About Our Company
Castro Valley Roots. Generations of Roofing Trust.
At Wonderlin Roofing, we’re more than a roofing company—we’re a family legacy. Grover and Larae Wonderlin started this business in 1992 with one goal: serve their neighbors with honesty, excellence, and a handshake-you-can-trust mentality. Thirty years later, that same ethos lives on through their son Matthew, trusted team leader Jorge, and office manager extraordinaire Marianne.
We’ve roofed half the homes on our street—and likely a few on yours. Our name is on every job, and we treat your home like it’s our own. No pushy sales. No cutting corners. Just high-quality roofs done right the first time.
