Excellent Work - Great Communication
Consider Gramajo Roofing Inc if...
- ✓ You're installing or replacing a standard shingle roof and want a versatile contractor who can handle related work like gutters, downspouts, and skylight replacement in one project
- ✓ Your budget prioritizes competitive pricing over premium materials, and customer feedback about Gramajo's reasonable estimates compared to competitors matters to your decision
- ✓ You need a contractor who listens to concerns and explains options clearly, particularly if you're uncertain about the best approach for your specific roof
- ✓ Your project is straightforward residential work rather than a specialized metal installation, and 7 years of experience is sufficient for your scope
Consider Metal Roof Systems Inc if...
- ✓ You're specifically seeking a metal roof for fire resistance in Sonoma County's wildfire-prone environment and want a contractor who has spent 36 years mastering this single material type
- ✓ Long-term value matters more than upfront cost—you're willing to invest significantly more now for a roof that may last 40+ years based on their track record
- ✓ Your property requires expertise in metal system complexities like thermal movement, proper fastening for high winds, or specialized flashing details that come only with decades of focused experience
- ✓ You want proof of durability, and installations still looking excellent after nearly 20 years provides the confidence level you need for this major investment
Questions to Ask Before Hiring
- → Ask Gramajo for references from projects similar to yours in scope and materials, and specifically inquire about their cleanup process and jobsite management practices if your property has multiple units or requires extra care
- → Ask Metal Roof Systems for a detailed cost comparison showing the total cost of ownership over 30-40 years versus traditional roofing, including energy savings and lifespan, to justify the higher upfront investment
- → Ask both contractors how they handle unexpected discoveries like hidden water damage or structural issues, and whether their estimates include contingency amounts or require change orders
The Bottom Line
Your decision comes down to material choice, not contractor quality—both are properly licensed and insured. If you're installing a metal roof for fire resistance and long-term value in Sonoma County, Metal Roof Systems' 36 years of specialized experience justifies their involvement, especially given customer reports of installations lasting nearly two decades with excellent appearance. If you need a shingle roof, coating work, or want to bundle roofing with gutters and exterior items at competitive pricing, Gramajo's 7 years of versatile experience serves that need well—just establish clear cleanup expectations in writing before work begins, particularly for multi-unit properties.

Frequently Asked Questions
This isn't an apples-to-apples comparison because the materials themselves differ dramatically in cost and lifespan. Metal roofing typically costs 2-3 times more than shingles regardless of installer, but can last 40-60 years versus 20-30 for shingles. Metal Roof Systems' 36 years means they've refined installation techniques that prevent the fastener failures and thermal movement issues that plague poorly installed metal roofs. If you're committed to metal roofing for fire protection or longevity, their experience level directly protects your investment.
The data doesn't show Gramajo performing metal roof installations—their work centers on shingles, coatings, and general roofing. While many general roofers can technically install metal, the specialized knowledge about thermal expansion, proper fastener spacing, and seam integrity that comes from 36 years of exclusive focus is substantial. If you want a metal roof in a wildfire zone, the specialist's experience matters significantly for long-term performance.
The cleanup concern came from a larger apartment complex project, not typical residential work. This suggests their protocols for high-traffic or multi-unit properties may need reinforcement rather than indicating systematic problems. If you're hiring them for a single-family home, address cleanup expectations explicitly in your contract and schedule a walkthrough before final payment. For apartment buildings or commercial properties, ask specifically how they'll manage debris and access.
The available data shows exclusive focus on metal roof installations with no mention of gutters, repairs, coatings, or other roofing types. Their 36-year specialization is their strength for metal work, but if you need gutter installation, skylight replacement, or future repairs on a shingle portion of your roof, you'd likely need a different contractor. Ask them directly whether they handle related exterior work or only metal roofing.

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.
