Customer Reviews
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.

I wanted to wait for a few days of steady rain before I reviewed the roof maintenance. They were professional when they came out and they did not leave a mess. And so far we do not have any leaks and ...
Consider Capstone Roofing Inc if...
- ✓ Your roof replacement needs to coordinate with other major projects like solar panel installation or insurance claim timelines, where Capstone's experience managing documentation and scheduling dependencies is frequently mentioned
- ✓ You're replacing an older roof that may involve hidden damage or structural issues where 34 years of diagnostic experience provides additional confidence in identifying problems before they become costly surprises
- ✓ You prefer a streamlined process with detailed upfront estimates and value the efficiency of single-day completion for full reroofs, which multiple customers specifically highlighted
Consider Northbay Roofing & Gutters Inc if...
- ✓ You're dealing with an active leak or emergency situation and need same-day or weekend service, where Northbay's documented track record of emergency response gives you faster access to repairs
- ✓ You want real-time visibility into your project through photo updates and text communication rather than waiting until completion to see the work
- ✓ Punctuality is a priority and you appreciate crews arriving ahead of schedule rather than on time, a pattern repeatedly mentioned in Northbay's feedback
Questions to Ask Before Hiring
- → Ask Capstone about their typical timeline for emergency leak calls versus scheduled replacements, since their reviews emphasize planned projects more than urgent response
- → Ask Northbay how their communication approach works on larger full-replacement projects compared to the smaller repairs where photo updates are most referenced
- → For either company, request references from projects similar in scope and age to your roof, particularly if your home dates back several decades
The Bottom Line
Both contractors offer veteran-level expertise with proper insurance and bonding, so you're choosing between two solid options rather than one clearly superior choice. Capstone's 34 years of experience makes them the safer bet for complex projects involving older roofs, insurance coordination, or situations where diagnosing hidden damage is critical. Northbay is the better choice if you need emergency service, want real-time photo updates, or value punctuality and faster-than-expected completion. For a standard residential roof replacement on a newer home, either will serve you well—let your timeline urgency and communication preferences make the call.

Frequently Asked Questions
For straightforward shingle replacements on newer homes, the gap matters less. But for older Sonoma County homes where you might encounter deteriorated sheathing, outdated ventilation, or code compliance issues, Capstone's 34 years means they've diagnosed and solved those problems hundreds more times. That said, Northbay's 22 years still qualifies as veteran-tier experience—this isn't a comparison between seasoned and new.
Both complete work quickly, but their scheduling approaches differ. Capstone's reviews emphasize organized project timelines coordinated around specific deadlines like incoming weather or solar installations. Northbay's feedback highlights arriving ahead of schedule and faster-than-estimated completion. If you're calling this week about next week's rain, Northbay's emergency responsiveness gives you better odds of immediate availability.
This is a clear difference between the two. Northbay customers specifically mention receiving photo and text updates during repairs, showing you what they're finding and fixing in real time. Capstone's reviews focus on communication during estimating and scheduling phases, with less mention of mid-project updates. Ask Capstone directly about their communication cadence if ongoing visibility matters to you.
The $25,000 bond provides identical baseline protection if either company fails to complete contracted work. However, both also carry workers compensation insurance, which is actually more important for protecting you from liability if someone gets injured on your property. The real financial protection difference comes from experience reducing the likelihood of costly mistakes, where Capstone's additional 12 years provides a statistical edge.

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.
