Frequently Asked Questions
This comparison reveals a fundamental mismatch. Los Gatos Roofing specializes in residential roofing while Therma focuses on commercial mechanical contracting and custom fabrication. If you need residential roof work, Los Gatos Roofing is the relevant choice. Therma does not appear to offer residential roofing services based on their description and customer feedback.
Therma's expertise is in HVAC duct manufacturing and specialty components for commercial facilities, not residential roof installation. The skills required for custom metal fabrication differ significantly from those needed for residential roof replacement, material selection, and homeowner project management. Their customer feedback references industrial applications, not home roofing projects.
Los Gatos Roofing's 24 years versus Therma's 9 years would be meaningful if both companies performed residential roofing. Veteran contractors typically have more experience diagnosing hidden damage in older homes and managing complications during reroofing. However, this comparison is irrelevant since Therma appears to serve only commercial clients.
Both carry workers compensation insurance and $25,000 bonds, meeting baseline requirements. However, insurance adequacy depends on whether the contractor actually performs the work you need. Los Gatos Roofing's coverage applies to residential roofing crews working on homes, while Therma's coverage appears oriented toward commercial mechanical installations.

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.
