When you tighten the screws, they should flex the skylight a little but not be so tight that they crack it. (This may involve creating some new holes if they don’t line up perfectly with the existing holes, but don’t worry about making new holes, or not using the olde ones… the sealant will seal them up to prevent them from leaking). To spread the bead out and ensure a complete seal, wiggle the skylight gently until caulk comes up through the screw holes. To do this, use your caulk gun to run a thick bead of Surebond SB140 over the old screw holes along the entire perimeter. Now that you’ve removed the old skylight and the area is clean and dry, you’re ready to install the new skylight on your RV. Be sure not to soak the roofing material too much… you could cause the underlying adhesive to come undone, causing bubbles or other problems with your roof.

Put some mineral spirits on your old rag and use this to clean up the area and remove as much of the sealant as possible. There will be some sticky residue remaining, even after scraping with the putty knife. Next, scrape up any remaining sealant with your putty knife. Remove the old skylight and set it aside. Use caution, especially if you have a rubber roof, so you don’t slice through it with the putty knife. This will allow you to pry it away from the roof. Next, carefully insert the putty knife under the edge of the skylight and slide it around the entire edge all the way around. If you have a rubber roof, be careful to avoid slicing it with the putty knife. While the inner piece is off, you can inspect the upper skylight piece for leaks or cracks. This will allow you to more easily determine the cause of the problem. If you have issues with the interior portion of your skylight, you’ll need to unscrew the interior frame from the inside and remove the entire inner piece.
