The Bottom Line
For most homeowners in Napa County, Stubbs Roofing is the safer choice. Their 48 years of experience translates to better diagnosis of hidden damage, proven ability to handle complications, and a long track record of follow-through. If your roof is older, has leak history, involves low-slope sections, or you simply want the confidence that comes with deep experience, Stubbs is the clear call. AGS ROOFING INC is a reasonable option if your roof is newer, the project is straightforward, and you value speed and a team customers describe as easy to work with. Get estimates from both, but unless AGS offers a significant price advantage and your project is simple, Stubbs' experience provides measurably more protection.

Frequently Asked Questions
Yes, it matters significantly for project complexity. A contractor licensed for 48 years has diagnosed thousands of roofs and encountered nearly every hidden condition, from compromised sheathing to inadequate ventilation. A one-year contractor is still building that diagnostic expertise. For a straightforward replacement on a newer roof, the gap matters less; for older roofs or storm damage, experience directly reduces risk.
Fast completion isn't inherently negative if the work is sound. Several customers noted AGS completed installations within days and were satisfied with results. However, speed can sometimes reflect a focus on straightforward projects rather than complex diagnostics. Ask AGS directly about their approach to inspecting decking, ventilation, and flashing during tear-off.
Not necessarily. Established contractors often have supplier relationships and operational efficiencies that control costs, though their experience may command higher rates for complex work. The data provided doesn't include pricing, so you'll need to request estimates from both and compare the scope of work included, not just the bottom line.
It suggests Stubbs has established workflows for navigating permitting requirements, which can save homeowners time and reduce the risk of code violations. AGS may also handle permits, but it's not highlighted in customer feedback. If your project requires permits, ask both contractors directly who manages the process and what their turnaround time typically is.

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.
