How Do I Know My RV Roof is Damaged?
While some indications that your RV roof is damaged or leaky are obvious, such as water streaming in during a rainstorm, other signs of damage may not be as readily apparent.
Understanding what to look for can make your inspections more efficient and bring your attention to problems when they're small enough to be a fairly fast and inexpensive repair.
Corrosion
If metal is part of the roofing structure or material, water damage can quickly lead to corrosion. You may notice that the metal is discolored, rusty or flaking off.
Water damage
Water damage can take many forms. The interior of the RV may smell like wet newspapers, which indicates mildew, or you may notice mold inside. Black mold can be especially insidious and cause health issues for people and pets. If you spot black mold, you may need a professional remediation service.
Other signs of water damage are peeling or wrinkled wallpaper, discolored streaks down the walls, or damp patches on the fabric in the interior.
Uneven temperatures or drafts
If there's a noticeable cold spot or if you feel a draft, that indicates a hole or crack that needs to be fixed. Or, if you notice that you have to run the RV heater or air conditioner more often than usual to achieve the same temperature you like, there could be hidden drafts.
Sometimes, you may need a professional to inspect the vehicle, finding leaks or drafts thoroughly you may overlook.
What to Consider Before Replacing an RV Roof?
Before deciding to replace your old RV roof, consider all possible repair options first. Many common roofing issues, such as minor leaks, cracks, and aging materials, can be effectively addressed with high-quality sealants, preventing a full replacement.
Start by assessing the age of your vehicle. If your RV is over ten years old, you may start noticing wear and tear, but this doesn’t always mean replacement is necessary. Repairing damaged areas with a durable sealant can extend your roof’s lifespan and save you significant costs.
Older RV roofs tend to become brittle, crack, and leak more easily, leading to costly repairs. However, before committing to a complete replacement, check the condition of the existing roof material. If the structural integrity is still sound, sealing and reinforcing it with Liquid Rubber products may be the smarter, more cost-effective solution.
What is the Cost to Replace an RV Roof?
Once you know your RV's roof type, you should consider the cost of replacing it. The cost will vary depending on the size of the RV, the type of roof, and the materials used.
Generally speaking, a small RV roof replacement can cost between $2500 and $5,000, while a larger RV roof replacement can cost between $5,000 and $10,000.
In addition to the cost of the materials, labor costs should also be considered. If you choose to hire a professional for the job, then you can expect to pay anywhere from $1000 to $2,500 for labor, depending on the size of the RV, the type of roof and the complexity of the job.
If you choose to do the job yourself, you can expect to pay only for the materials and the investment of your DIY sweat equity.
DIY RV Roof Repair vs Professional Replacement
When fixing your RV roof, you have two main options: DIY repairs using Liquid Rubber or hiring professionals for a full replacement.
Taking the DIY route with Liquid Rubber RV Roof Coating can save you significant labor costs while providing a durable, waterproof seal that extends the life of your roof. This option is ideal for RV owners who are comfortable with hands-on repairs, as it’s a straightforward process with the right tools and guidance.
On the other hand, hiring professionals for a full roof replacement ensures the job is done correctly and safely, but it comes at a much higher cost. Professional installation is best suited for cases where the roof is severely damaged beyond repair or requires structural fixes.
Here’s a comparison table illustrating the costs of DIY RV roof repairs using Liquid Rubber versus hiring professionals for an RV roof replacement:

Why Do I Need to Recoat My RV Roof?
Recreational vehicles, or RVs, are notorious for leaks and other hazards. Plus, these vehicles may often be sitting unused for weeks or even months at a time, so you may not realize that your RV leaks until it's a big one that damages the structure's interior.
If you own an RV, you need to know several things about inspecting the roof and ensuring that it protects you, your family, and your belongings.
Here's a cost comparison table focusing on different types of RV roof damages, the financial impact of addressing them proactively versus reactively, and potential additional insights:
Cost Category | Repair After Damage | Proactive Maintenance |

As this comparison demonstrates, proactive maintenance of your RV roof is significantly more cost-effective than dealing with the aftermath of damage.
By investing in regular inspections and applying Liquid Rubber RV Roof Coating, you can prevent costly repairs, extend the lifespan of your roof, and ensure a comfortable and safe RV experience for years to come.
Types of RV Roofs
There are several different types of RV roof replacement. The most common type is a rubber roof.
Roof Type | Durability | Weight | Cost | Maintenance | Special Tools Required |
Rubber | High | Lightweight | Inexpensive | Low | No |
Metal | Very High | Lightweight | Expensive | Low | Yes |
Fiberglass | High | Heavy | Moderate | Low | Yes |
Acrylic | Moderate | Very Light | Inexpensive | Low | No |
Each roof type has advantages and drawbacks, so the best choice depends on your specific needs. If cost and ease of installation are top priorities, rubber or acrylic roofs might be ideal.
Metal or fiberglass roofs offer long-lasting performance for those seeking durability and minimal maintenance. Consider weight, cost, and upkeep to find the perfect roofing solution for your RV.
When Should I Apply RV Roof Coating?

