Insurance ? Because of Hurricane Ike?

My daughter rents a home. The neighbor next to her also rents his. A tree, from the neighbors property, fell over & hit my daughters residence during hurricane Ike. It continues to fall over more & more each day. My daughter is concerned that with the weight of this tree it could possibly cave in the section of the house it is on top of now. Because of this situation she cannot get back into her residence with her 2 small children. The neighbor contacted his landlady to tell her she needed to have this tree removed that fell from HER property, but she said it's not her problem it's our daughter's landlord's problem! Isn't this tree the responsibility of the property owner's? Wouldn't this landladies insurance cover for something like this? My daughter can't get back into her home & has to keep finding friends to stay with because of this! Also when a guy came by to give a price quote he said he wanted $3,000 to remove this pecan tree! Where can he be reported to for trying to price gouge? Thanks for you time & help.
