Consider AGS ROOFING INC if...
- ✓ Your roof is relatively new or straightforward, with visible damage that doesn't require extensive diagnostic experience to assess and address.
- ✓ Speed is your primary concern and you need installation completed within days of approval, based on their track record of quick turnaround from evaluation to completion.
- ✓ You prefer working with a smaller, newer company where the crew culture emphasizes friendliness and ease of communication throughout a simple replacement project.
- ✓ You're comfortable confirming estimate delivery timelines upfront, given one customer's reported difficulty receiving their estimate promptly after the initial appointment.
Consider Performance Roofing if...
- ✓ Your roof is older and may have underlying issues that aren't immediately visible, requiring experienced diagnosis to avoid surprises mid-project or incomplete repairs.
- ✓ You need urgent repair work or leak diagnosis where three decades of troubleshooting experience directly impacts finding the actual source of water intrusion.
- ✓ You value thorough communication with photo documentation of roof conditions, helping you understand exactly what work is needed and why before committing.
- ✓ You're planning a more complex project like converting from tile to composite shingles, or want a contractor with a proven track record across hundreds of projects and repeat customers.
Questions to Ask Before Hiring
- → Ask AGS ROOFING INC for references from projects completed in the past year that involved complications discovered during tear-off, and how those situations were handled.
- → Ask Performance Roofing about current scheduling availability, since reviews mention fitting work into busy schedules, and confirm realistic timelines for your project size.
- → Ask both contractors what their process is for discovering and communicating unexpected damage once work begins, including how change orders are priced and approved.
The Bottom Line
Performance Roofing is the stronger choice for most homeowners, particularly those with older roofs, complex projects, or situations requiring diagnostic expertise. Thirty years of licensed experience translates directly to better problem-solving when hidden damage appears or leak sources aren't obvious, and their customer feedback demonstrates the thorough communication that experience enables. AGS ROOFING INC is a viable option if your project is straightforward, your roof is relatively new without likely complications, and you prioritize fast turnaround with a friendly crew. Both carry proper insurance and bonding, but experience matters significantly in roofing. If you're unsure about your roof's condition, the veteran contractor provides substantially more protection against diagnostic errors and mid-project surprises.

Frequently Asked Questions
Yes, particularly for older roofs. Three decades of experience means Performance Roofing has encountered thousands of hidden damage scenarios, unusual leak sources, and knows how different roof materials age in Napa's climate. A newer contractor may complete the installation properly but might miss underlying deck damage or misdiagnose the actual cause of a leak. For straightforward replacements on newer homes, the gap matters less.
It's a benefit for straightforward projects where speed matters, and nothing in the reviews suggests rushed or poor workmanship. However, very fast timelines can sometimes indicate less thorough diagnostic work upfront. Make sure any contractor, regardless of experience level, provides a detailed assessment of your roof deck condition and explains what preparation work will happen before new materials go on.
Performance Roofing's 30 years of experience and customer feedback about thorough explanations with photos suggest stronger diagnostic capabilities. Leak sources are often not obvious, and experienced contractors know to check flashing details, valley construction, and ventilation issues that newer contractors might overlook. If you need repair rather than full replacement, diagnostic experience becomes the primary selection factor.
One customer reported difficulty receiving an estimate after a late appointment arrival, which suggests occasional administrative gaps. This doesn't reflect on roofing quality but does mean you should confirm estimate delivery timelines upfront and follow up proactively if you don't receive it when promised. Their completed project reviews don't show similar communication issues once work begins.

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.
