Have can be followed by object + past participle. This structure is used to talk about causing or getting things done.
We must have the roof repaired before Easter. (= We want the roof to be repaired before Easter.)
I must have that deadline extended by a few days. (= I want the deadline to be extended by a few days.)
I am going to have my car repaired next week.
I think you should have that carpet cleaned.
This structure is also used to talk about things happening to us. Note that in this case, the meaning is always passive.
I had my car stereo stolen last week. (= My car stereo had been stolen.)
The convict had his head cut off. (= His head was cut off.)
We had to have our dog put down because of his terminal illness. (= Our dog had to be put down.)
Note that it is usually possible to express the same idea using get + object + past participle.
I think you should get that carpet cleaned.
You should get your eyes examined by a qualified ophthalmologist.
You must get your hair cut.
As you can see there is little or no difference between these two structures.
You ought to have your eyes examined. = You ought to get your eyes examined.
