02 Retrofits with the best payback for a typical home
| Retrofit | Installed cost | Simple payback | Lifetime NPV |
|---|---|---|---|
| Ember-resistant vents & soffits Most homes ignite from embers entering attic and crawlspace vents, not the flame front. Mesh and baffle retrofits close that path. |
$1,000–$4,000 | 8.4 yrs | $2,128 |
| Defensible space & ember-resistant zone Clearing the 0–5 ft zone and managing vegetation to 30 ft — the highest-leverage, lowest-cost wildfire action. |
$500–$3,000 | 4.6 yrs | $1,367 |
| Pipe insulation & freeze protection Insulating exposed runs and adding heat tape where needed — burst pipes are the #1 winter-storm claim. |
$300–$1,200 | 10.2 yrs | $247 |
