This guide will walk you through exactly how to reseal a camper roof, ensuring that you’ll be watertight and road-ready. Whether you’re an experienced camper owner or a newbie to the RV lifestyle, this step-by-step tutorial has got you covered—pun intended!

Why Resealing Your Camper Roof Matters

The roof is your camper’s first line of defense against the elements. Over time, UV rays, rain, and fluctuating temperatures can break down the seals and materials. If the roof isn’t sealed properly, water can seep in, leading to costly damage like wood rot, mold, or ruined interiors.

Regular maintenance of your camper roof, including resealing every few years, is essential to prolong its lifespan and protect your investment.

Tools You’ll Need to Reseal a Camper Roof

Before you start, you’ll want to gather all the necessary tools and supplies. Here’s what you’ll need:

• Ladder or scaffolding: To access the roof safely.
• Rubber roof cleaner or mild detergent: To clean the surface.
• Soft-bristled brush or mop: For scrubbing the dirt away.
• Sealant remover (if needed): For removing old, cracked sealant.
• Rubber roof repair tape or patches: To cover minor tears or damage.
• RV roof sealant (self-leveling or non-sag): Choose one compatible with your roof material (EPDM, TPO, metal, or fiberglass).
• Caulk gun: For applying sealant easily.
• Protective gear: Gloves and safety glasses.
• Plastic scraper or utility knife: To carefully lift old layers of sealant.

Pro tip! Make sure to verify your camper roof material type before purchasing sealants and cleaning products. Common roof types include rubber (EPDM or TPO), fiberglass, and aluminum.

A Step-By-Step Guide to Resealing Your Camper Roof

Step 1: Inspect the Roof

Start by carefully inspecting the entire roof of your camper. Look for signs of:

• Cracks, tears, or holes in the roof material
• Worn-out seals around vents, AC units, or skylights
• Mold, dirt, or debris that needs to be cleaned

Mark damaged areas with tape or a marker so you can address them later.

Step 2: Clean the Roof Thoroughly

Cleaning is a crucial first step—proper adhesion of the new sealant depends on a clean surface.

• Use a rubber roof cleaner or mild detergent mixed with water.
• Scrub the surface with a soft-bristled brush, removing dirt, debris, and mildew.
• Rinse thoroughly and give the roof ample time to dry completely.

Avoid abrasive tools that could damage your roof material during cleaning.

Step 3: Remove Old Sealant

If the existing sealant is cracked, peeling, or damaged, remove it before applying a new layer.

• Use a plastic scraper, utility knife, or sealant remover.
• Work slowly and carefully to avoid scratching the roof surface.

For stubborn or thick sealant, soften it using a specialized RV-safe solvent, and wipe away residue with a clean cloth.

Step 4: Repair Any Damage or Tears

For small tears or holes in the roof, patch them with repair tape or patches before resealing:

• Measure and cut the repair tape to cover the damaged area.
• Apply the tape and press firmly to ensure it sticks well.
• Smooth out any air bubbles or wrinkles.

If the damage is extensive, consult a professional before proceeding.

Step 5: Apply New Sealant

Now it’s time to apply new sealant around all vents, skylights, seams, and edges:

• Use the caulk gun with the RV roof sealant.
• If you’re using self-leveling sealant, it’ll naturally spread to cover gaps.
• For non-sag sealant, spread evenly using a finger or spatula to ensure a proper seal.

Take your time and double-check that every seam and edge is properly sealed.

Step 6: Allow it to Cure

Allow the sealant to cure for the time specified on the manufacturer’s label. This could take a few hours to a couple of days depending on the product. Avoid driving or exposing the roof to water during this time.

Once the sealant has cured, inspect the roof to ensure full coverage and make adjustments if needed.
