This standard roof pack has 4 of each straight and hip roof, enough for two separate buildings, or one large one. Both roofs are magnetic, and have biscuit and half pole accessory holes to help them attach. Straight roof additionally has half pole accessory holes on top for use with scaffolding or ridges. Pairs perfectly with Core Floors and Core Walls & Posts packs. This unpainted set is identical to Modular Roof Core - Standard Roof - Dark (Unpainted).

Note about Modular Roofs - the side holes on the modular roofs are all half-depth. Half-pegs should be used to attach roof pieces horizontally to each other, and for affixing the Soffit Pieces. Generally however it is easier to attach the modular roofs together using biscuits instead of half-pegs. 

Note about Straight Roofs - The two biscuit holes on the back of the Straight Roof are a fraction of a millimeter too narrow. As a result, it is difficult to insert a biscuit into them, particularly the bottom hole which is downright cantankerous.  Learn more about how to loosen biscuit fittings here.
