Consider Bay Valley Roofing & Solar if...
- ✓ You need actual roofing work performed, from inspection and diagnosis through installation and cleanup, with a contractor managing the entire project.
- ✓ Your project involves complexity beyond simple material replacement, such as storm damage assessment, leak diagnosis, water intrusion troubleshooting, or solar panel coordination.
- ✓ You value detailed photo documentation during inspection, clear proposals with options explained, and responsive communication throughout the project timeline.
- ✓ You're managing the project remotely and need a contractor comfortable with video calls and phone coordination for planning and updates.
Consider Enterprise Roofing Service Inc if...
- ✓ You're a contractor or experienced DIY property owner specifically seeking roofing materials rather than installation services.
- ✓ You need to match discontinued, vintage, or hard-to-find roof tiles or shingles that standard suppliers don't carry, particularly for restoration work on older homes.
- ✓ You're willing to work by appointment only and your primary need is material sourcing expertise rather than installation labor.
- ✓ You already have an installer lined up and need a specialized supplier with extensive inventory and matching capabilities for your specific material requirements.
Questions to Ask Before Hiring
- → Ask Enterprise Roofing directly whether they perform installation work and, if so, request references from recent residential installation projects with homeowner contacts you can verify.
- → If Enterprise does offer installation, ask how their crew structure works, how long installers have been with the company, and what the typical project timeline looks like from contract to completion.
- → Ask Bay Valley for references from projects similar to yours in scope and complexity, particularly if your roof involves potential hidden damage or solar integration.
- → Clarify what happens if issues arise after installation with Bay Valley, and confirm their process for warranty work and follow-up troubleshooting.
The Bottom Line
If you need roofing work actually performed, Bay Valley Roofing & Solar is the clear choice for this comparison. They operate as a full-service installation contractor with 13 years of documented experience completing roof replacements, repairs, and solar integration projects. Enterprise Roofing Service Inc appears to function primarily as a materials supplier specializing in vintage and hard-to-find tiles, which serves contractors and DIY property owners but doesn't address typical homeowner needs for installation services. Contact Bay Valley for a detailed inspection and proposal if you're ready to move forward with roofing work. Only contact Enterprise if you've confirmed they perform installations or if you specifically need specialty materials sourced.

Frequently Asked Questions
Based on available customer feedback, Enterprise functions primarily as a materials supplier with expertise in sourcing hard-to-find tiles and shingles. Reviews describe efficient material selection and delivery service by appointment, but don't reference installation crews or completed roofing projects. You should ask them directly about installation services and request recent project references if they indicate they perform this work.
Thirteen years places Bay Valley in the established tier, meaning they've navigated multiple business cycles and handled diverse roofing challenges. Customer feedback describes successful completion of complex projects including storm damage assessment, water intrusion troubleshooting, and solar integration work. This experience level is generally sufficient for diagnosing hidden problems and managing complications that arise during installations.
You wouldn't for typical roofing work. Enterprise's value proposition centers on their extensive inventory of vintage and discontinued materials for restoration projects. If you're a contractor sourcing specialty tiles, or managing your own installation and need hard-to-match materials, their 62 years of supplier expertise becomes relevant. For homeowners needing roofing work performed, a full-service contractor like Bay Valley is the appropriate choice.
Customer feedback indicates Bay Valley has completed solar shingle installations and coordinated solar panel removal and reinstallation during roof replacements. However, reviews note that solar servicing may be limited, so if your project involves complex solar system work beyond basic coordination, ask specifically about their capabilities and whether they subcontract any solar-specific portions of the work.

How We Compare Contractors
License Verification
All license data is sourced from official California CSLB records and verified regularly.
Review Analysis
Customer reviews are aggregated from Google and analyzed to identify patterns in service quality.
Detailed Comparison
We analyze credentials, insurance, experience, and feedback to highlight meaningful differences.
Not all licensed contractors are created equal. While a valid license is the baseline requirement in California, contractors can vary significantly in experience, insurance coverage, and customer satisfaction.
- Experience matters: A contractor with 15+ years of experience has likely encountered and solved problems that newer contractors haven't faced yet.
- Workers' compensation protects you: If a contractor without workers' comp insurance has an employee injured on your property, you could be held liable.
- Reviews reveal patterns: Individual reviews can be misleading, but patterns across many reviews often reveal a contractor's true strengths and weaknesses.
- Bond amounts vary: A contractor's bond provides financial protection if they fail to complete work as agreed. Higher bonds offer more protection.
Taking time to compare contractors on these factors can save you from costly mistakes and help ensure your project is completed by a qualified professional.
