 often as the latter. 



The roof covering would better be of slate or 

 tiles, for the time has passed for building tem- 

 ^ porary, make- shift houses, though 



they might have served their pur- 

 well in a new and rapidly 

 developing country. With 

 rare exceptions, the houses 

 to be built in the future 

 should be per- 

 manently loca- 

 ted, well built, 

 and of durable 

 material. The 

 slates which 

 compose a roof 

 should be not 

 more than 8 

 inches wide and

 put on roofs of 

 less than one -third pitch, since they are only 

 double -lapped and do not lie as closely, one 

 upon the other, as do shingles, which are laid 

 triple -lapped. Slate and tile roofs are compara- 

 tively heavy, and hence require stronger roof 

 structures than shingles. 



The roof boarding for slate roofs should be
