Different Slate Rooftops

• Standard slate roof
  A "Standard" slate roof is composed of slate approximately 3/16" thick. The pieces are of one uniform standard length and width and are cut with a square tail (or butt) which is then laid to uniform horizontal lines.
  
  Applying two or more sizes on the same area, which will not only vary the visible pattern but also create additional shadows and shading, may vary standard roofs.
• Textural slate roof
  A "Textural" slate roof designates pieces of material having a rougher texture than the "Standard" and perhaps uneven tails. They may even display variations of thickness or size. Different shades may be used to enhance the color effect of the overall design.
• Graduated slate roof
  A "Graduated" slate roof is a combination of the "Textural" slate utilizing even more modifications in thickness, size and exposure. The thickest and longest pieces are generally placed at the eaves and gradually diminish in size and thickness going up to the ridge

Slate Color
The color of Slate is determined by the chemical and mineralogical composition of the stone being quarried. Since these factors differ in various localities, it is possible to obtain slate roofing material in a variety of colors and shades.
