How to Fill Out and Submit a Roofing Contractor Supplemental Application

The roofing contractor supplemental application is the detailed questionnaire your carrier attaches to a standard general liability application, and filling it out well comes down to three things: pulling the right records before you start, answering the high-stakes sections (heat application, height, subcontractors, claims) with specifics rather than guesses, and reading the quote that comes back for exclusions. Most forms run three to five pages, and your answers directly shape premium, deductibles, and whether certain operations are covered at all.

Pull These Records Before You Open the Form

Most supplemental applications ask for at least three years of historical data, so current-year numbers alone will not get you through. Collect the following first:

Gross receipts, direct W-2 payroll, 1099 subcontractor payroll, and total subcontractor costs for the current year plus two or three prior years.
A current Certificate of Insurance from every subcontractor, signed hold-harmless agreements, and records of total payments to each.
A list of major projects completed in the past five years with project type, dollar value, and building height.
Your written safety program, fall protection plan, OSHA 300 logs, employee training certificates (OSHA 10-hour or 30-hour cards), and any OSHA citation history from the past three years.
Loss runs from your current and prior carriers covering at least five years, including paid losses, reserves, and claim descriptions.
Your contractor license number, the year it was issued, and every state where you operate.

Loss runs are the item most likely to delay you. Request them from your current and prior carriers early; some brokers turn them around in a day, others take a week or more. Waiting until the last minute to request loss runs is one of the most common reasons applications stall.

Identification and Exposure Numbers

The opening section captures business name, address, years in business, license number, and the states you work in. Some carriers ask pointed geographic questions. The Argo Group form, for example, asks specifically whether you have worked or plan to work in New York State, the five boroughs of New York City, or Colorado, because those jurisdictions carry elevated liability exposure for construction defect claims.¹

Then comes the exposure table: gross receipts, payroll, subcontractor costs across multiple years. AmTrust asks for the current year, two prior years, and projections for the upcoming twelve months.² Argo Group requests three prior years plus projections.¹ Carriers are looking at whether your revenue and workforce are stable, growing, or volatile, because rapid growth in roofing often outpaces a company’s safety infrastructure.

Accuracy in this section matters more than anywhere else on the form. The carrier verifies these numbers through a premium audit after the policy term ends. If your actual payroll comes in 30 percent higher than projected, you owe the difference plus any surcharge. Report honest figures rather than low-balling to get a cheaper quote.

Breaking Down Your Work by Type

Every supplemental application asks you to split your roofing work into categories, and the totals must equal exactly 100 percent. Crum & Forster splits the question into two axes: residential versus commercial/industrial, and replacement versus new construction, each totaling 100 percent separately.³ Argo Group adds industrial and “other” categories along with a new-construction-versus-remodeling split.¹ Read your specific form carefully; the categories are not identical across companies.

The residential-versus-commercial split often drives premium rates more than any other single field. Commercial and industrial work generally carries higher per-dollar premiums because of larger project values and more complex liability exposure. Some carriers also ask whether you have worked or intend to work on condominiums, townhomes, or tract homes within the past ten years.² Multi-family residential is a red flag because construction defect litigation on those developments tends to involve many claimants and large aggregate losses. A “yes” answer does not automatically disqualify you, but expect follow-up questions.

Materials You Install

You check off or list the specific roofing systems you install. Typical options include asphalt shingles, fiberglass shingles, wood shake, clay or concrete tile, slate, thermoplastic membranes (TPO), EPDM/rubber membrane, metal roof systems, spray polyurethane foam, built-up asphalt or hot tar, modified bitumen, pre-engineered systems, and green roof systems.² The materials you select tell the underwriter what fire, chemical, and warranty risks your operations create. A company installing only asphalt shingles on single-family homes presents a fundamentally different profile than one running torch-down modified bitumen on commercial flat roofs.

Your Role on the Job

Some forms ask what percentage of your work is performed as a general contractor, as a subcontractor, and as a construction manager.¹ A general contractor assumes liability for the entire project, including subcontractors’ work; a subcontractor’s exposure is typically limited to its own scope. If you act as GC on some jobs and sub on others, split the percentages honestly.

Heat Application and Height: The Two Sections That Change Everything

Most coverage restrictions and premium surcharges originate in these two sections. Underwriters treat them as the highest-severity risk indicators on the form.

Heat Application Operations

The Argo Group form asks a direct series of questions: whether you perform any heat application work (hot tar, torch-down, hot air welding, any open-flame work), whether you spray flammable liquids, whether your employees hold NRCA torch application certification, how many years of experience you have with these methods, whether a fire watch is conducted after every heat application job, how long you remain on-site after heat work stops, and whether you maintain a service contract for all tar kettles.¹

Answering “yes” to heat work does more than raise your premium. It can trigger outright coverage exclusions. In one court case involving a contractor’s CGL policy, a roofing endorsement excluded all bodily injury and property damage “arising out of any operations involving any hot tar, wand, open flame, torch or heat applications, or membrane roofing.” Because the contractor used torches, the insurer had no obligation to defend or pay the claim at all. If your policy carries a similar exclusion and you perform heat work anyway, you are effectively uninsured for your riskiest operations. Review the endorsements on any quote you receive, and ask your broker to confirm in writing whether heat application work is covered or excluded.

