If your horse has ever reared inside a trailer, you’ve probably had that heart-stopping moment: “Did they hit their head?”
That single moment is why Brad Heath, founder of Double D Trailers, created the SafeBump® Roof System; a seamless, flexible, composite roof that protects your horse where it matters most.
“I built the SafeBump® after hearing from a customer whose horse reared during loading and struck the roof. He was lucky. I wanted to make sure luck wasn’t the only thing standing between a horse and a cracked skull.” — Brad Heath, Founder, Double D Trailers
The SafeBump® roof system is a single-piece molded fiber composite horse trailer roof reinforced with Z-Frame tubing every 16 inches, designed to absorb impact and protect horses from head injuries during transport.
What Is the SafeBump® Roof System?
Material: Single-piece molded fiber composite
Support: Reinforced with Z-Frame tubing every 16" for rollover protection
Flexibility: Designed to flex slightly under impact to protect a rearing horse
Thickness: Approx. 1/4" (5–6x thicker than typical aluminum skin)
Temperature Control: Reflects heat, insulates cold — naturally stays cooler in summer
Maintenance-Free: No rivets, no seams, no resealing required
“The SafeBump® roof won’t crack, leak, or transfer heat like aluminum. It’s stronger, safer, and quieter, and our customers tell us they can feel the difference immediately.” — Brad Heath

Unlike traditional aluminum roofs made from thin sheets joined with seams and rivets, the SafeBump® roof is molded as a single continuous piece of fiber composite. With no seams or joints, the roof forms a smooth structural shell that spreads force across the surface rather than concentrating it in one spot.
Fiber composite also behaves differently than aluminum during impact. Aluminum is rigid and tends to transfer shock directly back to the horse. Composite materials are engineered to flex slightly under pressure, helping absorb and dissipate energy if a horse rears or strikes the roof.
Beneath the composite shell, Z-Frame steel tubing spaced every 16 inchesprovides strong structural support. This close spacing reinforces the trailer for rollover strength while still allowing the roof to flex where needed, creating a roof system designed specifically to help protect horses in real-world hauling situations.
How Does SafeBump® Protect Horses Better Than Standard Trailer Roofs?
SafeBump® protects horses by flexing under impact instead of transferring force directly to the head, reducing injury risk during rearing or rollover incidents.
Most trailers still use mill-finish aluminum roofs, which are:
Thin (often less than 1/16" thick)
Rigid and sharp, with rivets or seams that can cut a rearing horse
Uninsulated, trapping heat and cold inside the trailer
Prone to leaking, requiring regular resealing
In short, they’re not built with your horse’s safety or comfort in mind.
In a trailer accident or rollover, roof integrity can make the difference between survival and serious injury.
That’s why SafeBump® is reinforced every 16 inches with Z-Frame tubing, creating a roll cage effect that surrounds your horse with strength, not sheet metal.
We also include a rear header pad as standard to protect horses loading in confined spaces.
When a horse strikes a rigid aluminum roof, the metal has almost no give. The force of the impact is reflected straight back to the horse’s head, much like hitting a hard wall. Because aluminum skin is thin, the energy isn’t absorbed... it’s transferred.
The fiber composite SafeBump® roof responds differently. The material is engineered to flex slightly under sudden pressure, spreading the impact across the roof surface instead of concentrating it in one point. That controlled flex helps reduce the shock a horse experiences if it rears or loses balance during travel.
Underneath that composite shell, Z-Frame tubing spaced every 16 inches forms a structural cage, reinforcing the roof and surrounding the horse with strength designed to withstand real-world hauling stresses.
Which Double D Trailers Models Feature the SafeBump® Roof System?
SafeBump® is standard on every Double D horse trailer, including all bumper pull and gooseneck models.
You’ll find the SafeBump® Roof System on many popular designs, including:
2-Horse Straight Load Trailerssuch as the Bumper Sport and V-Sport models
SafeTack® Slant Load Trailers, including the SafeTack 2-Horse and 3-Horse models
Living Quarters Horse Trailers, designed for extended travel with integrated RV standard living spaces
Custom Gooseneck Trailersbuilt for larger hauling needs or multiple horses
Because the roof system is a core safety feature, it isn’t an optional upgrade. Every trailer is built with the same SafeBump® protection to help safeguard horses during loading, transport, and unexpected incidents on the road.
What Should You Look for When Evaluating Horse Trailer Roof Safety?
Unlike aluminum that acts like a frying pan under the sun, the composite material in SafeBump® naturally reduces heat absorption. That means:
Cooler trailer interiors on hot days
Less dehydration risk
Less stress on your horse during transport
No need for aftermarket insulation
This also reduces the energy needed for HVAC systems in living quarters trailers, a win for comfort and efficiency.
SafeBump® is built in a single molded piece, meaning:
No rivets to pop
No seams to split
No resealing needed
No water damage inside the trailer
It’s the most low-maintenance roof in the industry, and one of the most durable.
When evaluating a horse trailer roof, look beyond appearance and ask a few practical safety questions. Start with thickness.Many aluminum roofs are less than 1/16" thick, which offers little impact protection. A thicker structural roof material provides better resistance to dents, punctures, and sudden force.
Next, ask about structural reinforcement spacing. Roof bows or support tubing should be placed at consistent intervals. Closer spacing, such as every 16 inches, improves rollover strength and prevents the roof from oil-canning or flexing excessively under stress.
It’s also worth asking about insulation and heat transfer. Metal roofs can quickly absorb and radiate heat into the trailer, while composite materials help regulate temperature more naturally.
Finally, consider long-term maintenance. Roofs built with seams, rivets, and sealant typically require periodic resealing and leak checks. A seamless molded roof eliminates many of those maintenance concerns while reducing the risk of hidden water damage over time.
Standard in Every Double D Trailer
We don’t upsell safety. SafeBump® is a standard feature, included on every Double D trailer because you shouldn’t have to pay extra to protect your horse’s head.
