Keystone Library Commertial Roof

For this part of the project we had to resurch Green roofs, and then put on a the best layers for the green roof.  I also put on a curved roof for the top layer.  We also had to resurch low slope walkable roofs.  I learned that EPDM roofs can support the weight of people walking on then.  Also that concrete roofs can handle people walking on them http://www.wbdg.org/design/env_roofing.php   So from this project I learned how to created a curved and green roof and what materials are needed for their layers.  It was quite difficult to find information on low slope roofs but it helped in my decision of materials.
