Imagine the freedom of the open road: a newfound opportunity to explore new destinations and forge lasting memories with loved ones while cruising in your RV. However, this idyllic journey can come to a screeching halt if your RV’s roof springs a leak.

To safeguard your investment and ensure a secure, comfortable voyage, diligent RV roof maintenance is crucial.

In this blog post, we’ll offer tips and tricks on identifying your RV roof material (and how to care for it), along with insights on how to shield the roof of your RV from the elements.

Let’s uphold the pleasure of RVing by tending to our mobile homes with care!

Key Takeaways

  • Use non-abrasive products for rubber roofing material and mild detergent for fiberglass roofs during biannual cleaning.
  • Protect the roof of your RV from the elements with RV covers, vent covers, and coatings/treatments.

Identify RV Roof Material

How you maintain your RV roof will depend on whether the roof is made of rubber membrane (EPDM/TPO) or fiberglass. The chemicals approved for fiberglass roofs could cause damage to EPDM roofing.

Rubber Roofs (EPDM and TPO)

Rubber roofs, including EPDM and TPO, are popular RV roofing materials due to their affordability and durability. EPDM comprises recycled tires, slate dust, and sawdust, while TPO roof is a more rigid and plastic-like material.

To determine if you have an EPDM roof, check if the roof is slick when wet or if the extra material behind one of the roof vent shrouds is black on the bottom and white on top.

If you have a rubber roof, stick with these maintenance tips:

  • Avoid using harsh chemicals or petroleum solvents on an EPDM rubber roof, as they can cause irreparable harm.
  • Use products specifically designed for sealing EPDM roofs.
  • Repair small rips or tears with RV roof sealant to avoid potential water damage.

Fiberglass Roofs

Fiberglass roofs are lightweight and strong, making them a popular choice for RVs. However, they can be susceptible to oxidation and thermal splits, requiring proper care and protection.

These roofs have a smooth, glossy, or semi-glossy finish and slightly reflective texture. The surface is smooth to the touch, unlike some other roofing materials.

To repair a gash or tear in a fiberglass roof, scuff the surface, lay a new layer of fiberglass fabric, and apply resin.

When sealing fiberglass roofs, use a rubbery, silicone-based sealant, which differs from the lap sealants used on EPDM and TPO roofs.

Metal Roofs

Metal roofs, such as aluminum roofs, have a shiny, metallic appearance. When you touch a metal roof, it feels hard and metallic but doesn’t have a textured surface.

You can fix the RV’s metal roof by replacing damaged panels and patching leaks and holes with flashing mate.

The Importance of Regular RV Roof Maintenance

Proper RV roof maintenance prevents potential leaks, mold growth, and costly repairs. Necessary maintenance tasks will vary according to the base material of your RV’s roof (be it rubber, glass fibers, or metal).

With this in mind, understanding your roof type is essential in protecting it from external elements, like extreme temperatures. 

Once you learn your recreational home’s roof type, use these tips to keep it in good shape:

Prevent Mold Growth

Mold growth in your RV can lead to allergic reactions like sneezing, watery eyes, itching, coughing, and difficulty breathing. It can cause structural damage to upholstery, roof, and walls, leading to costly repairs.

To prevent mold growth on your RV root, take these proactive measures:

  • Regularly inspect the roof for signs of water damage, such as discoloration, bubbling, or peeling paint, as it indicates a leak.
  • Fix potential leaks by removing the old sealant.
  • Repair damaged areas with sealant or caulk to prevent water intrusion. Concentrate on roof seams and the areas around roof vents.
  • Keep the roof clean and well-maintained to stop mold growth
  • Regularly wash the roof with mild detergent and water to maintain its good condition.

Protect Against UV Damage

UV damage is another threat to your RV roof, causing drying, cracking, fading, and oxidizing of the roof material. Prolonged exposure to UV rays can even lead to premature roof aging and damage to seals and paint.

To protect your RV roof from UV damage, follow these steps:

  1. Use suitable roof sealants and coatings to create a protective barrier.
  2. Keep your RV covered or opt for indoor RV storage through platforms Neighbor to minimize exposure to the sun.
  3. Clean and inspect the roof regularly.
  4. Install a UV-resistant roof cover or awning for additional protection.

Essential Cleaning Tips for RV Roofs

Clean your RV roof using non-abrasive, non-petroleum-based cleaners and appropriate techniques, such as:

Choose the Right Cleaning Products

Use non-abrasive, non-petroleum-based cleaners for rubber roofs to prevent damage to the rubber membrane.

For fiberglass roofs, opt for warm water and a mild detergent like Dawn dishwashing liquid for gentle cleaning.

In case of stubborn stains on fiberglass roofs, go for commercial cleaning products designed for that specific roofing material.

Proper Cleaning Techniques

Proper RV roof cleaning is vital to prevent damage. Begin by sweeping debris and rinsing the roof. Gently scrub with a medium to soft bristle brush to remove grime, sap, or mildew.

Afterward, inspect for damage and address issues promptly. Following these steps ensures a well-maintained RV roof and prolongs its lifespan.

Inspect and Repair Your RV Roof

Consistent inspection and repair are essential for the trailer’s value preservation. Inspect the roof seams, seals, and caulking around roof vents, skylights, and air conditioning units. You’ll also want to look for cracks, gaps, or areas where the sealant has deteriorated.

If you find any leak, consult your RV owner’s manual for the correct sealant type. Apply it on holes to prevent further corrosion and punctures.

Protect Your RV Roof from External Elements

Shield your RV roof from environmental factors with RV covers, vent covers, and protective coatings. Choose a breathable, snug-fitting cover for UV and debris protection.

To protect against potential leaks and damage to roof components, invest in vent covers.

Keep Track of Your RV Roof Maintenance

Stay up-to-date on RV roof maintenance to ensure your RV remains in excellent condition. To do so, start a maintenance log that includes the date each maintenance task was performed, along with a brief description. 

Inspect your roof at least 3 times a year to record any damage, areas of concern, or potential issues.

Wrapping Up

After completing RV roof maintenance, store your mobile home in secure storage to ensure it stays in optimal condition. You can take it out of the storage whenever you plan to go on your next adventure.
