Short Summary

  • Evaluate roofers by asking key questions to verify business transparency, licensing and insurance, experience, and specializations.

Evaluating Roofing Contractors: Key Questions to Ask roofers

Questions to Ask a Roofer Before Hiring

To begin, inquire with the roofing company about checking or inspecting your roof, including the attic, for any work that may be necessary to give the best roof repair. This involves, among other things, checking for leaks, excessive moisture, and adequate ventilation. Then enquire about how any issues may be rectified for your roofing system on your next roof installation.

Selecting the right roofer is vital in guaranteeing a long-lasting, leak-free roof for your home. Evaluating roofing contractors involves considering their business transparency, licensing and insurance, and experience and specializations. Asking key questions can help you uncover crucial information about the contractor and their installation practices, enabling you to make a confident decision.

Most homeowners only have their roof replaced once or twice in their lifetime. Therefore, it’s essential to ensure that you hire an experienced contractor the first time around to avoid costly mistakes. Proper installation is crucial for obtaining limited warranty coverage from shingle manufacturers, so don’t be afraid to ask a roofer about their credibility and expertise.

Business Transparency and Credibility

Business Transparency and Credibility

A reputable roofing contractor should be transparent about their business information and provide evidence of their credibility. Checking state and federal directories for their legal business name can help you verify that they are a legitimate operation.

Requesting before and after photographs of a roofer’s work demonstrates their openness and allows you to assess the quality of their projects. Additionally, hiring a roofer associated with a manufacturer can ensure that they have a deep understanding of how to install that specific company’s products, leading to a better-quality roof.

Insurance and Licensing

When it comes to insurance and licensing, it’s essential to ask your roofer for proof of their qualifications and coverage. A roofing contractor should carry general liability insurance and workers’ compensation to protect both you and their employees in case of accidents or property damage.

To determine the required level of roofing insurance in your state, search for the state’s official website and review the roofing insurance requirements. Ensuring the website is a.gov domain guarantees accuracy. Don’t hesitate to ask your roofer about their licensing and coverage, as it’s a crucial aspect of their credibility.

Experience, Specializations and Warranties

Experience, Specializations and Warranties

A contractor’s experience and specializations can significantly impact the quality of your roofing project. Inquiring about their proficiency in the particular roofing work you require, as well as their qualifications and certifications, is essential. Before you get a roof estimate, is it a written estimate? questions to ask the roofer: Does the roofing company have a warranty and general liability insurance?

While experience is an important factor, be sure to consider other aspects as well, such as their reputation, transparency, and ability to provide references. Ultimately, a well-rounded evaluation of a roofing contractor will help you choose the best fit for your new roof project.

In-Depth Roofing Process Questions

Before committing to a roofing contractor, it’s crucial to delve deeper into the specifics of their roofing process. Inquiring about installation methods and materials, project supervision and quality control, and warranty information can shed light on their approach and help you determine if they’re the right fit for your new roof project.

A comprehensive, compatible system of roof components is essential for a successful roofing job. Asking in-depth questions about the roofing process and components ensures that all aspects of the project will function cohesively, avoiding any difficulties during the installation.

Installation Method and Materials

Understanding the materials a roofer will use and their installation process is vital for a successful project. Ask about their preferred method for valley installation, as well as any cold-weather installation practices they employ if the weather is unfavorable on the installation day.

Be wary of roof layovers, as they can negatively impact the health of your roof due to the additional weight of new shingles. A full roof replacement is often the better option to ensure a long-lasting, problem-free roof.

Project Supervision and Quality Control

Project Supervision and Quality Control

Project supervision and quality control are essential aspects of a successful roofing project. Having a project supervisor present during the installation guarantees that the project is executed accurately and in a timely manner.

Inquire about who will be overseeing the project and the methods they use to guarantee quality control. Knowing that an experienced project manager will be present during the installation can provide peace of mind and reassurance that your roofing project is in good hands.

Warranty Information

Warranty information is crucial in safeguarding your investment in a new roof. When discussing warranties with your roofer, be sure to ask about both the manufacturer’s warranty and their workmanship warranty.

Bear in mind that if materials are not installed in accordance with the manufacturer’s specifications, the manufacturer’s warranty may become void. Ensuring that your contractor adheres to proper installation guidelines is critical to protect your warranty coverage.

