1. Water Leakage and Weatherproofing
Many Roll-N-Lock owners discover that their truck beds get wet during heavy rain, even when the cover is closed. Roll-N-Lock covers are water-resistant but not fully waterproof. In practice, water can seep through gaps where the cover meets the bed rails or tailgate.
Two leading causes of leakage are misalignment and overloading: if the cover isn’t perfectly aligned, “gaps for water to seep through” can open up.
Similarly, exceeding the cover’s weight capacity causes it to sag and hold rainwater, which then drips into the bed. A few simple steps can greatly reduce leaks:
Check and adjust alignment. Loosen the mounting clamps or screws and slide the cover laterally so it sits evenly on both side rails. A centered, level cover seals better against the bed.
Respect the weight limit. Avoid piling heavy loads on the closed cover. Roll-N-Lock recommends staying under the specified weight capacity, since “overloading…can lead to sagging” and ponding. If you frequently haul heavy cargo, consider upgrading to a high-capacity model.
Inspect seals and drains. Ensure the rubber weatherstrip at the tailgate lip is intact and the built-in drain tubes (on many models) are clear. Clogged drains cause standing water; clear any debris with compressed air or a pipe cleaner. You can also add an aftermarket tailgate seal strip to block moisture at the tailgate hinge.
Regular maintenance. Clean the cover and rails with mild soapy water and a soft cloth, then lubricate sliding parts with a silicone spray. Keeping the cover and tracks clean prevents leaks caused by dirt buildup. After maintenance, test with a garden hose or in a car wash to spot any remaining drips.
With proper alignment and routine care, most Roll-N-Lock covers will keep water out. Remember: even the best retractable cover will let a tiny bit of moisture in around the tailgate under heavy storms, but these fixes will minimize it.

2. Difficult Closing/Opening and Tailgate Fit
A common headache is when the cover won’t latch or the tailgate won’t close properly. Often this is due to sagging rails or improper installation.
For example, if the cover sits lower at the tailgate than the side rails, the tailgate can’t seal, or it closes unevenly. Likewise, if the tailgate is locked up by the cover’s latch, it indicates a misalignment. To address this:
Realign the cover assembly. With the cover unlocked, raise and lower the cover slowly. Look for binding or one side dropping. Then loosen the bed clamps and shift the cover forward/backward or side-to-side until it rolls down smoothly without lifting on one side. Re-tighten and re-test. Realignment often cures the closure problem.
Verify tailgate clearance. Make sure the cover is compatible with your truck (no incorrect model installed). When the cover is closed, the tailgate should seat flush against it. Some owners find that closing the tailgate first, then rolling the cover back down, gives a better seal.
Check bumper blocks and latches. On some Roll-N-Lock models, rubber bumper blocks at the tailgate latch area help center the tailgate on the cover. If these blocks are worn or missing, replace them. Also examine the internal latch – debris or damage here can prevent a full lock.
By carefully aligning the cover and ensuring the tailgate mates correctly, you can restore smooth opening/closing. If the cover still interferes, remove the cover and reinstall it step-by-step per the manufacturer’s guide.

3. Sagging and Overload Issues
If your Roll-N-Lock cover bowls in the middle or droops noticeably near the tailgate, weight or alignment is usually to blame. Roll-N-Lock covers have a rated load capacity; exceeding it – even by a few hundred pounds – causes the cover to buckle under weight. Similarly, if one side rail was mounted lower, the cover may flex down on that side. To solve sagging:
Reduce the load. Make sure no more than the specified weight (check your model’s manual). Remove heavy items from the bed or consider a heavy-duty version if you routinely carry substantial cargo.
Readjust alignment. Loosen the clamps on both sides, lift the middle of the cover by hand (or use a jack under the center), and level the rails before tightening. When realigned, the cover should be uniformly supported.
Upgrade if needed. In extreme cases, even correct installation may not hold an excessive load. Roll-N-Lock makes higher-duty covers (for example, an electric E-Series offers a stronger spring tension). If your workload demands it, a reinforced or heavier-duty cover may be worth the investment.
By keeping loads within spec and resetting the cover’s pitch, you can eliminate most sagging. A level cover both looks better and seals out the elements more effectively.

