Consider Marco Roofing if...
- ✓ You need roof replacement, repair, or leak diagnosis on an older roof where experience identifying hidden damage and matching discontinued materials matters
- ✓ Responsive communication throughout the project is a priority, particularly if you're working within insurance timelines or tight scheduling windows
- ✓ You value thorough upfront inspections and detailed estimates that align with final scope without surprise add-ons
- ✓ Your project involves tile roof repair, wood rot remediation, or plywood sheathing replacement where veteran-level troubleshooting experience provides meaningful value
Consider Power On Solar if...
- ✓ You're installing a residential solar panel system and need expertise with SunPower, Enphase, or SunVault systems including system sizing and production estimates
- ✓ You require permitting coordination and HOA approval documentation as part of a full-scope solar installation
- ✓ You're prepared to be proactive about system monitoring and potentially persistent if service issues arise after installation
- ✓ You're comparing solar contractors specifically and willing to ask direct questions about service response protocols and repair timelines based on customer feedback patterns
Questions to Ask Before Hiring
- → For Power On Solar: What is your guaranteed response time for service calls after installation, and can you provide references from customers who needed post-installation support?
- → For Power On Solar: How do you handle system monitoring, and what should I expect if panels stop communicating or production drops unexpectedly?
- → If considering solar on an older roof: Ask Marco Roofing to inspect your roof structure and remaining lifespan before solar installation, since removing and reinstalling panels for a roof replacement later adds significant cost
- → For either contractor: Request a detailed timeline with milestones and ask how they communicate if delays occur
The Bottom Line
These contractors serve entirely different needs, so your choice depends on what your home requires. If you need roofing work—replacement, repair, leak diagnosis, or tile matching—Marco Roofing's 45 years of experience, responsive communication pattern, and track record with older roofs makes it a strong choice. If you're installing solar panels, Power On Solar handles installations smoothly and works with quality equipment, but the recurring service responsiveness concerns require you to ask direct questions about post-installation support protocols and get commitments in writing. If you're considering solar on an older roof, consult Marco Roofing first to assess whether roof replacement should happen before solar installation. Don't let a solar contractor install panels on a roof with less than 10-15 years of remaining life.

Frequently Asked Questions
If your roof is older or showing wear, address it before solar installation. Removing and reinstalling solar panels to replace a roof later costs thousands in additional labor. Marco Roofing can assess remaining roof lifespan and structural integrity, while Power On Solar can design a system once roofing work is complete.
Multiple customers report difficulty reaching Power On Solar for post-installation issues and extended repair timelines when panels stop communicating or systems underperform. Solar systems require occasional troubleshooting over 20-25 years, so ask specifically about service protocols, guaranteed response times, and whether they provide direct contact information for technical support before signing a contract.
Yes, particularly for complex repairs on older roofs. Veteran contractors bring institutional knowledge for diagnosing hidden damage like wood rot, matching discontinued materials like specific clay tiles, and handling unexpected complications that emerge once old roofing is removed. Customer feedback confirms Marco Roofing applies this experience to thorough inspections and detailed scoping.
No. These are distinct trades requiring separate licenses and expertise. Complete any needed roofing work with Marco Roofing first, then schedule solar installation with Power On Solar. Coordinate timing so the new roof is complete before solar permitting begins, and ensure your roofing contractor knows solar panels will be installed so they can address any structural considerations.

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.
