Characteristics of Slate
The principal
difference between slate and other stones is the natural cleavage
construction of the slate. This permits it to be split in one direction
into sheets of various thicknesses. It is cut and trimmed mostly by hand
labor into the required sizes and thicknesses. A slate roof is really a
custom-made job and its use gives a character to a building unlike that of
any other roofing. Slate quarried for roofing is of dense, sound rock and
is exceedingly tough and durable. Some slate roofs in Vermont have been on
for over a hundred years. Roofing slate is split to various thicknesses
from commercial 3/16� thick up to 1� in thickness for heavy graduated
thicknesses of slate roofs.
Colors of Vermont Slate
The following colors are listed according to relative cost starting with
the lowest cost.
Semi-weathering,
Green and Gray � Loosely called Sea Green, it is the basic product of
Rising & Nelson and most widely known and used. Green or grayish green
when first quarried, upon exposure to elements a percentage change to soft
tones of buff and brown, the remainder retaining initial color. This
gradual change serves to beautify the roof and in no way affects the
durability of the slate. Interspersed in a mixed color roof, this slate
will eliminate sharp contrasts and improve the blend immeasurably.
Vermont Gray
Black � Gray Black in color with shades varying slightly. Available in
smooth or rough texture; can experience slight degree of weathering.
