Opinions on new roof ridge vent

[Dennis S]

I'm probably going to reroof the house with architectural shingles. I'm wondering about a ridge vent. The house is a basic elongated cracker box. There are round vents on each gable about 12" in diameter.

more vents. always more vents. the cooler it is up there, the longer the roof lasts as it it not baking from underneath. And you aren't heating the house as that heat crawls down the walls through the drywall and studs.

You don't say where the house is but, generally speaking, YES have PROPER VENTILATION installed. It will make for a MUCH more comfortable house.

Ventilation is primarily about moisture mitigation.

An old construction saying:

Insulation without ventilation leads to perspiration.

South Arkansas. Lots of heat and humidity and lots of sun directly on the house since the trees are gone.

Does the air intake area need to equal or be a little greater than the roof ridge outgoing area?

"It’s important to remember that it’s better to have too much intake ventilation than too little – and many homes often undercalculate the amount of intake needed — so worry less about having too much intake and err on the side of having more."

I'm in Nashville (humid and heat too) and roof people whom I know and trust more than others recommended a ridge vent as the most effective. So far no problems for a ranch style home.

If you don't have soffit vents to allow air to come in you might consider adding those when reroofing.

Are exhaust fans still a thing?
