Consider Equinox Roofing if...
- ✓ Your project is a standard roof replacement without underlying leak issues, and you value a quick turnaround with minimal disruption to your schedule.
- ✓ You're coordinating roofing work with a solar installation and need a contractor who can meet tight external deadlines.
- ✓ You prefer frequent project updates and organized job management over deep diagnostic troubleshooting for unusual problems.
- ✓ Your roof is relatively straightforward—asphalt shingle, flat TPO, or torch-down—without complicated waterproofing needs on decks or balconies.
Consider Star Waterproofing and Roofing if...
- ✓ You have a persistent leak that previous contractors haven't solved, or you need expert diagnosis before committing to a scope of work.
- ✓ Your project involves deck or balcony waterproofing in addition to roofing, requiring specialized envelope expertise.
- ✓ You own a multi-unit property or have a complex building with multiple roof types or larger commercial-style flat areas.
- ✓ You value working with a contractor who has twice the licensed experience and has seen a wider range of complications, even if turnaround may not be as fast.
Questions to Ask Before Hiring
- → Ask Equinox how they handle projects where hidden damage is discovered mid-job, and request examples of similar complications they've resolved in their 4 years.
- → Ask Star about their process for post-completion follow-up and warranty support, given some customer reports of missed communication after project completion.
- → For either contractor, ask for references from projects matching your specific scope—whether that's a straightforward replacement or complex leak investigation.
The Bottom Line
For most standard roof replacements where speed and organized execution matter, Equinox Roofing delivers efficient, well-managed projects with strong communication. However, if you're dealing with difficult leaks, need deck or balcony waterproofing, or have a complex multi-unit property, Star Waterproofing's twice-as-long licensed history and diagnostic specialization make them the stronger choice despite some follow-up concerns. If your project is straightforward and timeline-driven, go with Equinox. If you need someone who can figure out what's actually wrong before proposing a solution, Star's deeper experience justifies the selection. Ask both for references matching your specific project type before deciding.

Frequently Asked Questions
For a straightforward reroof on a typical home without leaks or unusual conditions, Equinox's 4 years is sufficient and their track record shows reliable execution. However, if your roof is older, has a history of leaks, or you're uncertain about underlying deck condition, Star's 8 years means they've encountered more hidden problems and have developed better instincts for diagnosing what's actually wrong before tearing into it.
Star Waterproofing is the clearer choice for combined roofing and waterproofing projects, as their name and customer reviews explicitly highlight deck and balcony waterproofing expertise. Equinox focuses primarily on roofing systems and hasn't demonstrated the same specialization in horizontal waterproofing applications. Star's diagnostic skills are particularly relevant when determining whether deck leaks are affecting your roof structure.
Equinox has a consistent pattern of fast project turnaround and efficient scheduling, with multiple customers noting quick completion timelines and specific mentions of solar-ready coordination. Star's reviews emphasize thoroughness and diagnostic work rather than speed. For time-sensitive projects where the scope is clear and you need rapid execution, Equinox has the stronger track record.
Some customers noted missed follow-up communication after project completion, which could matter if you anticipate needing warranty support or have questions down the line. During your initial consultation, ask Star directly about their post-completion process and how they handle warranty callbacks. If responsive after-care is a priority for you, confirm their process in writing before signing.

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.
