How Often to Reseal RV Roof: A Comprehensive Guide

Owning an RV brings a sense of freedom and adventure, allowing you to hit the open road and explore new destinations at your own pace. However, like any other vehicle, regular maintenance is required to ensure its longevity and performance. One crucial aspect of RV maintenance is resealing the roof. In this article, we will explore the importance of roof resealing, signs that indicate it’s time for resealing, and how often you should undertake this task. Additionally, we’ll answer some frequently asked questions regarding RV roof resealing.

Importance of RV Roof Resealing:

The roof of your RV is constantly exposed to harsh weather conditions, including sun, rain, snow, and extreme temperatures. Over time, these elements can cause wear and tear to the roof, leading to leaks, water damage, and other costly repairs. Resealing the roof helps maintain its integrity, prevents water from seeping in, and ensures the safety and comfort of your RV.

Signs That Indicate It’s Time for Resealing:

1. Water Leaks: If you notice water stains or dampness inside your RV, it’s a clear indication that the roof sealant has deteriorated and needs attention.

2. Cracks and Gaps: Inspect the roof for any cracks, gaps, or seams that are separating. These are vulnerable areas and require immediate resealing to prevent further damage.

3. Missing or Loose Sealant: If you find any missing or loose sealant around vents, skylights, or other roof fixtures, it’s time to reseal them. Neglecting these areas can lead to leaks and water penetration.

How Often Should You Reseal Your RV Roof?

The frequency of resealing your RV roof depends on various factors, such as the type of roof material, weather conditions, and the amount of time your RV spends outdoors. As a general guideline, it is recommended to reseal the roof every 3-5 years. However, it’s crucial to inspect your roof regularly and address any signs of damage promptly, regardless of the timeframe. Additionally, if you frequently travel through areas with extreme weather conditions, it may be necessary to reseal your roof more frequently.


1. Can I reseal my RV roof myself, or do I need professional help?
While resealing your RV roof can be done as a DIY project, it requires careful attention to detail. If you’re comfortable working at heights and have some experience with RV maintenance, you can undertake this task yourself. However, if you’re unsure or lack the necessary skills, it’s best to hire a professional to ensure proper sealing and prevent any further damage.

2. What type of sealant should I use for my RV roof?
The type of sealant you should use depends on the material of your RV roof. For rubber roofs, EPDM-compatible sealants are recommended, while for fiberglass or aluminum roofs, silicone-based sealants can be used. It’s essential to choose a sealant specifically designed for RV roofing to ensure compatibility and long-lasting protection.

3. Do I need to remove the old sealant before applying a new one?
Yes, it’s crucial to remove the old sealant before applying a new one. Use a putty knife or a sealant removal tool to scrape off the old sealant and clean the surface thoroughly. This ensures proper adhesion and prevents any potential issues caused by layering sealants.

4. Can I reseal my RV roof during winter?
It’s generally recommended to reseal your RV roof during dry and warm weather conditions. Cold temperatures can affect the curing process of sealants, potentially compromising their effectiveness. If you must reseal during winter, ensure that the temperature is above the minimum recommended by the manufacturer, and follow their guidelines for application.

5. How much sealant do I need for resealing my RV roof?
The amount of sealant required depends on the size of your RV roof and the condition of the existing sealant. As a general estimate, a 28-ounce tube of sealant should cover approximately 50 linear feet. However, it’s always advisable to purchase slightly more than needed to avoid running out during the process.

6. Can I use duct tape as a temporary solution for a damaged roof seal?
While duct tape may seem like a quick fix, it is not a suitable solution for repairing a damaged roof seal. Duct tape does not provide long-lasting waterproofing, and it can deteriorate quickly under UV exposure or extreme weather conditions. It’s best to address any roof seal issues promptly and properly with the appropriate sealant.

7. What other maintenance tasks should I perform to ensure the longevity of my RV roof?
Besides resealing your RV roof, regular inspections and cleaning are essential. Inspect the roof for any signs of damage or wear, and promptly address any issues. Additionally, clean the roof regularly using mild soap and water, avoiding harsh chemicals or abrasive cleaners that can damage the roof material. Regular maintenance will help prolong the life of your RV roof and minimize the need for major repairs.

In conclusion, resealing your RV roof is a crucial maintenance task that should not be overlooked. Regular inspections, timely repairs, and resealing every 3-5 years contribute to the longevity and performance of your RV. By following these guidelines and addressing any signs of damage promptly, you can ensure a safe and comfortable journey on the open road.
