Questions to Ask When Getting a New Roof

Meta description: Use these questions to compare roofing contractors, understand estimates and warranties, and prepare for a new roof installation in the United States.

A new roof is a major home investment, and the lowest estimate may not cover the same materials or work as a competing bid. Before hiring a roofer, homeowners can ask about licensing, insurance, installation details, ventilation, permits, cleanup, payment, and warranties. Clear answers make it easier to compare proposals and spot gaps before work begins. This guide covers practical questions to ask when getting a new roof, plus the documents and details to check before signing a contract.

Questions to Ask Before Hiring a Roofing Contractor

A contractor’s experience and business practices affect the quality of the installation as much as the roofing material does. Ask for specific information rather than relying on general assurances. Requirements vary by state and locality, so homeowners should confirm local rules with their building department and relevant licensing agency.

Are You Licensed, Insured, and Established Locally?

Ask whether the contractor holds any license required in the state or municipality. Licensing rules differ across the United States; a roofer may need a state license, a local registration, or both. Verify the license with the issuing agency when applicable, and ask whether the company has a physical business address and a track record in the area.

Request proof of general liability insurance and workers’ compensation coverage. General liability can help address certain property-damage claims, while workers’ compensation generally covers eligible employees injured on the job. Requirements and coverage vary. Homeowners can confirm policy details with the insurer and ask whether subcontractors are covered. A certificate of insurance is useful, but it should be verified with the insurance company rather than treated as a guarantee by itself.

Can You Provide References and Recent Projects?

Ask for references from recent projects with a similar roof type, material, or scope. Contacting past customers can reveal whether the crew arrived as scheduled, protected landscaping, communicated changes, and handled problems after installation. If possible, view a completed roof in person, with the homeowner’s permission.

Online reviews can provide context, but they should not replace references, documentation, or a written contract. Look for patterns across multiple reviews, including how the company responds to complaints. Ask how long the company has operated under its current name and whether it has changed ownership or business structure.

Who Will Supervise the Job and Perform the Work?

Ask who will be the on-site supervisor and how the homeowner can reach that person during the project. Find out whether the contractor uses employees, subcontractors, or a mix. Subcontracting is common, but the written agreement should identify who is responsible for workmanship, safety, scheduling, and resolving issues.

Ask how many workers are expected, when work usually begins, and how weather delays are handled. A clear communication plan helps prevent confusion about access, noise, pets, and updates if the schedule changes.

Questions to Ask About the Roof Inspection and Estimate

Before comparing prices, make sure each bid addresses the same work. A contractor should inspect the roof and explain the basis for the recommended replacement. A quick quote based only on roof area may miss details that affect the project’s scope and cost.

What Did the Inspection Find?

Ask for photos or other documentation showing damaged, worn, or vulnerable areas. The contractor should explain whether the roof needs a full replacement or whether repairs are a reasonable option. Ask about the condition of flashing, valleys, penetrations, gutters, roof decking, and ventilation—not just the visible shingles or other surface material.

Roof inspections from the ground or by drone can help document visible conditions, but they may not reveal hidden damage beneath the roofing. Ask how the contractor will assess the deck once the old material is removed and what steps will follow if concealed damage is found.

What Exactly Is Included in the Written Estimate?

Request an itemized proposal that identifies materials, labor, tear-off, disposal, flashing, underlayment, ventilation work, and cleanup. It should describe the roofing system and the approximate quantities or measurements used to price it. Ask whether the estimate includes replacement of pipe boots, drip edge, valleys, ridge components, and other details that apply to the roof.

Confirm whether the contractor plans to install a new roof over existing shingles or remove the old roofing first. Local building codes, the roof’s condition, and manufacturer instructions can affect what is allowed. Ask the contractor to explain the chosen method and any limitations. If removal is included, clarify how many existing layers the price covers and how additional layers would be priced.

How Are Hidden Repairs Priced?

Decking damage, rot, and other concealed problems may only become visible during tear-off. Ask what the estimate assumes about the roof deck and how extra work will be approved and charged. A sound contract should explain the unit price for replacement materials or labor, how the contractor will document the issue, and whether the homeowner must approve the cost before the work proceeds.

Be cautious of open-ended language that allows substantial additional charges without a defined process. Homeowners should receive photos or a written description of unexpected damage, along with a change order stating the added work and price.

Questions About Roofing Materials and Installation

The right roof depends on the home’s structure, roof slope, climate, local code, budget, and design preferences. A contractor should explain how the proposed product fits the property rather than recommending a material solely because it is familiar or inexpensive.

Which Roofing Material and Product Are You Proposing?

Ask for the manufacturer, product name, material type, color, and relevant product documentation. Common U.S. residential options include asphalt shingles, metal roofing, tile, and slate, but not every material suits every structure or budget. Compare expected service life as an estimate rather than a guarantee; climate, installation quality, maintenance, and ventilation can affect performance.

Ask whether the product is appropriate for the roof’s slope and local weather exposures, including wind, heavy rain, snow, or wildfire risk where relevant. Check local building requirements and product approvals. In some locations, rules may address wind resistance, fire classification, ice barriers, or other performance features.

What Underlayment, Flashing, and Accessories Will Be Installed?

Roof performance depends on more than the visible covering. Ask what underlayment will be used and where, including whether self-adhering ice-barrier membrane is required or recommended at eaves, valleys, or other vulnerable areas. Requirements vary by code and climate, so the contractor should explain the specification for the home.

Flashing directs water away from joints and roof penetrations. Ask whether existing flashing will be reused or replaced and how walls, chimneys, skylights, valleys, and plumbing vents will be handled. Reusing old flashing may be appropriate in some situations, but the reason should be clear and included in the proposal.

