Don't know if this is the right sub-forum buy here goes.....typical Monday morning, head not in it and whilst outside on top of the garage I had a bit of a mishap! I was drilling a small hole about 10mm, from outside into the attic space. Anyway unbeknown to me at the time of drilling the drill bit took another path and has managed to go through the breast creating a small hole in the attic area! What's the best way to fix this, I'm assumin you get some kind of heat resistant filler? Feel free to move this as well if I'm in the wrong section!
