Hi Goody. If it's still raining, wait until it stops then get a step ladder and see if any water is pooling on a low spot on the roof. If there's a pool there, jack the side of the van the pool's on up until the pool flows away from that area. that's where your leak could be. I know you said you had the roof done, but if they didn't completely scape all the old sealant out, and force the new stuff in, it could still seep through there. You can also use the jockey wheel to raise the front to move the pool back so it flows off the back of the van. mark where the pool is closest to any seam and that's where you scrape out the sealant, then reseal it. That's how I found the leak in my vans roof. wiley.
