Wildfire & Ember Screens in San Francisco: common questions
What mesh size is required for wildfire ember protection?
Corrosion-resistant metal mesh with openings no larger than 1/8 inch and no smaller than 1/16 inch. Larger openings let embers through; smaller ones clog with debris and restrict required venting. Fiberglass mesh does not qualify — it melts.
Does California Chapter 7A require me to retrofit my existing home?
Not statewide, as of now. Chapter 7A governs new construction and major remodels in Very High Fire Hazard Severity Zones. For an existing home, ember-resistant vents and screens are voluntary — but they are among the highest-value hardening steps, and insurers increasingly ask for them.
What does ember-resistant screening cost in San Francisco?
Whole-house vent and opening screening typically runs $500 to $2,500 depending on vent count and access. Full ember-resistant window screens on an opening-by-opening basis land closer to $1,300–$3,600 per opening when they also carry a security rating.
Can one screen handle both fire and break-ins?
Yes, and that combination is worth paying for. A 316 stainless mesh system that carries both a forced-entry test report and a WUI listing does two jobs with one install. Few contractors offer it — this ranking shows which ones do.
