The product works great. I had two water leaks and I brushed the leak fix in the area on the shingles and we had a rain the next day and not a drop leaked in. Thanks

Worked great, had a leaky valve and it sealed it up!

Value for money

Really good and effective product, very please with the results.

I had a spot on an older roof that needed to be replaced but I was planning on replacing it in a few months when the weather was nicer and i had the time. This stuff did a great job helping reseal the area where water had come through during a heavy storm. It smells like rubber cement and seems to have a slightly runnier consistency. With these shingles being extremely old and dried out, it didn't spread extremely far but filled in every gap quite in the granules nicely. I was able to use a brush to push it around the whole area. It's similar to putting on a thick asphalt sealer on a blacktop driveway but it is clear and made for shingles. Since the shingles were old and a lot of the connective material has disappeared, you could definitely tell a difference as it made these flat instead of the dried out granular top. The whole section where I put it looks much shinier than the old section. It probably brings it back to looking like a new shingled area. It did the job to seal it quite well; it's just definitely noticeable where you put it on an old roof.
