Is a ventilated roof installed the same way as a normal tile roof?
No. Although most of the installation is the same, a ventilated roof is installed differently in the ridge. See the section on ventilated roofs on this website and review the ridge pictures. A ventilated roof requires air to pass through the ridge. Traditional ridge installation uses mortar to bind the ridge tiles to the ridge, this let no air through. Gambale’s preferred ridge installation involves a wooden beam at the top of the ridge, a roll of self adhering aluminium foil and mesh and special hooks. The process is quicker and cleaner than the traditional mortar method. But it is not used in high wind areas so check your local code before installing a ventilated ridge.
