How Often Should You Reseal Your RV Roof

How often should you reseal your RV roof? A lot of people are wondering this. There is no easy answer to this question because it depends on how much use the RV is getting and where you live. For instance, if you live in a very hot area like Phoenix, Arizona, or Florida then your roof will need more frequent resealing than someone who lives in a cooler climate like Denver, Colorado, or Seattle Washington.

How Often Should You Reseal Your Rv Roof?

A roof should be resealed each year for the best results. Every ten years the roof should be replaced, as failure to do so may mean that water will leak through your RV and cause damage.

If you’re buying a used RV, there’s a high likelihood that the previous owner did no work to repair, reseal, or replace the roof. However, it is still recommended to check your RV every year.

Why Reseal Your Roof

A leaking roof can quickly become the worst possible nightmare for anyone who owns a model trailer. Not only does it lead to significant water damage and costly repairs, but it should be checked upon regularly by all owners. Trailer owners will want to have the roof sealed at least once a year in order to prevent it from getting worse.

Below are some of the most common causes for leaks in travel trailers.

  • Roof Damage – The most common cause of a roof leak is roof damage due to high winds, tree branches, or weight.
  • Faulty Sealants – As the sealant around vents and other pieces on the roof of a trailer wear down, water can seep in.
  • Aging – As RV ages, it will experience the wear and tear that comes with age. And for travel trailers, in particular, a worn roof can lead to issues such as water intruding into and damaging the interior of your trailer.
  • Loosened Screws – Over time, screws and other attachments can loosen. This space allows water to enter the interior of your roof, causing RV roof leaks.

These are just some of the main reasons roof leaks occur, with no travel trailer. It is important to inspect for these types of leaks before any such damage has had time to accumulate and advance.

How Do I Know if I Need to Reseal My Roof?

To what extent the roof must be resealed on your model of travel trailer depends on the material it is composed of. Consult your owner’s manual to find out which type you have and look up instructions for how best to care for it.

  • Once you have accessed the roof, inspect the seams for any areas that have come apart from the trailer.
  • You can also use a small tool to poke the sealants to test for elasticity.
  • Apply pressure on the sealant and see how it reacts; if it tends back to its original shape, then there is still some life in that material.
