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 Wedge Roofing if...
- ✓ Your roof involves specialty systems like flat roofing, spray foam applications, or roof coatings that require specific technical knowledge beyond standard shingle work
- ✓ You have an older roof where hidden damage is likely and you want a contractor with 44 years of experience diagnosing and addressing complications during tear-off
- ✓ Your project involves coordination with other trades (such as storm damage repairs requiring multiple contractors) or custom elements like skylight additions
- ✓ You prioritize detailed communication and careful execution over the fastest possible completion timeline
Consider Capstone Roofing Inc if...
- ✓ You need a straightforward shingle reroof completed quickly, ideally within a single day, and speed is your primary concern
- ✓ Your project has timing constraints such as approaching rain or a scheduled solar installation that requires fast turnaround
- ✓ You have a simple residential roof without flat sections, specialty coatings, or complex flashing details
- ✓ You need help with insurance documentation and coordination for a standard replacement claim
Questions to Ask Before Hiring
- → For Capstone: Ask specifically about their process for quality control on completion day, and request references from multi-unit or larger projects similar to yours if applicable
- → For both: Confirm how long their current installation crew has worked together and who will supervise your specific project from start to finish
- → Ask each company how they handle complications discovered during tear-off, including pricing for wood repair and timeline adjustments if hidden damage is found
The Bottom Line
For most homeowners, Wedge Roofing is the safer choice. Its 44-year track record, broader technical expertise across specialty systems, and consistent customer feedback without post-completion concerns outweigh Capstone's speed advantage. If you have an older roof that may hide complications, need specialty work like spray foam or roof coatings, or want maximum confidence in quality execution, Wedge's additional decade of experience translates to measurably better protection. Choose Capstone only if you need a straightforward shingle reroof completed in a single day and speed outweighs all other factors. Otherwise, schedule estimates with both but lean toward Wedge unless Capstone's timeline or pricing offers compelling reasons to accept slightly higher execution risk.

Frequently Asked Questions
For a simple shingle replacement on a newer roof, both have sufficient experience. However, Wedge's additional decade becomes meaningful if your roof is older and may hide rotted decking, complex flashing issues, or ventilation problems that require diagnosis during tear-off. Veteran contractors with 44 years have encountered more edge cases and developed better problem-solving instincts.
Wedge's reviews emphasize on-time completion within promised timeframes but don't consistently mention single-day speed. The tradeoff appears to be Wedge's focus on detail and thorough execution versus Capstone's emphasis on rapid turnaround. For straightforward projects, Capstone's speed is an advantage; for complex roofs, Wedge's measured approach may reduce post-completion issues.
The concerns appear in a smaller number of reviews and reference larger or multi-unit projects specifically. For a standard single-family reroof, Capstone's overall track record suggests reliable execution. However, if your project involves a larger home, multiple units, or complex roof geometry, ask Capstone directly for references from similar projects and inquire about their warranty and follow-up process.
Wedge Roofing has demonstrated experience across spray foam, roof coatings, and flat-roof applications based on customer feedback, while Capstone is noted for flat-roof problem-solving but doesn't show the same breadth of specialty work. If your project involves anything beyond standard shingle installation, Wedge's 44-year track record and documented specialty expertise provide more confidence.

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.
