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 Able Roofing Company if...
- ✓ You value highly responsive, personalized service with direct owner involvement throughout your project and want fast call-backs when questions arise.
- ✓ Your timeline is urgent—storm damage or weather concerns—and you need a contractor known specifically for quick turnaround scheduling.
- ✓ Your project is straightforward residential roof replacement or repair and doesn't involve flat roofing, extensive structural work, or insurance claims.
- ✓ You're located closer to Petaluma and prefer working with a contractor based in your immediate area.
Consider Capstone Roofing Inc if...
- ✓ Your project involves complexity beyond standard shingle replacement: flat roof sections, significant wood damage repair, vent or gutter additions, or multi-unit property work.
- ✓ You need assistance coordinating with insurance companies or documenting claims for storm or age-related damage.
- ✓ You prioritize deep industry experience—34 years means Capstone has navigated more building code changes, material evolutions, and hidden structural issues in older Sonoma County homes.
- ✓ You prefer a highly systematized process with crews known for completing full reroofs in a single day and thorough same-day cleanup.
Questions to Ask Before Hiring
- → Ask Capstone specifically about their quality control process for larger projects, given some feedback mentioning post-installation issues on multi-unit work.
- → Ask Able whether they handle flat roof sections or more complex structural repairs if your project involves anything beyond standard pitched residential roofing.
- → Ask both contractors for references from projects completed in the past year that match your roof type, age, and any special circumstances like solar coordination or insurance claims.
- → Confirm the timeline for your specific project—ask how many days the crew will be on-site and whether completion in one day is realistic given your roof size and condition.
The Bottom Line
Both contractors are fully credentialed veterans who will complete your roof properly and on time. Choose Capstone if your project involves any complexity—flat sections, significant repairs, insurance coordination, or you simply want the contractor with the most experience diagnosing problems in older Sonoma County homes. Their 34 years and broader project range provide deeper expertise for anything beyond straightforward replacement. Choose Able if you value highly responsive, personalized service with direct owner involvement, need urgent scheduling for storm damage, or have a standard residential project where their 21 years is more than sufficient and their exceptional communication style matches your preferences.

Frequently Asked Questions
For a straightforward shingle replacement on a newer home, both have ample experience to handle it well. The gap becomes meaningful if your roof is older and may have hidden damage—Capstone's 34 years means more exposure to diagnosing rot, outdated materials, or structural issues common in Sonoma County's aging housing stock. If your home was built before 1990 or you've had previous leak issues, the deeper experience provides more diagnostic value.
Both complete projects on quoted timelines, but they approach scheduling differently. Able is specifically praised for very fast turnaround scheduling and quick response to storm-related emergencies, suggesting they may get you on the calendar sooner. Capstone completes the actual work faster—often finishing full reroofs in one day—but reviews emphasize organized process over urgent scheduling. If you need an appointment this week, call Able first.
Both have customer feedback mentioning successful coordination with solar installations. Capstone's reviews reference assistance with timing constraints and documentation, suggesting more experience navigating multi-contractor projects. Their broader project portfolio and 34 years likely mean more solar coordination experience overall. Ask both contractors directly how many solar-adjacent roof projects they've completed in the past year and whether they communicate directly with your solar installer.
The feedback indicates these concerns appeared on larger or multi-unit projects, not standard residential work where Capstone receives consistently positive reviews. If you're a homeowner with a single-family residence, this pattern is less relevant to your situation. If you're managing a duplex or larger property, ask Capstone specifically about their warranty process and what quality checks happen before the crew leaves the site.

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.
