Consider Thor Contracting Corporation if...
- ✓ Your project is straightforward—a standard shingle replacement or repair without complex architectural features or multiple related systems that need coordination.
- ✓ Timeline is your priority and you need work completed quickly, potentially while you're away, with minimal disruption to your schedule.
- ✓ Budget is a primary concern and you value competitive pricing with options to reduce costs while meeting basic requirements.
- ✓ You prefer a hands-off approach once the scope is agreed upon and trust a professional crew to execute without needing frequent updates.
Consider Jorge Lopez Roofing Inc if...
- ✓ Your roof is older or has potential for hidden damage that requires experienced diagnosis beyond surface-level assessment.
- ✓ Your project involves complexity like flat roofing, skylights, or coordination with related work such as gutters, siding, or attic insulation.
- ✓ You value detailed communication throughout the process, including photo documentation and regular progress updates to stay informed.
- ✓ You want high owner involvement and a contractor who has navigated nine years of Bay Area permitting, weather challenges, and diverse roofing systems.
Questions to Ask Before Hiring
- → Ask Thor how they handle unexpected issues like hidden rot or structural damage discovered during tear-off, given their shorter track record with complex scenarios.
- → Ask Jorge Lopez about their typical project timeline compared to competitors, since reviews emphasize thoroughness but don't highlight the fast completion Thor customers mention.
- → Request references from both contractors for projects similar in scope and complexity to yours, particularly if your roof has unique features.
- → Clarify each contractor's approach to project updates and communication frequency to match your preference for involvement level.
The Bottom Line
Jorge Lopez Roofing is the stronger choice for most homeowners due to more than twice the licensed experience, broader service capabilities, and superior project communication practices with regular updates and photo documentation. The additional years matter particularly for older roofs, complex projects, or situations where you want high owner involvement and detailed progress tracking. However, if your project is straightforward, timeline is critical, and you prefer a faster-moving operation with competitive pricing and minimal communication once the scope is set, Thor Contracting delivers efficient execution with a solid track record. For complex roofing systems, related work coordination, or peace of mind from deeper experience, Jorge Lopez justifies the choice.

Frequently Asked Questions
For uncomplicated shingle-to-shingle replacements on newer homes, the gap matters less. However, Jorge Lopez's additional years become valuable if your roof is older, has multiple layers to remove, or reveals surprises like inadequate ventilation or deck damage during tear-off. Nine years means more repetitions diagnosing and solving these common but unpredictable issues.
Thor Contracting has stronger feedback emphasizing fast turnaround and jobs completed within tight windows. Customers specifically mention crews finishing quickly while they were away. Jorge Lopez customers emphasize thoroughness and communication but don't highlight speed as a distinguishing factor, suggesting a more methodical pace.
Jorge Lopez customers consistently mention regular email updates with progress photos and detailed explanations of work being performed—a documentation-heavy approach. Thor customers describe clear upfront walkthroughs and straightforward pricing but don't emphasize ongoing updates during execution, suggesting you'll have less frequent contact once work begins.
If you need related work like skylight installation, gutter coordination, siding repairs, or attic insulation handled by the same contractor, Jorge Lopez explicitly offers these services. Thor's feedback focuses on core roofing work without mention of these ancillary services, so you'd likely need separate contractors if your project scope expands.

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.
