Help Me- My insulated aluminum Roof leaks

I am trying to repair my aluminum insulated sunroom roof. We have experienced several leaks in the interior of our room. The leaks are coming from the seams/edges of the panels. The roofer states that the leaks could be caused by our house roof which is absurd according to a structural engineer, because the sunroom roof is not attached to our house roof. It is attached to the soffit. The roofer did come out and tape the seams, but the leaks still continued-Also we are experiencing a sometimes loud and other times not so loud popping.
Should I pull up the tape on the seams on the exterior of the roof, clean out old caulk, wipe out any water that may still remain, and re-caulk them?
And how can I solve the popping of the roof that we are experiencing?
Thanks for your time and any suggestions that you may have.
My Roof

You really did not spend much time describing your roof, it's construction or how it's attached to the house. Can you include photos of the problem areas and how your sunroom attaches to the house? I'm not sure how your roof could be attached to the house's soffit. I can see it butting up against the wall or fascia but am having trouble visualizing hot it attaches to the soffit. Anyhow, it is possible for water to be somehow wicking around from the house roof, it all depends on how it's constructed but that is a common leak point. A seam or fastener is also a possible leak source.

Popping can be from the aluminum, insulation, connecting strips and everything else expanding and contracting at different rates as the temperature and sunshine changes. If the popping is coming from the ceiling panels it could indicate that the sheeting has delaminated from the foam or cardboard core though it's more likely to be movement at the seams.

It sounds like structural issues are causing your leak that nobody can explain without good pictures of the area in question. Roof to wall intersections have to be flashed correctly, otherwise water intrusion will happen.

You can clean and re-caulk if you like but you should know no caulking of any kind was ever designed to be the first line of defense against significant water intrusion, only to seal certain areas against wind-driven rain that may move sideways and try to slip under a shingle or a flahing. If you re-caulk it may stop the leak for awhile but this will now become a regular maintenance item that will need to be monitored and re-done periodically.

A proper repair to any problematic structures or flashing that cause the problem means the problem should go away for the foreseaable future and you won't have to think about it again any time soon.

The insulated aluminum panels (Styrofoam inner coated by aluminum) of the sun room roof are attached to the fascia about 2 inches below our shingled house roof. Each panel section is 4' x 12'. The leaks have occurred about half way down the seams. We have had several small leaks between the panels. The original roofer of the sun room had come out and supposedly caulked and taped all seams. For some unknown reason that does not make any sense- he drilled a hole next to the seams at the bottom of 2 exterior seam panels. He stated that these holes would release any water between the seams.on the exterior. That did not work- Now, he says that he would need to water down our house roof and the sun room roof to determine if the leaks were caused by our existing house roof leaking which makes no sense at all because each roof is independent of the other as stated by a structural engineer. A rain and ice shield was suggested by the roofer who claims that it would cost me extra- If so, it should have been done before the installation of the sun room roof panels and should have been in his price quote- It is going to cost more for me to sue the roofer of the sun room roof than it would be to repair it- that is why I asked about pulling up the unsightly deteriorated silver tape and re-caulking the exterior seams. I caulked the interior seams where the panels meet and I have had no leaks since then- How could anyone now tell where the water that leaked was coming from? I just want to make sure that if there is any water left in the exterior seams will not mildew or cause any further problems.

Sun rooms like you mention are notorious for leaking and I've helped remove several because of leaks that were never resolved. Yes, you are probably correct in thinking that your house roof is not the cause of the sun room roof leak. It's possible but unlikely but impossible to say without seeing what you have. It is more common that the sun room causes damage to the house's fascia and roof.

Thanks, I will try to get a picture to you- Should I go ahead and pull up the unsightly silver tape and re-caulk the exterior seams again with 30 year guaranteed silicone caulk and see what happens- The new sun room roof looks like crap with all the silver deteriorated tape.

leak

I would say it depends when it comes to taking the tape off. If there is the same amount of leakage even with the tape there, then pulling the tape off isn't going to hurt. But if some of the leakage has stopped since the tape has been put on, then I may hold off on it. You don't want to damage more than what has been done. Hopefully the roofer didn't charge too much to do that. As the others and you yourself have mentioned, pictures would help a lot.

Thanks-Since I have caulked the inside seams with silicone- I have had no leaks. I'll try to get my wife's camera and try to download the picture/pictures and send them your way-
Thanks Again

Tried to post pictures but they are over-sized and I am not going to try to reduce them
