Recently, I had a very similar experience. Ugh. I had knocked off one of the clearance light covers over the driver's side while washing the coach using a pole mounted microfiber wash mop. Several days later when I climbed the ladder to replace the cover, I noticed that my driver's side windshield upper corner had popped. Needless to say, I was surprised that I hadn't noticed this from the ground.
Just yesterday, I had an appointment at RV Glass in Coburg, OR where the technicians removed and reset the glass. I would advise that you have a reputable glass shop take a look at your situation. A popped windshield could be an indication that something else is going on. In my case, my glass had been replaced by a coach restoration shop last summer after they broke the original glass that had been in place since the coach was new. Their install was substandard and just didn't hold. As was explained to me, Monaco was not always 'exact' with the dimensions of the windshield opening in the front cap. My original glass survived almost 9 years of service. But when broken and subsequently removed, the new glass apparently did not fit perfectly. Observations of large amounts of sealant were evidence to that. RV Glass determined that the top of the opening was not straight and true and required approximately 1/8" ground off along a portion of the top. So in my case, I am glad I reached out to a shop that I could trust. Best of luck.
