Consider Advanced Roofing Co Inc if...
- ✓ Your roof is older than 15 years or you suspect underlying issues like inadequate ventilation, previous poor repairs, or potential decking damage that requires experienced diagnosis during tear-off
- ✓ You value consultative guidance on materials, colors, and complementary work like gutter systems as part of the planning process
- ✓ You prioritize a contractor with decades of completed projects to reference and a long-term presence for warranty claims
- ✓ Your project involves a commercial property, winery, or non-standard residential structure where experience with diverse building types matters
Consider AGS ROOFING INC if...
- ✓ Your roof is relatively straightforward with no suspected complications, and you need the work completed on a fast timeline
- ✓ You prioritize a highly responsive, friendly crew experience and value the direct attention newer companies often provide
- ✓ You're comfortable with a contractor still building their long-term track record in exchange for competitive responsiveness
- ✓ You want to confirm estimate delivery and appointment punctuality upfront, then proceed if those initial interactions meet expectations
Questions to Ask Before Hiring
- → Ask AGS ROOFING INC for references from projects completed 6-12 months ago to verify warranty follow-through and how they handled any callbacks
- → Ask Advanced Roofing Co Inc about their current project timeline and crew availability, since veteran contractors sometimes have longer scheduling queues
- → Ask both companies what they do when tear-off reveals unexpected decking rot or structural issues, including how change orders are priced and communicated
- → Ask AGS ROOFING INC specifically about their estimate delivery process and typical turnaround time given the feedback about follow-up delays
The Bottom Line
Advanced Roofing Co Inc is the safer choice for most homeowners, particularly if your roof is older, your home has previous repair history, or you want maximum confidence in a contractor's ability to handle complications. Their 25 years of licensing provides depth that matters when the unexpected happens. AGS ROOFING INC can work well for straightforward replacements where speed and friendly service are priorities, but verify their estimate responsiveness upfront and ensure you're comfortable with a contractor still in their first year. If your project has any complexity or your roof's condition is uncertain, the experience gap tips decisively toward Advanced Roofing.

Frequently Asked Questions
Yes, particularly when problems emerge. A veteran contractor has diagnosed thousands of unexpected issues during tear-offs and knows how to solve structural problems, improper flashing, or code complications without delaying your project. A one-year contractor is still building that problem-solving database. If your roof is newer and straightforward, the gap matters less.
Not necessarily—they carry proper workers comp and bonding, and reviews consistently praise completed work quality and professionalism. However, you're taking more risk on their long-term presence for warranty issues and their ability to handle unexpected complications. Ask for recent references and confirm their plan if they encounter hidden damage.
Not automatically. Veteran contractors sometimes have better supplier relationships and more efficient crews that offset experience premiums. However, they may also command higher rates for expertise and carry longer scheduling queues. Get specific bids from both to compare actual pricing rather than assuming cost based on tenure.
It's worth addressing directly but shouldn't disqualify them outright. One customer reported delayed arrival and difficulty receiving the estimate, but multiple others describe smooth, professional experiences. Ask upfront about their estimate delivery timeline and use their responsiveness during initial contact as a gauge of how they'll communicate throughout the project.

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.
