Spring is the perfect time to give your restroom trailer a thorough check-up before the busy season begins. One area that often gets overlooked? The roof. After months of exposure to winter weather—especially if your trailer was stored outside—it's important to get up top and inspect your seals, caulking, and A/C unit to prevent leaks and other costly issues. In this blog post, we'll walk you through exactly what to look for and how to fix common problems.

Important: Always use caution when accessing the roof of your trailer. Never climb up alone, and only proceed if you're confident doing so safely. If you're unsure, hire a professional.

Step 1: Inspect All Roof Seals and Seams

The first thing you’ll want to do is check the caulking around all seams, edges, and vents:

• Look for cracks, peeling, or areas where the caulk is pulling away from the surface.
• Pay close attention to the vent stack caulking, which is a common spot for deterioration.

If the caulk is damaged:

1. Remove the old caulk completely.
2. Clean the surface using denatured alcohol.
3. Apply a quality hybrid sealant (avoid silicone-only products, which don’t last as long outdoors).

Step 2: Examine the Corner Tape and Seams

Over time, corner tape and seam tape can break down due to exposure to UV rays, snow, and freezing temperatures.

Here’s what to do:

• Check all taped seams for cracks, bubbles, or lifting edges.
• If the tape is beginning to deteriorate:
  • Clean the area with denatured alcohol.
  • Apply hybrid sealant to reinforce and reseal the seam.

Step 3: Inspect the A/C Unit

Your roof-mounted air conditioning unit also needs attention before it kicks into high gear for spring and summer.

Check the following:

• The shroud (plastic cover) – Make sure it isn’t cracked and is still securely attached.
• The mounting bolts – Confirm all bolts are present and tightened.
• The vent openings – Remove any leaves, twigs, or debris that may have built up inside during storage.

Step 4: Perform General Roof Cleaning

While you’re up there:

• Sweep off leaves, dirt, and other debris.
• Check the overall condition of the roof’s surface for any soft spots, discoloration, or damage.

Final Tip: Make Roof Checks a Regular Habit

Don’t wait until a leak shows up to check your roof. By making this a part of your spring maintenance checklist, you’ll catch small issues before they become big problems—and you’ll extend the life of your restroom trailer in the process.

Keep Your Trailer Leak-Free and Ready to Go

Taking just 20–30 minutes to inspect and reseal your restroom trailer's roof each spring can prevent costly damage. From the caulking and corner tape to your A/C unit, these small checks go a long way in ensuring a smooth and worry-free rental season.
