Fire-Resistant Siding & Exterior Wall Upgrades
Exterior walls face radiant heat from nearby burning vegetation and direct contact from material burning against the structure. Siding work for wildfire focuses on material choice, the bottom edge of the wall and the transitions where siding meets other assemblies.
What matters on a wall assembly
- Noncombustible or fire-resistant siding materials
- Adequate clearance between siding and the ground or hardscape
- Sealed joints, gaps and penetrations
- Transitions at decks, fences and attached structures
- Condition of existing wood siding, trim and fascia
Partial upgrades
Full re-siding is not always necessary. On many homes, the highest-value work is limited to the lower portion of walls, exposed elevations facing slope, and the transitions where combustible attachments meet the building.
