possible, on the farm house, however well they 

 may be adapted to buildmgs in the 

 city. Metal roofs are not objec- 

 tionable in themselves, but only 

 when they are laid flat on farm 

 houses. 



The pitch of roofs, like their 

 shape, is also variable. Nothing 

 below one -third pitch should be 

 used except for special conditions. 

 In Fig. 38, page 127, is an illus- ^ 

 tration of the common pitch of ^ 

 roofs in fashion fifty years ago. ^ 

 Some roofs were even flatter than I 

 the one shown. The fashion now o 

 is to construct house roofs with § 

 nearly or quite half pitch. While f 

 steep roofs are desirable if made ^ 

 of wood, there is some danger ^ 

 that the change from the nearly ^ 

 flat roof to the steep one will be 

 carried too far (see Fig. 13, page 

 95). Various pitches of roofs are 

 shown in Fig. 61. Steep roofs do 

 not require as strong rafters, 

 thrust less upon the plates, are 

 more durable, and are less likely 

 to leak than flat roofs. 



Since roofs are of various pitches.
