1. A Step-by-Step Guide to Repairing an RV Rubber Roof

Firstly, let me tell you about the materials that you will need to fix a rubber ceiling:

Tools and Materials

Below is the list of essential tools:

  1. EPDM or TPO sealant;
  2. Rubber patch kit;
  3. Cleaner and primer specific to rubber roofs;
  4. Roller or brush for application.

Step-by-Step Instructions

Now, that you have prepared your roof, let’s move to the mending process. Follow these instructions:

  • Step 1: Apply the primer like Zinsser or Seymour to the dry and cracked area. Use enough amount to completely cover the area with a thin layer. Apply a layer of 6 mm to 12 mm to cover the gaps.
  • Step 2: Remove the extra sealant from the edges. Ensure that you leave at least 1-2 inches around the edges. This will make sure that the seal is leakproof.
  • Step 3: Apply the sealant or adhesive such as Heng’s Rubber Roof Coating and place the patch over the damaged area. I can recommend you apply a layer of 2 mm thick around the surface. For the best result, see the product manual.
  • Step 4: Use a roller to ensure it’s fully bonded. Apply moderate pressure on it for 2-3 minutes.

Allow me to share the fixing method for the metallic roof:

Tools and Materials

Here’s the list of tools required:

  1. Metal roof coating or sealant;
  2. Wire brush for rust removal;
  3. Primer for metal surfaces.

Step-by-Step Instructions

Once you have all the required materials, follow these instructions to fix:

  • Step 1: Clean and remove any rust from the damaged area using a wire brush. Be patient with this step until the rust is gone. You need to set the stage for a durable repair.
  • Step 2: Apply a thin coat of primer of 1 fl. oz. with the help of a roller or brush while thoroughly covering the area. I even extend it 1-2 inches to make sure that the coverage is complete. Let the coating dry.
  • Step 3: Apply the metal roof coating or sealant evenly with a thin coating (around 2 mm) to patch the roof. For the edges, apply a thick 1 cm strip of sealant; think of it as creating a barrier against water ingress.
  • Step 4: Allow it to cure as per the manufacturer’s instructions.

3. A Step-by-Step Guide to Repairing an RV Fiberglass Roof

Let me walk you through the steps to help you fix your roof:

Tools and Materials

To complete this process, this is everything you’ll need:

  1. Fiberglass repair kit;
  2. Gelcoat or fiberglass resin;
  3. Sandpaper for smoothing.

Step-by-Step Instructions

Simply follow these steps one by one to restore your fiberglass rooftop:

  • Step 1: Clean the damaged area thoroughly. I find a soft brush to work best for that initial debris cleanup as it is not too rough on the fiberglass. You can also use a degreaser like Heavy Duty Degreaser for a squeaky clean wipe-down.
  • Step 2: Apply the fiberglass resin and place the fiberglass mat. Place moderate weight with a roller on it so that the patch bonds without air bubbles even if the temperature is cold.
  • Step 3: Once cured, apply a layer of gel coat for a smooth finish (0.5 – 1 mm in thickness). I prefer glue for initial placement and then apply a coat of thin sealant (half and 1-inch thick layer) to waterproof it. Using the same color gel coat gives it a seamless finish.
  • Step 4: Sand the area until it blends seamlessly with the surrounding roof. I have found wet sanding provides a better glossy finish.

How to Gloss Up Fiber Glass Roofing Material

Here I am going to list the easy steps if you want to maintain the gloss:

  1. Start applying the wax in a circular motion.
  2. Use a soft micro-fiber cloth to rub the wax.
  3. Let it completely dry and buff out any excess so that the surface is smooth and shiny.

Alternatively, you can also use this method:

  1. Using toluene, remove the wax from the roof.
  2. Apply a rubbing compound to the glass in a circular motion and buff it to make it shine.
  3. Repeat the above process to restore the shine.

Should I Buff the Roof with my Hand or Use an Electric Buffer?

Buffing an RV roof depends on what you prefer, but I feel using the electric buffer saves a lot of time and effort and doesn’t leave your hands sore the next day!

Tip: While some roof repair products on the market claim to restore the shine of gel coat and make it look brand new, From my personal experience, the result may look astounding, but only for the short term. After some time, the glass loses that lustrous look.

