Slate

The beautiful blue, grey, purple, green, red... colors of slate are often seen on homes, schools, and churches and many other types of buildings along the Main Line, in Chestnut Hill and University City, and around the area. Slate was very popular among the Victorians and was very well suited to the various and intricate roofs of that period. Slate was popular not only because it was fireproof and extremely durable but also because it's gorgeous. The colors and textures of a slate roof make the roof an important part of the building's design and character.

Slate's color comes from the types of minerals in it and is usually associated with a geographic location. Most of the slate in the US is mined in the East from New England through Virginia. Pennsylvania - where slate was first discovered in the US in 1734 - is known for Pennsylvania Black and Chapman. Chapman slate from the Lehigh Valley is known for its beautiful diagonal striations. Black slates are mined in Virginia, and the more colorful slates are found in Vermont. Slate has a lifetime of 100 to 200 years or more.

Ideal for Pitched Roofs

Slate works best on roofs that have a pretty good pitch , 8/12 or higher is best. It is ideal for turrets of Victorian Queen Anne's, the steep roofs of churches and can also be used on vertical walls. It is not suitable for low-sloped roofs.
