Cathedral Sunrooms bring a sense of openness and natural light to your home with their soaring vaulted ceilings and dramatic glass walls. This popular design creates a spacious, elegant atmosphere that connects indoor living with the beauty of the outdoors.
Since 1983, Petkus Brothers has built custom Cathedral Sunrooms for homeowners across Northern California. Each project is tailored for lasting comfort, energy efficiency, and seamless integration with your home’s style.
