Cal-Pac Roofing
Featuring SteelROCK™ Roof Products
What does it mean when we say your roof is your home's first line of defense? Simply this: the Silicon Valley sees every kind of weather and act of nature. Rain, high winds, earthquakes, wildfires — you name it, we've got it. A quality roof protects your home — and the best roof for your home is a stone-coated steel tile or shake roof from Cal-Pac Roofing.

Why is Cal-Pac the best choice? We've been doing this the longest. We introduced stone-coated steel roofing to the United States over 30 years ago. We know the technology, we know the industry, and we know the Silicon Valley.

SteelROCK™ Roof Products
Every SteelROCK panel is formed from 26-gauge Galvalume® steel and covered with natural stone granules that are embedded in a 100% acrylic resin basecoat. The panels are then finished with a clear acrylic over-glaze to seal and protect the stone granules.

SteelROCK panels are not only strong, lightweight and durable but they’ve also surpassed the industry’s highest performance tests to date. All of SteelROCK’s blended colors are enhanced with flashes of rock granules in either a dark or light accent to add a subtle beauty to the roof’s overall appearance.

The panels are backed by a lifetime limited warranty covering 120-mph winds and a Class-4 Hail impact (UL 2218) resistance rating. SteelROCK is proud to offer today’s homeowners and builders a product that will provide years of maintenance free protection and beauty.
