the dealer said i needed a new roof. there is a soft area between the a/c and by the antenna. this trailer is only 6 years old and mostly sits in my driveway, very few miles. this is my 3rd trailer ...
I would cut the back to the rafters on either side of the rot. Replace the wood. Buy a piece of roof material and glue it to the wood. Take some Eterna Bond tape and tape the new seams. Just for extra insurance coat the whole roof with Henry 887.
