Hello,
I have a flat roof on my garage which is felt over rotten chipboard. What is the best way to remove this? I presume I go on top of the roof (minding not to step on the rotten part!) and cut the felt with a knife and then tear it up? What about the chipboard, that is nailed into the joists, so would I try and prise the wood from above, or push it from below?
Thanks.
