An outdoor kitchen hood is the difference between a covered patio that stays clean and one that ends up with smoke stains creeping across the ceiling within a season. BetterPatio carries outdoor range hoods from Summerset and Bull built specifically for exterior use, along with the vent panels every gas-fed island needs, so your outdoor kitchen vent hood actually does the job instead of just looking the part. Every order ships free, backed by our price match guarantee.
The term "outdoor grill hood" gets used two different ways, so it is worth clearing up before shopping. Sometimes it refers to the lid on a built-in grill itself, the stainless steel cover that closes over the cooking grates. This page is about the other meaning: a ventilation hood mounted above or behind the cooking area that pulls smoke, grease, and heat up and away from your patio, pergola, or covered structure.
An outdoor kitchen vent hood matters most the moment your grill sits under any kind of roof. In a fully open backyard, smoke simply drifts away on its own. Add a pergola, a covered patio, or a solid-roof structure, and that same smoke has nowhere to go. Over time it stains ceilings, peels paint, and causes stainless steel to pit and corrode as grease residue breaks down its protective layer.
Which mounting style you need depends on how your grill is installed.
BetterPatio stocks purpose-built outdoor range hoods rather than repurposed indoor units. Summerset vent hoods are available in 36, 42, 48, and 60-inch widths, all built from double-lined 304 stainless steel with rear and top venting and a mounting bracket included, so you can match the hood to your grill size rather than the other way around. For higher-output setups, a twin-fan option built on 304 stainless with commercial baffle filters delivers 1,250 CFM through two sealed motors with top or rear discharge, enough airflow for larger cooking surfaces.
Every gas-fed island also needs separate ventilation panels, not just an overhead hood. RCS stainless steel ventilation panels are required roughly every 4 feet along the island to release trapped gas, vent excess heat, and let condensation evaporate safely. If you are still comparing grill brands and outputs before choosing a hood, browse the full BBQ Grills collection to confirm your appliance's BTU rating first.
Two numbers matter most when picking a hood: CFM and physical width.
| Grill Output | Minimum Recommended CFM |
|---|---|
| Up to 60,000 BTU | 1,200 CFM (outdoor minimum) |
| 60,000 to 90,000 BTU | 1,200 to 1,500 CFM |
| 90,000+ BTU or multiple appliances | 1,500 CFM or higher |
Always confirm your grill's exact BTU rating against the hood manufacturer's specifications, since combined outputs on islands with a grill, side burner, and griddle add up quickly.
These are two separate safety features, and most outdoor kitchens need both. A vent hood clears smoke and grease from the air above the cooking surface. Vent panels are smaller cutouts built into the island cabinetry itself that release trapped gas so propane or natural gas cannot build up to dangerous levels inside an enclosed structure.
Placement depends on the gas type: propane is heavier than air, so panels should sit as low as possible, while natural gas is lighter than air, so panels should sit as high as possible, generally spaced every 4 to 6 feet. Always confirm exact spacing and clearance against your grill's manual and local building code, since covered or partially enclosed kitchens in some regions face stricter ventilation requirements than a fully open patio.
For a sense of where a vent hood fits into an overall project budget, BetterPatio's own cost data puts a vent hood at roughly $2,000 to $6,000 as part of a full outdoor kitchen build, depending on width, CFM, and finish.

BetterPatio sells vent hoods built specifically for outdoor exposure, not indoor range hoods with a weatherproof label slapped on. Every hood ships free and is backed by our price match guarantee, so you know exactly what CFM, width, and construction grade you are getting before it arrives.

If your grill is fully out in the open, you may be able to skip a vent hood, though it still protects nearby surfaces and your grill's components from smoke and grease. If your kitchen sits under a pergola, covered patio, or any solid roof structure, a vent hood is strongly recommended and may be required by local code in some areas.
A grill hood usually refers to the lid on the grill itself, the cover that closes over the cooking grates. A vent hood is a separate ventilation appliance mounted above or behind the cooking area that exhausts smoke, heat, and grease away from the space.
Aim for at least 1 CFM per 100 BTUs of your grill's maximum output, with a hard minimum of 1,200 CFM for any outdoor application. Larger islands with multiple appliances, such as a grill plus a side burner or griddle, should size up accordingly.
The hood should extend at least 3 inches beyond each side of your grill and be as deep as the cooking surface itself. When in doubt, size up, since a wider hood captures smoke more effectively, especially over multiple adjacent appliances.
Propane is heavier than air, so vent panels should sit as low as possible on the island. Natural gas is lighter than air, so panels should sit as high as possible. Both are typically spaced every 4 to 6 feet, though exact spacing should follow your grill's manual and local building code.
Summerset vent hoods are available in 36, 42, 48, and 60-inch widths in double-lined 304 stainless steel, and a twin-fan 1,250 CFM option is available for larger cooking setups. Match the hood width to your grill's dimensions, adding at least 3 inches of clearance on each side.
Yes. Stainless steel baffle filters should be cleaned regularly to remove grease buildup, which otherwise reduces airflow and forces the fan to work harder. The exterior should also be wiped down periodically with a stainless steel cleaner to prevent staining from smoke exposure.
