I'm replacing my roof, and the contractor is offering to install either 50' of ridge vent or 6 roof louvers for the same cost (the current roof has a ridge vent). He strongly prefers roof louvers, saying they work better than ridge vents. Does anyone agree?

They do not cost the same in material or labor. Maybe cheap ridge vent?

50' of ridge vent at 18 sq. in. of Net Free Area per foot = 900 sq. in. of NFA of ventilation.

6 roof louvers at 50 sq. in. of NFA per louver = 300 sq. in. of NFA of ventilation.

Those numbers are assuming Shingle Vent II ridge vent and a standard roof louver.

For the same money I think I would take three times the ventilation.

I like roof vents over ridge vent. On my rental property when I roofed it in 07 I replaced the ridge vent with Lamanco's.

A good friend of mine did the same thing as well. He's been building high end homes for over 20 years. He said that he didn't like how much heat escaped his lake home so one day he cut holes for Lomanco's and couldn't believe how much hot air poored out of the vent openings. He assured me the felt was cut out of the peak.

My father seen with his own eyes 3ft snow drifts in an attic from ridge vents.

As far as 50ft of ridge I'd go with 9 vents. Odd is always easier than even.

As far as vaults you have to do ridge vent, there is no other choice.
