A trip to the contractor's desk at your local home center should give you a start. Get them to create a bill of materials for your project. That's no guarantee that if you order the materials the design will work.

The "attached to the front of my house" part is a concern, specifically the pitch and drainage arrangements of the existing roof and transition to the new structure. Since they will be connected, you will need at least pictures and a to-scale drawing of what exists.

If what you want to "figure out" is the materials, get the initial BOM from the home center and let a framing contractor or professional engineer review them.

If what you want to "figure out" is the roof and its effects on the existing structure, get a professional to help you with the design, not a software program.

also, you won't be able to go below 4:12 pitch without laying a double layer of felt or taking further precautions. you mentioned low-slope which to me is less than 2:12 so you may need to go with a membrane system in that case. make sure you get pressure treated lumber.
