Using metal roof is the new trend of constructing buildings. It uses quality roofing that guarantees longer span of the property. When using a metal roof, experts recommend not to use nails. Instead, screws with rubber plugs will do better. The temperature affects the expansion and contraction of the metal. Thus, the nails may come out and holes on the roof become massive. With this, using the best caulk for a metal roof is a smart decision.
