Top 5 Best Sealers for Camper Roofs
1. Dicor Lap Sealant Self-Leveling
Dicor Lap Sealant is a trusted name in RV maintenance. It’s specially formulated for EPDM rubber roofs, which are common on campers. This self-leveling sealant creates a watertight seal around vents, skylights, and other roof fixtures.
Pros:
- ✅ Self-leveling formula fills gaps easily
- ✅ Excellent adhesion to EPDM rubber roofs
- ✅ UV resistant, preventing cracking and discoloration
Cons:
- ❌ Can be messy to apply
- ❌ Limited color options (usually white or gray)
- ❌ Not ideal for vertical surfaces
Verdict: If you have an EPDM roof and need a reliable sealant for vents and seams, Dicor Lap Sealant is an excellent choice.
2. Geocel Pro Flex RV Flexible Sealant
Geocel Pro Flex RV Sealant is known for its flexibility and strong adhesion. This makes it perfect for sealing joints and seams on RVs and campers that experience a lot of movement. I’ve used it on fiberglass and aluminum with great results.
Pros:
- ✅ Highly flexible, resists cracking and peeling
- ✅ Strong adhesion to various surfaces, including fiberglass
- ✅ Paintable, allowing for color matching
Cons:
- ❌ Can be difficult to smooth out

Verdict: For those needing a sealant that can handle movement and different materials, Geocel Pro Flex RV Sealant is a solid choice.
3. EternaBond RoofSeal Tape
EternaBond RoofSeal Tape is not a sealant in the traditional sense, but it provides an incredibly strong and waterproof seal. It’s basically a super-sticky tape that bonds permanently to almost any surface. It’s my go-to for quick patches and repairs.
Pros:
- ✅ Extremely strong adhesion, creating a permanent bond
- ✅ Easy to apply, no special tools required
- ✅ Works on a wide range of materials
Cons:
- ❌ Can be expensive for large areas

4. Liquid Rubber Waterproof Sealant
Liquid Rubber Waterproof Sealant is a coating that creates a seamless, waterproof membrane over your entire roof. It’s a bit more involved to apply than a traditional sealant, but the result is long-lasting and highly effective. I used this on an older camper and it extended its life significantly.
Pros:
- ✅ Creates a seamless, waterproof membrane
- ✅ Excellent UV and weather resistance
- ✅ Can be applied to a variety of surfaces
Cons:
- ❌ More expensive than traditional sealants
- ❌ Requires more prep work and application time
- ❌ May require multiple coats for full protection
Verdict: If you’re looking for a long-term solution to protect your entire camper roof, Liquid Rubber Waterproof Sealant is an excellent investment.

Alpha Systems 1021 Self-Leveling Sealant is a budget-friendly option for sealing gaps and seams on your camper roof. It’s a self-leveling formula that provides a watertight seal, similar to Dicor, but at a lower price point. It is a good option if you are looking for a quick fix.

Buying Guide
Choosing the right sealant for your camper roof can feel overwhelming, but here are a few things to consider:
- Roof Material: Different sealants are designed for different materials. Make sure the sealant you choose is compatible with your roof (EPDM rubber, fiberglass, aluminum, etc.).
- Type of Seal: Do you need to seal a small gap, a large seam, or coat the entire roof? This will determine whether you need a lap sealant, flexible sealant, tape, or liquid rubber coating.
- Weather Conditions: If you live in an area with extreme temperatures or heavy rain, choose a sealant that is specifically designed to withstand those conditions.
- Application: Consider how easy the sealant is to apply. Some sealants require special tools or preparation, while others are simple to apply with a caulking gun or brush.
- Budget: Sealants range in price from affordable to quite expensive. Determine your budget and find a sealant that meets your needs without breaking the bank.
- Read Reviews: Check out what other RV owners are saying about different sealants before making a decision. Real-world experiences can be invaluable.
