To prevent thermal expansion and contraction of the metal roof, sliding fasteners are used. This type of fastener allows the metal to move freely when the metal roof expands or contracts. When installing the roof, it is necessary to leave gaps between the edges of the roof and the panels to prevent deformation of the roof. The use of compensators and the correct placement of the folds will absorb thermal fluctuations. Considering all these nuances and factors, you will prevent thermal expansion or contraction of the metal roof, ensuring integrity and functionality for a long time.
