Change Old Asbestos Roof for School

There is a small School house in Rural Puerto Vallarta Mexico, and it is a one room school house that teaches kids from first grade to sixth Grade.   In Any year you can find  15 up to 25 children who attend the small schoolhouse. The school has been made from the hands of the community over 20 years ago.  The roof, is an old asbestos roof that was put on when the school was orginally made, long time ago.  The children and teacher who go to this school really need a different roof, they do not have the means to change it themselves or their families or the community they live in. Please help this school.
