Luxurious Shelter

Matterhorn Slate, often referred to as Presidio Slate in the West, provides the luxurious and natural ambiance of hand-hewn quarried slate roofing. Chiseling and cracks are used to mimic the organic look of natural slate, and both embossing and weathered paint selections round out the appearance. A four-point interlocking system, tough 28 gauge steel and baked on Hylar/Kynar paint finish ensure strength and longevity.

We provide Matterhorn Slate in 1/2 SQ boxes (50 square feet). Each box contains 8 shake panels. Each panel is 22.125″ high by 47.5″ wide and covers 20.5″ high x 45.875″ wide once installed.

Matterhorn Slate is most often chosen for residential applications but functions well on light commercial roofs also.
