Thanks for sharing this. I just pulled the lens out, practically full of water. The first assumption is that it is a leak, but there was no water to be found except in the lens plate. The inside of the Skylight Dome was saturated with condensation.
It wasn't installed correctly in the first place. That lip should not be exposed on top of the roof. They should have slid it under the shingles so water could not get in. Additionally, there needed to be sealant under the base to protect it from water getting in.
I had a neighbor's mother say that she and her husband contacted Legionnaires Disease from their new skylights. I laughed so had afterwards, now i wonder, and almost say yes it could have been. That thing is a breeding ground for bacteria.
Change tubular skylight to instead a formed solid plastic or resin half sphere. It can now also heat the home by focusing sunlight onto a large interior bolder that would stay warm all night
This guy needs to learn more about these products. He says he's a roofer but doesn't seem to know much about these products. This is a cheap light tube and you get what you pay for, so spend the extra money any buy right the first time. If there is condensation in the light tube there is probably condensation in the attic as well because of poor ventilation. Warm air from the attic space is heating the tube, cold air from outside is cooling the air in the acrylic dome. Getting proper ventilation in the attic should help alleviate the condensation.
Thank you for your interest in my video and your expertise and passion for tubular skylights (Sun Tunnels). As you can gather from the video, this was an effort to simply inform customers of potential problems and is not intended in any way to be a platform to solve all questions and issues related to these lights. I am a roofer of 22 years and have inspected probably hundreds of these lights. While I agree that ventilation can be a contributing factor of condensation, I can also confirm that outside temperature against plastic has an affect and will likely increase moisture build-up. I mentioned in the video that this light was quite possibly purchased from a "box-store" indicating that it is not likely an expensive or high quality product. I hope this help. Thanks again.
I installed a Velux sun tunnel a few months ago in my bathroom. I operate an air exchanger continuously in the winter to keep humidity down but still find condensation to be somewhat of an issue. I have read some people spray foam insulation on the attic side of the tube but the problem is if any moisture gets into the tube it will eventually encounter a cold surface and condense. The product includes the energy kit (which gives you 2 additional lenses) but there is no double glazing like a window would have. I believe the issue is that the rubber seal/gasket that is at the ceiling ring is just not adequate to keep all moisture out. I have thought of beefing that up but suspect it would be almost impossible to make it moisture proof. On a positive note the ceiling cover is very easy to remove and I can wipe the lens off as needed. Keeping the air exchanger running certainly helps.
@@qualityroofing3944 So, would you agree; buying a Velux Sun Tunnel or Solatube would minimize the chances of this happening? And… is that installed correctly? I’m no waterproofing expert, but it seems to me the bottom of the dome should be flat so water runs evenly over the outside edges of the dome. The way it is oriented now, water would be running along the edges of the rubber gasket. In addition, if the dome was flat, there is more opportunity to collect and reflect light from all angles as the sun changes position throughout the year. Besides, it just looks weird! 🥴

Same condensation problem in Australia, ruins my plaster ceiling.
almost bought one. too good to be true.

I think a simple solar powered fan pointed up that tunnel would quite easily keep it nice and dry.
