Slate Roofing
Real slate is the longest-lasting residential roof on the market, 100+ years of beauty and performance. We install and repair slate across the Peninsula.
Quality Roofing Since 2002
What Slate Roofing Is
Real slate is quarried stone split into thin tiles. Synthetic slate uses recycled rubber/polymer to mimic the look at a fraction of the weight and cost.
Benefits
Unmatched lifespan, premium aesthetics, fully fire-resistant, and a major boost to home value. Synthetic slate offers most of the look at lighter weight.
When To Choose Slate
Best for high-end homes where lifetime value and premium curb appeal matter. Real slate requires reinforced framing, synthetic options work on more homes.

Frequently Asked Questions
How long does a slate roof last?
Natural slate is the longest-lasting roofing material available — high-quality slate roofs routinely last 100–150 years. Synthetic slate typically lasts 40–50 years. If you're planning to own your home long-term, a slate roof may be the last roof you ever install.
What's the difference between natural and synthetic slate?
Natural slate is quarried stone — extremely durable, heavy, and premium in appearance. Synthetic slate uses recycled rubber or polymer to mimic the look at significantly less weight and cost. Both are excellent options; the right choice depends on your framing, budget, and aesthetic goals.
Is slate roofing a good investment in the Bay Area?
Yes, particularly for higher-value homes. Slate adds curb appeal, increases resale value, and eliminates the need for roof replacement for decades. In Palo Alto, Menlo Park, and similar markets, premium roofing materials are expected on higher-end properties.
Can a slate roof be repaired rather than replaced?
Absolutely. One of slate's advantages is that individual tiles can be replaced without disturbing the whole roof. Slate repairs require experience — working on slate without breaking surrounding tiles takes skill. We've been doing it since 2002.
Why does slate roofing cost more than other materials?
Material cost, weight, and installation complexity all contribute. Slate requires specialized tools, careful handling, precise nailing, and attention to flashing details that other materials don't demand. Done right, it's worth every dollar. Done wrong, it leaks. Experience matters.
