Robert did a great job getting here on time and checking out my roofing issues
Save A Lot Solar
They did my panels a few years ago and I could not be happier with the service, and the product.
Locally run, great people, skilled at designing a small system that the big players couldn’t be bothered with. On time and on budget with no surprises.
Jon and team were great to work with.
Consider Sierra Roofing And Solar if...
- ✓ Your roof is older than 10 years or you've had previous leaks, and you need one contractor to assess roof condition, make necessary repairs, and then install solar without coordination headaches between trades.
- ✓ You're dealing with an active leak or emergency situation and want solar added after the roof is stabilized by someone who already knows your structure.
- ✓ Your project involves complex roofing materials like tile or standing seam metal that require specialized knowledge to properly integrate solar mounting.
- ✓ You value having 22 years of problem-solving experience on job sites where hidden damage or complications often emerge during installation.
Consider Save A Lot Solar if...
- ✓ Your roof is relatively new and in confirmed good condition, so you need deep solar expertise rather than roofing diagnostics.
- ✓ You want high owner involvement in the design phase with someone who will personally walk you through equipment options, system sizing, and technical decisions.
- ✓ Competitive solar pricing is a priority and you're comparing multiple quotes specifically for the solar installation itself.
- ✓ Your property has challenging permitting requirements or you're working with newer solar technology like Enphase battery systems where specialized solar focus provides an advantage.
Questions to Ask Before Hiring
- → Ask Sierra Roofing And Solar: If roof repairs are needed before solar installation, how do you price that work separately, and will the same crew handle both phases?
- → Ask Save A Lot Solar: If your roof inspection reveals issues during solar prep, who handles those repairs and how does that affect timeline and coordination?
- → Ask both: How long will scheduling take given current workload, and what's your typical timeline from contract signing to system activation?
- → Ask both: What equipment brands do you recommend for my specific situation, and how do warranty terms differ between options?
The Bottom Line
Choose Sierra Roofing And Solar if your roof is older, has a history of issues, or you want one veteran contractor handling both roof assessment and solar installation without coordinating multiple companies. Their 22 years of roofing experience means they'll catch problems before panels go up and can fix them in-house. Choose Save A Lot Solar if your roof is newer and sound, you want high owner involvement in system design, and competitive solar pricing is your priority. Their 14 years of exclusive solar focus translates to deep equipment knowledge and efficient installations when roofing isn't a variable. Both are properly insured and communicate well, so your decision comes down to whether roofing expertise or solar specialization matters more for your specific situation.

Frequently Asked Questions
It matters primarily if roof condition is uncertain. Those extra years give Sierra pattern recognition for spotting structural issues, water damage, or remaining roof lifespan problems before solar goes on. If you've had a recent roof inspection confirming everything is sound, Save A Lot's 14 years of focused solar experience may be more relevant to equipment selection and system optimization.
Save A Lot coordinates with roofing contractors when repairs are necessary, but they don't perform roofing work in-house. This means you're relying on their network and managing an additional relationship if issues surface. Ask them directly how they handle this scenario and whether their pricing accounts for coordination delays.
The data doesn't provide direct pricing comparisons for solar installations between these companies. Sierra's customers describe overall pricing as fair and competitive, while Save A Lot's reviews specifically emphasize below-competitor pricing for solar. Get itemized quotes from both and compare the solar installation line items separately from any roofing work.
Save A Lot shows no scheduling concerns in customer feedback, while Sierra's reviews note that scheduling may require advance planning during busy or rainy periods. If you're on a tight timeline, ask both companies directly about current lead times and confirm in writing when work can begin and finish.

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.
