Glendale Roof Pros provides professional attic ventilation & ember-resistant vents in Glendale, CA for residential and commercial properties across the Verdugo Valley. This is the page where Glendale gets a different answer than almost anywhere else. Ventilation practice wants air moving through your attic. Wildfire practice wants openings closed. On a hillside street here the resolution is usually fewer vents rather than more.
The conventional fix is soffit intake plus ridge exhaust, sized at one square foot of net free area per 150 or 300 square feet of attic floor. It works, and it is what we would install in most of the country. Inside a Very High Fire Hazard Severity Zone it also builds an ember path from the eave straight into the attic. The physics is fine and the risk profile is wrong.
So we begin by deleting the eave intake. California's wildfire provisions restrict vents in eaves and cornices for good reason, and any vent that stays gets replaced with a unit listed to resist ember entry under ASTM E2886, or covered with noncombustible corrosion-resistant mesh no larger than an eighth of an inch. Quarter-inch screen is not a substitute. Listing labels get photographed and go straight into your file.
Then we relocate the rest. Off-ridge vents on the leeward plane. Listed ridge vent with an internal baffle and external ember screening. No gable louvres facing the slope. Placement matters as much as product here, because the wind driving embers arrives from a predictable direction on most of these streets, year after year. We look at where your last ember event came from before choosing a location.
When the geometry cannot supply enough listed net free area, the honest answer is an unvented conditioned attic. Air-impermeable insulation against the underside of the deck, no attic vents at all, and the assembly detailed to keep the sheathing dry. It costs more than a ridge vent and it removes the failure mode outright rather than screening it. It is also the only approach that survives a code update without rework, and plan checkers understand it.
We will not simply add vents to fix a hot attic here without asking what else could do that work. A radiant barrier, deeper insulation at the ceiling plane and a cooler surface color all pull attic temperature down without opening a hole in the fire envelope. Sometimes the vents are the last thing to change. Fewer holes, better insulation, cooler attic: that is the order we work in.

Materials, equipment and how we do attic ventilation & ember-resistant vents
The difference between attic ventilation & ember-resistant vents that lasts and attic ventilation & ember-resistant vents that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with Class A assemblies verified against the listing number, Vents listed to ASTM E2886 for ember resistance, Eighth-inch corrosion-resistant noncombustible mesh, 72-pound mineral-surfaced cap sheet, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Glendale job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in the Verdugo Valley means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
