Questions to Ask Before Hiring
- → If planning both roofing and solar work, ask Wedge Roofing what roof preparation solar installers typically require and confirm your roof structure can support panel weight
- → If planning both projects, ask Michael & Sun Solar about minimum roof condition requirements and whether your current roof will last through the solar system's warranty period
- → Ask whichever contractor you're considering about project timeline and how current permitting wait times in Sonoma County might affect your schedule
The Bottom Line
This comparison only makes sense if you're unclear whether you need roofing work or solar installation. If your roof needs repair or replacement, hire Wedge Roofing. If you need solar panels or battery backup installed on an already-sound roof, hire Michael & Sun Solar. Both companies are properly credentialed and well-reviewed in their respective specialties. If you're planning both projects, complete all roofing work first with Wedge Roofing to ensure your roof will last through the 25-year lifespan of solar equipment, then hire Michael & Sun Solar for the solar installation. Do not attempt to coordinate these as a single project, as they require different expertise, licensing, and sequencing.

Frequently Asked Questions
No, these companies serve completely different needs. Wedge Roofing does not install solar systems, and Michael & Sun Solar does not perform roofing work. If you need both services, you'll hire them separately, with roofing completed first to ensure your roof is structurally sound and has sufficient remaining lifespan to match your solar warranty period, typically 25 years.
If your roof is more than 10-15 years old or showing wear, address roofing first with a contractor like Wedge Roofing. Removing and reinstalling solar panels to replace a roof later is expensive and disruptive. Solar installers like Michael & Sun Solar need a structurally sound roof with at least 20-25 years of remaining life to match system warranties.
Wedge Roofing's 44 years is irrelevant for solar work since they don't offer that service. Michael & Sun Solar's 14 years is substantial experience in the solar industry, which has only matured in California over the past two decades. The experience comparison only matters if you're actually choosing between roofing contractors.
Properly installed solar systems should not damage a sound roof, but installation requires penetrating the roofing material to anchor racking systems. This is why roof condition matters before solar installation. If you have roofing concerns, get a roofing assessment from a contractor like Wedge Roofing before proceeding with solar quotes to avoid discovering problems mid-installation.

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.
