ok so i have a small section of roof, that is NOT conected to the main roof of the house, the section is maybe 3 ft by 5 ft, it’s got a slight slope and is over a bay window. it is currently not shingled, there is a black hard material over the roof that is cracked in places and looks worn, and has some give like it’s lose if i push in places. it does NOT feel like there is any give in the boards underneath and there is no water damage inside other than a few drips that i just noticed yesterday. how do i fix this problem before serious damage occurs? also there is a small lip? at the edge, where water pools, is this normal how do i shingle if that is indeed the solution an area like that?
thanks so much
