WHAT OUR GOODS ARE.

In offering our goods to the public, we desire to say, briefly, that the Walter’s Patent Metallic Shingles and Siding Plates have now been before this country for nearly eight years, upwards of twelve thousand buildings have been covered with them in the United States and Canada, and we feel warranted in referring to the owners of every building so covered.

Our shingles have a concealed nailing flange the entire length of the shingle on one side, and a perfect lock with a concealed gutter at the side of the nailing flange that provides for expansion and contraction, with sufficient ventilation to prevent sweating on the under-side, (causing rust,) so common in the cross seams of flat lock and standing seam, now in use.

Our Galvanized (Re-dipped) Shingle is our Standard Tin Shingle galvanized; and, as every square has twenty pounds of zinc coating, in addition to the first coat of tin, it will be seen why it is superior to any galvanized iron made.

Our “Old Process” prices are designed to cover such grades of double-coated plates as “Old Style,” “M.F.,” “Phelp’s Triple Plate,” “Gilbertson’s Old Method,” and “Tregoning Old Process,” all superior to the Standard Grades, and higher in price. We quote all but Galvanized, painted both sides. If any size or kind is ordered unpainted, the price will be 25 cents per square less.

Our Steel Plate Shingles are made from sheets of Bessemer steel rolled as smooth as tin plate, they are painted the same as the Standard Shingles, and when laid on a roof cannot be distinguished from them. They should be painted every five years with pure linseed oil and oxide of iron (brown mineral). They will not bear neglect; in this respect they differ from shingles made from tin plate. The price is somewhat less, but the greater durability of the Tin Shingles is worth more than the difference in price.

We make our shingles in four sizes: The smallest, 7 × 10, (showing an exposed surface, after laid, of 5½ × 9 inches,) is designed for Mansards, Spires, Siding, and other upright work. The 10 × 14, (exposed surface, 8¼ × 11½ inches,) is the popular size; and while it works to the best advantage on complicated roofs, it is equally good for plain ones. The 14 × 20, (exposed surface, 12 × 17½ inches,) is used largely on the plainer roofs, where a saving in price and labor of putting on is an item. The 20 × 28, (exposed surface, 17½ × 25½ inches,) is made from heavier metal, and is designed for warehouses, and other large surfaces; and any of the larger shingles can be used for siding equally as well.

We are prepared to make any of the above sizes from any special brand of tin plate in the market, but for our Standard goods, which we carry in stock, we use a first-class grade of roofing tin plate, warranted perfect.
