Why Roof Top Tents Especially Need Seasoning? A Professional Pre-Treatment Guide

The Unique Challenges of Roof Top Tents

Unlike ground tents, roof top tents are permanently mounted on vehicles and constantly exposed to extreme conditions:

• High Winds: Continuous stress on seams during high-speed driving or windy weather.

• Temperature Fluctuations: Fabric expands under sun exposure and contracts at night, leading to potential micro-leaks.

• Frequent Vibrations: Bumpy roads can loosen untreated stitching over time.

If leaks occur, the mattress, bedding, and gear inside can get soaked, making it extremely difficult to dry while on the road. This is why seasoning (pre-treatment) is a crucial step for roof top tents.

Four Key Benefits of Seasoning

1. Enhanced Waterproofing
   Cotton-polyester blend fabric shrinks when first wet, naturally sealing tiny needle holes in the seams.

2. Reduced Mold Risk
   Thorough drying prevents moisture buildup, inhibiting mold and odors.

3. Improved Comfort
   Seasoned fabric stays warmer in rain and resists wind drafts.

4. Extended Durability
   Minimizes fabric wear, seam tears, and premature aging caused by water seepage.

Which Roof Top Tents Need Seasoning?

Not all tents require seasoning, but those with the following features strongly benefit from it:

• Material: Made of 280gsm or 320gsm cotton-polyester canvas (common in mid-to-high-end tents).

• Construction: Features exposed double-stitched seams without heat-sealed or taped edges.

• Functionality: Marketed as "breathable and waterproof" canvas tents.

Note: Even if a manufacturer claims the tent is "pre-seasoned," performing an additional treatment before first use is advisable, especially for camping in humid or rainy regions.

Step-by-Step Seasoning Guide

What You’ll Need

• Garden hose or spray nozzle

• 2 consecutive sunny days (for thorough drying)

• A well-ventilated, open space

• A ladder or low支架 (for easy access)

Detailed Steps

1. Fully Unfold the Tent

• Open the tent completely on the roof rack or stand, ensuring all zippers, vents, and windows are in their camping-ready positions.

2. Soak the Tent Thoroughly

• Use a gentle spray to wet the entire surface, paying extra attention to:

  • Stitched seams (especially exposed double stitching)

  • Door and window edges

  • Corners and joint areas

• Avoid high-pressure washers, which can damage waterproof coatings.

3. Let It Dry Naturally in the Sun

• Sun drying is critical for fiber shrinkage and seam sealing.

• Never fold or pack the tent while damp, as this promotes mold growth.

4. Repeat 2–3 Times

• Minor leaks may persist after the first round but should disappear with repetition.

• Typically, 2–3 cycles ensure optimal waterproofing.

Seasoning FAQ

Q: Can I use waterproof spray instead of seasoning?
A: Not recommended. Sprays only coat the surface, whereas soaking and drying structurally seal fabric fibers.

Q: Does seasoning need to be done yearly?
A: Usually once is enough. If leaks reappear after years of use, a repeat treatment may help.

Q: What if I camp in the rain before seasoning?
A: Rain acts as a "passive seasoning," but ensure the tent dries completely afterward to prevent mold.

Q: Does seasoning reduce breathability?
A: No. Canvas remains breathable while becoming more waterproof—a key advantage over synthetic materials.

User Testimonials: Why Seasoning Matters

"I seasoned my SMARCAMP tent before a trip. On the second night, it poured, but not a drop leaked inside. My friend’s untreated tent flooded, forcing him to sleep in the car."
— Jason L., Colorado, USA

"I skipped seasoning initially, and water seeped through every window seam. After redoing it properly, my tent stayed bone-dry even in heavy storms."
— Amanda P., Oregon, USA

Final Tip: Don’t Let Leaks Ruin Your Adventure

A roof top tent is your "mobile bedroom" in the wild, and seasoning ensures its reliability. Just 1–2 days of effort can secure 3–5 years of worry-free camping.
