Your grill is built to withstand high heat, but constant exposure to rain, snow, sun, and humidity can significantly shorten its lifespan. Proper weather protection is essential for maintaining your grill's appearance, functionality, and longevity.
Why Weather Protection Matters
Even high-quality grills with weather-resistant materials will deteriorate faster without proper protection. Moisture causes rust, UV rays fade finishes, and temperature fluctuations can warp components. A good protection strategy can extend your grill's life by years.
Choosing the Right Grill Cover
Not all grill covers are created equal. The right cover should fit properly, use quality materials, and be designed for your climate and grill type.
Essential Cover Features
Waterproof Material
Look for heavy-duty polyester or vinyl with waterproof coating. Material should be at least 600D (denier) for durability. Cheaper covers may repel water initially but break down quickly under UV exposure.
UV Protection
UV-resistant fabric prevents fading and material breakdown from sun exposure. This is especially important in sunny climates where covers can deteriorate in just one season without UV protection.
Proper Ventilation
Mesh vents prevent moisture buildup and mold growth underneath the cover. Without ventilation, condensation can cause more damage than leaving the grill uncovered.
Secure Fastening
Drawstrings, buckles, or Velcro straps keep the cover in place during wind. A loose cover can blow off or flap in the wind, causing wear on both the cover and grill finish.
Getting the Right Fit
Measure your grill's width, depth, and height including the lid when open. The cover should extend at least 2-3 inches below the bottom of the grill. Too-tight covers are difficult to use and may tear; too-loose covers blow off easily.
Pro Tip: Custom vs. Universal Covers
Custom-fit covers designed for your specific grill model offer the best protection and easiest use. Universal covers work but may not fit as well around handles, side tables, and other features. If using a universal cover, size up rather than down.
Seasonal Protection Strategies
Spring & Summer
During active grilling season, you'll be covering and uncovering frequently. Focus on protecting from sudden rain showers and intense UV exposure.
- Always let grill cool completely before covering (at least 30 minutes)
- Cover immediately after cooling to prevent morning dew exposure
- Remove cover during use and store in dry location
- Check under cover weekly for moisture or debris
- Position grill to minimize direct afternoon sun exposure
Fall & Winter
Cold weather protection requires extra attention. Moisture from rain and snow combined with freezing temperatures can cause significant damage.
- Perform thorough cleaning before winter storage
- Apply protective coating to metal surfaces
- Remove propane tanks and store separately
- Stuff paper towels in burner tubes to prevent insects nesting
- Consider moving grill to covered area like garage or shed
- If leaving outside, elevate slightly to prevent ice contact
- Brush off heavy snow accumulation to prevent cover damage
Storage Location Matters
Where you keep your grill is just as important as how you cover it. The ideal location balances convenience with protection.
Covered Patio or Deck
Best option: Provides overhead protection from rain and snow while maintaining ventilation. Still use a cover for dust and side-blown precipitation. Ensure adequate clearance from house (10+ feet) for safety.
Open Yard or Patio
Most common: Requires high-quality cover and regular maintenance. Position away from sprinklers and drainage areas. Consider adding a grill gazebo or canopy for extra protection.
Garage or Shed
Winter storage: Excellent for off-season protection. Never use grill inside enclosed spaces. Ensure propane is disconnected and stored properly. Still use cover to prevent dust accumulation.
Additional Protection Methods
Protective Coatings
Beyond covers, protective coatings add an extra layer of defense against the elements.
- Stainless steel polish: Creates protective barrier and prevents water spots
- High-temp paint: Touch up scratches and chips to prevent rust spread
- Cooking oil: Light coating on cast iron grates prevents rust
- Silicone spray: Protects rubber gaskets and seals from cracking
Grill Mats and Pads
Place a protective mat under your grill to prevent rust stains on decks and patios. Mats also catch grease drips and make cleanup easier. Choose fire-resistant materials rated for outdoor use.
Cover Maintenance
Your grill cover needs care too. Proper maintenance extends cover life and ensures continued protection.
Regular Cover Care
- Brush off debris, leaves, and snow regularly
- Wash cover 2-3 times per season with mild soap and water
- Let cover dry completely before storing or re-covering grill
- Check for tears, worn spots, or deteriorating waterproofing
- Re-apply waterproofing spray annually if needed
- Store cover in dry location when not in use during active season
When to Replace Your Cover
Replace covers when you notice: significant fading or UV damage, tears or holes, loss of waterproofing that can't be restored, broken fasteners or straps, or mold/mildew that won't wash out. A quality cover should last 2-4 years with proper care.
Common Protection Mistakes
Covering a Hot Grill
Traps heat and moisture, can melt cover material, and creates fire hazard. Always wait 30+ minutes for complete cooling.
Leaving Propane Connected
Temperature fluctuations can affect pressure. Disconnect tanks during long-term storage and store in ventilated area.
Using Cheap Covers
Thin, poorly-made covers deteriorate quickly and provide inadequate protection. Invest in quality—it's cheaper than replacing grill components.
Ignoring Moisture Buildup
Check under cover regularly. Trapped moisture causes more damage than exposure. Ensure proper ventilation and dry grill before covering.
Weather Protection Checklist
Proper weather protection is one of the easiest and most cost-effective ways to extend your grill's lifespan. A quality cover and good protection habits will keep your grill looking great and performing well for many years, protecting your investment and ensuring you're always ready for your next cookout.
