Is this a Double Standard?

Now you all know I love my wife and I would do anything for her, but sometimes she baffles me.  Last night I told her that I met a guy from a roofing company who also cleans off snow from roofs.  I thought, hey why not have him do our garage.  Right now it has two to three feet of snow on it.  He said it would probably cost between 2 to 3 hundred dollars.  Well, when I suggested it, she said we cannot afford it.  At first I argued with her and she said we do not have the money.  I told her I would not get up there, our roof is too slanted and I do not want to fall and break my neck.  She said she would get up there and I told her no, because if I am afraid of falling, then I was also afraid for her safety.  I finally understood what she said about not being able to afford the roofing guys to go up there, so thought of another idea.  I suggested getting a roof rake and my friend Mike found one online at Home Depot for 40 dollars.
Now the plot thickens, she tells Mike, because I am at work, that she does not want to buy a roof rake.  He even tells her he will buy one this Friday, but she refuses.  Right now you are probably asking why I titled this blog post, "Is this a Double Standard?"  Well, before I went to bed at a client's house, because I work third shift sometimes, I reminded Mike to take out the garbage and recyclables.  My wife told him, she did not want him to do this, because it was too icy out.
It was too icy out on flat ground to take out the garbage and recyclables, but she thinks that she is going to get on a forty-five degree angle slanted roof with two to three feet thick of snow and shovel it off.  Good luck, anyway, this is one time I will have to listen to my own instincts and back my friend up.  I will let him buy a roof rake tomorrow and that will be the end.  The necessary good will out way the arguing with my wife when we use the rake and no one falls off to prove a point.
