Venting the heat out of the top of my arched exposed breezeway?

Here is something I didn't think through.

We added a nice solid covered breezeway linking our shop to our main garage and house. Wife loves it. Really a great addition.

350 days of the year, it's perfect.

But when it gets above say 85°F the ridge vents do little and the heat builds like a hellish inferno from head height up to 16+ feet at the ridge. The sun just blazing on the roof. I could cut some vent holes....I really don't want to go there.......I guess.

Open to ideas

I'm confused. Is it fully the framed with walls? It's not insulated correct?
 
Looking UP, this was 2022 before I stained it (out is NORTH in this picture)

Sorry, breezeway is open on north and south ends. A structural cover linking what WERE separate insulated buildings.

Ahh. Gotcha. I would just live with it. If there isn't a lot of air movement across the breezeway in general I don't think you're going to experience a significant reduction in temps.

You need a Gazebo Mounted Fan, my dad put 1 of those Metal Gazebos on the Deck and even though there is an opening up top it gets Hot here. The Fan will blow out the heat and make it more pleasant. We can sit out in 90-degree weather with the sun blasting down and the fan blows all of the heat out or makes it more pleasant.

You need Air Movement!

I know you dont want to cut a hole, don't blame you ... but solar roof vent perhaps?
Gosh, hard to imagine heat with the way that is open.

I'm heat sensitive!!

Only a problem when the temp is pushing over 85°F, sun beating on the ~SW roof portion and air absolutely still. As soon as the earth rotates for trees to the west to block, then area temp drops off.

I think I should have used taller ridge vent. I didn't anticipate the heat build up.

Yep, we live in different areas. Just approaching 10 AM. Temperature is up to 88° and I am going to finish up some landscaping dig up a magnolia plant a small palm tree and then run to the nursery and pick another one up then spread about 20 bags of mulch.

By the time I’m finished just like yesterday my shorts and shirt are soaked with sweat🤣

10 years ago, almost all houses here did NOT have AC. No real need. Our house built in 2014, nope. We added it in 2021. Very worthwhile add (heat pump for aux shoulder heat and AC).

Ima think on this one.

I don't see a ridge vent along the top Pablo. I would think that a ridge vent should take care of the heat buildup.

Contrary to what the ridge vent and shingles manufacturers (e.g., GAF, Owens Corning, etc.) want you to believe with their product marketing propaganda, ridge vents do a very poor job of allowing air movement via convection motion. To effectively displace the hot air trapped in an attic/enclosed roof space, active forced air ventilation is vastly superior.

My house originally had two passive turbine style vents in the roof and summer attic temperatures were ~120 degrees F. When I had a new roof installed in 2015, the GAF Gold Class roofing contractor convinced me to replace the turbines with the GAF ridge vent system and to add 10 additional under eave supply vents to validate the 50 yr. warranty on the architectural shingles. The attic temperature INCREASED to ~140 degrees F (even with lighter colored shingles) in the summertime. After several summers, I installed two powered ventilator fans where the turbines were previously located and the temperature now peaks at 115 degrees F in the attic.

Ridge vents are promoted by roofing contractors because the materials are inexpensive and the installation process requires minimal labor. It is a high profit margin up-sell product similar to a car dealership pushing engine air filter or cabin air filter replacement for $80 a pop.
