Consider Star Waterproofing and Roofing if...
- ✓ Your project involves deck waterproofing, balcony systems, or flat/low-slope roofing where moisture intrusion crosses multiple building components
- ✓ You're dealing with a persistent leak that previous contractors couldn't diagnose, and you need someone experienced in tracking water through complex pathways
- ✓ You manage a multi-unit property requiring coordination of roofing, waterproofing, and exterior envelope work across multiple buildings
- ✓ You value the additional three years of licensure for handling unexpected complications that emerge during tear-off
Consider Apollo Roofing Company if...
- ✓ Your project is a straightforward residential roof replacement where execution consistency and timeline predictability matter most
- ✓ You want structured project management with step-by-step updates, detailed option explanations, and daily worksite cleanup
- ✓ You prefer a no-pressure sales process with clear warranty information and thorough upfront inspections
- ✓ On-time or early completion is a priority, and you appreciate proactive communication about scheduling
Questions to Ask Before Hiring
- → Ask Star about their follow-up process after project completion and how they handle warranty callbacks, given occasional reports of missed follow-up
- → Ask Apollo for references on projects similar to yours, particularly if your scope involves waterproofing or multi-system moisture issues beyond standard roofing
- → Confirm with both contractors how they handle scope changes when unexpected conditions like dry rot are discovered during tear-off
- → Ask about the specific crew that will work on your project and how long they've been with the company
The Bottom Line
Choose Star Waterproofing and Roofing if your project involves waterproofing, deck or balcony integration, multi-unit properties, or difficult leak diagnosis—their eight years of dual-specialty experience provides meaningful advantages for complex moisture problems. Choose Apollo Roofing Company if you need a straightforward residential roof replacement where predictable timelines, systematic communication, and clean daily execution matter most. Both carry proper insurance and bonding, but Star's broader expertise serves complicated scopes while Apollo's structured approach excels at standard replacements. If your project falls somewhere in between, Star's additional experience and diagnostic capability provide more versatility, though you should confirm their follow-up protocols upfront.

Frequently Asked Questions
It depends on your roof type and home design. If you have a simple pitched roof with composition shingles and no deck or balcony integration, Apollo's focused approach may be sufficient. However, if your roof includes flat sections, interfaces with decks or balconies, or you've had persistent leaks, Star's diagnostic expertise and waterproofing knowledge become valuable for identifying problems standard roofers might miss.
Eight years versus five means Star has navigated 60% more building code updates, weather cycles, and complicated projects. Practically, this shows up in diagnosing hidden damage during tear-off and handling unexpected structural issues. Both are experienced contractors, but Star's additional years provide more pattern recognition when projects don't go as planned.
No, Star's reviews don't indicate high-pressure tactics. Apollo customers specifically called out the no-pressure approach, likely because it stood out to them, but that doesn't mean Star operates differently. Ask both contractors about their estimate process and how they handle decision timelines to assess fit for yourself.
It's worth addressing directly. Ask Star about their warranty callback process and how they schedule post-completion inspections. Also clarify response times for issues that arise after substantial completion. If post-project support is critical to you, get these commitments in writing and consider whether Apollo's track record of consistent communication better matches your priorities.

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.
