Consider ARS Roofing & Gutters if...
- ✓ Your roof is older or you suspect underlying issues like dry rot or inadequate ventilation that require experienced diagnosis during tear-off and replacement
- ✓ You value detailed upfront inspections and clear explanations, including honest assessments about whether full replacement is necessary or maintenance will suffice
- ✓ Consistent jobsite cleanup, punctuality, and professionalism are priorities, especially if you're home during the work or have close neighbors
- ✓ You need coordination with insurance inspections, solar installations, or commercial roofing projects where experience managing complexity matters
Consider Gramajo Roofing Inc if...
- ✓ You've received higher estimates elsewhere and want a contractor known for competitive pricing who will listen carefully to your specific concerns and preferences
- ✓ Your project is straightforward residential work—shingle replacement, gutter installation, downspout upgrades—without unusual complexity or structural unknowns
- ✓ You're comfortable with a shorter track record in exchange for potentially better pricing and a contractor who reviewers describe as attentive to requests
- ✓ You can be present during the work to confirm cleanup standards and address any jobsite concerns directly as they arise
Questions to Ask Before Hiring
- → Ask Gramajo specifically about their approach to jobsite cleanup on residential properties and whether the crew foreperson will conduct a walkthrough with you before leaving each day
- → Request references from ARS for projects similar in age and complexity to your home, particularly if you have an older roof or suspect hidden damage
- → Ask both contractors how they handle unexpected discoveries during tear-off, including pricing for rot repair, ventilation upgrades, or structural reinforcement
- → Confirm whether either contractor will coordinate directly with your insurance adjuster if this is a claim-related repair or inspection-driven replacement
The Bottom Line
For most homeowners, ARS Roofing & Gutters is the stronger choice. The 22-year licensing history, consistent feedback on communication and jobsite professionalism, and documented experience with complex projects—older roofs, insurance inspections, solar coordination—provide meaningful advantages for the majority of residential roofing situations. Gramajo Roofing Inc offers competitive pricing and attentive service, making them worth considering if budget is your top priority and your project is straightforward, but be explicit about cleanup expectations and request recent residential references. If your roof is older, you value hands-off reliability, or you need coordination with insurance or solar, ARS's veteran track record justifies any price difference.

Frequently Asked Questions
It matters most if your roof is older or if there's any chance of hidden damage. A contractor with 22 years has seen hundreds more tear-offs and is better positioned to diagnose rot, inadequate ventilation, or structural issues mid-project without surprise change orders. For a newer roof on a well-maintained home, the gap matters less, though ARS's consistency on communication and cleanup still shows across all project types.
Multiple reviews mention Gramajo's pricing as reasonable compared to other bids, suggesting competitive rates. The tradeoff appears in operational consistency—one larger project had cleanup and conduct complaints, indicating possible variability in crew management. If you're budget-conscious and can oversee the work closely, Gramajo may offer value; if you need hands-off reliability, ARS's track record is stronger.
Not necessarily, but clarify expectations upfront. The complaint came from a multi-unit apartment project, which involves more complexity and visibility than a single-family home. Ask Gramajo directly about their cleanup protocol, whether the same crew handles residential versus commercial work, and if they'll do a final walkthrough with you. If they address it proactively, it may have been an isolated issue.
ARS has specific customer mentions of coordinating roofing ahead of solar, suggesting familiarity with the sequencing, structural load considerations, and ensuring the roof warranty aligns with solar timelines. Gramajo doesn't have documented experience in this area based on available reviews. If solar coordination is part of your project, ask ARS about their process and whether they work directly with solar installers.

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.
