As a homeowner, you undoubtedly take pride in the beauty of your deck. You try your hardest to protect it and keep it looking its best. If you regularly grill on your deck, you know it can be a bit of a messy undertaking. Grease will splatter, food will fall, and if you need to move your grill, it can leave unsightly scuff marks on the surface of your deck. However, a grill mat might help to alleviate some of these problems, allowing you to keep your deck looking good, while still enjoying a good BBQ!

Why Should I Put a Mat Under My Grill on a Deck?

Placing a mat under your grill is a good idea for casual grillers and professional pitmasters alike for a number of reasons. First, a mat will protect your deck from any grease or fallen food. It can also help keep your deck safe from getting scratched by the wheels or feet of your grill. From a safety perspective, a grill mat can also aid you in avoiding a fire caused by an errant spark or ember.

A grill mat can help keep your grill stable in windy conditions, and it creates a level surface for added stability. A well-made grill mat is also easy to clean. Simply hose it down to remove grease or debris.

What to Consider When Purchasing a Grill Mat for Your Deck

If you’re thinking about purchasing an under-grill mat, there are a few different types to consider. To get a better idea of which grill mat is right for you, think first about what material your deck is made from. 

If you have a composite deck or concrete patio, you’ll want to stay away from rubber-backed mats, as they can cause discoloration that isn’t easy to fix. A grill mat can also block UV rays from the sun, meaning that the area beneath the mat may not fade at the same rate as the area around it. 

Another consideration is the type of grill you have. A gas grill, for example, is more prone to drips and splatters, so you’ll need to look for a mat that can handle grease and oil. On the other hand, if you have a charcoal or wood grill, look for a heatproof mat that will help protect against burning hot embers making contact with the surface of your deck.

Of course, it’s also important to consider the side and dimensions of your grill. Don’t just buy any old mat, and find out too late that your grill is bigger than the mat you bought!

With those considerations in mind, here are some of our top picks for the best grill mats – tailored to specific scenarios and needs!
