A healthy roof is key to keeping your RV on the road. Aside from your routine roof maintenance, the secret to keeping your roof in good shape is understanding the material it’s made of. This knowledge can also be helpful if you’re looking to replace your RV roof with something a little different.

Different types of RV roofs have different advantages and drawbacks, so we’ll walk you through the different options on the market. We’ll be looking at EPDM rubber, TPO rubber, fiberglass, and aluminum so that you can see which one is best for your RV.

Key Takeaways

• EPDM rubber roofs are affordable and DIY-friendly, but absorb heat.
• TPO offers better heat reflection at similar costs to EPDM.
• Fiberglass lasts 25-30 years with minimal maintenance, but costs $9,000-$15,000 to replace.
• Aluminum RV roofing material is rare, but it's nearly indestructible and perfect for vintage builds.

What Are the Main Types of RV Roof Materials You Can Choose?

Four primary materials dominate the RV roofing market: EPDM rubber, TPO rubber, fiberglass, and aluminum, each with distinct costs, lifespans, and ideal use cases. We’ll cover each of them below:

EPDM Rubber RV Roofs

EPDM (Ethylene Propylene Diene Monomer) rubber is a stretchy, membrane-based roofing material that costs $4-$8 per square foot and lasts 20+ years with proper maintenance.

EPDM is lightweight, durable, and forgiving. The rubber is soft and elastic, so debris bounces off rather than denting your roof.

Additionally, the installation is straightforward enough for a weekend DIYer. Materials for an average 250-square-foot roof run $1,000-$2,000, and if you tackle it yourself, you'll save thousands compared to professional installation.

But here's the catch: even white EPDM absorbs a lot of heat. If you're RVing in Arizona or Florida during the summer, your air conditioner will work overtime. EPDM is also vulnerable to punctures, though specialized tapes like Eternabond make repairs relatively simple.

EPDM is best for: RVers who value DIY maintenance, want to save money, and spend most of their time in northern climates or cooler seasons.

FOR THOSE NOT-SO-SUNSHINY DAYS

It’s not always smooth sailing on the open road. Learn how RV insurance through Roamly can protect you on a rainy day.

TPO Rubber RV Roofs

TPO is a single-ply white roofing membrane that reflects heat similarly to fiberglass or aluminum but costs significantly less. The white finish isn't just aesthetic. It keeps your RV cooler, which means lower energy bills and a more comfortable interior in hot weather.

The TPO lifespan typically ranges from 20 to 30 years, with an average of around 24 years. The material is UV-resistant, impact-resistant, and can withstand all four seasons without issue.

The downside? Quality varies significantly between manufacturers, and TPO degrades more rapidly than fiberglass or aluminum, despite the application of protective coatings. Hence, you'll need to seal it with a waterproof, UV-resistant coating right after installation.

TPO is best for: RVers who want affordable, heat-reflective roofing that works in all climates and don't mind regular maintenance.

KEEP YOUR AWNING FRESH

Your RV awning is an extension of the roof and allows you to bring the comforts of your RV to the outside world! Keep your awning clean and ready for the next sunny day with these tips.

Fiberglass RV Roofs

Fiberglass RV roofs cost $9,000-$15,000 to replace but last 25-30 years with minimal maintenance. It's typically installed on RVs where the walls match the roof material, creating a cohesive look.

The durability is hard to beat. Fiberglass won't crack under normal use, it's completely waterproof without sealants, and it won't rust or break down like rubber roofs. The lightweight construction also helps with fuel economy. Fiberglass roofs are fire-resistant and completely resistant to mold and mildew, which matters if you store your RV in humid climates.

But fiberglass isn't perfect. Professional replacement costs are expensive due to the complexity of working with the material, and repairs aren't DIY-friendly. Fiberglass also lacks heat resistance. In hot climates, the material expands and can develop thermal splits that require expensive repairs. So you'll need excellent insulation underneath to compensate.

Fiberglass is best for: Full-timers who want set-it-and-forget-it reliability and have the budget for premium materials.

SAVE MONEY AND ENERGY BY INSULATING

Aluminum RV Roofs

Aluminum RV roofs are the rarest and most durable option, featuring longevity and superior puncture resistance, though they dent easily, conduct heat poorly, and require professional installation.

You won't see many aluminum roofs on modern RVs, but there's a reason vintage Airstreams still sport their original roofs 50+ years later. Aluminum replacement costs range from $6,000-$10,000 and offer exceptional durability and corrosion resistance.

Aluminum can survive damage that would destroy rubber or fiberglass. It won't puncture, tear, or develop leaks from debris. However, it's the heaviest roofing option, which affects fuel economy and cargo capacity. Aluminum conducts heat efficiently, which sounds good until you realize it means your RV heats up fast in summer and loses warmth quickly in winter. You'll need serious insulation to compensate for this.

Aluminum is best for: Vintage RV enthusiasts, those prioritizing absolute longevity over weight and thermal efficiency, and RVers who rarely face hail or heavy falling debris.

How Do RV Roof Replacement Costs Compare?

Let's talk about real numbers. Professional RV roof replacement typically costs around $300 per linear foot, meaning a 40-foot trailer runs approximately $12,000. But that's just an average.

For an average 250-square-foot RV roof, EPDM material costs $1,000-$2,000, TPO runs $1,250-$1,500, and fiberglass materials alone can cost $1,750-$3,750. Then add labor (typically $95-$150/hour), and most replacements take 8-40 hours depending on complexity.

Hidden costs hurt. Water damage repairs can add $600-$800 for structural repairs, and UV-damaged fixtures often crumble during removal, requiring replacement at $300+. Don't forget to account for disposal fees for the old roof.

DIY installation can slash total costs to $1,000-$4,000, but only if you're comfortable with the technical demands. Professional installations typically take 3-5 days and often include workmanship warranties that DIY jobs lack.

What Regular Maintenance Do Different RV Roof Types Require?

The maintenance procedures for each RV roof type vary. Follow the checklist below based on your RV roof type:

EPDM Rubber Roof:

• Clean your roof at least once a year, although cleaning it every 3-6 months helps keep it in better shape. Start by sweeping loose debris, then wash with mild detergent and a soft brush.
• Never use petroleum-based or citrus cleaners. They'll damage the membrane and void most warranties.
• Apply UV protectant after each cleaning to keep the rubber pliable and prevent premature aging.
• Check all seams, joints, and roof penetrations (including vents, skylights, and antennas) for failed sealant during every inspection.

TPO Rubber Roof:

• Follow the same cleaning schedule as EPDM (every 3-6 months) using mild detergent and gentle scrubbing.
• Pay extra attention to seam treatment. TPO requires more diligent seam care to prevent leaks from developing.
• Watch for the natural shedding that causes black streaks down the sides of your RV. Regular washing minimizes this issue.

Fiberglass Roof:

• Minimal attention required. Clean periodically to remove debris and check for cracks.
• Focus on preventing thermal stress in hot climates by ensuring adequate insulation underneath.
• Inspect for expansion-related issues if you frequently travel in extreme heat.

Aluminum Roof:

• Requires the least maintenance of all roof types. Clean occasionally to remove debris and prevent corrosion.
• Inspect for dents after hail or falling branches, as these are aluminum's main vulnerability.
• Check sealants around fixtures and seams annually.
