Very easy to set up the work by phone.

Consider Ridgeline Roofing Co if...
- ✓ Your roof is older or has unique features (flat sections, multiple roof planes, ventilation issues) where Ridgeline's 41 years of diagnostic experience and documented problem-solving approach would help identify hidden damage or long-term performance improvements beyond basic replacement.
- ✓ You want predictable communication and transparency, as customer feedback consistently describes regular scheduling updates, detailed estimates explaining scope, and responsiveness when decisions arise mid-project.
- ✓ Jobsite cleanliness and crew professionalism matter to you, especially if your home is occupied during work, since reviews repeatedly cite daily cleanup and courteous behavior.
- ✓ You need related work like gutter installation, solar prep, or ongoing maintenance contracts, which Ridgeline has documented experience coordinating.
Consider A+ Quality Roofing if...
- ✓ You have existing relationship or direct referral to A+ Quality Roofing that provides the customer experience validation missing from public reviews, and can speak to specific projects similar to yours they've completed recently.
- ✓ You prefer working with a Glen Ellen-based contractor for proximity reasons and are willing to conduct thorough reference checks yourself to compensate for limited public feedback.
- ✓ Their quote is significantly more competitive and you're comfortable performing extra due diligence by visiting active jobsites and speaking with recent customers they provide as references.
Questions to Ask Before Hiring
- → For A+ Quality Roofing: Ask for at least three recent references from projects completed in the last 12 months similar to yours, and inquire specifically about their communication process, how they handled unexpected issues, and jobsite management.
- → For A+ Quality Roofing: Ask how long their current crew has been together and request to visit an active jobsite to observe work practices and cleanup standards firsthand.
- → For both: Confirm warranty terms in writing, including coverage duration for workmanship versus materials, and ask who handles service calls if issues arise after completion.
The Bottom Line
Ridgeline Roofing Co is the lower-risk choice for most homeowners who need to decide this week. Their 41 years of licensed experience, documented communication practices, and consistent customer feedback describing crew professionalism and thorough inspections give you a clear picture of what to expect during your project. A+ Quality Roofing has proper credentials and substantial time in business, but limited public validation of how they actually perform means you'd be making a decision without verifiable evidence of their process, communication, or problem-solving. If A+ Quality quotes significantly lower, invest time visiting their active jobsites and speaking with multiple recent references before signing. Otherwise, Ridgeline's transparent track record makes them the straightforward choice.

Frequently Asked Questions
Yes, particularly for Sonoma County homes. Ridgeline's 41 years means experience with older construction methods, previous code cycles, and diagnosing hidden issues common in the region's housing stock. On straightforward projects the gap may matter less, but if your roof reveals unexpected dry rot, inadequate ventilation, or structural concerns during tearoff, deeper experience helps with solutions that prevent callbacks.
This could reflect various business models—they may focus on commercial work, rely entirely on repeat customers and direct referrals, or simply not encourage online reviews. The data doesn't answer this, which is exactly why you should ask them directly how many residential roofs they completed in the past year and request multiple recent references you can contact.
Yes, in practical ways beyond insurance. Longer operation means more exposure to problem scenarios and developed systems for handling them. Ridgeline's reviews describe structured processes and owner involvement, suggesting established protocols that reduce miscommunication and forgotten details. A+ Quality may have similar systems, but without customer feedback confirming it, you're taking that on faith.
Not without understanding what you're comparing. Ridgeline's reviews mention thorough inspections and identifying improvements beyond basic replacement, which could mean higher quotes that address underlying problems versus cheaper quotes that defer them. Get itemized estimates from both, then ask A+ Quality's references whether their final cost matched the estimate and if any surprise issues came up that weren't anticipated.

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.
