Butyl Tape for Repair Roof Leaks and Cracks 50mm(W) x 5 Meter (L) Strong Heavy Duty Waterproof Aluminum Sealant Flash Tape for Sealing Roof, Gutter, Tanking, Leaking Pipes- Repair Tape Indoor/Outdoor

I used it for a temporary repair on our gutters, no leaks so far. There’s a lot left over on the tape (large). I felt expensive, but actually it’s saved me a fortune on other potential repairs - especially while waiting for a contractor over the festival period.

Bought this to fix persistent gutter leak easy to use and did the job

I use this tape to waterproof guttering leading to water butts at my allotment. It works very well. It has good adhesion and lasts very well and does not leak. It is easy to cut and apply as it is flexible and sticky. Good value for money.

done the job great TY

Fantastic for sealing up some leaks in our shed roof, also great for bondage if your into that sort of thing, not that i am, honestly.

I used this for a tiny leak from a boiler. The water still leaked through. It was not on a part that gets heated, so there should not be any issue in that regard. I used it to stop a small drop of water every 15 seconds from the side of a cold pipe. It did not work at all. Update: I got an email from the team trying to resolve the problem, and issued a full refund. So, although the product did not work for me, seller's communication and service was excellent.

I haven't tried to use it yet because of the damage at the edges. I'm not sure it will work.

It's excellent does what it's supposed to do very well
