You recommended Peel & Seal PowerBond 250 but the installers of the insulated aluminum roof panels has put additional flashing and caulking over the exterior seams. The problem continues.
How would Peel & Seal PowerBond 250 fix the problem? My roof has basically become unusable and the installers can't figure out how to fix it short of taking all the roof panels and window panes out to reinstall them.
Your suggestions would be appreciated.
