Ed, at the risk of beating a dead horse, and I am not trying to be a pain, but the fact that you say it has a glass top that slides down revealing a roll up screen tells me it is not just a screen door. Any outer door that has glass in it is a storm/screen door. There is a difference. I do not believe, (but I could be wrong), that the builder never installed these. Since the home is now older, it is a moot point.
There should be some markings on it saying if is a Larson door or an Andersen door. Contacting that company or any good screen person should get you the info you need. There should be a way to replace the screen part of the door.
Just a coincidence, but my front porch is screen enclosed with a screen door. The screen was getting old, (about 14 years), and I just replaced the screen yesterday. Took me about 30 minutes.
I looked on YouTube and they do show step by step instructions on replacing these type screens. Looks pretty easy. Hope this helps!
Frank
