Installing Solar Panels on Standing Seam Metal Roofs: A Guide for California Homeowners

As energy bills rise and California continues its aggressive push toward renewable energy, many homeowners are turning to solar. Michaels Sheet Metal often recommend a powerful pairing: solar panels on standing seam metal roofs.
Why? Because this combination offers superior durability, unmatched compatibility, and long-term cost savings. But there’s more to it—especially in California, where fire codes, structural requirements, and energy standards play a major role.
Let’s walk you through how we ensure your metal roof is solar-ready—and code-compliant—without compromising performance or aesthetics.
Why Standing Seam Metal Roofs Are Ideal for Solar
Unlike shingle roofs or corrugated metal, which require penetration-based mounts, standing seam roofs allow for non-penetrating clamp attachments. These specialized clamps—such as S-5!® or EcoFasten® brackets—securely attach the solar racking system without drilling into your roof, preserving its waterproof membrane and warranty.
Key Advantages:
- • No roof penetrations = no leaks or voided warranties
- • Faster solar installation = reduced labour costs
- • Cleaner appearance = low-profile clamps with concealed wiring options
- • Excellent lifespan match = metal roofs last 40–70 years, solar panels 25–30 years
California Building Codes and Fire Regulations
In California, solar installations must meet Title 24 Building Energy Efficiency Standards and California Residential Code (CRC) Section R324 for solar photovoltaic systems. These include:
- • Fire classification: Metal roofs must have a Class A fire rating, which most standing seam systems qualify for.
- • Pathway setbacks: Panels must leave 36” clearance along ridges, valleys, and hips for fire-fighter access (LA County Fire Code).
- • Structural review: Your roof must meet wind uplift resistance standards, especially in Wildland-Urban Interface (WUI) zones.
Michaels Sheet Metal ensures full compliance with local codes in Los Angeles, San Bernardino, Ventura, Orange, and surrounding counties. We coordinate with your local AHJ (Authority Having Jurisdiction) to secure all necessary permits.
Step-by-Step Solar Integration on Standing Seam Roofs
- Roof Evaluation & Structural Analysis
We begin with a full inspection of seam spacing, panel material (aluminum, Galvalume®, or steel), panel gauge (usually 24 or 26), and clip types. Our team ensures your roof can support the solar array load. - Mounting System Selection
We use clamp-on mounts designed for your specific seam profile (mechanically seamed, snap-lock, or batten cap). The clamp’s torque setting and spacing are calibrated to avoid damaging the seams. - Racking & Panel Alignment
Panels are mounted to aluminum rails secured to the seam clamps. Rails are spaced according to ASCE 7-16 wind load calculations and solar array weight distribution. - Wiring & Roof Protection
All wiring is run in UV-rated conduits or beneath panels using wire clips to minimize exposure. No fasteners touch the metal panels. - Final Inspection & Permit Closeout
We coordinate with your solar provider, city inspectors, and utility companies (like LADWP or SCE) to complete sign-offs and interconnection.
Common Technical Questions (Answered by MSM)

For any questions or concerns, get in touch with our knowledgeable staff today. We would be glad to assist you!
Contact Us TodayQ: What types of seams can clamps attach to?
A: Snap-lock and mechanically seamed panels are ideal. We evaluate the exact seam shape (e.g., bulb, double-lock, tee-seam) and choose clamps accordingly.
Q: Are there risks of galvanic corrosion?
A: Yes—if panel materials differ from mounting metals. For example, aluminum clamps on copper panels can corrode. We match metals or use isolating pads.
Q: Can solar cause thermal movement issues on metal roofs?
A: Not if properly installed. Our clamp systems are designed to allow for panel expansion and contraction across temperature ranges common in California.
Planning Tips for California Homeowners
- Get a roofing contractor involved early.
Even if your solar installer is confident, metal roofs are specialty systems. Let MSM evaluate your roof before anything is bolted down. - Ask for PE-stamped drawings.
If you’re in a seismic zone (most of CA), structural engineers may need to approve racking loads. We coordinate these submissions. - Check roof age.
Solar lasts 25+ years. If your roof is older than 10–15 years, consider re-roofing before installing panels. MSM offers standing seam roof upgrades specifically for solar compatibility.
