Key Differences

The defining difference is experience: Modern Method Roofing has held its license for 31 years compared to AGS ROOFING INC's 1 year. Three decades means Modern Method has navigated thousands of projects, encountered rare structural issues, worked through permit complications, and handled unusual building materials that a newer contractor simply hasn't seen yet. This matters most when removing old roofing reveals unexpected damage or when local code requirements create complications. Customer feedback patterns also diverge meaningfully. AGS customers consistently praise speed and friendliness, with roofs completed in days and a smooth crew experience. Modern Method customers highlight repeat business across multiple properties and describe professional crews with reliable cleanup, but several mention inconsistent follow-through on callbacks and post-job corrections. AGS has one reported estimating delay, while Modern Method shows a pattern of mixed communication reliability. For straightforward replacements on newer homes, AGS delivers fast, friendly service. For older properties, complex repairs, or projects requiring diagnostic expertise, Modern Method's veteran status provides substantially more depth.

Consider AGS ROOFING INC if...

  • Your roof is relatively new (under 20 years), the damage is visible and straightforward, and you don't anticipate hidden structural issues that require experienced diagnosis.
  • Speed is a priority and you value a fast turnaround from estimate to completed installation, with customers reporting roof work finished within days.
  • You prefer working with a smaller, newer company where the crew is described as exceptionally friendly and easy to communicate with throughout the project.
  • You're comfortable with a contractor who has a shorter track record and are willing to ask detailed questions about how they'd handle unexpected complications.

Consider Modern Method Roofing if...

  • Your home is older and the roof may have underlying issues like damaged decking, fascia rot, or structural concerns that benefit from a contractor who has seen thousands of similar situations over three decades.
  • You need specialized work beyond basic replacement, such as flat roof repairs, storm damage assessment, fascia board replacement, or sun tunnel installation, all referenced in Modern Method's project history.
  • You value a contractor with established longevity and repeat customers who have used them across multiple properties, suggesting sustained business relationships.
  • You can confirm communication expectations upfront given mixed feedback on follow-through, but want the depth of experience that comes with 31 years in business.

Questions to Ask Before Hiring

  • Ask AGS ROOFING INC for references from projects similar in age and complexity to your home, and inquire how they handle unexpected discoveries like rotted decking or structural issues once the old roof is removed.
  • Ask Modern Method Roofing about their process for post-job follow-up and how they ensure callbacks are handled promptly, given mixed feedback on this point.
  • For both companies, confirm the timeline for receiving your written estimate and clarify appointment windows to avoid scheduling frustrations.
  • Ask both contractors to walk the attic and inspect from below before estimating, ensuring they identify potential hidden issues rather than quoting based solely on exterior inspection.

The Bottom Line

For most homeowners, Modern Method Roofing's 31 years of experience provides meaningfully better protection against the complications that often emerge during roof work, especially on older homes. The ability to diagnose hidden damage, navigate permit requirements, and handle specialized repairs comes from decades of accumulated problem-solving that a 1-year contractor cannot match. However, if your home is newer, the damage is straightforward and visible, and speed matters significantly, AGS ROOFING INC delivers fast, friendly service with proper insurance and bonding. Confirm communication expectations with Modern Method given mixed follow-through feedback, but their veteran status makes them the safer choice for complex projects or older properties.

Frequently Asked Questions

It depends on your home's age and condition. For a newer home with visible, straightforward damage, the gap matters less. For homes over 30 years old, experience becomes critical because removing old roofing often reveals hidden rot, inadequate ventilation, or structural issues that a 1-year contractor hasn't encountered enough to diagnose and correct properly. Three decades means Modern Method has handled complications AGS simply hasn't seen yet.

Speed and friendliness are valuable, but they don't replace diagnostic expertise when problems arise. If your project is straightforward, AGS's quick turnaround is appealing. If there's any chance of hidden damage or you need specialized repair work beyond basic replacement, Modern Method's 31 years of problem-solving experience provides substantially more protection against costly mistakes or incomplete solutions.

Some customers report smooth communication while others describe difficulty getting callbacks for post-job corrections or additional site visits. This isn't a universal problem but suggests inconsistency. Address this upfront by asking about their callback process and getting a direct contact for post-installation issues. Given their 31 years and repeat customer base, the core work quality appears solid, but communication discipline varies.

Not necessarily, but it requires more due diligence from you. AGS carries proper insurance and bonding, and customers praise their completed work. The risk is encountering a complication the team hasn't handled before. Mitigate this by asking detailed questions about their process for unexpected issues, confirming they pull permits properly, and checking references from projects on homes similar in age to yours.

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.
