Slate Roofs and Roofing

Slate roofing is a high-cost, high-reward material.  It is one of the most expensive roofing materials on the market but offers a large number of benefits.  Slate roofing is:

  • Very attractive, available in natural colors and styles. It has an upscale look.
  • Very durable, since it is stone.  It holds up well to wind, hail and sun.
  • Able to shed water and snow very well.
  • Nearly maintenance-free.
  • Resistant to fire, insects and rot.
  • Environmentally friendly.
  • Energy-efficient.  It absorbs less heat energy than asphalt shingles.

Description of Slate Roofing

Slate roofing is made from slate, like chips or thin slabs of rock.  It is produced from stone mined in areas such as Vermont, Pennsylvania, China, Spain and Canada. Genuine slate roofs have long been popular in Europe and have been employed in the U.S. for nearly 200 years.   Synthetic slate is also available, made from slate dust and glass fiber resin.  Cement/resin slate is a second type of synthetic slate being used in more installations. One advantage to synthetic slate is that the mixture can be tinted to produce more colors than found in natural slate.

Genuine slate roofing is very heavy and existing homes may have to be structurally reinforced to support them.  They require heavy-duty framing and decking in new construction to meet the strength requirements.

Slating a roof, as it is called, is an art form, best handled by professional slate roofers with good experience.  There are many specific rules that apply to slate roofing that don’t apply to other forms, so having experience is essential.  The slate is overlapped, with steeper roofs requiring less overlap, and staggered to prevent water from seeping down to the wood roof deck.

Cost of Slate Roofing

As noted, natural slate is one of the most expensive roofing materials on the market.  A roofer’s square will cost between $500 and $800, or $5 to $8 per square foot for just the material. Read more about costing out a slate roof at Slate Shingle Cost Guide.

Slate Roofing Longevity

After the luxurious beauty of slate roofing, its durability is its finest quality.  A slate roof should last at least 100 years.  There are many examples of slate roofs that are in very good condition despite being over 200 years old.

Where is Slate Roofing Used?

While slate roofing was first introduced in the U.S. in New England, it can now be found on homes and buildings throughout the country.  It is a popular choice where classic beauty and old-world charm are desired.  Its ability to shed water makes it a good choice in wet climates; its strength and durability lend itself to harsh weather.
