Compare quotes to balance quality and value, avoiding low bids. These steps will help you find a reliable and skilled roofing contractor in San Jose.

Licensing and Insurance

First, make sure the contractor is licensed, bonded, and insured. A licensed contractor has met the state’s requirements for knowledge and experience. Bonding protects you if the contractor fails to fulfill the contract terms, while insurance covers worker injuries and property damage that could occur during the project.

Reputation and Reviews

Look for a contractor with a solid reputation and positive reviews from past customers. For instance, Diamond Certified roofing contractors serving San Jose have an average rating of 4.6 out of 5 stars based on 4,523 reviews of 95 rated contractors. Read reviews to gauge the contractor’s professionalism, quality of work, and customer service.

Warranty and Guarantees

A reputable contractor should offer a warranty on their work and use high-quality materials with manufacturer warranties. For example, Campbell Roofing provides a one-year warranty for temporary roof repairs. Look for contractors who stand behind their work and provide solid guarantees.

Specialization and Experience

Choose a contractor with experience working on roofs similar to yours. Some specialize in residential, commercial, flat, tile, metal, or other roofing types. Contractors like Shelton Roofing offer various services, including composition, tile, metal, and more. Ensure they have the right expertise for your specific roofing needs.

Communication and Professionalism

A quality contractor will communicate, arrive on time, and treat your property. They should also provide a detailed contract, answer all your questions, and keep you informed throughout the project. Customers praise contractors like Simon Says Roofing for their professionalism and effective communication.

Pricing and Value

Get multiple quotes to compare pricing. Avoid contractors with low bids, as they may cut corners. Look for a good balance of quality and value. Customers say Winter Roofing provides excellent value for the price. Make sure to get everything in writing to avoid surprises.

Detailed Evaluation Criteria

  1. Licensing and Insurance:
    • Licensing: Verify the contractor’s license through the California Contractors State License Board (CSLB). This ensures they can perform roofing work and have met specific standards.
    • Bonding: Bonding protects you if the contractor fails to complete the job or meet other contractual obligations.
    • Insurance: Check that the contractor has general liability and workers’ compensation insurance. This protects you from liability in case of property damage or worker injuries during the project.
  2. Reputation and Reviews:
    • Online Reviews: Check platforms like Yelp, Google, and the Better Business Bureau (BBB) for customer reviews. Consistent positive feedback and high ratings are good indicators of reliability and quality.
    • References: Ask the contractor for references from previous clients. Contact these clients to ask about their experience, the quality of work, and any issues they encountered.
  3. Warranty and Guarantees:
    • Workmanship Warranty: This covers installation errors. Ensure the warranty period is reasonable (1-5 years).
    • Manufacturer Warranty: This covers defects in roofing materials. Verify the duration and terms of the warranty.
  4. Specialization and Experience:
    • Experience: Ask how long the contractor has been in business and how long they have experience with your specific roofing type. More experienced contractors are likely to provide better quality work.
    • Specialization: If you have a specific roofing type, such as tile or metal, choose a contractor specializing in that area. Specialized contractors will be more familiar with the nuances and best practices for your roofing type.
  5. Communication and Professionalism:
    • Initial Consultation: Observe the contractor’s communication style during the initial consultation. They should be attentive, answer your questions, and provide detailed information about the project.
    • Detailed Contract: A clear, written contract should outline the scope of work, materials to be used, project timeline, and payment schedule. This helps prevent misunderstandings and disputes.
  6. Pricing and Value:
    • Quotes: Obtain detailed quotes from multiple contractors. Compare the scope of work, materials, warranties, and prices. Be wary of quotes that are lower than others, as they may indicate lower-quality materials or subpar workmanship.
    • Value: Consider the value, not the price. A higher initial cost may be worth it if it means better materials, a longer warranty, and superior workmanship.

Additional Tips

  • Local Contractors: Choosing a local contractor can be beneficial. They are more likely to be familiar with local building codes and regulations and have a reputation to maintain within the community.
  • Certifications: Look for contractors who have certifications from roofing material manufacturers or professional roofing associations. These certifications often indicate additional training and expertise.
  • Visit: Visit the contractor’s current job site. This can give you a sense of their work habits, cleanliness, and professionalism.


By evaluating factors like licensing, insurance, reputation, warranties, specialization, communication, and pricing, you can find a San Jose roofing contractor who delivers quality work at a fair price. Proper evaluation is crucial for ensuring your roofing project is completed and to your satisfaction. Always do your due diligence and vet potential contractors before deciding.
