Consider Los Gatos Roofing if...
- ✓ You need a conventional roof replacement, repair, or related work like gutters and ventilation, and want a contractor with deep experience diagnosing complications on older roofs
- ✓ Consistent communication throughout the project matters to you, as customers repeatedly mention being kept informed from estimate through final inspection
- ✓ You value a proven track record of clean, efficient execution without the coordination complexity of multi-vendor solar installations
- ✓ You're dealing with time-sensitive needs like storm damage where responsive scheduling and experienced problem-solving are essential
Consider GAF Energy if...
- ✓ You specifically want integrated solar roofing where photovoltaic shingles replace traditional roofing material, and you're willing to accept the longer timelines inherent to solar projects
- ✓ You have patience for the multi-phase process including permitting, utility coordination, and system activation that can extend months beyond installation completion
- ✓ You're prepared to be proactive in following up on activation and technical support, given the documented pattern of post-installation communication challenges
- ✓ You understand you're choosing a specialized product with a shorter company track record rather than a conventional roofing solution
Questions to Ask Before Hiring
- → For GAF Energy: Ask for direct contact information for post-installation support and activation coordination, and request a written timeline with specific milestones for utility approval and system activation
- → For GAF Energy: Request references specifically about their post-installation experience, not just installation quality, and ask how long customers waited for system activation
- → For Los Gatos Roofing: Ask for examples of how they've handled complications discovered during tear-off on older roofs similar to yours
- → For both: Confirm crew stability and whether the same project manager oversees your job from estimate through completion
The Bottom Line
If you need conventional roofing work, Los Gatos Roofing is the clear choice with 24 years of proven execution, consistent communication, and straightforward project delivery. Their track record shows they handle what they promise efficiently. Choose GAF Energy only if you specifically want integrated solar roofing and understand you're accepting a more complex, longer timeline with documented risk of post-installation support delays. Don't choose GAF Energy for a conventional roof replacement—that's not their focus. If solar roofing interests you but the support concerns are significant, consider a traditional roof from an experienced contractor like Los Gatos Roofing with separate solar panels installed by a dedicated solar company.

Frequently Asked Questions
No, these are fundamentally different products. Los Gatos Roofing installs conventional roofing materials with decades of proven durability. GAF Energy installs solar shingles that generate electricity—a newer technology with different warranties, maintenance needs, and a much more complex installation involving multiple contractors, permitting, and utility coordination. Choose based on whether you want solar energy generation, not just roof protection.
The six-year licensure reflects that integrated solar roofing is a newer market, not necessarily lack of capability. However, Los Gatos Roofing's 24 years means they've navigated far more roof conditions, building code changes, and unexpected complications. For conventional roofing, that experience gap is meaningful. For solar roofing specifically, your bigger concern should be GAF Energy's documented post-installation support issues.
Multiple customers report difficulty reaching the company after installation for system activation and technical support, with some experiencing lengthy delays getting their solar systems turned on and producing power. This matters because you'll likely need ongoing coordination with the utility company and troubleshooting help. If you choose GAF Energy, plan to be persistent in follow-up and get activation timelines in writing upfront.
While Los Gatos Roofing handles conventional roofing, the data doesn't specify whether they coordinate with separate solar panel installers. If you want solar capability but aren't committed to integrated solar shingles, ask Los Gatos Roofing directly about preparing the roof structure for future traditional solar panel installation—a less complex option than GAF Energy's integrated approach.

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.
