Frequently Asked Questions
No, these contractors specialize in different trades. Master Roofing handles only roofing work, while Valley Plumbing handles only plumbing systems. You'll need to hire them separately if you have projects in both areas. Neither company's licensing covers the other's specialty work.
Both are highly experienced, but the difference matters within their respective trades. Valley Plumbing's 43 years means exposure to older plumbing systems and legacy installations you won't find in newer homes. Master Roofing's 17 years provides substantial roofing expertise, particularly valuable for diagnosing hidden damage on older roofs. Both tenures represent deep trade knowledge.
Valley Plumbing's reviews specifically mention same-day and holiday emergency plumbing service, which is critical for issues like burst pipes or water heater failures. Master Roofing's reviews reference storm-related urgent repairs, suggesting responsiveness to weather damage. The answer depends on whether your emergency is plumbing or roofing related.
Master Roofing is based in Oakland but serves Alameda County and nearby East Bay communities. Valley Plumbing operates from Pleasanton covering the Tri-Valley area and neighboring communities. Both serve broader regions beyond their home base, though you should confirm service availability for your specific address, especially if you're at the edge of their territories.

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.
