A cheap type of roof can be used similar to what is described for the stave 

 silo. The conical roofs need not be expensive and are more attractive. A door for 

 filling large enough to admit the carrier or elevator from the silage-cutter should 

 be left in the roof. The steeper roofs permit the silo to be filled above the top of 

 the wall, so as to be nearly full after settling. A simple type roof is shown in 



Fig. 17. Reinforcement around a 

 non-continuous door. 



The plate is made two-ply of inch boards sawed to the circle of the silo. The 

 2x4 rafters are attached to the plate and to a round circular block at the top of 

 the roof. A 2 x 4 piece is mortised in about half-way between the plate and the 

 block. The sheeting is sawn into triangular pieces diagonally across to prevent 

 waste. Prepared roofing is superior to shingles for silo roofs.
