We install and repair slate and asbestos roofs. Contact our
professionals for more information.
Slate is a fine-grained, homogeneous, sedimentary rock composed
of clay or volcanic ash which has been metamorphosed in layers.
Slate can be made into roofing slates, because it has two lines of
breakability: cleavage and grain. This makes it possible to split slate
into thin sheets. Fine slate can also be used to hone knives.
Slate is mainly composed of quartz and muscovite (a mica), often
along with biotite, chlorite, and hematite, or, less frequently, apatite,
graphite, kaolin, magnetite, tourmaline, or zircon.
