Metal Tile / September 12, 2018 / FifineAsselin
Setting out Setting out the roofing before installation is a major part of any new roof build. With metal tile roofing it is imperative to get the correct gauge right from the start. Unlike concrete tiles that have a certain amount of play in the gauge measurements metal tiles have to be spot on or they will not fit. For this reason it is common practice to use set out pins to ensure accurate fixing of the batons. A measuring stick is used to mark the gauge up the rafter before driving in the set out pins. The batons are then cut in place before being lifted clear to allow the building paper to be laid. It is possible to cut down the setting out time by half by building a separate smaller gauging rod.
Choosing the color and design of a metal tile requires an aesthetic taste and you need to consider several other aspects of your home décor like the color of the flooring and walls. Many people are also opting for metal tiles for their roofing. If you cannot afford slate clay tiles or expensive wood; metal tiles provide a reasonably priced option. Although it works out costlier than asphalt a metal tiled roof is more economical in the long run. An asphalt roof is expected to last a maximum of thirty years without any problems whereas metal roofing usually carries a warranty for at least fifty years. The metal roof is very durable and has a high resistance to extreme weather conditions.
The smaller rod is used to fix batons around hips and valleys and saves a lot of time messing around with a tape. Cutting and bending At roof terminations and intersections tiles are cut to fit allowing for a 50mm bend in the tile. It is this turn up/down that provides the waterproofing of the roof. It is important to bend a sufficient upturn or water may be blown under the ridge or hip. I have found by taping the jaws of the bender with several layers of duct tape it allows the tiles to be gripped firmer without damaging the paint of the tile. Aim to use half the tile per cut. This will leave you enough metal to get another cut for the opposing side. Valley cutting Marking and cutting the valley at ground level gives a much neater appearance. Instead of measuring each tile cut individually the tiles are laid along the ground as if they were on the roof.
