Our Name Says It All: Tres Generaciones.
Three generations. One family. One craft, perfected over 45 years on the rooftops of Southern California.
This is our story.
A Craft Passed Down, Father to Son to Grandson
Every family has something it passes down. In ours, it’s roofing.
Our story begins in the 1970s, when our grandfather entered the roofing trade at a quality roofing company in Southern California. He learned fast, worked hard, and excelled — mastering the craft rooftop by rooftop, year after year. Roofing wasn’t just his job; it became his life’s work.
As he grew older, he did what fathers in the trades have always done: he passed it on. He taught his son every aspect of the craft — shingles, tile, flat roofing, metal, and everything in between. His son took that foundation and built on it, spending more than 30 years mastering roofing systems and earning a reputation for excellence in his field.
Then came the grandson. Brought to job sites at a young age, he grew up surrounded by skilled roofing professionals — watching, learning, and working alongside his grandfather and uncle. The trade was in his blood. But he saw something more: the chance to bring three generations of knowledge together under one family name. He earned his California contractor’s license, worked relentlessly, and founded the company you see today.
That company is 3G Tres Generaciones Roofing Co. — established in 2018, built on 45+ years of inherited expertise, and driven by a simple promise: integrity and exceptional quality on every roof we touch.

— Owner & Third-Generation Roofer
“Roofing is a great profession in a world full of talented tradesmen and engineers. I was fortunate to be born into a roofing family full of top-class professionals. Being around roofing was first-hand nature to me — I've had these skilled craftsmen around me all my life, and it became evident that roofing was going to be my strong side in life. I decided to take it to another level and start our family business, incorporating three generations of roofing experience.”
