It has been four months since my conservatory roof was treated with your system. During this Autumn period there has been the usual high volume of heavy rain, often driven by high winds. So I think this has been a fair test of the Silent Roof system.
My wife, having disabilities, spends a great deal of her time in the conservatory watching television and reading. Before the system was fitted the noise of the rain falling on the plastic roof was such that she was obliged to turn the TV volume up almost to full power. If this continued for too long she would have to retreat to another part of the house. Your system has reduced the noise to a level where she no longer has to adjust the volume of the TV set.
I would certainly recommend the noise reduction qualities of the system.
