Had to work with a different type of metal last weekend thanks to some strong gusts of wind (I am not a fan of wind - it has done more damage around here than anything else). No hammering required though - just replacing some stripped screws & thankfully I can recruit my boyfriend to climb on top of the barn to replace said screws ;). If you've never heard a metal roof come loose & repeatedly bang against the frame it is LOUD! So we had to fix it ASAP before my horses had an emotional melt down which would have then required me to spend days convincing them that the barn was safe for them to go into. Thankfully all is quiet around here again for the time being except of course for my 2 loud geese, rooster & 2 guineas ;).
