Problem 1: Leaking Rooftops

Like most other RVs, the Jayco Seismic has a rooftop made of wooden frames. However, these structures aren’t waterproof, causing the water to seep in when it rains. This makes the wood very susceptible to rot. In addition, it can also be incredibly annoying as the water drip sounds can create echoes.

There could be plenty of reasons which can cause your Jayco Seismic’s rooftops to leak water. You can take a glance below to find the list of some of the most common causes. 

• Gaps at the edges of the roof are too large
• Wooden rooftops can rot and disintegrate quite easily.
• Rooftop isn’t waterproof, so it allows the water to seep inside
• Wooden frames aren’t reinforced
• Trailer itself is very old

To fix a rooftop, you must make sure to first patch up all the nooks and crooks through which water can find its way. In addition, make sure to get rid of any rot that can damage the good parts of the wood. 

When you are done with getting rid of the rotten grains, reinforce the ceilings with a waterproof plaster or cover. Waterproof Scotch tape should also do the work well. 

How Much Does It Cost To Fix Leaking Rooftops On Jayco Seismic?

You will need to spend around 10 to 30 USD to get your hands on a patch of decent waterproof scotch tape. If you are going to use any other waterproof sheets, the typical cost might be around 20 USD.
