What would cause blue painters tape to remove paint from aluminum siding?

-Two years ago I hired painters to paint my vinyl siding house. The front, back, and sides of the house and shop were pink. I hated it, so I decided to paint it taupe. The paint was Super Paint from Sherwin Williams, and I hired painters to do it. This summer I went to touch the paint up, so we could put the house up for sale; and the paint no longer matched. It had faded and lost it's sheen. Sherwin Williams sent a sample of the paint to a lab, and found one of the tints in it was defective; which caused it to wash out. They had three painting companies come out and give estimates. They said they were the best of the best. Then they chose one of the three. They came out one day and washed the house down. Then they came back to prepare the house to spray paint it. They covered the windows and eves with paper, using blue painters tape. Then it rained every day for nearly a week. Then they came out and sprayed on the first coat. I stayed up most of that night on my computer. I kept smelling something that smelled like chemicals. It completely stopped up my sinuses. Then I got a horrible headache. The fumes were really strong, especially in the rooms across the back of my house. The next day they came and sprayed the second coat. After that the paper and painters tape was removed. When the blue tape was finally removed, it took the paint off of the aluminum siding that's around the windows on the back and side of the house and on our shop. It barely effected the trim on the front of the house at all. The aluminum siding trim came painted from the factory with a coat of white paint, and now silver strips are showing all around the windows from the white paint being removed. This house was built in 1999. We have never painted the aluminum trim. Now they have to sand and repaint all that aluminum trim. This painter charged Sherwin Williams $4,000 and Sherwin Williams supplied all the paint. They're providing the most expensive paint they sell; which would have cost at least $1,000 if I had bought it. I call this our $5,000 paint job. This painter said he had never seen or heard of anything like this happening before. I am assuming this happened because the tape was left on too long, and then wasn't removed correctly. There wasn't enough paper put under the eaves of the house, either. There is over spray on the vinyl. The painter intends to touch it up with paint. He also got over spray on my patio. He heard me say something about touching some spots up on the patio myself. He told my husband, "Well, your wife said she was going to paint it anyway. I'll give you a good price to do it." I had to sign a release from Sherwin Williams before the job could even be done. I am livid! He is suppose to come back this week to put the shutters back up. He said he's going to fix the paint on the aluminum siding, but he didn't say whether there would be a charge or not. Please tell me this was caused from leaving the blue painters tape on way too long and then wasn't correctly removed. Shouldn't he be responsible for the damages, and shouldn't he fix the aluminum siding and paint my patio without charge? What about the overspray under the eaves? Can this be removed without having to paint the eaves? That area of vinyl is white and has never been painted. I would like to leave it that way. He is probably planning on just touching it up here and there. Won't it change colors over time and all of it eventually need to be painted? He is suppose to be a professional. I don't understand, especially when his company is suppose to be one of the "best of the best".Wow looks like you have had quite an ordeal. The only reason I could think that would happen is incorrect removal of the tape. Generally when siding comes coloured from the manufacturer it is factory sprayed which rarely comes off, unlike painting yourself. The tape should not have been left on so long and should have been carefully taking off. As for the vinyl, the no other option really other than spot painting because strippers don't always work and may harm the vinyl. But over time or even right away the spot painting will most likely be noticeable, even if it is the exact same colour white and sheen. Depending on the specific paint used the colour changes over time. Oil based paints tend to yellow and latex sometimes cracks. This happens a lot with paint that doesn't have UV protection in it or gets a lot of moisture over time. I would defiantly get him to do the patio for no charge. He is suppose to be the professional and when they make mistakes it's gotta cost them. Especially a mistake like over spray. That's a mistake for a beginner to make.
the original paint that was on the alum came off. it should not have come off if that was painted on the alum from the factory, That stuff is usually baked on and never comes off, so i believe that the reason it came of with the tape is because the paint had poor adhesion to the alum. When tape is left on too long the problem you have is getting the tape of without it tearing and leaving adhesive on the paint. When paint comes off, it is always an adhesion problem with paint it was applied too.

Just so know . The way paint adhesion properties is tested in labs is using tape . They put tape with strong adhesive and pull it off. if some paint comes off , it failed the test.

Your painters can not be held responsible for the poor adhesion of the original paint. But it sounds like they will try and repair it anyway.

The over spray is all on them. I have NEVER under stood how or why spray painters think that over spray is acceptable . it is not. They could have gone behind themselves and cleaned the overspray off before it dried completely.
