Consider Gramajo Roofing Inc if...
- ✓ You need a straightforward roof replacement, shingle installation, or gutter work without solar panel involvement, and want competitive pricing from a contractor with proven residential experience.
- ✓ Your project is a single-family home or smaller-scale work where Gramajo's 7 years of experience is more than sufficient for standard roofing challenges.
- ✓ Budget is a primary concern and you've received higher quotes elsewhere, as customers specifically mention Gramajo's reasonable pricing compared to other estimates.
- ✓ You want a responsive contractor who listens to concerns and explains options, but plan to discuss cleanup protocols and jobsite conduct expectations clearly before work begins.
Consider Sun America Solar and Roofing Co if...
- ✓ You're installing solar panels or need work on an existing solar system, where Sun America's 36 years of specialized experience directly addresses technical complexity and integration challenges.
- ✓ Your roof is steel or another specialized material that requires specific expertise, as Sun America has documented capability with systems other contractors cannot accommodate.
- ✓ You need diagnostic work or troubleshooting on a solar installation done by another company, where their deep technical knowledge and problem-solving track record provide clear value.
- ✓ You value consistent communication and high owner involvement throughout a technically complex project, as customer feedback emphasizes responsive service and thorough explanations over multiple decades of operation.
Questions to Ask Before Hiring
- → For Gramajo: Ask for references from recent residential projects similar in scope to yours, and specifically discuss jobsite cleanup protocols, crew conduct expectations, and daily site management procedures.
- → For Sun America: If you're considering them for roofing without solar, ask how their pricing compares to traditional roofers and whether their solar specialization affects availability for non-solar roof work.
- → For both: Request detailed written estimates that specify materials, timeline, cleanup responsibilities, and payment schedule to ensure clear expectations regardless of which contractor you choose.
The Bottom Line
This decision comes down to your actual project needs. If you're installing solar panels or have a specialized roof like steel, Sun America Solar's 36 years of focused expertise makes them the obvious choice—their technical knowledge and proven problem-solving capability directly address your project's complexity. For traditional roofing work without solar considerations, Gramajo Roofing offers 7 years of solid residential experience at competitive pricing, though you should address cleanup expectations clearly upfront given mixed feedback on one larger project. Don't hire the solar specialist for basic shingle work just because they have more years, and don't hire the traditional roofer if your project involves solar integration they're not equipped to handle.

Frequently Asked Questions
For a straightforward shingle roof on a standard home, Gramajo's 7 years provides sufficient experience to handle the work competently. Sun America's additional decades matter most when dealing with solar integration, complex roof materials like steel, or troubleshooting technical system issues. If your project is traditional roofing without specialty requirements, the experience gap is less significant than pricing and availability.
Yes, their description and reviews confirm they perform full roof replacements including work completed ahead of schedule. However, their three decades of specialization in solar may mean their pricing reflects premium expertise you don't need for basic roofing. Ask them directly how their rates compare for non-solar work and whether roofing-only projects fit their current scheduling priorities.
One review described cleanup and conduct concerns on an apartment complex project, which suggests potential challenges on larger or multi-unit properties. For a single-family home, this may be less relevant, but you should explicitly discuss daily cleanup expectations, crew supervision, and jobsite management in your contract. Ask for references from recent projects similar in size and type to yours.
Yes, significantly. If solar is in your 5-10 year plan, having Sun America handle the roof now means they'll already know your roof structure, materials, and installation details when you're ready for panels. This avoids potential warranty complications and ensures the roofing work anticipates future solar loads and mounting requirements from the start.

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.
