On a Topanga addition, our attention goes first to the joint where the new roof ties into the old one. In mountain country that joint takes dry wind, strong sun, the odd hard storm and, during fire season, blowing embers. We join the two roofs with metal flashing and a Class A covering, then close in the eaves, so the bedroom or family room you add stays dry inside and sealed against sparks.

Permits through the county

Topanga is unincorporated, so Los Angeles County reviews and permits an addition there. County plan check looks at setbacks, height, fire department access and the structural design, and parts of the area are mapped for fire hazard, which brings ember-resistance requirements into the review. If the lot slopes, a soils or geology report may be requested before approval. We gather what the county asks for at the outset, so the drawings move through review with fewer rounds of comments and the family can plan around a steadier schedule.

Ember-resistant from roof to deck

Embers ride ahead of a fire and land in vents, gutters and gaps. For a new room on a mapped lot, we use noncombustible siding or stucco, vents screened with fine metal mesh, tempered glazing and boxed eaves. Gutters get guards, and the strip of ground beside the new walls is kept clear of mulch and plants that catch easily. Any new deck uses fire-rated boards. These details are drawn into the plans, so they are reviewed together and built together.
