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.

Consider Capstone Roofing Inc if...
- ✓ Your roof replacement needs to happen quickly, and you value a documented track record of one-day completions with crews that arrive as scheduled and complete thorough cleanup.
- ✓ You want visibility into the contractor's communication style before signing, and multiple customer accounts describe Capstone providing detailed estimates and staying responsive throughout the project.
- ✓ You're coordinating your roof work with other home projects like solar installation or working around weather constraints, as reviews mention Capstone accommodating these timing needs.
- ✓ You need assistance with insurance-related documentation, which past customers have specifically mentioned receiving from Capstone.
Consider A+ Quality Roofing if...
- ✓ You've received a compelling estimate or personal referral from A+ Quality Roofing that addresses your specific project needs, and you're comfortable evaluating a contractor without extensive public feedback to reference.
- ✓ You prioritize the Glen Ellen service area and prefer working with a contractor based closer to your property in that specific location.
- ✓ You're willing to conduct your own due diligence through direct references and detailed conversations to assess crew reliability and project management, since public reviews don't provide that visibility for A+ Quality Roofing.
Questions to Ask Before Hiring
- → Ask A+ Quality Roofing for at least three recent references for projects similar to yours in size and scope, and follow up on crew punctuality, cleanup quality, and communication during the work.
- → Ask both contractors how they handle unexpected discoveries like damaged wood or inadequate ventilation once the old roof is removed, including how pricing changes are communicated.
- → Ask about their timeline for your specific project and what factors might delay completion, especially given Capstone's pattern of single-day installations for standard residential work.
- → Ask A+ Quality Roofing how long their current crew has been working together and who will be on-site supervising the installation.
The Bottom Line
For most homeowners needing a roof replacement this week, Capstone Roofing Inc offers a more transparent choice. Their 34 years of licensing, combined with consistent customer feedback describing organized processes, one-day completions, and thorough cleanup, gives you a clear picture of what to expect. The 15-year experience advantage matters when crews encounter rotted wood or ventilation problems once your old roof is removed. A+ Quality Roofing meets all regulatory requirements and has substantial experience, but without customer feedback documenting their execution, you're making a credentials-only decision. If A+ Quality provides compelling references and a detailed proposal that addresses your concerns, their 19 years qualifies them as capable—but Capstone's documented track record reduces uncertainty for homeowners who need confidence in their contractor choice this week.

Frequently Asked Questions
Yes, particularly for older homes in Sonoma County. Fifteen additional years means more experience diagnosing hidden damage once the old roof is removed, working with different material generations, and adapting to code changes. Reviews confirm Capstone regularly handles wood repair and problem-solving on aging roofs, not just straightforward installations.
This could reflect several factors: the company may operate primarily through word-of-mouth referrals, customers may not be leaving online reviews, or business volume may be lower. You should ask A+ Quality directly for references and how many projects they've completed in the past year to understand their current operational tempo.
The feedback suggests these issues appeared on larger or multi-unit projects rather than standard residential reroofs. If you're planning a straightforward single-family roof replacement, the pattern of successful one-day completions is more relevant. For complex or commercial work, ask Capstone specifically about their quality control process for larger projects.
Both serve Sonoma County, so location shouldn't significantly affect availability or service quality. Santa Rosa is more centralized, while Glen Ellen serves the eastern valley. Choose based on the contractor's documented capabilities rather than the seven-mile difference in their listed offices.

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.
