House trailer separating!? When the roofers removed the old roof on a house trailer, they...

When the roofers removed the old roof on a house trailer, they pointed out a 3 to 4 inch fracture between the trusses where the trailer halves be put together. When they removed the old roof a .040 aluminum coil stock come up with the roof that over lapped the two halves. When they replaced the roof they didn't put any metal fund , just over lapped the asphalt paper and put on ridge vent.
Now looking a few months later I notice my foundation cracking in the center and cracks within my interior getting larger. Can I sue the roofer's for this is happening since they didn't put the aluminum final in the center?

Answers:    Question is, be that an open ridge vent or is it the fill bolts not being properly tightened?? There are several be to roof a doublewide mobile home .I think the aluminum coil is a moot point contained by this.i suggest a home inspection service to find out if the foundation is sinking or unstable, and if the lag bolts that hold the 2 halves together are not properly tight. Also the roofer should enjoy noticed if the lags weren't surrounded by place and corrected this.