How Will Roof Ventilation Be Evaluated?

Ask whether the contractor will assess attic ventilation and explain the planned intake and exhaust strategy. Ventilation should be considered alongside insulation, air sealing, roof design, and local conditions. Adding a ridge vent alone does not necessarily solve a ventilation problem if adequate intake air is missing or the system is not balanced.

Ask what changes are included, how existing vents will be treated, and whether the proposal accounts for ventilation products compatible with the chosen roof system. The U.S. Department of Energy and building authorities provide general guidance on home energy and building practices, but the appropriate design should be determined for the specific structure and local code.

Questions About Permits, Timing, and Site Protection

Permits and inspections are generally managed under local rules. Homeowners should not assume that a contractor’s estimate automatically includes permit fees or that every roof replacement requires the same approvals.

Who Obtains the Permit and Schedules Inspections?

Ask whether a permit is required and who will obtain it. Confirm whether permit costs are included in the estimate and who will arrange any required inspections. Homeowners can check requirements directly with the local building department. Keeping permit records and inspection results with the project documents can be useful if questions arise later or the home is sold.

What Is the Schedule, and How Will Weather Delays Be Managed?

Ask for an estimated start date, project duration, and factors that could change the schedule. Roof work depends on weather, material availability, crew schedules, and the extent of hidden repairs. The contract should describe how delays and schedule updates will be communicated.

Ask how the contractor will protect the home if rain is forecast or work is interrupted. A responsible plan should address temporary coverings and the steps used to keep the structure protected between workdays, while recognizing that severe weather can still create unexpected conditions.

How Will You Protect the Property and Clean Up?

Ask how crews will protect landscaping, siding, windows, decks, driveways, and outdoor equipment. Find out where materials and a dumpster will be placed, whether driveway access will be blocked, and how debris will be collected. Homeowners should move vehicles and fragile items as directed before work begins.

Clarify whether cleanup includes magnetic collection of roofing nails and whether the crew will inspect gutters and the surrounding property. Ask how waste will be disposed of and whether old materials will be recycled when practical. Cleanup expectations should be stated in the agreement, not left to assumption.

Questions About the Contract, Cost, and Payment

A detailed contract gives both parties a shared record of what the project includes. Before signing, compare the written scope with the estimate, product information, and any promises made during sales discussions.

What Is the Total Price, and What Could Change It?

Ask for the total contract price, payment schedule, included fees, and a clear list of exclusions. Confirm whether the price covers tear-off, disposal, permits, material delivery, and ordinary cleanup. Make sure any allowances—such as a budget for decking replacement—are explained, including how the final amount will be calculated.

Ask for changes to be documented in writing before additional work begins whenever conditions allow. The change order should identify the reason, added work, price, and effect on the schedule. This process helps avoid disputes over verbal agreements.

When Are Payments Due?

Ask what deposit, progress payments, and final payment are required, and connect each payment to a clear project milestone. Payment rules vary by state, and some states limit deposits or regulate home-improvement contracts. Check local consumer-protection guidance before making a large upfront payment.

Avoid paying the full amount before the work is complete and the agreed cleanup and documentation are delivered. Use payment methods that create a record, and keep copies of invoices, receipts, and signed change orders. If the contractor offers financing, review the lender’s terms separately from the roofing contract.

Questions About Roofing Warranties and Final Documentation

“Warranty” can refer to different protections, so homeowners should ask what each one covers, who provides it, and how to make a claim. Written terms matter more than a verbal description.

What Do the Manufacturer and Workmanship Warranties Cover?

Ask for the manufacturer’s warranty document for the exact product and the contractor’s separate workmanship warranty. Manufacturer coverage generally concerns specified product defects, subject to its terms; it does not automatically cover every leak or installation problem. Workmanship coverage relates to the installer’s work, but duration, exclusions, transferability, and claim procedures vary by contractor.

Ask when coverage begins, whether registration is required, whether the warranty can transfer to a future owner, and what maintenance or documentation is needed. Check exclusions for ventilation, storms, foot traffic, unauthorized repairs, or other conditions. A longer advertised warranty is not necessarily broader protection.

What Documents Will Be Provided at Completion?

Ask for the final invoice, proof of payment, permit and inspection records where applicable, product and warranty documents, and any photographs of completed work or concealed repairs. Confirm that the final documents identify the installed materials and the contractor responsible for the work.

Before final payment, review the finished roof from a safe location and address any incomplete items in writing. Homeowners should not climb onto a roof to inspect it; a contractor can provide photos or arrange a safe review. Keep all records with the home’s maintenance documents.

Roofing Contractor Comparison Checklist

When comparing bids, use the same questions for each contractor and evaluate the full scope rather than price alone. A low bid may omit removal, flashing, ventilation, permits, or disposal that another proposal includes.

Topic	What to Confirm
Credentials	Required license or registration, insurance, local business details, references
Scope	Removal, materials, underlayment, flashing, ventilation, decking assumptions, cleanup
Cost	Total price, exclusions, allowances, change-order process, payment milestones
Project plan	Supervisor, crew arrangement, schedule, weather protection, property protection
Compliance	Permit responsibilities, local code requirements, inspection arrangements
Warranty	Manufacturer and workmanship terms, exclusions, registration, transferability

The strongest roofing proposal is specific, written, and easy to compare. Homeowners who ask these questions before getting a new roof can better understand what they are buying, reduce preventable surprises, and choose a contractor whose plan fits the home and local requirements.
