 Dear Dr. Kennedy J - 



Some time ago, our representative left one of our "Asphalt Circulars" 

 at your residence. We took this liberty with no intention of encroaching 

 upon your time, but assuming that a Process capable of not only the elimi- 

 nation of the necessity of reshingling a roof every few years, but also the 

 transformation of a shingled-roof into a fac-simile of slate, free from all 

 the objectionable qualities attending the latter, might possibly interest you. 



The treatment of a shingled-roof with our Process renders it as Dur- 

 able, Fire and Water-Proof as slate; during hot weather, its imperviousness 

 to heat lowers the temperature in the attic to a marked degree; its weight 

 being slight, there is no possibility of the rafters sagging, which often 

 occurs in a slated roof; its lubricity is such that snow slides off readily, 

 and the liability of the overflowing of gutters is reduced to a minimum; the 

 cementing of the overlapping course of shingle-butts to the one beneath it, 

 prevents the water from backing up and freezing under the shingles during 

 the winter months, which is the cause of much of the leakage in both shingled 

 and slated roofs. 



That the quality of present-day shingles is so poor (the cause of 

 which is the use of young-growth timber made necessary by the scarcity of 

 the better grades, on account of the rapid diminution of our forest resources) 

 they will not give long service without protection; that they will warp and 

 split after a few years' exposure to the weather, more especially on the 

 south side; that the extraction of the sap by the sun leaves the shingles 

 soft and porous, permitting the penetrating of moisture to such an extent 

 that it causes the nail heads to rust, and the result is, the shingles soon 

 loosen and blow off, — this can be proved beyond the power of contradiction 

 upon the examination of most any roof, a few years after being shingled.
