Ember-Resistant Vents and Gutters
Attic and foundation vents are the most common way embers get inside a house. Fine metal mesh stops them at the opening, and noncombustible gutter covers keep dry leaves off the roofline.
[ 01 ]The problem
Why this layer matters.
Wind-driven embers are pulled into attics through soffit, gable and foundation vents, where they land on dust, insulation and framing. Gutters full of leaves become a line of kindling along the roof edge. Both are fast, affordable fixes with an outsized effect on whether a house survives.
[ 02 ]How we install it
Specified by firefighters. Built by craftsmen.
Every install follows the same four steps and ends with documentation for your insurer.
Survey
We count and measure every vent and map gutter runs and roof valleys.
Specify
We choose ember-resistant vents with 1/16 to 1/8 inch metal mesh that keep proper airflow.
Install
Old vents come out, new ones go in, and gutter covers are fitted along every run.
Verify
We photograph each opening for your readiness report.

[ ? ]FAQ
Vents and gutters questions.
Still deciding? Call or text 310-569-4523.
Will new vents reduce attic airflow?
No. We size vents to keep required ventilation while blocking embers.
Are gutter covers enough on their own?
They help, but they work best alongside vents, a clear five-foot zone and treated eaves.
Do I need permits?
Usually not for vent replacement. We handle any permit your city requires.