The strongest answers you can give in this section are certified employees, a documented fire watch protocol with a specific duration (many carriers want at least two hours of monitoring after heat work stops), and a current maintenance contract for all equipment. Weak or missing answers push you toward the surplus lines market, where premiums are substantially higher.

Building Height

Most forms ask whether you perform exterior work above three stories and, if so, what the maximum building height is in feet.² Enter the highest point you have actually worked on during the past twelve months, not an average. If you worked one job at six stories and fifty jobs at two stories, the answer is six stories. Underwriters price for worst-case severity.

Three stories is the common threshold that triggers additional scrutiny. If you answer “yes” to working above that height, expect the carrier to require proof of a written fall protection program and possibly impose a height cap on covered operations. Misrepresenting your maximum height can void coverage entirely if a claim occurs on a taller building than you disclosed.

Safety Program and OSHA Documentation

Your safety program is the clearest signal underwriters have about whether your loss history will stay clean. The AmTrust form asks whether you maintain written procedures for safety rules and regulations, fall protection, subcontractor safety requirements, safety meetings, substance abuse prevention, fire prevention and protection training, site safety inspections, accident investigation and reporting, and hazardous material handling.² Checking “no” on several of these can push standard-market carriers to decline the risk outright.

Fall Protection Plan

Federal OSHA requires employers to provide fall protection for workers on surfaces with an unprotected edge six feet or more above a lower level. For roofing specifically, the regulation allows a fall protection plan as an alternative when conventional systems such as guardrails or personal fall arrest systems are infeasible, but the employer bears the burden of proving that standard methods would create a greater hazard.⁴ Your written plan should be a standalone document, not a generic safety manual. Carriers want to see site-specific procedures, designated competent persons, and documentation that the plan is reviewed before each project.

OSHA Training and Logs

The OSHA Outreach Training Program offers 10-hour and 30-hour course completion cards.⁵ The 10-hour course is designed for entry-level workers; the 30-hour targets supervisors and safety directors. Keep copies of these cards for every employee, because many applications ask about training levels and some carriers require 30-hour certification for all foremen or site supervisors.

Employers with more than ten employees are generally required to maintain OSHA recordkeeping forms, including the OSHA 300 log of work-related injuries and illnesses.⁶ Applications also ask about OSHA citation history over the past three years.² A recent serious citation, especially for fall protection, is one of the fastest ways to get declined by a standard carrier.

Subcontractor Documentation and Risk Transfer

This is the section where roofing contractors most often create expensive problems for themselves without realizing it. Carriers want to know how much you pay subcontractors and how thoroughly you transfer risk away from your own policy.

Certificates of Insurance

You need a current Certificate of Insurance from every subcontractor before they set foot on a job site, confirming the subcontractor carries their own general liability and workers’ compensation coverage. The Crum & Forster form goes further and asks whether you have a tracking system for certificates and what minimum liability limits you require from subcontractors.³

Why this matters in dollars: if you hire a subcontractor who lacks workers’ compensation and that person gets hurt on your job, your carrier will treat the subcontractor’s payroll as if it were your direct employee payroll for premium purposes. The same applies to uninsured general liability exposure. This adjustment happens at audit and can add thousands of dollars to your final premium.

Hold-Harmless and Additional Insured Status

Applications typically ask three related questions: whether you have a standard written agreement with all subcontractors, whether each subcontractor holds you harmless (agrees to indemnify you for losses arising from their work), and whether each subcontractor adds you as an additional insured on their policy.³ A hold-harmless agreement is a contractual promise that the subcontractor will cover liability for their own work. Additional insured status means their insurance policy will respond to claims against you arising from the subcontractor’s operations.

The answer carriers want is “yes” to all three. If you can’t honestly say yes for every subcontractor, say so. Claiming you have universal hold-harmless agreements when you don’t creates a coverage gap that surfaces during a claim, which is the worst possible moment to discover it.

Two endorsement forms matter here. The CG 2010 endorsement provides additional insured coverage during ongoing operations only; it expires the day the subcontractor leaves the job site. The CG 2037 endorsement extends that protection to completed operations after the work is done. If a subcontractor’s faulty installation causes a leak two years later, only the CG 2037 protects you. Requiring both endorsements from every subcontractor is standard practice for well-run roofing firms.

Classifying Workers Correctly

If a form asks about temporary or casual laborers, worker classification comes into play. The IRS uses three factors to determine employee versus independent contractor status: behavioral control, financial control, and the nature of the relationship.⁷ If you provide the tools, set the schedule, and direct the methods, those workers are employees regardless of what your agreement calls them, and your carrier will reclassify their payroll at audit.

