All the screws on the metal roof needed to be replaced. The company used galvanized screws which rusted, DUH! So they had to replace all the screws with stainless steel screws. But first the solar panels had to be removed so the roofers could remove old screws and put the new ones in.
Panels stacked up while the roofers putting in the new screws.
One roofer removes the old screws while the other guy puts the new screw in. Different head size between the old screws and the new screws.
Solar panel reinstall!
Back up and running!
