Consider Bay Valley Roofing & Solar if...
- ✓ Your roof needs replacement or significant repair before or during a solar project, especially if you're dealing with storm damage, leaks, or an aging roof that won't support panel warranties
- ✓ You're installing solar shingles or integrated roofing products where the solar component is part of the roof surface itself
- ✓ You already have solar panels installed by an electrical contractor but need the roof replaced or repaired, requiring professional panel removal and reinstallation
- ✓ You need detailed roof inspection and documentation to assess whether your current roof can handle solar equipment weight and warranties
Consider Got Watts? if...
- ✓ You're installing a new solar photovoltaic system and need the electrical infrastructure, inverter setup, and utility interconnection handled correctly
- ✓ You want battery backup added to an existing solar system or designed into a new installation from the start
- ✓ Your electrical panel needs upgrading to support solar production, EV charging, or other high-load appliances like heat pumps
- ✓ You're planning multiple electrical projects (solar, EV charger, panel upgrade, HVAC) and want one contractor to coordinate the entire electrical scope and permitting process
Questions to Ask Before Hiring
- → If considering Bay Valley for solar work, ask specifically what electrical components they handle versus what gets subcontracted to a licensed electrician, and who warranties the electrical connections
- → If considering Got Watts for a solar project, ask whether your roof has been assessed for condition and load capacity, and whether they coordinate with a roofing contractor or expect you to handle that separately
- → Ask each company to clarify exactly which permits they pull and which inspections they manage for your specific project scope
- → For solar projects involving both roof and electrical work, ask each contractor who they typically coordinate with for the other trade and whether they've worked together before
The Bottom Line
You're not choosing between two competing contractors—you're identifying which trade you actually need. If your project involves roof replacement, repair, leak diagnosis, or solar shingles, contact Bay Valley Roofing & Solar. If you need solar panel electrical installation, battery backup, panel upgrades, or EV chargers, contact Got Watts. Many complete solar projects on older homes actually require both: Bay Valley to ensure the roof structure is sound and will last through the solar warranty period, followed by Got Watts to design and install the electrical system. Clarify your scope before reaching out, and don't hesitate to ask each contractor directly whether your project falls within their license and expertise.

Frequently Asked Questions
Bay Valley can handle solar shingles and roofing-integrated products completely, but standard solar panels involve significant electrical work that requires an electrical contractor license. Got Watts can handle all electrical aspects of solar panel systems but cannot perform roofing repairs or replacements. For a standard solar panel installation on a sound roof, Got Watts handles the complete project. If your roof needs work first, you'll need Bay Valley or another roofer before solar installation.
Contact Bay Valley first to assess and replace the roof, as solar panels should not be installed on a roof nearing the end of its lifespan. Most solar warranties assume a sound roof underneath, and you don't want to pay for panel removal and reinstallation in five years when the roof fails. Once the roof is solid, Got Watts can design and install the solar electrical system on the new surface.
Got Watts installs the solar panels and all associated electrical components, but they don't repair or replace roofing. Their installation includes mounting hardware attached to your existing roof structure. If your roof has issues, leaks, or is older, you should have it assessed and repaired by a roofing contractor before Got Watts begins the solar electrical installation.
Got Watts is the clear choice for battery backup additions, as this is purely electrical work involving inverter compatibility, panel capacity assessment, and electrical permits. Bay Valley's expertise is in roofing systems, not energy storage electrical integration. Customer reviews specifically mention Got Watts handling battery additions for existing solar customers.

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.
