Last week, I talked about cleaning the roof of the RV. This week it will be inspecting and doing minor repairs of the roof. Again, caution should be the word of the day. If your rig does not have an attached ladder, do not climb on the roof, use a ladder to work your way around the roof as you inspect.
First we are going to look for any obvious signs of damage to the roof. If you have used water to clean the roof, look for any puddles where the water pools. These are signs of potential issues and should be watched. Sitting water has time to work its way into the roof even with very minor pin holes. You also want to look for any damaged or pealing sealant around the vents, antennas, fans and air conditioners. Any place where there is a whole through the roofing material.
What to do if you find or suspect an area that should be patched. First using the information from last week, make sure you know what kind of roofing material you have. For the most part EDPM and Fiberglass will use the same materials. You have the choice of tape or sealer.
Eternabond is a tape like product that is used to seal tears and cracks. The only negative is that it can not be used over silicone. So if you have any places that you used silicone to seal, it will have to be removed prior to applying the EternaBond tape. EternaBond is available in widths up to 36 inches so it can be used to cover a large area.
Another product that can be use is a liquid sealer. The most common type is a self leveling sealer that spreads out as you pour it. This naturally is not good for areas around the edge of the rig as it will slide off the roof. But for the flat areas it is good. Use this sealer when you have openings where cables or holes that go through the roof. EternaBond would have problems sealing these areas.
For metal roof repair you can use Quick-Roof. This is similar to the EternaBond in that you peal off the backing and lay down a smooth flat piece (in this case aluminum paper).
