I cannot recommend Arturo and the team at Galvan Roofing enough! I have hired them for several roofing projects now, and they have consistently delivered exceptional work. They are the definition of p...

Capstone Roofing Inc
These guys are amazing. They replaced the roof in one day and price was very competitive. The crew was so nice. I recommend them and would hire them again.
When I needed a new roof recently, I first turned to Capstone Roofing for an estimate. My husband and I had a new roof installed on our former home in 2001 by Capstone. Our experiences with the owner,...
The Capstone did a great job and finished in just one day! They even did some nice follow up for us by cleaning up our rain gutters.
Consider Galvan Roofing & Gutters if...
- ✓ Your roof is older or shows signs of underlying issues like sagging, water stains, or visible rot that may require careful diagnosis beyond surface replacement
- ✓ You value detailed explanations of what's being done and why, with direct owner communication throughout the project timeline
- ✓ Your project involves discovering and addressing hidden problems like ventilation deficiencies or structural wood damage as work progresses
- ✓ You prefer a contractor who explicitly avoids shortcuts even if completion takes more than one day
Consider Capstone Roofing Inc if...
- ✓ You need a straightforward roof replacement completed quickly, ideally within a single day to minimize weather exposure or meet a tight deadline
- ✓ Your project involves coordination challenges like upcoming rain, solar panel installation timing, or insurance claim documentation where veteran experience helps
- ✓ You're dealing with flat roof issues where Capstone's specific expertise is mentioned in customer feedback
- ✓ You value a streamlined, organized process on a standard residential reroof where efficiency matters more than discovering every potential ancillary issue
Questions to Ask Before Hiring
- → Ask Capstone specifically about their quality control process on completion and what their warranty covers for post-installation issues, given reviews mentioning leaks on larger projects
- → Ask Galvan for references from projects completed within the last year that involved discovering hidden damage during roof replacement
- → Ask both contractors how they handle unexpected structural issues found during tear-off and whether timeline estimates account for addressing those problems
- → Ask Capstone whether the owner or a crew lead will be the primary contact during your project, and how communication works if issues arise mid-job
The Bottom Line
If your roof is older, shows signs of underlying problems, or you value thorough communication and discovering issues before they worsen, Galvan Roofing's methodical approach and high owner involvement make them the better choice despite less experience. If you need a straightforward replacement completed quickly, have timing constraints, or are dealing with specialized needs like flat roofing where veteran knowledge matters, Capstone's 34 years of experience offers valuable expertise—but ask directly about their quality control process and warranty given the post-installation concerns on some larger projects. For most standard residential reroofs, Galvan's detail-oriented reputation outweighs the experience gap.

Frequently Asked Questions
For a straightforward reroof on a newer home without complications, the experience gap matters less—both contractors handle standard replacements competently. The veteran experience becomes more valuable on older roofs where decades of pattern recognition help anticipate hidden damage, or on projects requiring specialized knowledge like flat roofing. If your roof is under 20 years old with no visible issues, Galvan's 8 years is sufficient experience.
The pattern appears specifically on larger or multi-unit projects rather than standard single-family homes, but it's worth addressing directly. Ask Capstone what happened in those situations, how they resolved them, and what their warranty process looks like if problems emerge after completion. Also confirm whether your project size matches their typical residential work or pushes into the commercial-scale range where those issues appeared.
Likely yes for comparable projects, though the difference may only be a day or two for standard residential work. Galvan's approach prioritizes thoroughness over speed, which means extra time addressing issues like proper ventilation or discovered dry rot. If weather is closing in or you have a hard deadline, confirm Galvan's realistic timeline upfront and consider whether Capstone's efficiency better matches your constraints.
Both serve the broader Sonoma County area, so location shouldn't significantly impact availability or service quality for most homeowners. The more relevant consideration is their respective approaches: Galvan's detail-oriented communication style versus Capstone's efficient, organized process. Choose based on which working style fits your project complexity and personal preferences rather than the 15-mile distance between Windsor and Santa Rosa.

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.
