Check your eligibility for grantsWhat to Look For in Ember-Resistant Vents
Mesh Size & Material
Vents must have 1/8-inch or smaller mesh openings to block embers (typically 3–5mm). Materials should be non-combustible: aluminum, galvanized steel, or stainless steel. Avoid plastic-framed vents; they can melt.
Certifications & Standards
Look for vents tested to ASTM E2886 (Ember Intrusion) or meeting Firewise USA and IBHS requirements. Some insurance companies require specific certifications—verify with your carrier before purchasing.
Ventilation Airflow
Ember-resistant vents restrict airflow compared to standard vents. Verify the Net Free Area (NFA) matches your attic/crawl space requirements. Too restrictive can cause moisture buildup.
Installation & Compatibility
Check if the vent fits your existing roof or wall openings. Some require custom framing. Budget for professional installation ($50–$150 per vent) or DIY if you're comfortable on a roof.
Why Ember-Resistant Vents Are High-ROI
Ember-resistant vents typically cost $30–$100 per vent ($300–$1,200 for a whole house) but address one of the largest vulnerability points. They're often eligible for federal grants, state tax credits, and insurance discounts. Installing them alongside roof, gutter, and defensible-space upgrades compounds your protection and ROI.

View cost guide →Frequently Asked Questions
Do I need ember-resistant vents if I already have a Class-A roof?
Yes. A Class-A roof is excellent, but vents are a separate vulnerability. Embers can still enter through attic and crawl-space vents, potentially igniting insulation or structure. Both upgrades together provide comprehensive protection.
How many vents does a typical house need?
Most homes need 2–8 vents depending on attic/crawl-space size and configuration. Your contractor or home inspector can assess. Total costs typically range $300–$1,200 for a complete retrofit.
Can I install ember-resistant vents myself?
Depends on vent type and location. Soffit and crawl-space vents are often DIY-friendly; roof vents require working at height and may need professional installation. Budget $50–$150 per vent for professional labor.
Do ember-resistant vents reduce attic ventilation and cause moisture problems?
Ember-resistant vents do restrict airflow slightly compared to standard vents. But when properly sized to match your attic/crawl-space needs, they provide sufficient ventilation. Verify Net Free Area (NFA) requirements with your contractor before installation.
Will my insurance give me a discount for ember-resistant vents?
Many carriers recognize ember-resistant vents (especially ASTM E2886 certified) and offer 3–8% discounts. Always verify with your insurer before purchasing; they may have specific product requirements.
