I wish I would have known about this kind of tape a lot earlier in my life. Compared to other options, such as spray-on rubberized coating, this stuff is a breeze to use as there is no cleanup needed. It could have made some repair jobs (both temporary and long-term) so much easier for me. It makes a great alternative to flashing in some cases. I am using it on top of my steel garden shed. The roofs on those types of sheds are always poorly sealed. They actually included a roll of standard duct tape with mine for sealing the roof ridge. This duct tape disintegrated a long time ago due to the elements. I just removed the long metal cover piece and used the new tape to seal the entire length of the roof panels. After application, nothing is getting through, not air or sunlight. This is great and should keep the inside of the shed much dryer. I would suggest applying the tape on a warm day for the best adhesion. If its cold outside, warm the surface with a heat gun first. The adhesive is not a hot-melt glue, but Im sure it works better when warm. I just wish I knew about it earlier so I could have used it under my deck boards. I did coat everything with a waterproofer, but that stuff wears off after a few years.
