Mortensen Roofing & Gutters
Mortensen Roofing roofed our house 35 years ago and it still stand strong. That is until a branch came and chipped a cement tile - they were great and helping me procure a new one a tiny bit different...
Very reasonably priced. Quality workmanship. Timely and consistent with deign.

Consider Mortensen Roofing & Gutters if...
- ✓ Your roof is cement tile and you want a contractor with specific, proven expertise in this material system that requires specialized knowledge for proper installation and repair
- ✓ You value a decades-long track record over cutting-edge communication practices, particularly if your home is older and may have hidden structural issues that experience helps identify
- ✓ You prefer working with a veteran contractor whose owner involvement is documented and whose long-term workmanship you can verify through customers from years past
- ✓ You're in Concord or immediate surroundings where Mortensen has deep local knowledge and established supplier relationships
Consider Precise Roofing Inc if...
- ✓ You prioritize frequent project updates and communication throughout the work, which recent customers consistently highlight as a Precise Roofing strength
- ✓ Your project involves insurance coordination for storm damage, where Precise has demonstrated experience working with adjusters
- ✓ You need work completed quickly and value their pattern of finishing ahead of schedule
- ✓ Your project involves diverse materials or specialty work like skylight installation or historic restoration where their stated broader service range may be relevant
Questions to Ask Before Hiring
- → Ask Precise Roofing for references from their earliest projects (2 years ago) to verify how that initial work has held up and whether those customers would hire them again
- → Ask Precise Roofing about the background of their crew leads: how many years of roofing experience do the people supervising your job actually have, separate from the company's licensure date
- → Ask Mortensen about their specific process for cement tile versus other roofing materials if your project involves something outside their noted specialty
- → Ask both contractors how they handle unexpected complications like rotted decking or structural issues discovered during tear-off, including cost implications
The Bottom Line
For most homeowners, particularly those with older homes, cement tile roofs, or complex repair needs, Mortensen Roofing & Gutters is the lower-risk choice. Their 36-year track record provides verifiable long-term performance and proven ability to handle complications that experience teaches you to anticipate. Precise Roofing Inc earns strong recent reviews for communication and efficiency, but two years in business simply hasn't provided enough time to demonstrate durability or build the diagnostic expertise that comes from decades of varied projects. If you have a straightforward roof replacement on a newer home and value frequent communication, Precise may serve you well—but ask about crew experience beyond the company's licensure date. For most situations, Mortensen's veteran status offers substantially more verified capability.

Frequently Asked Questions
Not necessarily—the crew and owner may have roofing experience predating the company's license. However, it does mean less verifiable track record as a business entity. Ask directly about the crew's experience levels and request references you can contact. A newer company hasn't had time to demonstrate long-term workmanship durability the way Mortensen has with decades-old installations still performing.
Customer reviews specifically mention cement tile work, but the company is licensed for general roofing. Ask Mortensen directly about their experience with your specific roofing material and request references for similar projects. Their 36 years suggests broad exposure, but you want confirmation they're as comfortable with your material as they clearly are with tile.
Mortensen's 36 years provides substantially more exposure to diagnosing concealed damage in aging roof systems. While Precise reviews mention thorough inspections identifying underlying issues, experience matters significantly when distinguishing between cosmetic problems and structural concerns. For homes built before 1990, Mortensen's veteran status offers more proven diagnostic capability.
Both carry the same $25,000 bond, so there's no difference in this financial protection. The bond provides recourse if either contractor abandons your project or fails to meet contract terms. Both also carry workers compensation insurance, protecting you from liability if a worker is injured on your property.

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.
