Our Standard Charcoal Roofing Tin Shingles are made of such brands as “Mansel,” “Dean,” “Worcester,” “P. T. L.” &c., and guaranteed to be first-class, well-coated plates, perfect in finish. Next comes our Galvanized (re-dipped) shingle; this is our Standard Tin Shingle, taken after it is made and dipped into melted zinc, adding a second coat of fully twenty pounds on each square, giving with the tin, a more durable coating than that used on galvanized iron, making it absolutely rust-proof and saving painting. Next is what we call “Old Process” or “M. F.” This is what is known as “Old Style,” “Double-Dipped,” “Old Method,” and other names, but what is really a very superior article of roofing plate, having a much heavier coating than “Standard,” but, like it, has to be painted. There are many brands of practically one quality in the market, and, having no choice ourselves, we supply the brand preferred; but if the best is asked for, we send “Old Process,” believing it to be equal to any.

THINGS ARE ONLY GOOD OR BAD BY COMPARISON.
Walter’s Patent Metallic Shingles Compared with Slate.
Our shingles are not one-sixth the weight of slate, which greatly reduces the cost of the frame-work of roof. They readily conform to the shape of a roof, which slate will not do. Slate is not thoroughly fire-proof, as heat from an adjoining building on fire will cause the slate to crack, which would destroy the best roof in a few minutes, leaving the sheeting exposed. Especially is this the case if water is thrown on them while hot.
Our shingles are free from the many accidents to which slate roofs are liable, such as cracking from shrinkage of wood-work to which they are attached; breaking, caused by necessary repairs to the valleys or chimneys; and the effect of frost on defective slate. Such defects cannot always be avoided by ordinary observation. All builders of experience are aware of the expensive repairs necessary to keep a slate roof in good order, but perhaps the most inconsistent thing connected with the whole roofing business is the fact that nineteen-twentieths of all the houses covered with slate have gutters lined with the same material of which our shingles are made, while slate was used for covering because of its supposed durability.
Should anything fall on our shingles it would probably dent them without causing a break; but should it perforate them, the shingles can be replaced by another, or a leak can be soldered, and fire from an adjoining roof cannot more than injure the paint. They will cool off rapidly, retaining their shape.
