A construction method for preventing crack by using a crack preventing cap of a roof edge in a slab structure is provided to restrict water from being infiltrated into a roof and to prevent crack of a building due to freezing of water infiltrated into the crack of the building by covering the crack preventing cap and draining water out of the roof edge. A crack preventing structure of a roof edge includes a roof(1) of a slab structure, an upper cap(2) of a slab parapet, a water stop sill(3) of the slab structure, and water stop eaves(4). The upper cap is covered in the roof regardless of shape of the slab roof to drain water out of the roof edge. Crack of the roof is prevented by restricting water melt from snow from being infiltrated into the slab structure with the water stop eaves. The water stop eaves are installed in the roof to restrict water from falling down along the building. |
