Yes I have a 2001 mobile home 16 x 70 with a 3x12 pitch shingles roof and I built a 12x24 back porch with step down on the back. I am turning the back porch into two room and need to add a roof. I plan on going from mid roof on house to end of new rooms. Will I need to stip back old shingles and add roofing felt under existing felt or what would be the best way to roof? And something else I would like to ask if ya, think that adding the new roof to the middle of my existing roof would be ok. You know would the trailer house hold up over the years or would it be best to add the new roof over the edge of the walls of the house. Thank You

Water is running down the middle of my patio roof, but it is not going into the gutter. The facia board that the gutter is attached to is covered with white aluminum. Water is seeping under the aluminum and dripping directly onto the ground. The leak is about the width of two shingles I tried using a garden hose to find the location of the leak. I started spraying water at the bottom of the roof, nearest the gutter. When I was halfway up the roof the leak started. Short of ripping off all the shingles and putting on a new roof, is there anything I can do? The shingles look good. They are all intact and there is no distortion or cupping.
