Roofing supports, also known as lathes, are thin strips of wood or metal that are used to provide a base for roofing materials such as shingles, tiles, and slates. They are typically nailed to the rafters of a roof and provide a stable surface for the roofing material to be attached to. Lathes are an essential part of any roofing job and can help ensure that the roof is properly installed and will last for many years.
