How Much Weight Can an RV Roof Hold?

RV roofs are crucial in keeping you, your passengers, and your gear safe and dry as you explore the great outdoors. But how strong are they? Is there an RV roof weight limit?

What many people want to know is whether it is okay to stand on or store items on an RV roof. If these questions have crossed your mind, you’ve come to the right place!

In this article, we’ll answer all those questions and provide helpful facts about RV roofs that everyone should know. Let’s get started!

How Much Weight Can an RV Roof Hold?

There isn’t much technical information on how much weight an RV roof can hold. Even manufacturers haven’t been very reliable in providing an RV roof weight limit.

Many folks in the industry and online believe that most RV roofs will safely hold upwards of 250 to 300 pounds. Of course, the genuine number depends on the RV construction and what materials the manufacturers used.

Rubber and fiberglass roofs are standard in most RV construction, and they are relatively strong. But if you don’t know a definite limit by the manufacturer, we recommend estimating on the low side to be safe.

Do Roofs Have Weight Limits?

Each camper will have an RV roof weight limit. Finding out that information from the manual or the manufacturer is another story. Believe it or not, it can be somewhat challenging to find the weight limit for an RV roof from the manufacturer.

Some RVs, particularly travel trailers and fifth wheels, have a sticker on the back of the RV or near its ladder that indicates a weight limit. This may even be on the ladder itself if you have one.

Is It OK to Walk on an RV Roof?

Generally, it’s okay to walk on an RV roof. However, there are a few things to consider. First, if your RV’s manufacturer gives you a weight limit in the manual, on the ladder, on a sticker at the back of the vehicle, or via a phone call or email, abide by it. Straight from the manufacturer is the most reliable information.

If you don’t have official guidance, we recommend sticking to the general direction that most RV roofs can tolerate 250 to 300 pounds. That doesn’t mean you should immediately scramble up there and start moving around.

Many RVs have a ladder. If yours has one, use it. If not, ensure that any ladder you use to get on the roof extends a good two feet above the roof line and that you have someone to keep it steady while you ascend.

When on the roof, stay near the edge at a safe distance, as this is the strongest portion of any roof because of the sidewall structure at the edges. Also, be wary as you move around the top. Be cautious around areas manufacturers have cut out, like near vents and air conditioning units. Also, tread lightly if you have water damage or soft spots on the roof.

You can lay a small section of plywood on the roof where you intend to be, to disperse your weight across a broader area. Using lengths of 2×4 boards can also help spread your weight.

Never go up on an RV roof when it is wet. Regardless of the roof type (rubber, fiberglass, or aluminum), it is too slippery and extremely hazardous to be on a damp RV roof.

What Happens If You Put Too Much Weight on a Roof Rack?

Putting too much weight on an RV roof rack can have severe consequences. It could damage your vehicle, the rooftop accessories, and even yourself if the frame or roof collapses.

The weight of all the items on a roof rack must never exceed the manufacturer’s limit, as this could cause structural damage or create excessive stress on the other RV components.

When placing items onto your roof rack, it is crucial to evenly distribute their weight and secure them with solid straps or ropes. Additionally, you should always inspect the rack for signs of damage before loading it with heavier items. Ensure that your tires are properly inflated to help reduce strain on the frame.

How Thick Is an RV Roof? 

The outer layer of an RV roof is usually fiberglass or a rubber coating. Some are aluminum. This outer layer is relatively thin and isn’t what provides the roof’s structural integrity. 

Most RV roofs have a skeleton of cross beams, joists, and other structural beams. They usually hold an underlayer of wood sheeting that’s plywood or OSB (oriented strand board). This wood sheeting is typically one-quarter or three-eighths of an inch thick.

This structure under the outer layer of the roof should provide a fair amount of support. However, if you are fortunate enough to get weight limit specifications from your manufacturer, follow them. If you don’t have such information, don’t exceed the widely-believed limit of 250 to 300 pounds.

How Often Do RV Roofs Need to Be Replaced? 

The frequency of replacing your RV roof will depend on the type of material it has, how the manufacturers installed it, and its level of care. Generally, you should inspect most RV roofs at least once a year to look for signs of wear and tear.

If your roof is fiberglass or aluminum, it can typically last 10-20 years before you need to replace it. However, you may need to replace rubber roofs more frequently due to their vulnerability to UV rays and other elements. You typically repair rubber roofs by painting on the rubber coat, which is easy for a handy DIYer to accomplish.

Keeping your RV roof in good shape will also determine how well it can handle the weight it should hold. The better you maintain your roof, the longer it can keep its weight limit.

Regardless of how well you maintain your RV roof, follow any manufacturer’s guidance about its limits and utilize reasonable safety procedures if you put yourself or any equipment on the roof.
