How to choose a grill covers
Updated June 2026Independently researchedNo paid placement.
To choose a waterproof grill cover, focus on a material like heavy-duty polyester with a waterproof coating or vinyl, measure your grill’s full dimensions including handles and shelves, and look for features such as vented panels to prevent condensation and secure straps for wind resistance.
What material should a waterproof grill cover be made of?
The most common and effective material for a waterproof grill cover is heavy-duty polyester with a PVC or polyurethane coating. This combination repels rain well, resists tearing, and handles sun exposure better than cheaper polyethylene tarps. Vinyl covers are also very waterproof but can be heavier and less breathable, which may lead to mold if moisture gets trapped underneath. Canvas covers are an option but require periodic waxing to stay waterproof and are generally heavier. Avoid thin, non-coated polyester or generic nylon covers labeled only as “water-resistant”. they will soak through after a few hours of steady rain. Look for mentions of UV inhibitors, taped or sealed seams, and a thickness of at least 300 denier for polyester, though exact numbers vary by brand.
How do I make sure I get the right size cover?
Measure your grill from front to back (depth), side to side (width), and from the top of the lid to the ground (height). Be sure to include any protruding handles, side shelves, and a gas tank if mounted externally. A cover that is too small will tear at the seams, and one that is too large will pool water on top, leading to sagging and mildew. Most manufacturers provide a size chart based on these dimensions. For example, a typical three-burner gas grill often needs a cover around the size labeled “medium” or “large,” but always compare the listed measurements to your own. If you have a charcoal kettle grill, measure the diameter of the bowl and the total height including the lid and legs.
What features actually matter for weather protection?
Key features go beyond just waterproof fabric. Look for vented panels or air vents near the top of the cover to let rising heat and moisture escape. Without vents, condensation can build up inside and cause rust or mold. A drawstring hem with a toggle or a set of adjustable buckled straps around the base helps keep the cover in place during wind. Reinforced handles on the top can make removal easier, but ensure they are sealed and not weak points. Double-stitched seams and fabric loops that attach to the grill legs provide extra security. Some covers include a zippered vent that can be closed in heavy rain, a nice touch, but check user feedback for zipper durability.
Should I get a different cover for a charcoal vs. gas grill?
Gas and charcoal grills differ in shape, size, and heat management, but many covers work for both if sized correctly. Gas grills often have a rectangular footprint with side shelves and a hood, so a rectangular cover with extra depth for shelves is ideal. Charcoal grills range from round kettles to large offset smokers, so look for a cover that matches that specific shape. Heat tolerance matters less for the cover itself because you should always let a grill cool completely before covering it in a waterproof cover. That said, covers made for charcoal grills sometimes have a shorter profile to fit the bowl. The primary difference is size and shape, not material or waterproofing, so measure and pick a cover designed for your grill type.
How do I care for a grill cover to make it last?
Regular cleaning extends the life of any grill cover. Occasionally hose off dirt and bird droppings, and wash with a mild soap solution for stubborn grime. Let it dry completely before putting it back on the grill, storing a wet cover can promote mildew and reduce waterproof coatings. In harsh winter climates, some users bring covers indoors to prevent cracking and UV damage during storage. If you leave it on, remove heavy snow buildup to avoid stressing the fabric. Inspect seams and straps seasonally; a small tape patch or seam sealer can fix minor pinholes before they become leaks. When the coating starts flaking or the fabric tears easily, it is time to replace the cover.
What about UV protection and fading?
Sunlight degrades fabric over time, so a cover with UV inhibitors or a UV-resistant coating will last longer. Darker colors absorb more UV but also more heat, which can contribute to interior condensation, though vents help. Lighter colors reflect sunlight better but show dirt more easily. Most quality covers add UV stabilizers to the polyester or vinyl. The trade-off is that UV protection eventually wears off after several seasons of full sun. If your grill sits in direct sunlight all day, expect to replace the cover every 2 to 4 years, even with good care. Rotating the cover occasionally can help distribute wear evenly.
Frequently asked questions
Are all grill covers truly waterproof?
No, many are water-resistant, not waterproof. Genuinely waterproof covers use a coated fabric (PVC or PU) and sealed or taped seams. Check the product description carefully; if it says “water-repellent” or “weather-resistant,” it may not withstand heavy rain for long.
How do I measure my grill for a cover accurately?
Measure the widest width, deepest depth, and tallest height including handles, side shelves (if they fold down or are removable), and a propane tank. Write these numbers down and compare them to the cover’s listed interior dimensions, not the grill size it claims to fit.
Can a grill cover withstand high winds?
It helps if the cover has a drawstring or buckled straps to cinch it around the base, or fabric loops that attach to the grill legs. Without these, wind can lift a loose cover and tear it or blow it away entirely.
Do I need a heavy-duty cover for year-round outdoor use?
If your grill stays outside through all seasons, yes, a heavier fabric (300 denier or more) with UV protection stands up better to winter storms and summer sun. Lighter covers work fine for occasional use or in mild climates.
How often should I replace a grill cover?
With good care, a quality waterproof cover lasts 2 to 4 years. Harsh sun, frequent rain, and strong winds shorten that lifespan. Replace it when you see cracks in the coating, persistent leaks, or torn seams.
Should I cover my grill when it is still warm?
No, always let the grill cool completely before putting on a waterproof cover. Covering a warm grill traps steam and moisture inside, which accelerates rust and can damage painted surfaces.
