Aluminum Siding on one side of the house has problems. See the attached pictures. Nails were no longer hitting the studs leaving a space between the siding and the window edges on the second floor. I am using a tape as a bandage solution. This siding is 45 year old and the damage is probably due to snowstorm and strong wind experienced in recent years. This siding is facing north along the walkway to backyard. Questions:

1. the siding has not fallen yet but you can see “cracks” or they are not lying flat on each other (see picture 1). should I ask somebody just put screws to fasten them to each other as a short-term economical solution or must replace the whole area with new siding now?

2. Home Depot staff suggested I use Le Page Construction adhesive to glue the siding back to the wall? Would this be a better solution than putting screws onto the aluminium siding so that it would not create holes? what product would you recommend?

3. The whole area seems loose when you touch the siding. do not see big visible “cracks” in other areas.

4. Picture 3 shows 2 “cracks” in another side of the house. You can see a dark edge at the top of the house/siding. What is it? Are they molds on caulking? Is it easy to clean or fix?

Thank you.
