Slate

Actual slate is shingle-like slivers of rock - is another roofing material that shows up on more upscale homes. Although slate is an expensive choice, it offers a very natural look and can be laid out in a variety of patterns.  The benefits of slate are identical to those of tile: a very long lifespan, good fire protection, low maintenance, and an invulnerably to rot and insects.  It comes in a good selection of sizes and colors, although colors are limited to those found in nature.  Like tile, slate can be very heavy, sometimes requiring expensive extra support.  It, to, is breakable enough that walking on it is difficult for a non-professional, complicating such tasks as rooftop maintenance, gutter cleaning and painting.

Considerations

Slate is a dense, tough, durable, natural rock or stone material that is practically nonabsorbent.  Standard slate roofs are composed of standard (approximately 3/16 to 1/4 inch thick) commercial slate, having a uniform length and width, and having square tails or butts.  Standard commercial slate may be used to form a variety of designs on the roof and are suitable for many buildings where a long service-life steep-slope roof covering is desirable.  Variety in the pattern can be attained by using slate trimmed to a diamond, hexagonal or other pattern or by using random widths.  Graduated slate roofs feature variations in thickness, size and exposure of each course to make the eave to ridge distance look longer, and give the roof a more massive appearance.
