The CornerStone Roofing Story:

CornerStone Roofing is a family owned and operated business based in San Diego County, Southern California. It was founded in 1988 by Neville and Berta Graaff.

Neville immigarated to the United States (from South Africa) in 1978. He started in the Industry in 1979 as the Controller/Public Works estimator of Lee Roofing of Costa Mesa. After ten years with Lee Roofing he started his own business.

For the past 22 years, we have served Individual Homeowners, Property Managers, Real Estate Agents, Insurance Adjusters and friends in the Contructiion Industry with the intention of honoring the Cornerstone name.

Our Moto: "We don't cut corners", is an expression of that  intention.

Nathan has worked with his dad since he was twelve and as an adult, has become an accomplished professional in his own right.

He is a certified Eagle-Solar Energy Installer and has also been certified by the (T.R.I.) Tile Roofing Institute.

In keeping with the Cornerstone tradition, he (and Heather, his wife) have established their own brand of the same name and is licensed in California. The following is a link to their Cornerstone Roofing company:
