We have several cottonwood trees, and noticed the bark is loose and falling off. What causes this?
The peeling bark can be a part of the natural aging process of the Cottonwood Tree.
They are not terribly long living trees. The bark sheds and leaves the white underwood exposed and the tree will decline.
They tree can also be suffering from disease or even Winter damage.
If you have several trees dropping bark, examine the tree for any other clues or signs of disease or insects.
Are all the trees of the same size and age?
A certified Arborist can examine the trees and determine the exact cause or if any treatment may be necessary.

I live in Coolidge, AZ., we own a Landscaping business and we just opened a nursery about a month ago, and I’m afraid that we(mostly my husband), are over watering, how much water, for example would a Cottonwood Tree(15 gallon pot) need?
This can be hard to judge, as there are many factors that would affect the daily watering. One days where it remains humid or moist, you can water them less. It is always best to inspect each plant to know whether or not it needs water. Most plants will want the top inch of soil to dry out pretty well between waterings.
I recall as a kid I used the pea sized green "seeds" from our backyard cotton wood tree as ammo for my pea shooter made from a willow branch. These "seeds" looked like exactly like peas but contained a cottony fiber. What is the official name for these "peas"? I recall they hung in clusters. Perhaps my memory is faulty from age.
These peas are the fruit of the cottonwood. If allowed to mature, they open and release the cotton fibers we all know so well.
Can you cut exposed roots without hurting a Cottonwood tree
The simple answer is no, you cannot cut roots without harming a tree.
You can add topsoil to help the situation, it it can be repeated each year.
Many time a homeowner can cover the situation with a ground cover planting.
Here are some articles with more information.

We have a 40 year old cottonwood tree 12 feet from our house. Should it be removed because of the closeness to our house and/or damage to our house foundation? Sincerely, Jean Caskey
Have you noticed any issues with your septic system? This can be tricky. I would have it looked at by a professional tree service to see if they recommend removing it. If the roots are large enough they can do some damage, but there can also be damage done by removing a large tree. Talk to your local tree services to see what they recommend.
My tree don't seem like it's growing. I do water the tree at least 3 times a week. They tell me that these tree's like a lot of water. I dug out some dirt from the bottom of the roots and found a white color stains in the dirt. I wonder if it got a disease? What can I do to correct this problem.
White fungus is, typically, harmless and even beneficial. It could be that it is being overwatered. Even though they do like water, they will not tolerate being saturated all of the time, unless it is a swamp cottonwood, or black cottonwood. They will need a little dry period between watering. I would recommend adding dolomitic lime, and wettable sulfur. This should put the soil back into good condition. These trees will just take patience.
