The tiles must be tight and correctly aligned. The bottom and top course is then marked using a bevel. Two people may now chalk a line along the length of the valley. This gives a much straighter line than individual measurements. Laying the tiles Contrary to other roofing practices pressed steel tiles are best laid from the ridge down. Lay the under lap into the prevailing wind. This will ensure the maximum wind resistance and stop the roof lifting. The first full top course is laid out and fixed at the head of the tile allowing the subsequent row to be slid underneath the bottom. It is important to even out the tiles to make the best use of the cut ends.
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.
For roofing it is entirely another story as you will need professionals who are specialized in this type of work. The instructions from the manufacturer have to be followed to the last detail if you want to reap the benefits of the warranty which is being offered. There will be special instructions for preparing the surface under-laying and so on. Metal roofing tiles offer an attractive solution to modern roof coverings. Pressed metal tiles come in a number of different styles mimicking more traditional clay or slate roofing. Metal roofing tiles have come a long way since their introduction 50 years ago. The first tiles introduced had a bitumen coating which tended to melt in hot climates.
