DESCRIPTION. Proslate is our regular Paroid roofing material with an
additional wearing surface (not a colored coating) of a mixture of
paint and sand, making a _slate-like_ surface, _slate_ in
color and effect. Proslate is an entirely new material—patented.
FOR PITCH ROOFS. Proslate is especially designed to take the place of
shingles and clapboards for residences. Attractiveness and economy
are both secured by using Proslate for pitch roofs. It is finished in
18-inch rolls, ready to lay, with ornamented edge.
Proslate is applied in the usual way—lapped, cemented and nailed—no
waste by excessive overlapping—cement and fixtures of same slate color
with complete directions for laying are packed in each roll. Any good
carpenter can apply it.
Proslate is finished in rolls containing 122 square feet, sufficient
to cover 100 square feet of surface and is sold on a basis of material
enough to cover 100 square feet.
FOR FLAT ROOFS AND SIDING. For flat roofs and as a siding, we furnish
Proslate in rolls 36 inches wide, plain straight edges. By the use of
broad cleats, a very neat effect can be made on the sides of houses.
Proslate for a siding is warmer than clapboards or shingles. It acts as
a blanket.
GENERAL USE. As a permanent all round roof, we believe that Proslate
represents the best material for the money yet made. It is good
enough for residences, factories and railroad buildings. Shingles are
unsatisfactory and cannot be used on flat roofs, porches, etc., and
slate is too expensive. Proslate fills every requirement of a good
roofing, well made with an extra weather surface, economical—permanent.