The best time to apply rubber RV roof coating to your vehicle is in the early morning or evening when it's cooler, and the roof isn't exposed to full sun. Check your weather forecast for a period of time when it's dry and not very humid, as the coating can take up to 48 hours to set and cure.
When you use Liquid Rubber Sealant products, follow the application instructions carefully. The instructions will indicate how long the product takes to cure so you can schedule the application around your local weather patterns.
Liquid Rubber RV Roof Coating stands out for its easy application process. Its liquid form ensures complete coverage of the entire roof. Simply pour the material on the roof, spread it out, and let it dry for a new, robust, long-lasting roof.
How Often Do I Need To Seal My RV Roof?
You should inspect and maintain your RV roof and the rest of the vehicle every six months to catch small problems before they become large, expensive ones. However, you don't need to recoat the seal on your RV roof every six months.
In fact, recoating the seal every two to four years is ideal, depending on the weather and environment you drive through regularly. Certain climates can cause more wear and tear on the roof than others. Always inspect the roof for damage after a large storm or heavy snow.
With Liquid Rubber RV Roof Coating, maintenance becomes a breeze. The first 10 years after application, the roof requires minimal attention besides regular cleaning and inspection. This product can withstand extreme temperatures and protect against UV rays, ozone, and other elements.
What kind of sealant products should I use on my RV?
Liquid Rubber created a line of products specifically for RV roof coating use. Our online catalog has an extensive selection, so you can find one that suits your needs. The best all-around product is the RV Coating and the Liquid Rubber EPDM Primer, which provides the best protection against the elements.
We've even created an easy-to-follow video that shows you how to apply liquid rubber products properly and provides tips for the best results. After all, you'll only get maximum effectiveness when you use our products properly.
Benefits of Recoating Your RV Roof

There are many reasons to regularly recoat your RV roof, sealing it against water damage, sun, wind, and wear and tear.
Extends the life of the roof
Like any motor vehicle, RV roofs are built to withstand tough weather, from snow to hail to a deluge. However, the roof material can still wear out over time. Coating the roof with sealant regularly ensures that you can extend the roof's life and, often, the vehicle's life in general. RV rubber roof coating is easy for even a new DIY handyman to apply.
Prevents leaks and drafts
Rubber RV coating can also help protect your RV against leaks and drafts. Small cracks in the roof or separation between pieces allow air and water into the interior, which can be uncomfortable.
Plus, if there are drafts in the RV, your heating and cooling system has to work much harder to maintain a comfortable temperature, which, in turn, can cause it to wear out more quickly.
More comfortable interior
Many prefer RVs over tents or pop-up campers because they're warm and dry. Unfortunately, when your roof leaks or you feel drafts all night, you're not getting the most out of your motorhome.
Reduce repair bills
Everyone knows that the earlier you catch a problem, the cheaper it is to fix, and that's very true of RV roofs. If you find a small leak or drafty place, you can seal over it to protect it. However, if you aren't inspecting your roof regularly, you'll miss the minor problems. If a leak goes unchecked, it can grow and may cause water damage to the vehicle.

Frequently Asked Questions
How Do I Reseal My RV Roof Myself?
Resealing your RV roof is a manageable DIY project if you take it step-by-step. Here's a simplified overview:
- Inspection and Preparation: Inspect your roof for cracks, old sealant, and damage. Clean the entire roof surface using an RV roof cleaner and a scrub brush. Let it dry completely.
- Remove Old Sealant: Carefully remove any failing or cracked sealant around vents, skylights, and seams using a plastic scraper or specialized sealant removal tool. Be careful not to damage the roofing material.
- Apply New Sealant: Using a self-leveling sealant (specifically designed for RV roofs), apply a generous bead along all seams, around vents, skylights, and any other roof penetrations. Allow the sealant to self-level according to the manufacturer's instructions.
- Address Cracks/Damage (If Applicable): If you have cracks or damage, consider using RV roof repair tape or a liquid rubber coating, following the product instructions carefully.
- Inspect and Cure: Once the sealant has cured (check product instructions for curing time), inspect the entire roof to ensure all areas are properly sealed.
Important: Always consult the specific instructions for your sealant and repair products. Safety first!
Can I Use Regular Silicone Caulk on My RV Roof?
While regular silicone caulk might seem convenient, it's generally not recommended for RV roofs. Regular silicone doesn't adhere as well to RV roof materials, can dry out and crack more quickly under constant exposure to sun and weather, and isn't usually self-leveling.
Invest in a sealant specifically designed for RV roofs for a more durable and reliable seal.
What Happens If I Don't Maintain My RV Roof?
Neglecting your RV roof can lead to serious and costly problems. Water leaks are the primary concern. Even small leaks can cause:
- Structural damage: Rotting wood, weakening of the roof structure, and damage to walls and ceilings.
- Mold and mildew growth: This creates unhealthy living conditions and damages the RV's interior.
- Insulation damage: Reducing the effectiveness of your RV's insulation.
- Costly repairs: Addressing water damage is significantly more expensive than preventative maintenance like regular inspections and resealing.
Regular maintenance of your RV roof is essential to protect your investment and ensure years of worry-free travel.
How do I know if my RV roof is EPDM or TPO?
To determine whether your RV roof is made of EPDM or TPO, follow these steps:
- Locate the Overhead Roof Vent: Find a roof vent on your RV.
- Remove the Vent Trim Ring: Unscrew and take off the trim ring to expose a section of the roof material.
- Inspect the Material: If possible, remove a staple from the roofing material and examine both sides:
If one side is white or dove gray with a black backing, it is likely EPDM. If both sides are the same color (often white) and may have a smooth or fleece backing, it is likely TPO.
What is the difference between RV roof sealant and coating?
The primary difference between RV roof sealant and coating is their purpose and application.
- Sealant: This is typically used to fill gaps, seams, and cracks in the roofing material. It provides a waterproof barrier to prevent leaks and is often applied in specific areas, such as around vents, seams, and other penetrations. Sealants are usually thicker and designed for specific repairs.
- Coating: This is a protective layer that covers the entire roof surface. Coatings are generally applied to enhance UV resistance, reflectivity, and overall roof durability. They can help extend the life of the roofing material by providing an additional barrier against weather elements.
Both products are essential for maintaining an RV roof but serve distinct functions, ensuring its longevity and performance.
