High quality roof closures: From verge to shed
A covered roof surface can only be as functional and reliable as the overall roof system. Consequently, the roof closure also plays an important role in the durability and weather resistance of a roof. Special attention should be paid to roof closures. The lateral roof closure is called the verge – it forms the transition to the façade at the vertical gable. The verge connects the eaves to the ridge and is frequently referred to as the front of the house. When looking at a house, the focus is on the verge. It therefore frequently has a very sophisticated design or is highly decorated. It is also important that this part of the roof is protected from driving rain and moisture penetration.
The double roll tile is an alternative closure to the verge without leg. Use of clay and concrete double roll tiles avoids visible grooves at the open side of the field tile, producing a consistent roof surface appearance at the left and right side. The double roll tile can also be used on the left side of roof windows, and normal field tiles are used on the right. The half-width tile compensates for the coverage width that cannot be achieved by a normal clay roof tile or concrete roof tile. With clay roof tiles that are laid in bond, every second row must begin and end with a half-width tile. The half-width tile gauge and interlock are identical to the field tile and concrete roof tile.
The shed roof, which was originally used above all for simple structures and ancillary buildings, is enjoying renewed popularity and contemporary architecture; shed roof combinations in particular can form attractive roofscapes. The surface of the shed roof usually faces the weather to shield from wind, rain and snow. Special clay shed roof tiles and concrete shed roof tiles are used at the shed closure.
