I call these guys in a pinch and they always come through. I have a 105 year old house that was poorly maintained before I took it on. I need them!

Consider Alpha Roofing if...
- ✓ You're doing a straightforward roof replacement on a newer home with no anticipated complications and want modern communication tools like drone progress videos.
- ✓ You value highly responsive, detailed explanations during the estimate phase and appreciate a tech-forward approach to project updates.
- ✓ Your project timeline is flexible enough that if unexpected issues arise, you're comfortable working with a newer contractor still building their problem-solving track record.
- ✓ You've met with the owner and feel confident in their professionalism, and the lower experience level is offset by proper insurance and your own due diligence.
Consider Astro Roofing Inc if...
- ✓ Your roof is older or you suspect underlying issues like dry rot, flashing problems, or structural concerns that require diagnostic experience to identify and price accurately.
- ✓ You want a contractor with an 11-year track record who has navigated hundreds of projects and can draw on extensive problem-solving history.
- ✓ You're planning tile roof work or specialty repairs where material-specific experience matters for long-term performance.
- ✓ You value the stability of an established business that will likely be around in 5-10 years if warranty issues arise or you need follow-up service.
Questions to Ask Before Hiring
- → Ask Alpha Roofing for references from projects completed in their first year that involved unexpected complications, and how those were handled and priced.
- → Ask Astro Roofing whether they use similar documentation practices like progress photos or video, and how they keep clients updated during multi-day projects.
- → Confirm with both contractors who specifically will be doing the work and how long their current crew has worked together.
- → Ask both companies about their warranty terms and what happens if you need service in 5 years—how each ensures business continuity.
The Bottom Line
For most homeowners, Astro Roofing's 11 years of experience is the deciding factor—especially if your roof is older, you suspect hidden damage, or you're working with specialty materials like tile. That decade of licensed work means better problem diagnosis, more accurate estimates when complications arise, and a stable business likely to honor warranties years from now. Alpha Roofing is a legitimate option if your project is straightforward, you've thoroughly checked their recent references, and you value their modern communication approach with drone updates. But if you're choosing a contractor to trust with a significant investment on an older home, Astro's established track record provides substantially more protection against surprises and better assurance of long-term support.

Frequently Asked Questions
Not necessarily—Alpha is properly licensed, insured, and bonded, and reviews show organized, professional work. The concern is limited experience diagnosing hidden problems like concealed water damage or structural issues that only become apparent once old roofing is removed. A newer contractor may not price these contingencies as accurately, leading to change orders or disputes mid-project.
If Alpha's bid is significantly lower, ask why—it may reflect less contingency padding because they haven't encountered as many surprises, which could mean change orders later. Astro's 11 years means more accurate pricing on complex jobs and a longer track record for warranty support. For straightforward projects, the experience gap matters less; for older roofs or tile work, it matters significantly.
An established contractor has diagnosed hundreds of roofs and knows what problems to look for during inspection—hidden rot, inadequate ventilation, flashing failures. They've also built supplier relationships for better material pricing and have repeat crews who work efficiently together. Most importantly, they have a business track record suggesting they'll be around to honor warranties years from now.
It depends on your project. For a simple reroof on a newer home with no complications, a newer contractor with proper insurance can do fine work, and Alpha's reviews suggest they're detail-oriented. For older homes, complex repairs, or specialty materials like tile, the lack of a long track record is a meaningful risk. You're essentially betting on their ability to handle problems they may not have encountered yet.

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.
