Hello everyone! I'm builiding my first home and have tons of questions. The delima currently is ridgevents. My trusses span 40'. The middle of my home has a scissor trusses with 20' being vaulted. The house is 63' long. The vaulted part is 27'x20'. The garage attaches to the home, so it has an offset T shaped ridge. It also has a front and back porch, both 12'x12' under the same roof. Is a ridgevent suitable for this roof? If so, Do I install a ridgevent over the vaulted area? The roof is going to take S style concrete tiles. Is there a special ridgevent for that? Thank You.
In comparison to asphalt/fiberglas shingles most everything you use for the tile installation is special, because it has a much higher profile.
Ridge vents are arguably the best exhaust ventilation to use,
everyone agrees it's the best exhaust system for over vaulted/cathedral ceiling area's.
If your using traditional insulation 'not foam' make sure you install baffles/air chutes not only at the eaves in those areas but all the way to the top of the ceiling where it opens up into the dead space/crawl space near the ridge.
Edited: Ask the folks at the supply house/store where your purchasing the tile for spec's on installation, this should include underlayments, flashing's, tile install, ventilation, etc.
