Review: Great value flashing tape that sticks well - A bit tricky peeling the backing off but this stuff is great. Used it to repair my flat roof where it had a crack & to seal around a stack pipe that went through the roof & had been bodged with silicone they shrank leaving a gap. Sticks really well, no rain to test it yet but looks like it will do the job.
Review: Very pleased, just right for the job in hand - This is really good stuff. I used it to cover a plastic roof on a pergola which had some holes in it. I believe that this will help protect the roof and add years to its lifespan. It is VERY sticky if used on a warm sunny day so you need to be prepared.

## Questions & Answers

**Q: I just bought some, gives very little information on how to make it stick!**
A: You want to place it in the sun for an hour if possible before use. If at room temperature it should stick to many surfaces. If not, heat briefly with a gas gun as you lay it on. Also you can use a wallpaper edging roller once it’s in place to help make it bond.

**Q: Will it work to stop lead flash slipping on a slate roof.**
A: Yes, you can use it to replace damaged lead flashing too, adheres to slate, stone, brick, wood etc,,.

**Q: Can this be painted over ?**
A: I’ve only used sealant paint on it no problem, it sticks to it and doesn’t peel off. 
I think gloss paint would be fine.

**Q: is it butyl**
A: Yes, needs to be heated slightly, a hairdryer works and is then very easily worked into place.

### ⭐⭐⭐⭐ So far so good - No leaks
*by R***H on 9 July 2026*

Used in my coping stones to repair the joints. I painted over these to definitely make sure no water could leak through. We had a leak last year and we could only put it down to the joints. So far so good. Good preparation is key - clean and use a roller to press the tape to confirm it has stuck
