Owning an RV is a joy—it’s your home on wheels, taking you wherever adventure calls. But like any home, your RV needs care, and one critical area that often gets overlooked is the roof. Whether you’re a weekend camper or a full-time RVer, keeping your roof resealed is essential for protecting your RV from leaks and weather damage.
This guide will walk you through everything you need to know about resealing your RV roof. From cleaning and inspecting to choosing the ideal sealant and applying it like a pro, we’ve got you covered.
Why Resealing Is a Lifesaver for Your RV Roof
Your RV roof is your first line of defense against the elements. Over time, exposure to sun, rain, and temperature fluctuations can wear down the sealant, leaving your roof vulnerable to cracks, leaks, and water damage.
Resealing your roof regularly not only prevents costly repairs down the line but also extends your RV’s lifespan. Think of it as giving your RV a protective shield—one that can handle whatever nature throws your way. Experts recommend resealing your RV roof at least once a year or whenever you notice weak spots forming.
Benefits of Resealing Your RV Roof
- Prevents water damage: Avoid costly repairs caused by leaks and mold.
- Enhances durability: Protects the roof material from wear and tear.
- Improves resale value: A well-maintained RV roof is a big selling point.
- Saves money: Routine maintenance reduces the chance of needing major repairs.
Sound good? Great. Now, let’s talk about the how.
Gather Your Supplies Like a Pro
Before you start, it’s important to have the right tools and materials on hand. Here’s a checklist to ensure you don’t miss anything mid-project.
What You’ll Need
- Mild detergent and a scrub brush for cleaning
- Pressure washer or garden hose
- Ladder (ensure it’s stable and safe!)
- Caulking gun if you’re using tube sealant
- RV-specific roof sealant like Dicor or EternaBond
- Putty knife for removing old sealant
- Rags and gloves to keep your hands clean
- Painter’s tape for clean application lines
Got everything? Perfect—time to get started.
Step 1: Clean It Like You Mean It
A clean surface is key to ensuring the new sealant adheres properly. Start by removing any dirt, debris, and old sealant.
- Use a scrub brush and mild detergent to clean the entire roof. Pay special attention to areas around seams and vents, where buildup can occur.
- Rinse thoroughly with a pressure washer or hose and allow the roof to dry completely. Moisture can prevent the sealant from sticking, so don’t rush this step!
Pro Tip: Work on a sunny day to speed up the drying process.
Step 2: Inspect for Trouble Spots
Take your time inspecting the roof for any signs of damage. Common issues include cracks, holes, and worn-out areas where the old sealant has deteriorated.
- Pay extra attention to seams, corners, and areas around vents, skylights, or air conditioners.
- Carefully remove any loose or peeling sealant using a putty knife. If you find significant damage, it’s worth consulting a professional before proceeding.
Step 3: Choose the Right Sealant
Not all sealants are created equal. Picking the right one for your RV’s roof material is crucial to ensure long-lasting protection.
Types of RV Roofs and Recommended Sealants
- Rubber (EPDM or TPO): Use Dicor self-leveling sealant or EternaBond tape.
- Fiberglass: A silicone-based sealant works best.
- Aluminum: Opt for acrylic roof sealant.
Check your RV’s manual or existing roof documentation if you’re unsure about the roof material.
Pro Tip: Always use a sealant specifically designed for RVs—you don’t want to skimp on quality here.
Step 4: Apply Like a Total Boss
With your surface prepped and the right sealant in hand, it’s time to get down to business.
- Tape Off Edges: Use painter’s tape to mark the areas you’ll be sealing. This ensures a neat finish.
- Apply Sealant: If using a tube sealant, load it into a caulking gun and apply an even bead along seams, cracks, and around fixtures. If using tape, press it down firmly, smoothing out any air bubbles.
- Smooth It Out: Use a putty knife to spread the sealant evenly, ensuring all gaps are thoroughly sealed.
Work methodically, one section at a time, and avoid stepping on areas you’ve just sealed.
Don’t Forget to Let It Cure!
Patience is key here. The sealant needs ample time to cure and harden fully. Curing times can vary based on the product and weather, so check the manufacturer’s instructions.
Typical Curing Times
- Dicor sealant: 4-6 hours to skin over; 30 days to fully cure.
- EternaBond tape: Immediate adhesion but allow 24-48 hours for full bond.
During this time, avoid exposing the roof to water or extreme weather conditions.
Common Mistakes to Avoid (Oops!)
Even the most seasoned DIYers can make mistakes. Watch out for these common pitfalls to ensure your resealing job is flawless.
- Skipping the cleaning step: Dirt and debris prevent proper adhesion.
- Applying too much sealant: More isn’t always better—apply a thin, even layer.
- Using the wrong sealant: Make sure it matches your roof material.
- Rushing the curing process: Patience pays off. Don’t cut corners here!
