Everything You Need To Know About Slate Roofing

It is among the oldest roofing materials in existence, dating back (literally) millions of years. It is waterproof, slow to wear, and can look beautiful for generations. Slate is quarried as a metamorphic rock from shale-rich areas of the country. Slate roofing is a reliable, durable choice.

What is Slate?

Slate is rock. It is shale which has been transformed through time and pressure. It cleaves (splits) easily, can be shaped and drilled, and (because it is rock) is waterproof. When properly installed, a slate roof will shed water for nearly a century without any hint of water infiltration. In northern regions, it holds up beautifully to ice and snow, though in Florida that is seldom a concern.

Slate is wind-resistant, too, due to its heft. Crosswinds and wind sheer do not cause uplift on slate roofs.

Benefits of Slate

Homeowners today choose slate for its outstanding durability and unique look. Many other roofing materials attempt to match slate’s earthy, lustrous appearance. Slate needs little or no maintenance to keep it looking beautiful year-round. The little flecks of mica, quartz, and feldspar add sparkle to your roof.  

A slate roof is eye-catching, historically appropriate, wears better than just about any other roofing material, and is completely fireproof.

A slate roof will outlast most homeowners. This makes it far more environmentally friendly than shingle roofing, which (though it can be recycled) accounts for around five percent of landfill annually. When removed, slate — rock — is 100 percent natural.

Cons of Slate Roofing

No roofing material is perfect. Slate is heavy. It is rarely used today except in historical restoration, so many roofing contractors have no experience in properly installing a slate roof.

Slate roofing is as brittle as ceramic or concrete tile roofing. It can withstand a lot of abuse, but direct pressure can cause slate tiles to crack.

Slate roofing is more expensive to install than fiberglass-asphalt shingles, though slate outlasts shingles by more than 50 years.
