David in Pennsylvania asked:

Trying to understand what this material is ..... multiple fine cracks everywhere and previous owner said EDPM, but doesn't look like it. Perhaps it's a coating they put on top? Either way, there was some water water/leaking in my upstairs neighbors' closet.

This is what Greg and Olief from USA General Contractors Corp. had to say in response to your question:
 
Please let this nice gentleman know that we do indeed service the Philadelphia area and can take care of this for him if he’s interested. But if he wants to attempt the repairs himself, I had my training and safety supervisor, Olief Lecky, take a look and provide an option for him.  See below:
 
That is not EPDM membrane on the roof, from the picture zoomed in you can see the size of the material from the lap seams but more importantly see the slag that I circled in the photo. so not sure by the picture exactly where the leak is but a good repair option for you would be to buy SBS cap sheet, asphalt primer and cold application. apply the primer direct to the aluminum coating then install the cap sheet as an overlay with cold app as your adhesive. Cut out for your pipes and reflash them with roof cement (karnak) and fabric then flash the perimeter of your overlay with fabric and roof cement.
If David would like us to handle it for him please have him email us at service@usagcc.com and we will help him resolve his issues.
 
Thank you,
Gregory Serevetas
