No worries, glad you found it helpful :) Unfortunately there's no easy fix for rain noise. Twinwall (multiwall) is slightly quieter than profiled (e.g. corrugated) but not much. Without having insulation under it (like a house roof), you'll get rain noise. Thanks, Kurt.
Hey mate good vid. I have another reason to add from experience 😅 I have come looking for answers. The wind comes directly into my installed sheets and, in the areas where one sheet overlaps with another sheet, causes them to clatter against each other. What do you recommend to stop this? My first thought was to put some silicone in the ends but am hopeful of a less permanent solution. Cheers.
Hi there, thanks for the additional cause! There can be a couple of reasons for this. Is that the direction the wind normally comes from? If so, you may need to overlap the sheets the other way (e.g. the sheet that's under, put that one over top), i.e. so the wind blows over top of the overlap (not under the overlap). It may also be that your purlins aren't close enough together (and therefore your screw lines), allowing the sheet to flex too much between screws. If that doesn't fix it, there was a product called lap tape that was sticky on both sides. And it would stick the overlaps of the sheets to each other. However this was more trouble than it's worth as eventually it would get sediment and dirt stuck to it as well. Some people have also put noise stop tape down the overlapping edge, to minimise the rattling. I hope that helps? Cheers, Kurt.
Very useful video! I also think wind is causing this at my place with recently installed PVC roof. Only happens when it is windy.... Sure wish I had seen this video before the roofing was installed. I don't want to redo it, but don't want to have to replace it if it starts cracking in the next few years.
