Solar installation.

Installation, removal & restoration

Over time, solar panels can lose efficiency due to weather, debris, or electrical issues. CS1 installs new systems, coordinates removal and re-installation around roof replacements, and restores solar-integrated roofs when something’s not working right — addressing faulty mounts, flashing and panel damage to restore performance and prevent costly energy losses.

Solar only pays for itself while it produces, and production depends on the roof underneath as much as the panels on top. Because CS1 is both a certified roofing contractor and a solar installer, we can diagnose problems other contractors miss — a leak blamed on panels that is really failed flashing, or lost output caused by mounts shifting with the roof deck. One company accountable for the whole assembly means faster answers and no finger-pointing between trades.

Our solar services

• New installations. Rooftop and ground-mount solar for multifamily, commercial and residential properties — with utility interconnection coordination and incentive guidance.
• Removal & re-install for re-roofs. Coordinated with your panel provider so warranties stay intact through the re-roof. One schedule, one contract, no gap between trades.
• Leak & storm repair. We locate and repair active leaks around solar mounts, flashing, or roof penetrations — minimizing disruption to your system.
• Shingle & underlayment restoration. We remove damaged shingles, inspect your decking, and restore the layers beneath solar equipment for a watertight seal.
• Solar mount flashing repair. Faulty flashing is a common issue. We re-seal and reinforce these areas to protect against future water intrusion.

Why solar roof restoration may be needed

Even high-quality solar roofing systems can develop issues over time. Harsh weather, movement in the roof deck, or aging materials can cause leaks, loose mounts, or flashing failures. CS1 specializes in diagnosing and restoring solar-integrated roofs — resealing key points, repairing surfaces, and ensuring your solar investment remains protected, efficient, and code-compliant.

Frequently asked questions

Can you replace a roof that has solar panels on it?
Yes. We coordinate removal, safe storage and re-installation with your panel provider so every warranty stays intact through the re-roof — one schedule, one contract, no gap between trades.

Why is my solar roof leaking?
Faulty mount flashing is the most common cause. Harsh weather, roof deck movement or aging materials can loosen mounts and open penetrations. We locate the intrusion point, re-seal and reinforce it.

Will repairs disrupt my solar production?
We plan repairs to minimize disruption to your system, and most restoration work is completed with the array offline for hours, not days.
