Consider Apollo Roofing Company if...
- ✓ Your home needs roof repair or replacement, whether addressing active leaks, aging shingles past their warranty period, or preparing for a future solar installation that requires a sound roof structure first
- ✓ You value detailed explanations of roofing materials, warranty options, and step-by-step project updates from estimate through completion
- ✓ You want a contractor experienced in identifying hidden damage like dry rot during roof work and explaining cost implications clearly
- ✓ Your project involves related components like skylights, gutters, or waterproofing that benefit from roofing-specific expertise
Consider Calpro Solar if...
- ✓ Your home needs solar panel installation or battery backup systems to reduce energy costs or increase grid independence
- ✓ You're comparing solar providers and prefer a no-pressure consultation approach backed by decades of industry experience
- ✓ You value a contractor who has navigated multiple solar technology generations and understands evolving incentive programs and local permitting
- ✓ Post-installation service responsiveness matters to you, particularly for addressing system performance issues or questions as they arise
Questions to Ask Before Hiring
- → If installing solar, ask Apollo Roofing how they coordinate with solar contractors and whether roof warranties remain valid after panel installation
- → If installing solar, ask Calpro about roof condition requirements and whether they provide roof assessments or coordinate with roofing contractors
- → Ask Calpro Solar for references from installations completed 5-10 years ago to verify long-term system performance and service responsiveness
- → If you need both services, ask each company about timing coordination and how solar mounting affects roof warranties
The Bottom Line
These contractors serve completely different needs, so your choice depends entirely on your project type. If you need roof repair, replacement, leak troubleshooting, or related waterproofing work, Apollo Roofing is your option with solid 5-year roofing-specific experience and strong marks for communication and inspection detail. If you're installing solar panels or battery backup systems, Calpro Solar brings 37 years of solar industry experience with consistent feedback around low-pressure sales and responsive service. If you need both a roof replacement and solar installation, plan to hire Apollo first to ensure a sound roof structure, then bring in Calpro for solar work afterward, coordinating timing and warranty implications between both companies.

Frequently Asked Questions
If your roof has less than 10-15 years of remaining life, most solar installers recommend replacing it first to avoid the significant cost of removing and reinstalling panels later. Apollo Roofing can assess your roof's condition and remaining lifespan. Calpro Solar should also evaluate roof condition during their consultation, but they specialize in solar installation rather than roofing repairs.
Not in this comparison. Apollo Roofing specializes in roofing work but doesn't install solar systems, while Calpro Solar handles solar installations but isn't a roofing contractor. You would need to hire them sequentially or coordinate between them if both projects are needed.
No. Calpro's extensive experience is in solar installations, not roofing. For roof repairs, replacements, or leak troubleshooting, Apollo Roofing's 5 years of roofing-specific experience is directly relevant, while Calpro would not handle those projects at all.
It depends on your existing roof warranty terms and how panels are mounted. This is a critical question to ask both your current roofing warranty provider and Calpro Solar before installation. If Apollo Roofing completes a new roof first, ask them specifically how solar mounting affects their warranty coverage.

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.
