Drip edging for Class C window

Whenever rain or snow melt runs off the roof and down my side window, the water comes inside through the bottom track of the window. If there is enough it overflows down the wall.

To reduce this problem I installed a drip edge above the window. I got the 1-1/2 inch edge at Lowes for a few dollars. Painted it with two coats of primer and three coats of almond spray paint. Installed with stainless steel sheet metal screws and Dicor (non self-leveling type so it does not drip).

I should have installed the edging temporarily, applied masking tape above it, removed the edging, and finally applied the Dicor. This would have been a cleaner installation, but it worked out OK.

    They still sell the aluminum pieces that go over the windows or doors. They come in different lengths. I bought a 48 Inch piece last year. It was light as heck. The piece curves downward on each end. Forget where I bought it but a google search should work. Was not expensive at all.

  • How your Rv is leveled has a lot to do with how much water comes into a window thru the weep holes.

    I found out in a rain storm when the weep holes in the window could not keep up with the amount of rain coming down one side of my MH....was due to the fact that my MH was ever so slightly tipped to that side. I got out and leveled it and the water coming in immediately stopped.

    What I do now especially if traveling during rainy season is when I level the MH I raise the 'front' ever so slightly up so all the water runs off the back and NOT to either side over any windows. You will not notice it but that little bit makes a big difference for the water run off.

    Many of RV'ers have been talked into replacing windows when all it really was is the RV not level and the weep holes not being able to keep up with the excess water from the roof flowing over that one side.
  • Have you ever removed the window frame and replaced the butyl tape - your rig is old enough that it's something you probably should do on all of your windows. Lots of Youtube videos on how to perform - easy task.
  • Interesting. I just went out and looked and there are no drain holes at all. The gaskets are just not as tight as they were 20 years ago.

    As always just tossing this out for consideration and your mileage may vary.
  • Sounds like the drain holes in the window are plugged or, and I have run into this, the window is in upside down
