Solar Integration with Roofing

While roofing is at the heart of what we do, many El Cajon homeowners also consider solar panels when upgrading their roof. Because Gen819 is both a licensed roofer and solar installer, we can integrate panels seamlessly with your new or existing roof. This ensures that your roof’s warranty remains intact, your solar system performs efficiently, and your home gains long-term value.

Roofing Systems We Install In El Cajon

• Metal Roofing: A long-lasting option that performs exceptionally well in El Cajon’s hot, dry climate. Metal reflects heat to keep interiors cooler, requires little maintenance, and can last up to 70 years.

• Tile Roofing: Popular throughout Southern California, tile roofs are both beautiful and durable. They handle high heat, resist pests, and often last for generations when properly maintained.

• CeDUR® Synthetic Shake: Offering the charm of cedar shakes without the risks, CeDUR® is lightweight, Class A fire-rated, and resistant to rot, insects, and warping—making it a safe and low-maintenance choice.

• Single-Ply Membranes (TPO, PVC, EPDM): These high-performance systems are widely used on commercial and flat roofs. They’re flexible, energy-efficient, and provide outstanding waterproofing protection, making them a smart investment for businesses and institutions.
