Would installing a lead flashing above a flat roofed extension be an easy DIY-able job?
Looked pretty easy on YT, just looking for a second opinion. The pessimist in me is worried what might happen if the groove I cut the the brickwork to install it into is not straight enough. What else could go wrong?
Where I am, squirrels discovered that chewed up lead tastes sweet, and have taken to eating it. This slowly poisons the squirrels and spreads lead in your garden. I recommend finding a different material.
