Every California Slate tile is a singular work of nature, offering natural color variations, rich textures, and unique character that synthetic imitations simply cannot replicate. Our real slate provides an unparalleled depth and richness, ensuring a roof of genuine distinction.


Superior, Generations-Long Lifespan:
A California Slate roof is truly a one-time investment, designed to endure for 75 to over 150 years when properly installed. This exceptional longevity far surpasses the typical 20-50 year lifespan of composite alternatives, offering homeowners enduring peace of mind.


Natural Fire Resistance:
Inherently non-combustible, California Slate provides top-tier Class A fire protection for your home. Unlike composite options that may contain meltable plastics or rubber, our natural stone offers robust and reliable safety.

As 100% natural stone, California Slate is quarried with minimal processing and is fully recyclable. Choosing our slate is an inherently eco-friendly decision, contributing to a reduced environmental footprint compared to petrochemical-based composite materials.


Unrivaled Prestige & Value:
Installing a California Slate roof significantly increases your home's value, especially within luxury and historic markets. It is universally recognized as the premium roofing option, offering an unmatched level of prestige and long-term appreciation that composite materials cannot command.
