New house, new porch, old grill

Should the stars align in the next couple weeks with inspections, appraisals and whatever other elder gods we need to pray to in order to get this process finally over with, we should be moving into a new house in a few weeks. We have an awesome covered patio/porch in the back, which has me scratching my head as to how I want to set up my grill.

The porch itself is either plastic or a composite - I’m not quite sure of the difference. (I should probably go to Lowe’s this afternoon to look at the two side-by-side.) I’ve seen these used on the usual building shows (HGTV, DIY, etc.), and they seem to come highly recommended. It’s fully covered with a high-pitched roof (maybe 10’ at the edges, peak at maybe 16’?) It’s very large - maybe 20’x24’ at a conservative estimate. As such, I’d rather not have to set up the grill outside of it.

My grill is a Weber kettle that I take good care of, and has treated me extremely well the last few years. I’m a little nervous putting this on plastic/composite decking, but thought I’d get a protective grilling mat to put underneath. Is that sufficient protection for regular use? Any other concerns regarding ventilation on the porch?

I wouldn’t worry too much about the floor, a grill mat will be sufficient protection but grilling under a roof is going to be messy. All that sooty smoke is going up and getting trapped in the roof and leaving residue. Given the height I suspect you will be unhappy at having to clean it.

We have a composite deck and a generic charcoal grill. The only thing we were warned about was to keep it away from the vinyl railings, which is a DUH as far as I’m concerned. We’ve had no issues with the grill on the deck.

Make sure an old grill does not flake off pieces of metal as it can get in the food. Cast iron grills will do this over time. Just found out about it when a caterer examined my backyard grill.

I agree the covered porch may be present a smoke problem and possibly a carbon monoxide danger. I’m not sure how easily the fumes would vent vs collecting under that roof. A windy day should clear out any fumes.

I would store the grill on the porch. Move it a few feet away from the covered area before grilling. You could always put down some pavers to make a 4x4 ft area for the grill. After it cools it can be put away or left out for the summer.

I’m not an expert. You could set up a Co monitor on the porch and try grilling. See if it alarms.

Heres a garden web thread on grilling under a porch.

Someone mentions a ceiling fan. A good idea for comfort and it would help disperse fumes and smoke.

No, that won’t work. I have 3 steps I’d have to take it down, and it’s one of these - not all that portable.

There’s a low support beam that crosses the middle of the porch, but that’s definitely an option we’ll look into down the line.

CO is a ‘low’ gas, it doesn’t rise.

Is it open or are there any sides to the porch/patio? If so, screened or enclosed? If open, I don’t think CO will be an issue, & probably not if just screened sides.

It’s just slatted railings, so it’ll be fine. I think I’m just more concerned about soot. I keep my grill clean, but I’ll probably have to make an even stronger effort in that department.
