GALVANIZED IRON. 



As a roof covering for barns, sheds, and miscell- 

 aneous outbuildings practical of purchase and delivery, no 

 better material than galvanized corrugated iron can be found. 

 Iron of good quality, of heavy gauge and properly galvanized 

 will last as long as an ordinary frame building. Shingles 

 ordinarily must be replaced at 10 to 15 year intervals. 



As a comparison of initial cost per 100 square 

 feet between iron roofing and shingles, counting shingles at 

 $4.00 per thousand, labor at $3.00 per day, iron at $8.00 

 per 100 square feet, plus an average freight rate of 2$ per 

 pound, shingles will cost $10.25 and iron will cost $10.50. 



Galvanized corrugated iron sheets are approximate- 

 ly 26 inches after corrugating and will lay 24 inches with 

 a lap of one corrugation, see Cut No. B.M.-2. End lap 

 should be 4 inches on 1/3 pitch roof and less, and 3 inches 

 on roofs of more than 1/3 pitch. Laps must be taken into 

 account in estimating quantities of iron required. 



To fasten galvanized iron roofing, use 2 inch No., S 

 galvanized roofing nails with No. 8 lea_d washers. Lead 

 washers not only make waterproof joints, but also prevent 

 rust of the edges of the nail hole. 



26-Gauge plain ridge cap 7^-"x7^" should be used 

 for comb finish. It is sold in 6, 7, 8, 9 and 10 foot 

 lengths; weight approximately .35 pounds per foot.
