How much weight does wet snow on roof add?

Ok, so I picked up a load in PA this morning, supposed to be 42000 lb, but my total weight at cat scale is coming up as 81500. There is a few inches of wet snow on the roof of the trailer - is that enough to account for discrepancy?


I am thinking of just waiting for it to melt off instead of going back to customer for overweight reload.

Did some rough math - according to the internet, wet snow is 20lb per cubic foot. 53 feet × 8.5 feet × .3 feet of snow height × 20lb = 2,700lb. Dang, snow is heavy. If true, that would be enough to account for extra weight.

Thoughts? I don't want to go back to the customer and look like an idiot complaining about too much weight, but I also don't want to find myself 300 miles away from customer and still over 80000lb after it melts...

 

Usually with that 42000 pound load I would be at about 77000 lb

 

I know what you mean about that. Luckily, my snow is sort of wet and compact, it's neither blowing off nor coming apart in ice sheets. Just hanging out up there and safely melting.

 

When I get to Ohio later today and the snow melts, I'm going to go get another scale ticket and post it here for science
