Why Do RV Roofs Leak?
Rook leaks are an unfortunately common issue on many RVs. If you drive an RV that's more than a few years old, then you'll likely experience this problem at some point in the lifespan of your vehicle. Like your home's roof, your RV's roof must resist the elements day-in and day-out. Unlike your home, your RV must also contend with the wear and tear that comes from traveling over uneven and rough roads.
A roof leak is more than just a minor annoyance, however. In many cases, leaks may go unnoticed for weeks or longer. Water can cause significant interior damage and may even affect your motorhome's electrical system. Since leaks can be so costly, it's crucial to understand why they occur, what you can do to prevent them, and how to deal with those you cannot stop.
Common Causes of Roof Leaks
In most cases, RV roofs leak due to failures in the sealant or coating. The underlying roofing material can often last for decades or longer if well-maintained, but this doesn't mean that you won't experience any leaks. Exposure to the elements can wear out the sealant, allowing water to find its way into small gaps between panels. Protrusts such as air conditioner units are another common source of sealant leaks.
Many owners first discover leaks after severe storms, but this usually isn't the direct cause of the problem. Instead, these leaks typically occur at points where the sealant was already failing. Heavy rain or strong winds can drive water into these weak spots, whereas light rain may fail to penetrate the interior. In some cases, the leak goes unnoticed until the volume of water is high enough.
Preventing and Repairing Leaks
Although you almost certainly can't prevent every leak, you can reduce their occurrences and avoid damage when they do crop up. The key to prevention is to avoid exposing your roof sealant to the environment more than necessary. While the best prevention comes from keeping your roof dry, out of the sun, and in a temperature-controlled environment, this level of protection is rarely feasible.
Instead, focus on covering your RV when it is not in use. By keeping the sun's rays off the roof, you'll maximize the lifespan of the sealant. A covered parking area also keeps water off the roof, reducing the likelihood that you'll suffer severe water damage while the RV is unattended. Frequent inspections will also help to ensure you don't experience a damaging leak while your vehicle is unattended.
Once you find a leak, you can usually repair the problem by applying new sealant. Always thoroughly check your interior for additional damage after a leak, however. Any water that you miss can lead to mold growth or other serious issues. By protecting your RV's roof and immediately repairing damage when you spot it, you can ensure that your vehicle will provide you trouble-free enjoyment for years.
