All On Electric And Solar
Quality Work. Polite and friendly staff
Consider Century Roof And Solar if...
- ✓ Your solar project involves an older roof that may need evaluation or repair before panel installation, benefiting from Century's documented experience identifying and addressing dry rot, structural issues, and necessary upgrades during integrated projects.
- ✓ You want verifiable evidence of how a contractor handles project coordination, communicates options, and manages cleanup, which Century's customer feedback provides in detail across tile, composition, and solar work.
- ✓ Your project combines roofing work with solar installation, where Century's 30 years coordinating multiple trades and managing complex timelines is directly relevant to avoiding delays and ensuring proper sequencing.
- ✓ You value transparency during bidding and detailed explanations of warranty options, which multiple customers specifically mention as part of Century's process.
Consider All On Electric And Solar if...
- ✓ Your project is purely electrical work related to solar (panel hookup, main panel upgrade, battery integration) where All On Electric And Solar's electrical specialization is directly applicable, assuming their unlicensed work matches their credentials.
- ✓ You're willing to request and verify references directly since no public customer feedback exists to validate their installation quality, crew professionalism, or project management approach.
- ✓ You prioritize electrical expertise over roofing knowledge and your roof is newer with no concerns about structural integrity, flashing compatibility, or penetration planning that would benefit from roofing-first experience.
- ✓ You're prepared to ask detailed questions about their solar installation process, roof assessment procedures, and warranty terms without customer feedback to guide your expectations.
Questions to Ask Before Hiring
- → Ask All On Electric And Solar for at least three recent references from residential solar projects similar to yours, and contact them to verify crew quality, timeline accuracy, and how complications were handled.
- → Ask All On Electric And Solar how they assess roof condition before solar installation and what happens if they discover structural issues, dry rot, or flashing problems during the project—clarify whether they subcontract roofing work or halt the project.
- → Ask both companies for detailed written warranties covering workmanship, roof penetrations, and panel performance, and clarify what happens if roof leaks develop at mounting points within the first five years.
- → Ask Century about their pricing structure compared to electrically-focused solar contractors, and whether their roofing expertise adds value for your specific roof age and condition.
The Bottom Line
Century Roof And Solar is the safer choice for most homeowners needing solar installation this week. Their 30 years of licensed experience, extensive customer feedback detailing thorough project coordination and workmanship, and documented history managing integrated roofing-solar projects provide verifiable evidence of how they'll handle your job. All On Electric And Solar holds proper credentials and relevant electrical expertise, but without customer reviews to confirm installation quality or service approach, you're hiring based entirely on licensing rather than proven performance. If you're considering All On Electric And Solar, invest time verifying references and confirming their solar installation process addresses roof integrity—otherwise, Century's documented track record justifies their selection for residential solar work.

Frequently Asked Questions
Yes, significantly if your roof is over 10 years old. Solar installations require multiple roof penetrations for mounting hardware, and contractors with roofing experience are better equipped to identify underlying issues like compromised decking or inadequate flashing before creating new leak points. Century's documented history includes evaluating roofs during solar bids and coordinating necessary repairs, while All On Electric And Solar's approach to roof assessment is unverified.
This could reflect limited residential work, reliance on commercial projects, or minimal online presence—but it means you cannot verify their installation quality, communication style, or problem-solving approach through independent customer experiences. Before hiring, request multiple references and contact them directly to confirm the company's actual track record matches their licensing credentials.
Electrical expertise matters for main panel upgrades, battery integration, and complex hookups, but solar installations are equally dependent on proper roof penetration, waterproofing, and structural assessment. Century's customer feedback shows experience coordinating electrical work within solar projects, while All On Electric And Solar's electrical background is relevant but unverified in practice. Ask both companies how they handle the roofing aspects of solar work.
Only if you can verify that All On Electric And Solar's pricing is actually lower—and if their references confirm comparable workmanship and project management. Century's pricing is noted as sometimes higher but connected to detailed evaluations and thorough installations. Without All On Electric And Solar's customer feedback, you cannot assess whether any cost savings come with tradeoffs in communication, cleanup, or warranty support.

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.
