Question Roof Leak....I think?

After a long dry spell, we had 3 days of driving rains (sonoma county, CA). I monitored the inside ceiling and vents, speakers and found no signs of incoming water during the deluge. Later in the kitchen area I noticed some dampness on the floor in the area where the stove and 'fridge share a wall. (stove is 4" back from the 'fridge so creates a 'corner' and that is where I could see with the use of a flashlight, slight sheen of water between the wood paneling under 'fridge and stove and linoleum). I opened the panels under both appliances and noticed a bit of dampness under the 'fridge. I searched both areas carefully and felt upwards to see if there was dripping water or dampness of the interior wood and found none. Carefully checked the water heater and pipes running from it...again nothing. I put paper towels to wick the water from the area between stove and 'fridge and replaced towels about 6 times. Today the towel left overnight was dry.
Sorry this is long-winded, but I want to state what was done to locate potential leak.
Next step is to go up top and use a sealant where I might see cracks and around A/C, vents, and just for preventative measures.
In the past I had two RV repairmen check the roof for said preventative measures. One spent about an hour "sealing" the roof here and there. The problem is, I stupidly did not ask what was used. Is there a brushable sealant that I can use on an EPDM roof? (I noticed a small pint (?)sized can when the one guy came down from the roof.)
Since it is up to me, I'm hoping there is such a product that is fairly easy to use.
Suggestions? tips? products used? Thanks!!!!

Never us silicone any where to seal out water. I does not seal anything. It won't even stick to itself..

The refrigerator generates condensation under certain conditions. Some manufacturers drain to the bottom of the rig thru a small plastic tube and some manufacturers use a reservoir accessed from the outside refer access panel. Even though this appears to be rain related I would check this for problem.

In the kitchen area especially if it is a rear kitchen and your run off or gutter is near a window? It will leak in 1 place although it always shows in another . What I mean is , in the past RV's I have noticed water and it always leaks in the rear corner or gets in behind a window seal then filters down the insulation to the floor seal. If any water is trapped in the wall it cannot get out . It will steam in there until it it finds or weakens something to come out. It may be a precaution to remove a wall outlet and feel behind it in the wall to see if the insulation is wet? And if you like, removing the power to the trailer is a good idea because if the outlet box is wet when you pull it it may not be exactly safe to handle it. This will answer your question to how much water is in the wall. And if it is easy enough remove a few of the outlets in that wall to be sure the water isnt traveling the floor seal to the fridge area.

You could have a sidewall leak.
Without pictures of the sides or close ups, no telling what it could be.

Usually, Dicor 501LSW is used on EPDM roofs. No need to coat it. It does need to be CLEAN and DRY.

Can't use on a EPDM rubber roof....will destroy it...so no silicone..but thanks for the tip in case I thought to use it somewhere else...

When you find the area that is leaking, Eternabond tape properly applied is a wonderful remedy.

It is possible as I was not checking for water until the rains came..I will check the drainage tube and pull the panel again to check. When one goes into panic mode..rational thought goes out the window, so suggestions such as your are helpful and could simplify what I was guessing was something major.

I had roof leak and everything looked perfect on top. This rig was 12 yrs old. A RV teck said pull the AC unit. Sure enough the AC seal was installed improperly during original construction.

Also check (if you have) tubing for icemaker. Check under the vent for the refrigerator for signs of holes or slits. Buy dicor self leveling if you have the correct roof for it. Cost about $10.00 a tube.
