Caulking around roof vents and ac unit
What is best way to do this? What type of sealant or caulk to use? How often should it be done. We have no leaks but just want to do preventive maintenance

Around vents and skylights. Eternabond or Dicor Lap Sealant (not the self leveling kind)
Around air conditioner DO NOT CAULK!!!
There is a foam rubber gasket between the upper unit and the roof. Tighten the 4 bolts that go through the roof to the specified torque and it should not leak.
IF it does, remove the 4 bolts. and disconnect the wires that go to the top from the bottom (usually Molex plugs that only plug in one way) remove the top unit and the gasket and drop on another gasket.. Then replace.
Also, while top side (Even if not removing the upper unit) "pop the top" (Remove the shroud) and the inner covers and clean clean clean, Epically the condenser and evaporator coils and any path where water should flow (the plastic tray below the condenser) This will give you better A/C operation Also clean the inside filters.
