Clean Roofing
Problem solvers! Luis Cuello and Rodrigo and Rolando Alva worked very hard to sort out a leak situation we had. Very professional. I would recommend them for any roofing work you have.
Roof was done reasonably efficiently given inspection delays from the city. PJ was very knowledgeable and helpful with the scoping. Rodrigo was a good project manager that communicated frequently. ...
The team did a great job installing a metal roof, and they spend some time to clean things up at the end of each days.
Consider Bay 101 Roofing if...
- ✓ Your roof is older (20+ years) or has a history of leak issues that previous contractors struggled to diagnose, where Bay 101's 18 years of troubleshooting experience becomes valuable
- ✓ You need emergency repairs during bad weather and want a contractor with a track record of responsive service during storms
- ✓ Your project involves multi-unit buildings or commercial-residential hybrids, which Bay 101 has documented experience handling
- ✓ You prioritize working with a veteran contractor who's seen multiple market cycles and material evolutions
Consider Clean Roofing if...
- ✓ You're planning solar installation in the next few years and want roofing work coordinated with that timeline, where Clean Roofing's solar company connection offers streamlined planning
- ✓ You're interested in specialty materials like metal roofing or Tesla solar roof products, which appear specifically in Clean Roofing's project history
- ✓ You value frequent project updates and daily cleanup protocols, which reviewers consistently mention for Clean Roofing
- ✓ Your roof is relatively straightforward (standard residential pitch, common materials) where 8 years of experience is entirely sufficient
Questions to Ask Before Hiring
- → Ask Bay 101 about their diagnostic process for identifying hidden damage during tear-off and how change orders are communicated if substrate issues are found
- → Ask Clean Roofing about their relationship with the sister solar company and whether solar prep work is included in standard roofing quotes or quoted separately
- → For either company, confirm warranty terms on workmanship and whether they handle warranty service directly or subcontract it
- → Ask both contractors how long their current crew has worked together and what percentage of work is done by employees versus subcontractors
The Bottom Line
Bay 101 Roofing holds a clear experience advantage with 18 years of licensure versus Clean Roofing's 8, which matters most if your roof presents diagnostic challenges, hidden complications, or you simply want the deepest bench of problem-solving experience. For straightforward residential reroofs, both are qualified, but if you're planning solar installation or want specialty materials like metal or Tesla roofs, Clean Roofing's solar coordination and documented work with these products offers specific value. Get quotes from both, but if pricing is comparable, Bay 101's veteran status provides more insurance against unexpected complications that only reveal themselves once shingles come off.

Frequently Asked Questions
For a straightforward residential reroof on a newer home with predictable substrate conditions, the gap matters less—both companies are fully qualified. But if your roof is older, has multiple layers, or you've had recurring leak issues no one has solved, Bay 101's extra decade of diagnostic experience becomes practically valuable. More years means more exposure to unusual failure patterns and hidden complications.
No, Clean Roofing is a dedicated roofing contractor, not a solar company. They have a sister solar business, which means they coordinate well on solar-prep roofing and understand installation requirements, but their core expertise is roofing. This connection is an advantage if solar is in your future, but doesn't indicate they're inexperienced at standalone roofing projects.
Bay 101's reviews emphasize responsiveness and flexibility, particularly during urgent situations like storm damage or persistent leaks. Clean Roofing's reviews highlight structured communication with frequent updates and organized project management. Both deliver professional work; Bay 101 skews toward adaptability and diagnostic skill, while Clean Roofing emphasizes process consistency and coordination.
Not automatically. Get quotes from both and compare scope, materials, and warranty terms alongside price. If quotes are similar, Bay 101's additional experience provides more value. If Clean Roofing is meaningfully less expensive for identical scope and materials, their 8 years is still solid for most residential projects. The experience premium makes sense primarily for complex or problem roofs.

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.
