Resealing your RV roof is a key maintenance task that protects your investment from water damage and extends its lifespan. Follow these simple steps to reseal your RV roof effectively and ensure it’s ready for all your adventures.
Why Resealing Your RV Roof Matters
Over time, exposure to the elements causes your RV roof sealant to crack, peel, or deteriorate. Resealing prevents water leaks, mold, and structural damage, keeping your RV in excellent condition. Regular inspections and resealing every 1–2 years can save you from costly repairs.
Tools and Materials Needed
Before starting, gather the following items:
- RV roof cleaner and scrub brush
- Sealant (compatible with your roof type)
- Caulking gun or applicator
- Plastic scraper or putty knife
- EternaBond tape (optional for seams and patches)
- Ladder and safety gear
Step-by-Step Guide to Reseal an RV Roof
- Inspect the Roof
- Look for cracks, peeling sealant, and damaged areas.
- Pay close attention to seams, vents, skylights, and edges.
- Clean the Roof
- Use an RV roof cleaner to remove dirt, debris, and old sealant residue.
- Allow the roof to dry completely before applying new sealant.
- Remove Old Sealant
- Gently scrape away loose or peeling sealant with a plastic scraper.
- Avoid damaging the roof material underneath.
- Apply New Sealant
- Use a high-quality RV-specific sealant like Dicor Lap Sealant or Sikaflex.
- Apply the sealant evenly along seams, vents, and other areas that need resealing.
- For larger repairs, consider using EternaBond tape for a long-lasting seal.
- Smooth the Sealant
- Use a caulking tool or your finger to smooth out the sealant for an even finish.

Why Do We Need to Reseal an RV?
Owning an RV is a fantastic way to explore the outdoors, but maintaining it is essential for long-term enjoyment. One of the most critical maintenance tasks is resealing your RV. Over time, seals can deteriorate, leading to water leaks, structural damage, and costly repairs. Resealing your RV ensures its longevity, protects its interior, and keeps your adventures worry-free.
The Importance of Resealing an RV
RV seals play a vital role in preventing water intrusion. Exposure to the elements, temperature fluctuations, and regular wear can weaken these seals. Without proper resealing:
- Water damage can cause mold and rot.
- Structural integrity may be compromised.
- Resale value of your RV could decline.
By resealing, you maintain a secure barrier against weather and prolong your RV’s lifespan.
How Often Should You Reseal Your RV?
Knowing when to reseal is key. Regular inspections and timely resealing are recommended:
- Inspect annually for cracks, gaps, or peeling.
- Reseal every 1-2 years based on usage and exposure.
- Spot-reseal problem areas immediately to avoid extensive damage.
Staying proactive helps prevent minor issues from turning into costly repairs.
Steps to Reseal an RV Properly
To reseal your RV effectively, follow these steps:
- Clean the surface: Remove dirt, grime, and old sealant.
- Inspect thoroughly: Check windows, doors, roof edges, and seams.
- Apply RV-specific sealant: Use a high-quality product designed for your RV material.
- Let it cure: Allow the sealant to set according to manufacturer instructions.
Always use products compatible with your RV’s construction for the best results.
How Often Should an RV Roof Be Resealed?
