Calking around air conditioner shroud on roof
I have a small 16ft trailer, with a small side mounted air. On the roof is your typical air mounted plastic cover. I see four small round areas that have lap sealant on top of the screws (I think) ...

Hi,
There should not be caulking on the screws on top of the A/C shroud. This is so that you can remove it easy. And any water leaking past those screws will land in the A/C unit basepan, and drain harmlessly to the roof through it's drip pan drain. Water gets into the A/C all the time, this is normal.
If you are getting water inside, and to prevent rain from getting inside, it is best to tighten the A/C gasket and hold down bolts about every 3 years. Take off the inside shroud. Clean the filter at this time too, as it probably will need it. Look for 4 bolts, in the corners of the part you are looking at, for 1/2" or 9/16" bolt heads. Tighten them 'slightly' not crank them down, or even get them much past finger tight. Perhaps finger tight +1 turn? As you tighten the bolts, it compresses the gasket, and then you go back and compress it a bit more in 3 years, and more in 6 years. Once it is fully compressed, and then starts leaking, it is time to remove the A/C from the roof, replace the gasket, and start all over. . ..
Good luck!
