Last winter I had some FRIGGIN MICE get into my popup and ate some holes in the canvas. This year I have a different popup and I didn't park it next to my shed 'cause mice are supposed to go back to the same place every year????? I don't know but I figure I will leave it on the side of my driveway this winter. Besides I had it out to go camping in January and I would never have gotten to it with all of this snow. I did shovel the roof after every storm so the snow did not sit on the roof. I have been opening it up and checking on it every few weeks. I have noticed it was getting a little more difficult to crank it up. I figured I just need to grease the cables or something. Every time I open it I have been checking the roof for leaks. The roof was moist in the front in October so I recaulked all of the seams and that seemed to work, but I still check it. This past Sunday I'm checking it out and dreaming about going to RICKETTS GLEN at the end of April and I'm feeling the roof. Seems solid and dry. Then I play with it a bit more and I see it is a little moist. I think I caught it before any major damage was done but I think I now need to seal the center seam of the roof (it is a pre ABS 2 piece aluminum roof) What is the fix for now....A tarp. I put something on the roof to form a peak and threw a tarp over it and tied it down. How do I dry the roof? I was thinking of putting some of those moisture absorber cans from home depot in the popup. Do you think they need to be on top of the bunks in order to work? I was also thinking about opening it up and putting a de humidifier in there. How do I seal the center seam? I see that there are a million screws holding it down, is it just a matter of unscrewing them all and the trim piece comes up? Then clean the old smutz off and put some new caulking on it? I really think the roof is salvagable. No damage seems to have been done, the roof is still solid, just wet. I am not rebuilding the roof, so that is NOT an option. I have skills, just not enough to redo a whole roof. Plus I don't have the time or space.
