What to Look for When Hiring a Roofer

Wondering what to look for when hiring a roofer? Look for a contractor who is licensed, insured, and experienced with local roofing codes. Ask if they provide detailed roofing quotes and are transparent about timelines and materials. A professional roofing contractor should offer references and a clear plan for the project.



Top 10 Questions to Ask a Roofing Contractor Before Hiring

One of the most common questions homeowners search online is: “What should I ask a roofer before signing a contract?” Here are ten essential questions to get you started:


  1. Are you licensed and insured?

    Licensing ensures the contractor meets local standards and regulations, while insurance protects you from liability if something goes wrong on the job.

  2. How many years of experience do you have with residential/commercial roofs?

    Experience matters. A contractor with years in the business is more likely to handle challenges and deliver quality work for your specific type of roof.

  3. Can you provide references or photos of past projects?

    References and photos give you proof of the contractor’s capabilities, so you can check their work quality and speak with past clients.

  4. What warranties do you offer on labor and materials?

    Warranties protect you from defects or issues down the line. A reputable contractor stands behind their work and the materials they use

  5. Will you provide a detailed, written estimate?

    A written estimate outlines costs, timelines, and materials, ensuring transparency and helping you avoid unexpected expenses later.

  6. How do you handle unexpected costs or project delays?

    Unexpected issues can arise. A good contractor will explain how they manage changes to timelines or budgets, keeping you informed.

  7. What roofing materials do you recommend for my property?

    The right materials depend on your location, budget, and preferences. A knowledgeable contractor will suggest durable and efficient options.

  8. Do you handle permits and inspections?

    Handling permits and inspections shows the contractor knows local regulations and can ensure your project complies with codes.

  9. Will there be a dedicated project manager on-site?

    A dedicated manager ensures communication, oversees work quality, and addresses any issues promptly, keeping the project on track.

  10. What safety protocols do you follow?

    Safety protocols protect workers and your property. A professional roofer will have clear procedures to minimize risks on-site.


These questions don’t just cover the basics, they’re designed to help you spot red flags early.



Key Certifications and Warranties to Request

A certified roofing contractor offers peace of mind. Be sure to ask for proof of certifications, such as GAF Master Elite or CertainTeed credentials. Don’t forget to ask about warranties for materials and workmanship. When hiring a roofing contractor in San Jose, it's advisable to verify their certifications and inquire about the specific warranties they offer. These credentials not only demonstrate a contractor's commitment to quality but also provide you with enhanced warranty options that can protect your investment for years to come.



How to Compare Roofing Estimates and Quotes

Getting multiple roof replacement estimates can be overwhelming. Focus on comparing materials, labor costs, project timelines, and warranty details. Look for detailed quotes that break down each aspect of the job. If financing options are available, such as through GBR Roofing, ask about them to make the investment more manageable.

Watch for red flags like unclear estimates, missing credentials, or pushy sales tactics.

Red Flags When Choosing a Roofing Contractor

Beware of contractors who pressure you into signing right away, offer extremely low bids, or can’t provide a physical address. A lack of clear contracts, vague answers to your questions, or evasiveness when asked for details are major red flags. Always trust your instincts when something doesn’t feel right and take time to research thoroughly.



Is There a Difference Between Residential and Commercial Roofing Contractors?

Residential and commercial roofing contractors offer different expertise. Residential roofing focuses on homes, often using materials like asphalt shingles or metal roofing. Commercial roofing, on the other hand, involves flat roofs and specialized materials. While both types of contractors handle roofing projects, commercial roofing often involves larger-scale jobs with different materials and structural requirements. If you’re looking for a commercial roofing contractor in San Jose, GBR Roofing has the expertise and equipment to handle both residential and commercial projects, including metal roofing solutions.

Not sure which roofing material is right for your property? Options include asphalt shingles, metal roofing, and tile. Your roofing contractor should help you choose the best option for your budget and location. In addition to materials, a trusted contractor like GBR Roofing will also offer a full range of roofing services including roof maintenance, emergency roof repair, and solutions to prevent future leaks.



Local Considerations for Roof Contractors in San Jose CA

Hiring local matters. Local roofing contractors in San Jose, CA, like GBR Roofing, understand regional weather challenges and building codes. They’re also more likely to offer faster service and better warranty support. Plus, supporting local businesses helps the community thrive.