Claims History

Most forms ask for five years of loss data in a table: year, paid losses, reserves, incurred totals, and claim counts.³ Individual losses above a threshold (often $10,000) require a separate detailed description including date of occurrence, type of claim, amounts paid and reserved, and whether the claim is open or closed.

Forms also ask broader questions: whether any claim or lawsuit has ever been filed against you, predecessors in business, or any partnership or joint venture you participated in. AmTrust asks whether you have knowledge of any pre-existing conditions or potential claims not yet reported, whether you have been fired or replaced on a job in the past three years, and whether you have been involved in litigation regarding faulty construction in the past eight years.² A lapse in general liability coverage also gets flagged, because it suggests either financial instability or a period of uninsured operations that could still generate late-reported claims.

Open Roof and Weather Procedures

Several carriers devote a separate section to how you handle open roof exposure, the window after tear-off when the interior is vulnerable to weather. The Argo Group form asks whether you have a procedure for limiting the amount of roof opened at one time and whether there are circumstances under which you would leave an unattended open roof for more than two hours.¹ Crum & Forster asks you to describe your procedures for monitoring weather forecasts and protecting an open roof when leaving a job site for an extended period.³

Water damage from an unprotected open roof during a rainstorm is one of the most frequent and expensive property damage claims in roofing. A strong answer describes a specific protocol: checking weather forecasts at the start of each day, limiting tear-off to an area that can be dried in and covered by end of day, keeping tarps and temporary waterproofing materials on every job site, and designating a responsible person to secure the roof before the crew leaves. Vague answers like “we cover it up” don’t inspire confidence.

Equipment

Most forms ask about cranes, booms, scaffolding, and other mobile equipment. The questions cover whether you own, rent, or lease equipment, whether rental agreements include operators, whether you allow other contractors to use your scaffolding, and whether you require OSHA “competent person” certification for anyone who erects scaffolding.¹ Crum & Forster also asks whether you have had any claims or incidents involving cranes or booms in the past five years.³

If you rent cranes or booms with an operator, the rental company’s insurance typically responds first for equipment-related incidents. If you rent without an operator, the liability shifts more heavily onto your policy. Know which arrangement applies before answering, because the distinction affects how the underwriter prices your equipment exposure.

Submitting the Application

Once every field is filled and every checkbox is marked (or explicitly marked “N/A”), sign and date the form. Most supplemental applications include a fraud warning statement above the signature line; signing confirms your answers are accurate to the best of your knowledge. Bundle the completed form with supporting documents: loss runs, Certificates of Insurance from subcontractors, your written safety program, OSHA training records, and any project lists or financial statements the form references.

Most carriers accept submissions through digital portals or secure email through your broker. Paper submissions are increasingly rare but not extinct. Confirm the submission method with your broker before sending, because uploading to the wrong portal or emailing a general inbox will delay processing. A complete, well-organized submission with all attachments typically receives an initial underwriting response within five to ten business days. Incomplete submissions get returned, and the clock restarts once you resubmit.

Read the Quote for Exclusions

Filling out the application correctly does not guarantee full coverage. The quote you receive will include endorsements that may carve out significant categories of work. The common ones to look for:

A heat application exclusion that eliminates coverage for all claims arising from hot tar, open flame, torch, or heat application operations.
A multi-family or condominium exclusion. These are sometimes manuscripted rather than standardized, meaning they may not appear on the declarations page and can only be found by reading the full policy.
The professional liability gap. General liability policies exclude claims arising from design, consulting, inspection, or project management services. If your firm inspects roof systems, offers design-build services, or provides expert witness testimony, you need a separate professional liability policy.
Completed operations limitations. A roof leak that appears three years after installation is a completed operations claim. Confirm your policy includes products-completed operations coverage and understand how long that coverage extends.

Read every endorsement attached to the quote. Ask your broker to walk through each exclusion and explain what it means for your operations. An exclusion you don’t know about is functionally the same as having no insurance for that activity.

What Happens After You Submit

The underwriter reviews your application against the carrier’s internal risk appetite and pricing models. They compare your gross receipts and payroll to your claims history to see whether your loss ratio is acceptable. They evaluate your safety program, subcontractor management, and heat application procedures to gauge future risk. If something doesn’t add up, such as payroll figures that look too low for your reported gross receipts or subcontractor costs without corresponding Certificates of Insurance, expect a follow-up request for clarification.

If the application passes review, the carrier issues a formal quote listing premium, deductibles, coverage limits, and every endorsement or exclusion. If the terms are acceptable, you sign the quote, pay the deposit premium, and the carrier issues a binder, which is temporary proof of coverage that lets you continue working on job sites requiring insurance documentation while the full policy is being generated.

After your policy term ends, the carrier conducts a premium audit to verify that payroll, gross receipts, and subcontractor costs match your actual books. This is not optional. The auditor reviews tax returns, payroll records, and subcontractor payment records. If actual figures exceed what you estimated, you owe additional premium; if they come in lower, you receive a credit. Failing to cooperate with the audit can result in the carrier estimating your exposure at a much higher level, canceling your policy, or both, and a cancellation for audit non-compliance follows you into future applications.