How to Replace and Renew an RV Rotted Wood Pallet

Now, I will share a guide on how to replace a rotten RV wood roof. As someone who has spent my given share of hours under the sun repairing my RV pallet wood, let me walk you through the steps based on what I have experienced:

  1. Careful Inspection: First of all, you need to ensure which parts of wood need replacement. Using a screwdriver or knife, poke the wood and see how deep the rot goes. You can also mark the area with a pencil or tape for precise removal.
  2. Removing Rotten Wood: After you have identified the faulty area, use a hammer or chisel to remove it. Always work from outside so that you don’t cause damage to the structure. With the help of any duster or vacuum cleaner, remove the dust, debris, or mold.
  3. Measuring Rotten and New Wood: With the help of a tape measure or ruler, calculate the dimensions of rotten wood, including the depth. Now, cut a new piece of wood with the help of a handsaw or jigsaw according to the same dimensions and place it. I always leave a few mm around the edges for a snug fit. Use a sandpaper to smooth the edges.
  4. Securing in Replaced Wood: Place the new wood in the spots and secure them properly using screws and nails. I prefer screws for a more secure fit as they provide more durability against vibrations and shocks while on the road!
  5. Caulking and Sealing: Religiously caulk the new wood pieces to hold them in place with the help of a caulking gun such as the DEWALT 20V MAX Caulking Gun. Secure the replacement with a sealant like Sashco Caulking sealant with a clean finish to avoid water leakage.
  6. Finishing: Apply a new coat of varnish on top of the pellets to match the color. You can use any varnish such as Liquitex BASICS Varnish. Apply the first thin coat and let it dry. The application rate should be 1 fl. oz. to 7 sq. ft. After 24 hours of application, sand the first coat with sandpaper and apply a second coat. Let it dry for 24-48 hours. This will not only protect the wood but will also give a uniform look to the new roof.
Pro-Tip: Treat the wood with anti-mold and fungal treatments to prevent rotting in the future.

Your RV is more than just a vehicle, it’s your home on the wheels! So take care of it. Watch this video to learn how to install rotten wood pellets to repair your RV roof.

Top 8 Tips & Tricks To Prolong Your RV Roof

The key to extending the life of your RV roof lies in the heart of regular maintenance. Let me share 8 helpful tips with you:

  1. Inspection: Regularly inspect your roof every three months for any cracks, leaks, tears, or loose seams which will help to catch up to any issue before things escalate.
  2. Cleaning: Seasonally clean the roof with mild soap and RV roof cleaner and let it completely dry to avoid water damage.
  3. Steer Clear from Harsh Chemicals: Stay away from any chemicals and abrasive cleaners that will ruin the roof and make it more susceptible to damage. I would recommend you try out Biokleen roof cleaner for the best results.
  4. Debris removal & Gutter maintenance: Regularly remove any debris, dust, leaves, and branches from the top and the gutters. These can trap moisture and leave a stain on the roof from their sap. Water pooling can lead to more exposure to leaks and mold.
  5. Sealant application: You may use a protective coat of roof sealant up to 2mm to protect against UV rays. This will provide an extra level of protection and extend the life warranty of the material.
  6. Weight management: Try to avoid putting any weight on the rooftop, as these materials are not designed to carry a large weight and may wear and tear. Any kind of excessive load can cause structural damage to your roof. Use a strong ladder leaned against the wall to avoid putting pressure on the roof.
  7. Storage: When the RV is not in use, always park it indoors or in shade to minimize exposure to sunlight and harsh weather. Proper storage of your RV will help it from getting premature signs of aging like discoloration and paint withering.

The Breakdown of Average Cost to Replace an RV Roof

Now, it’s time to discuss the expenses. Here is an estimate of how much it will cost to replace your roof:

1. Material Cost:

The material cost can vary depending on its type:

  • TPO: These will cost around $5.50 to $6 per square foot. They are UV-resistant, long-lasting, and energy efficient.
  • EPDM: This rubber membrane is durable and cost-effective, costing you $4 to $8 per square foot.
  • Fiberglass: Though heavy and expensive, they are low-maintenance and long-lasting, costing up to $2 to $4 per square foot.
  • Aluminum: It is low-maintenance and recyclable but can be a bit heavy and costs around $3 per square foot.
