Bostik Evo Stik Flashing- How to apply flashband to repair roof or leak

If you have a minor crack on your roof, you can fix it quickly to avoid further damages. Using Bosik Flashband (around £20 from Screwfix) you can immediately stop the problem getting worse and it will probably last a couple of years before you consider a more permanent repair.

Even if you don't have any cracks on your flat roof now, you can treat your it with flashband to prevent future problems.

This video shows how in an hour and £20 you can repair minor wear and tear on your roof.

Suggest dealing with the internal corner of the parapet first. Both scissor cuts are at the same place. Fix a separate piece of Flashband to the upstand first then lap the main run onto it.

I wanted to ask, after watching this very handy tip, do you not have to use the primer every time you fix this flashband, i have a small repair to do and the first video i watched he smothered the whole thing in primer first, i just want to get it right first time, many thanks for this film

My brother has a very badly designed shower room; leaking into kitchen. Silicone no good. water splashing all over pvc cill. On a budget we fixed it with flashband. melting it on with a heat gun and pressing with a damp cloth was an absolute requirement. Aint going anywhere for a long time.

Hello sir i was wondering. I use the flashband in my roof but there’s a process that i need to use silicone sealant and then i put the flashband but i notice on the box that there’s an instruction like this ‘Flashband is bituminous and must not come into contact with silicone sealant’. I was wondering what will happen?

This repair has definitely lifted off by now, no primer and no heat gun when applying the flashband.

You wont find a professional roofer using Flashband, Its for DIY people, Im a roofer, i use torch on felt for more permanent repairs.

This is a TEMPORARY product. Only use it as a stop-gap for a maximum of a few weeks, until a roofer is ready to properly fix/replace your roof using proper materials.
It’s not designed for longterm 1yr+ usage. There’s a reason roofers use solid materials that last 10+ years for a reason. I'm not a roofer, but have had roofs done.
