Wall building system

A roof system comprising:

• removably attachable roof panels that are coupled together to create a roof, the removably attachable roof panels comprising:
• a first side with a first outer covering,
• a second side with a second outer covering, and
• a core interposed between the first and second outer coverings, first and second fingers at each end of the roof panels;
• wherein ends of the removably attachable roof panels each comprise a recessed portion with the first finger and the second finger on opposite sides of the recessed portion, the first and second fingers each comprise first depressions and second depressions;
• wherein when the second fingers on two of the removably attachable roof panels are mated, a protrusion is created;
• couplers that fasten each of the removably attachable roof panels to each other, the couplers comprising:
• a first member,
• a second member,
• a first recession interposed between the first member and the second member,
• a third member,
• a fourth member, and
• a second recession interposed between the third member and the fourth member.

• wherein hooked members are positioned at the base of the second fingers;
• couplers that fasten each of the removably attachable roof panels to each other, the couplers comprising:
• a first member,
• a second member,
• a first recession interposed between the first member and the second member,
• a third member,
• a fourth member, and
• a second recession interposed between the third member and the fourth member;
• caps that are placed at the junction of two removably attachable roof panels, the caps comprising:
• an upper portion with a ridge,
• a first leg and a second leg descending from opposite sides of the upper portion,
• a first digit on the first leg distally from the upper portion,
• a second digit on the second leg distally from the upper portion,
• wherein the first and second digit are positioned underneath the hooked members to secure the caps to the removably attachable roof panels,
• wherein the removably attachable roof panels and the one or more couplers receive and conceal electrical and plumbing components.
