-truck values, top contractor customers, five-year product claims and loss runs. Photos of the yard, sprinkler information, outdoor-storage controls and written loading procedures can help underwriters understand that the business is more disciplined than a generic building-material yard. For the broader picture across product lines, including products liability, fleet and yard operations, see the building material supplier risk guide.

Construction-Defect Tail and Documentation

Roofing materials can remain part of a building for decades. When leaks appear, contractors, manufacturers and distributors can all be named before the actual cause is established. The supplier should retain purchase, lot, delivery and manufacturer records and document any product substitution. For larger commercial projects, the broker should also review whether the distributor assumes any responsibility for system selection, taper plans, rooftop placement or compatibility of components.

Frequently asked questions

8 questions — start typing to filter

Does products liability cover defective shingles?

It may respond to covered allegations, but warranty/replacement costs can be excluded.

Are rooftop deliveries higher risk?

Yes — hoisting or craning material onto a roof creates real jobsite liability exposure beyond a standard ground-level delivery.

Is roofing stock stored in the open yard automatically covered?

No — outdoor roofing material stock needs to be specifically addressed for weather, theft and catastrophe exposure, since not every commercial property form treats yard inventory the same as building contents.

Should manufacturers add the distributor as an additional insured?

That can be useful when available and appropriate.

Does cargo coverage matter on rooftop and jobsite deliveries?

Yes if the supplier retains transit responsibility.

Can coatings create pollution exposure?

Potentially — roofing coatings, sealants and adhesives can create pollution exposure from spills or improper disposal that a standard general liability policy may exclude.

Should single-ply versus shingle products be tracked separately?

Yes — different roofing material categories carry different failure modes and claim histories, and a submission that lumps them together can understate the real product mix risk.

Does running a manufacturer's certified applicator program change the distributor's exposure?

It can, and in a way that is easy to miss, because the distributor's role moves from supplying material to standing somewhere near the warranty. Certified applicator programs commonly involve the distributor in training, in approving or recommending contractors, and sometimes in inspecting completed work before a manufacturer's system warranty is issued. Each of those is a service rather than a sale. Where a roof fails and the warranty is declined, a building owner who was pointed at a contractor by the distributor may name the distributor too. Underwriters generally want to know whether the firm recommends installers, whether it inspects, and what the paperwork says about who is responsible for what.
