A Gerard Roof is excellent compared to other steel products. The low noise impact is the result of textured, stone granules and smaller steel sheets pressed into tiles, which minimizes the sound transmission through to the house.
Longrun steel roofs allow sound to travel in waves along the full length of the sheets meaning that noise transmission into the home can be quite high. Gerard Roofs pressed steel tiles are short lengths of metal fitted together so sound is unable to travel and any rain impact noise dulls quickly.
