Excellent quality work. Crew was respectful & cleaned area every day before leaving. Upon start found quite a bit of dry rot & gave a very reasonable quote to replace. Would highly recommend.

Consider Mortensen Roofing & Gutters if...
- ✓ Your roof is cement tile and you want a contractor with deep material-specific experience rather than a generalist approach
- ✓ You're prioritizing long-term roof performance over the next 20-30 years and value a contractor whose past installations are still holding up decades later
- ✓ Your project is straightforward leak repair or tile replacement without complications like structural damage or multi-trade coordination
- ✓ You prefer working with a contractor whose 36-year track record suggests stability and proven methods over time
Consider Dependable Roofing Inc if...
- ✓ Your roof has challenging conditions like steep slopes, flat sections, or a mix of materials that require broader technical capability
- ✓ You're facing storm damage or emergency repairs and need a crew accustomed to urgent response and quick turnaround
- ✓ Your project involves related carpentry work such as dry rot repair, roof deck replacement, or skylight installation that benefits from coordinated trade skills
- ✓ You want detailed attention to components like flashing, vents, and drainage systems, which reviews specifically highlight as Dependable strengths
Questions to Ask Before Hiring
- → Ask Mortensen how many cement tile roofs they've installed over 36 years and request references from installations done 15-20 years ago to verify longevity claims
- → Ask Dependable about crew composition and how they handle projects requiring both roofing and carpentry skills, particularly if your roof has potential dry rot or deck damage
- → For both, ask about their approach to diagnosing hidden damage during roof inspections and what typically drives cost overruns once work begins
- → Ask which crew will be assigned to your project and how long that specific team has worked together, since owner involvement is high for both but execution depends on crew experience
The Bottom Line
For most homeowners, Dependable Roofing Inc offers the better fit this week due to broader project capability, explicit emergency response experience, and integrated carpentry skills that reduce coordination risk if inspections reveal hidden damage. Their 18 years is sufficient veteran-level experience for reliable execution. Choose Mortensen if your project is cement tile-specific, you're not facing urgency, and you place premium value on a contractor whose installations have documented 20-30 year performance records. Both are solid choices with full insurance and bonding, but Dependable's range of completed project types suggests they're prepared for whatever your roof reveals once work begins, which matters when you need to choose quickly and move forward with confidence.

Frequently Asked Questions
For straightforward residential re-roofing with common materials, both contractors have sufficient experience to execute well. Mortensen's advantage becomes meaningful if you're working with cement tile or prioritizing a roof that will last 30+ years, where their pattern recognition from decades of callbacks and warranty work informs better material choices. For most composition shingle replacements, the experience gap matters less than crew quality and scheduling availability.
Dependable's reviews specifically mention storm damage response and emergency repairs as part of their regular workflow, suggesting systems for urgent scheduling. Mortensen's feedback focuses more on planned projects and ongoing maintenance relationships. If you're calling mid-storm with water coming in, Dependable appears better positioned for rapid response based on the project types customers describe.
Dependable's reviews explicitly mention dry rot repairs and roof deck work as integrated services, indicating crews with carpentry skills beyond roofing. Mortensen's feedback doesn't reference structural repairs, suggesting they focus on roofing-specific work. For projects where you expect or discover wood damage, Dependable offers coordinated capability rather than requiring a separate carpentry contractor.
Both receive consistent feedback about fair and reasonable pricing, with Dependable also described as competitive. Neither appears to compete on low-cost bidding, and both emphasize clear estimates. The pricing difference will likely come from project scope rather than company philosophy—ask both for itemized bids that separate roofing labor from any structural repairs so you can compare accurately.

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.
