running low on pay shunts

gotten very frustrating the last few days or so...have 'dave' the roofer here putting on the metal roofing materials and oh boy, I had a subroof cut at McLanahan lumber and what does good ol dave do but NOT tear off the torchdown roof, not remove the rolled roofing, not take out any of the corroded rafters and NAIL the metal roof right over eberyting...I guess I'm going to tear out my hair and start screaming, he's got it just about all nailed down..makes you think everyone is in cahoots to charge arms and legs for stuff that needs doing and that I COULD HAVE DONE THIS B ETTER BY MYSELF..
