Consider Marco Roofing if...
- ✓ You need a contractor whose entire 45-year history is roofing-specific, particularly valuable if your roof is older and may reveal hidden damage like wood rot or plywood deterioration once work begins.
- ✓ You want workers compensation coverage in place so you're not exposed to liability if someone is injured while working on your roof.
- ✓ Consistent feedback about communication, detailed estimates, and on-time completion matters to you, especially if you're coordinating with insurance deadlines or need predictable project timelines.
- ✓ Your project includes specialty work like matching discontinued tile, skylight replacement, or coordinating gutters and downspouts alongside roofing.
Consider Clogbusters Plumbing And General Building if...
- ✓ You have a plumbing emergency and need same-day response, where Clogbusters has demonstrated capability.
- ✓ Your project is plumbing-focused rather than roofing, aligning with their core service area.
- ✓ You're willing to accept the liability risk of no workers comp on file and confirm your own homeowner's policy would cover contractor injuries.
- ✓ You can navigate potential communication inconsistencies during scheduling and estimating, as feedback suggests varied experiences in this area.
Questions to Ask Before Hiring
- → Ask Clogbusters directly about their liability coverage for roofing work and confirm in writing what happens if a worker is injured on your property—then verify with your homeowner's insurance whether you'd be exposed.
- → Ask Clogbusters how many roofing projects they've completed in the past year and request references specifically for roof work, not plumbing jobs.
- → Ask both contractors for a detailed written estimate that specifies scope, timeline, cleanup procedures, and warranty terms so you can compare what's actually included.
The Bottom Line
If you're hiring for a roofing project, Marco Roofing is the appropriate choice. With 45 years of roofing-specific experience, workers comp coverage that protects you from liability, and consistent feedback praising communication and reliability, Marco presents substantially lower risk for roof work. Clogbusters' missing workers comp is a significant concern for any project involving height and injury risk, and their mixed communication feedback combined with limited roofing specialization makes them a poor fit for roof projects despite their 25-year history in plumbing and general building. Contact Marco Roofing for your roofing needs and reserve Clogbusters for emergency plumbing situations where they've demonstrated capability.

Frequently Asked Questions
Roofing is high-risk work involving falls and injuries. Without workers comp, if someone is hurt on your roof, your homeowner's insurance may become the primary coverage, exposing you to claims that could increase your premiums or lead to lawsuits. Marco Roofing's workers comp coverage protects you from this liability.
While a general building license technically covers roofing, there's a meaningful difference between licensing authority and actual specialization. Marco Roofing's 45 years focused exclusively on roofing means deep expertise in diagnosing hidden damage, matching materials, and managing roof-specific complications. Ask Clogbusters for specific roofing project references to assess their actual experience level.
Yes, particularly because those decades represent roofing-specific experience. Older roofs often reveal hidden problems once work begins—rotted sheathing, outdated flashing, structural issues. A contractor with 45 years of roofing history has navigated these complications thousands of times and can adjust scope and pricing accurately. That experience reduces your risk of mid-project surprises.
A lower price may reflect the lack of workers comp insurance overhead, but that savings transfers liability risk directly to you. Price differences can also signal different approaches to diagnosing scope—Marco's feedback emphasizes thorough inspections and detailed bids with no surprise add-ons. Request itemized estimates from both and verify what's included before comparing bottom-line numbers.

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.
