We have a flat roof over an enclosed sunroom that was resurfaced four years ago. The contractor did not introduce any angle to the roof, so water sits there after a rain. The roof also leaks around the perimeter, to the point that the paint is peeling inside the sunroom.
My question: Should the roof have been angled to begin with? Should we try to re-roof and introduce an angle ourselves? We just want the roof to shed water, instead of acting as a pool.
