Gingerich Builders

.Although Gingerich told us he was going to put at least a 2"x8" beam down the center of the mobile home roof to give the metal roof a slight pitch, he did not.  He put the entire weight of the metal roof panels and lumber used on roof which was not much, directly onto our old roof and as a result, our ceiling inside is caving in.  We currently have our ceiling propped up with posts, my husband had to remove the kitchen cabinet door because the ceiling had caved in so much I could not even open the cabinet doors.  We were in shock.  What on earth was happening.  As I type this, I feel the horrible stress one feels when you know your roof can come down at any time.  So far each day brings the ceiling down about 1/2" or so. 
I dreamed of enjoying my new porch and looked forward to sitting at my outdoor table enjoying the rain.  But due to their shabby job, I have to prop plywood about a foot from the porch edge or the rain water will splash all over everything.  And the hole in the new panel is patched with a screw. 
After calling Gingerich Builders over 5 times to get them to come back and do something about this horrible job (we are retired and had saved dearly to get a good solid roof over our heads).  He came out today and basically told us "Hey, what can I do? I'd have to do the whole job over again and that ain't going to happen.  I put a screw and caulk in the hole we accidentally made in the porch roof."  I think he thinks we're too old to do anything about this mess but we aren't.
