Sashco Through The Roof Sealant, Brush Grade, 1 Gallon Container, Clear (Pack of 1)

This stuff is the bomb! It works every time! I did have some issues getting it here and when it did get here the can was pretty mangled and I had to have a neighbor cut the top of it off in order to get to the goop, but once I did and I got it on my leak immediately stopped and this stuff usually lasts a few years. I'm going to try to never be without it again! And just FYI the sellers are absolutely outstanding! They had me covered from beginning to end!

This was recommended to me by a contractor when I needed to waterproof a roof from which shingles had blown off. It lasts a long time and is clear so it is not obvious. It has got the roof through periods when it is too wet, cold or slippery to repair.

I used this to touch up wind-worn shingles. Seems to work well and is easy to apply; it is quite thick like runny honey.

1 gallon really goes a long way. Take your time, sit down on your roof and look closely for any cracks or splits and go to town. I'm waiting on the next big rain.

Expensive compared to fibered and rubberized roof cement but stopped some leaks that the cheaper stuff couldn’t.I have a tar-and-gravel flat carport roof that runs right into the sloped roof of the house and the area where they join has been leaking worse and worse over the past years. I’ve slapped gallons of the fibered and rubberized roof cement on those areas several times and they have proved to be better than nothing – but not much better. Especially considering how long it takes to trowel that stuff in place.This year I finally broke down and ordered a gallon can of the Through The Roof stuff to see whether it would prove the old maxim, “You get what you pay for.”The application was easier and a bit faster than the cheaper stuff and according to the label I didn’t have to worry about the weather. I applied it with a four inch foam brush pretty much over areas where the fibered stuff was applied. The smell was not nice, but being out in the open air made it manageable. Following advice from other reviewers I used the entire can.It was dry and sunny that day but it rained quite a bit the next. That would have been an issue with the cheap stuff but is supposed to not matter with Through The Roof. The application stopped about 90% of leaks that multiple applications of the cheaper stuff have not. How much are you saving if you buy a gallon of roof sealer for $20, take the time to put it on and it does next to nothing? Now, I’m still going to keep some the cheap stuff around because it does a good job on many other areas of obvious disrepair, but for some reason it just wouldn’t do the job at that carport roof junction.I wish I could just coat the entire roof with Through The Roof, but I’m not in a position right now to take out a second mortgage.
