Asking detailed questions helps you evaluate a contractor’s experience, reliability, and professionalism. It ensures you understand the scope of the work, the materials they’ll use, and the warranties they offer. This guide will walk you through the crucial questions to ask to ensure you hire a trustworthy and skilled professional.

Here’s what we’ll cover:

Hiring a roofing contractor is a significant investment, and you want to be sure your money is well spent. Properly vetting potential roofers helps you avoid scams, shoddy workmanship, and unexpected costs down the line. A thorough screening process ensures you partner with a company that is qualified, reputable, and a good fit for your specific project.

Taking the time to ask the right questions provides several key benefits:

  • Peace of Mind: Knowing you’ve hired a licensed, insured, and experienced professional gives you confidence that the job will be done right.
  • Financial Protection: Verifying insurance and warranties protects you from liability in case of accidents and ensures your investment is covered against defects.
  • Clear Expectations: A detailed contract and open communication prevent misunderstandings about project scope, timelines, and costs.
  • Quality Assurance: Inquiring about materials, techniques, and past work helps you gauge the quality you can expect from the contractor.

Before you sign any contracts, it’s vital to have a comprehensive conversation with potential roofing contractors. These questions are designed to cover all the essential bases, from legal qualifications to project specifics.

Here are the top 10 questions you should ask to ensure you’re hiring a reliable and professional roofer.

1. Are You Licensed and Insured?

This should always be your first question. A reputable contractor must have the proper licensing required by your state and carry both liability insurance and workers’ compensation.

  • Liability Insurance: This protects your property from any damage that might occur during the project.
  • Workers’ Compensation: This covers the contractor’s employees if they are injured on your property, protecting you from potential legal issues.

2. Can You Provide a List of References?

A confident and experienced roofer will be happy to provide references from previous clients. Speaking with past customers gives you firsthand insight into the contractor’s work quality, professionalism, and reliability.

  • Ask for references from recent projects that are similar to yours.
  • Inquire about their overall satisfaction, communication with the contractor, and whether the project was completed on time and on budget.

3. What Roofing Materials Do You Specialize In?

Different roofers may have expertise in specific types of materials, such as asphalt shingles, metal, or tile. It’s important to know if their skills align with your preferences and your home’s needs.

  • Ask for their recommendations for your specific roof and climate.
  • Inquire about the brands they use and why they prefer them. A good roofer uses high-quality materials from trusted manufacturers.

4. Who Will Be in Charge of the Project?

Understanding the team structure is important for clear communication. You should know who your main point of contact will be throughout the project.

  • Ask if they use subcontractors. If they do, confirm that the subcontractors are also licensed and insured.
  • Find out who the project manager is and how you can best reach them with questions or concerns.

5. Will You Provide a Detailed Written Estimate?

Never accept a verbal quote. A professional roofer should provide a detailed, written estimate that breaks down all the costs associated with the project.

  • The estimate should include the cost of materials, labor, permits, and any other potential charges.
  • Ensure the estimate specifies the type and brand of materials to be used.

6. What Warranties Do You Offer?

Roofing warranties typically come in two parts: one for the materials and another for the workmanship. Understanding what’s covered is crucial for your long-term protection.

  • Material Warranty: This is provided by the manufacturer and covers defects in the roofing materials themselves.
  • Workmanship Warranty: This is provided by the contractor and covers errors in installation. At Kornerstone Roofing, we offer 10-25 year labor warranties.

7. How Will You Protect My Property During the Project?

A roofing project can be messy. A professional contractor will have a clear plan for protecting your landscaping, driveway, and other parts of your property from damage.

  • Ask about their process for covering plants, windows, and siding.
  • Inquire about their cleanup process after the job is completed. They should leave your property as clean as they found it.

8. What Is the Expected Timeline for the Project?

A reliable contractor should be able to provide a clear timeline for the project, from start to finish. This helps you plan accordingly and sets clear expectations.

  • Ask for an estimated start and completion date.
  • Find out what factors, like weather, could potentially delay the project and how they handle such situations.

9. How Do You Handle Unexpected Repairs?

Sometimes, underlying issues like rotted decking are discovered only after the old roof is removed. It’s important to know how the contractor will handle these surprises.

  • Ask about their process for addressing unexpected problems.
  • Ensure the contract specifies how additional costs will be handled and approved by you before any extra work is done.

10. What Are Your Payment Terms?

Clear payment terms prevent financial misunderstandings. You should know exactly what is expected of you regarding payment before the project begins.

  • Ask about the required down payment and the payment schedule for the remainder of the balance.
  • Be wary of any contractor who asks for the full payment upfront.

⚠️ Red Flags to Watch For

While asking the right questions is key, it’s also important to be aware of potential warning signs when dealing with roofing contractors. These red flags can indicate that a contractor may not be reliable or trustworthy.

Keep an eye out for the following:

  • High-Pressure Sales Tactics: A reputable contractor will give you time to consider their estimate without pressuring you to sign a contract on the spot.
  • Vague or Missing Details in the Contract: The contract should be detailed and clear. If it’s vague about materials, costs, or timelines, it’s a major red flag.
  • Requesting a Large Upfront Payment: While a down payment is standard, demanding the full amount or a very large percentage before work begins is a warning sign.
  • Lack of a Physical Business Address: A legitimate contractor should have a physical office or place of business. Be cautious of those who only have a P.O. box or an unmarked truck.
  • Unwillingness to Provide References: If a contractor is hesitant or refuses to provide references, it could mean they have a history of unsatisfied customers.
