ROOF. 



Materials for roofs of different pitches are pro- 

 vided. At elevations within the respective ranges use the 

 roofs of stated pitches. Exception to the above should oc- 

 cur only where snowfall is not a source of hazard as on some 

 of the southern Forests and on the Modoc. 



Where roof trusses are used fasten the members se- 

 curely with lOd. nails in members 1 inch thick and with 20d. 

 nails in members 2 inches thick. 



Rafters and other members of the roof frame should 

 be of selected straight grain lumber; first choice Douglas 

 fir, second choice white fir, third choice yellow pine, free 

 from knots and other imperfections. Too much attention 

 cannot be given to the selection of the best sticks of the 

 lumber order for rafters. 



The roof is to be sheeted with 1" x 4" sheeting 

 laid 8 inches to weather, projecting the sheeting over gable 

 ends to outside of barge boardSt 



Place barge boards as shown in the plans. 



Care should be taken to cut the rafters true in 

 order that they rest firmly on the plate, meet squarely at 

 the apex of the roof. 



Rafter ends over eave projections shall be sheeted 

 solid with 1" x 12" lumber. Rafter ends- shall be trimmed 

 as shown in diagram. 



Gable end projection should be finished by planting 

 soffit boards on under side of the projected 1" x 4" sheeting. 



Rafter ends should be finished in the manner illus- 

 trated by the diagram "Section". 



Use for roof covering either - 

 (1) Star A Star red cedar or redwood shingles 

 () Shakes of white fir or sugar pine. 

 (3) Galvanized iron (see B.M. Page 8 ).