4. Jammed Locks and Latches
A stuck or jammed lock is one of the most frequent maintenance issues. Dirt, debris, or corrosion can lodge in the key cylinder or latch over time, making it hard to turn the key or engage the lock. Roll-N-Lock covers also have a patented latch at the tailgate; if that latch jams, the cover won’t release. The good news is that a little cleaning and lubrication usually fixes it:
- Clean the lock cylinder. Use compressed air to blow out loose dust from the keyway. Then insert a small brush (a dry toothbrush works well) and scrub gently to remove any remaining grime. Avoid using WD‑40 in the cylinder as it can gum up; instead, use a pencil’s eraser to clean the pins if you have one.
- Lubricate the mechanism. Apply a few drops of dry graphite lubricant or a silicone-based spray specifically made for locks. Insert and rotate the key several times to work it in. This often restores smooth operation.
- Inspect the tailgate latch. On the underside of the tailgate, the latch that catches the cover can also jam if dirty. Clean and grease this pivot with lithium grease or Boeshield T-9 (a film lubricant). Test that the latch spring snaps freely.
- Replace worn components. If cleaning doesn’t help, the lock cylinder may be bent or the internal latch parts could be worn. In that case, install a new lock kit. Roll-N-Lock replacement locks are available (ensure you get the right model), and installation is straightforward.
Key Takeaway: Regularly clean and grease the key lock and tailgate latch. A sticky lock is usually cured by debris removal and lubrication. Keep a small container of lock lubricant on hand, especially after winter or dusty drives.
5. Retractable Track and Mechanism Troubles
If the cover sticks partway when retracting or won’t fully roll up, the tracks or rollers may need attention. Even fine grit in the rails can halt the heavy cover. Follow these steps:
- Clear the track. Carefully inspect both side rails from front to tailgate. Remove any rocks, mud, or twigs lodged in the channels. Clean the tracks with a damp cloth, then dry thoroughly.
- Lubricate sliding parts. Apply a silicone-based lubricant (never oil-based, which attracts dirt) along the entire length of each rail. Work the cover back and forth several times to spread the lube. This reduces friction and helps the cover glide.
- Check for binding. Slowly cycle the cover up and down; note any high points where it takes extra effort. If the cover remains firm at the same spot, there may be a bent rail or misadjusted bracket. Loosen the clamps and make fine adjustments to remove the bind, then retighten.
- Verify motor/electronics (E-Series). On electric models, ensure the battery is charged and connections are solid. If the motor hums but stalls, an obstruction is likely; if it doesn’t move at all, consult a professional, as the motor or switch may need repair.
By keeping the tracks clean and well-lubricated, most retraction problems disappear. Actionable
Tip: Make track cleaning part of your vehicle wash routine, especially after off-road use. A clean track prevents the cover from “freezing” in place.
6. Cold Weather and Freezing Concerns
In winter, some owners find that a Roll-N-Lock cover freezes shut or its latch mechanism locks up. Moisture on metal parts or inside the lock can freeze solid, preventing operation. To avoid winter woes:
- Keep it dry. After exposure to rain or snow, lift the cover and clear any water in the tailgate area. Wipe down rails and lock areas if possible.
- Apply anti-freeze lubricant. Use a silicone or PTFE (Teflon) spray on the lock cylinder and latch pivots before a freeze. These products repel moisture. One forum-recommended product is Boeshield T-9, which leaves a dry wax-like film. Even a light coating of automotive wax on the rails can keep ice from bonding.
- Park smart. If you know temperatures will drop below freezing after a wash, leave the tailgate unlocked when washing – this prevents ice binding the latch. Also, avoid parking with the cover down in the snow if you plan to open the tailgate later.
By preventing water intrusion and protecting the moving parts, you can reduce winter freeze-ups. Remember that Roll-N-Lock’s powerful torsion spring will remain locked with the tailgate if frozen – so be patient and warm things up if it does freeze.
