The life of a British Columbia Red Cedar Shingle Roof can almost be gauged by the life of the nail with which the shingle is nailed in place. Judging from available data, the average life of the ordinary steel wire nail, which has been in such common use, is only from seven to twelve years. Some wire nails will last longer, depending upon the condition of exposure, climate and similar features, but considering our climate as a whole, at the end of from seven to twelve years a large percentage of wire nails will have rusted either completely through or so extensively that the first strong wind will complete the work. The shingles that have been held in position by such nails are then free to work down, permitting rains or melting snows to leak through and damage the interior of the structure. Examination will disclose that the fibre of the shingle itself is still in perfect condition, and a leaky roof, in the majority of occasions is due entirely to the use of faulty nails, but the average home owner, placed at such inconvenience, will not stop to reason this out and the poor wooden shingle comes in for more unjust abuse. There are several kinds of nails which experience has proven will give lasting satisfaction, and the wise dealer will advise his customers of these satisfactory nails. A pure zinc shingle nail meets all the demands of durability required. Its principal drawback is its high cost and a slight tendency to bend under careless driving. Galvanized wire nails theoretically are rust proof, and if the galvanized coating is properly applied, and of sufficient thickness, such a nail will last as long as the shingle it holds in place. The life of this shingle roof, properly applied with these nails then is from 40 to 50 years. Pure iron nails, or the old cut or wrought
