I can't help you directly. Our top downs are based upon historically accurate roofs and bear no resemnlance to the roofs in the graphic you posted. However, there might be a good answer, depending upon your mapping tools. Your bio doesn't tell us what software you use. If you use CC2, CC2 Pro or CC3, the ProFantasy website has a free download of similar vector symbols created 10 years ago or so by a CC2 user. However, these symbols work only in CC2, CC2 Pro and CC3.