Researching Reviews and References

Once you’ve asked your prospective roofer all the important questions, it’s time to conduct your own research. Investigating reviews and references for roofers is essential to guarantee superior work and ensure you’re making an informed decision.

Online reviews can be found on websites like Google, Yelp, Angie’s List, Home Advisor, and the Better Business Bureau. These platforms provide valuable insights into a contractor’s performance and customer satisfaction like our reviews listed below.

Online reviews can offer a wealth of information about a roofing contractor’s performance, professionalism, and customer service. Websites like Angi, Houzz, and Porch, along with the Better Business Bureau directory, provide reviews and ratings of roofing contractors.

When evaluating online reviews, keep an eye out for recurring themes, such as consistent complaints or high praise for specific aspects of a contractor’s work. This information can help you make a more informed decision about which roofer is best suited for your project.

Personal References

In addition to online reviews, personal references can offer invaluable insights into a contractor’s work. Request at least three references from the past five years from your prospective roofer.

When contacting these references, ask open-ended, specific questions about the type of project the contractor completed and the quality of their service. This firsthand information can help you make a more informed decision about which roofing contractor to hire.

Comparing Quotes and Making a Decision

After researching reviews and references, it’s time to compare quotes and make a decision. It’s generally advised to obtain a minimum of 2-3 quotes for comparison purposes. Analyzing costs and services in each estimate can help you make an informed decision and ensure that you’re getting the best value for your money.

Trusting your instincts when assessing costs and services is essential. If something doesn’t feel right or if a quote seems too good to be true, it’s important to trust your gut and continue your search for the right roofing contractor.

Analyzing Costs and Services

When comparing quotes, evaluate the line-by-line items in each estimate to ensure they are comparable. The average cost for a new roof is approximately $10,000, while repair costs can range from $100 to $6,000, depending on the severity of the damage.

Analyzing Costs and Services

Selecting a roofer who prices the job ethically and knowledgeably, taking into account all relevant factors, is crucial to ensuring a successful project. Be cautious of quotes that are significantly lower than others, as they may indicate a lack of experience or substandard work.

Trusting Your Instincts

Relying on your intuition is crucial when choosing a roofing contractor. Pay attention to how your prospective contractor communicates and addresses your concerns. If something doesn’t feel right or if their answers don’t align with your expectations, it’s essential to trust your instincts and continue searching for the right contractor.

To ensure that you’re making the best decision, consult with peers, review customer feedback, and request references. Ultimately, it’s crucial to feel confident in your choice of a roofing contractor to guarantee a successful project.

Additional Considerations for Complex Roofing Projects

Complex roofing projects may require additional considerations, such as skylights and ventilation, or unique roofing materials and designs. When undertaking these projects, it’s crucial to account for these unique variables, ensure adequate labor, and make use of materials experts.

Whether you’re installing skylights or opting for a unique roofing design, it’s essential to work with a contractor who understands the specific requirements of your project and can provide the expertise necessary to ensure a successful outcome.

Skylights and Ventilation

Proper installation of skylights and ventilation systems is crucial to prevent water damage and ensure a healthy, energy-efficient home. Mounting skylights and smoke vents above the roofing is recommended to ensure leak-free performance.

Additionally, properly sealing joints and balancing the system with intake and exhaust vents can further guarantee the effectiveness of your skylights and ventilation systems. If you’re considering adding these features to your roofing project, it’s essential to choose a contractor with experience in this area.

Unique Roofing Materials or Designs

Utilizing unique roofing materials or designs can offer a distinctive aesthetic and feel to your home, as well as providing additional advantages such as energy efficiency and durability. Some examples of unique roofing materials include synthetic tiles, recycled composite shingles, living roofs, and copper roofs.

When embarking on a project with unique roofing materials or designs, it’s imperative to work with a contractor who has experience in these areas and can provide the expertise necessary to ensure a successful installation. Don’t be afraid to ask your prospective contractor about their experience with unique roofing projects.


In conclusion, asking the right questions and conducting thorough research can significantly impact your roofing project’s success. By evaluating roofing contractors, asking in-depth roofing process questions, researching reviews and references, comparing quotes, and considering additional factors for complex projects, you can make an informed decision and find the best contractor for your unique needs. Remember, a well-installed, leak-free roof can protect your home for decades to come, so take the time to ask the essential questions and find the perfect roofer for your project.
