To ensure a roofing contractor is trustworthy, check if they have a license and insurance. You can do this by asking for proof and checking with your state’s licensing board.


Look up what others have said about them online and see if they’re part of groups like the National Roofing Contractors Association (NRCA). See how much experience they have by looking at their past work and asking for names of people they’ve worked for before.

Also, ask them to write down how much things will cost, their promises about their work, and the materials they use. Watch out for warning signs like not having a good online profile, pushing you too hard to make a quick decision, or not wanting to share important details.

Check Licensing and Insurance

Verifying a roofing contractor’s state licensing and ensuring they have proper insurance coverage are crucial first steps to protect yourself and your property during a roofing project.

  • State Licensing: Each state has its requirements for roofing contractors. It’s important to check that the contractor you’re considering is licensed to work in your state. This information can be found on the websites of state licensing boards.
  • Insurance Coverage: A reputable contractor will have liability and worker’s compensation coverage. This protects you in case of accidents or damage during the roofing project. Always ask for proof of insurance and verify its validity with the insurance company.

Research and Reputation

Researching a roofing contractor’s reputation through online reviews and checking their certifications and affiliations are crucial to hiring a professional committed to quality and reliability.

  • Online Reviews and Testimonials: Look up the contractor online. Websites like Yelp, Google Reviews, and the Better Business Bureau are great places to find reviews. Positive feedback from previous clients is a good sign of a reputable contractor.
  • Certifications and Affiliations: Credentials from roofing material manufacturers or memberships in professional organizations like the National Roofing Contractors Association (NRCA) show a commitment to professionalism and quality.

Evaluate Experience and Expertise

Evaluating a roofing contractor’s experience and expertise is crucial. It involves examining their past projects and insisting on receiving detailed written estimates.

  • Past Projects and References: Ask the contractor for examples of their work and previous clients’ references. This will give you an idea of their experience and the quality of their work.
  • Written Estimates: A detailed written estimate should include a breakdown of the costs, materials, and scope of work. This transparency helps you understand what you’re paying for and compare quotes from different contractors.

Warranties and Guarantees

Warranties and guarantees are crucial for ensuring the quality and longevity of roofing work, covering both the workmanship of the contractor and the materials used in the project.

  • Workmanship Warranties: A trustworthy contractor will offer a warranty on their workmanship. This protects you in case of issues with the installation or repair work.
  • Material Warranties: Ask about the manufacturer’s warranties on the used roofing materials. Understanding the coverage and duration of these warranties is important for your long-term peace of mind.

Red Flags to Watch Out For

Being aware of certain red flags when choosing a roofing contractor can help you avoid scams and ensure you work with a reliable professional.

  • Poor Online Presence: A lack of a professional website or online reviews can be a red flag. It might indicate a lack of established business practices or experience.
  • High-Pressure Sales Tactics: Be wary of contractors who pressure you to make a quick decision, especially if they’re offering a “deal” that seems too good to be true.
  • Lack of Transparency: A reputable contractor will be transparent about their licensing, insurance, and job estimates. Avoid contractors who are hesitant to provide this information.

Additional Tips

To ensure you choose a reputable roofing contractor, consider these additional tips, which focus on their online presence, industry affiliations, communication practices, and history and role in the community.

  • Professional Website and Customer Reviews: A professional website and positive reviews indicate a contractor’s reliability. Look for testimonials and a gallery of past projects.
  • Trade Association Memberships: associations like the NRCA suggest adherence to industry standards and ongoing professional development.
  • Clear Communication and Written Estimates: A credible contractor will communicate and provide detailed written estimates. This ensures that you and the contractor are on the same page regarding the project’s scope and cost.
  • Industry Longevity and Community Involvement: Contractors who have been in the business for a long time and are involved in their community are often more reliable and committed to quality work.


You can determine their trustworthiness by checking a roofing contractor’s license and insurance, researching their online reviews and professional affiliations, reviewing their past work, asking for references, and getting detailed estimates and warranty information.

Be alert for warning signs like a poor online presence, pressure to make quick decisions, or a lack of clear information. Doing this research beforehand can prevent future problems and help ensure a reliable professional completes your roofing project.
