Consider TSP Roofing and Solar if...
- ✓ You're planning solar panel installation now or within the next few years and want one contractor to handle roof preparation, installation, and electrical integration without coordination delays between separate trades.
- ✓ Your project involves troubleshooting existing solar systems alongside roof repairs, such as diagnosing leaks around panel mounts or replacing inverters while addressing underlying roof issues.
- ✓ You value direct owner involvement throughout the project and prefer a smaller operation where the person estimating your job stays engaged through completion.
- ✓ You need quick turnaround on straightforward projects like leak repairs or gutter installation, where TSP's track record shows efficient scheduling and fast completion times.
Consider Apollo Roofing Company if...
- ✓ Your project is roofing-only with no solar component, and you want a contractor whose entire 5-year track record focuses on roof diagnostics, replacements, and repairs without divided attention across multiple trades.
- ✓ You have an older roof where unexpected conditions like dry rot or structural issues are likely, and you want the deeper experience base that comes with two additional years of licensure handling complex replacements.
- ✓ You prefer a structured project management approach with dedicated managers providing step-by-step updates and detailed explanations of material options, warranties, and scope changes.
- ✓ Your project includes specialty components like skylight replacements or complex waterproofing where Apollo's roofing-specific focus provides more relevant experience.
Questions to Ask Before Hiring
- → Ask TSP how they sequence roofing and solar work if you're doing both, and whether roof warranties are affected by solar panel installation or future solar additions.
- → Ask Apollo whether they regularly work with solar contractors if you might add panels later, and how they handle flashing and penetrations to accommodate future solar work.
- → Ask both contractors for references from projects similar to yours in age and complexity, particularly if your roof is over 20 years old or has multiple layers.
- → Ask about their warranty coverage for both labor and materials, and what conditions or future modifications might void that protection.
The Bottom Line
If your project includes solar installation—now or likely within five years—TSP Roofing and Solar is the clearer choice, eliminating coordination hassles between separate contractors and ensuring your roof work integrates properly with electrical and solar components. For roofing-only projects, particularly on older homes where hidden damage and complications are likely, Apollo Roofing Company's 5 years of focused roofing experience and structured project management provide meaningful advantages in diagnosing issues and handling unexpected conditions. Both contractors carry proper insurance and bonding, and both receive strong marks for communication and professionalism, so your decision should center on project scope and the value you place on specialized roofing depth versus integrated solar capability.

Frequently Asked Questions
Three years of licensure represents growing but not extensive experience, which matters most on older roofs with hidden damage or unusual configurations. For straightforward re-roofs or newer homes, the gap is less significant. If your roof is over 25 years old or has had multiple repairs, Apollo's additional two years of experience diagnosing complications provides more depth. Ask TSP for references from projects matching your roof's age and condition.
TSP handles standalone roofing projects and receives strong reviews for roof repairs and installations without solar components. However, if you're certain you won't add solar in the foreseeable future, Apollo's exclusive roofing focus and longer track record offer more relevant experience. The advantage shifts to TSP if there's any possibility of solar within your roof's warranty period, as they can coordinate both from the start.
Most roofing contractors will work around future solar plans if you communicate that upfront, but coordination between separate companies adds complexity, scheduling delays, and potential warranty disputes if leaks develop near panel mounts. Ask Apollo directly about their experience working with solar installers and how they handle flashing and structural prep for future panels. TSP eliminates this coordination issue entirely by handling both trades.
Two additional years means Apollo has handled roughly 40-60% more projects, encountering more edge cases like unusual leak sources, structural deficiencies, or problematic previous repairs. This experience gap matters most when diagnosing non-obvious problems or managing unexpected complications mid-project. For straightforward replacements on homes built after 2000, the difference is less pronounced, but for complex repairs or older homes, deeper experience helps avoid costly surprises.

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.
