Roof Types / Drip Edge
Drip Edge
The L-shaped metal at your roof edge that directs water cleanly into gutters.
Drip edge is an L-shaped metal flashing installed along the eaves and rakes (sides) of your roof. It creates a clean break between the roof edge and the fascia board, directing water runoff into the gutters rather than allowing it to seep behind the gutter or run down the fascia. Drip edge is typically made from aluminum or galvanized steel and is installed beneath the underlayment at the eaves and over the underlayment at the rakes.
Why It Matters
Many Bay Area homes built in the 1950s through 1970s were constructed without drip edge — it was not required by code at the time. Without it, water wicks back under the roofing material along the edges, causing fascia rot, soffit damage, and even foundation erosion over time. Installing drip edge during a re-roof is inexpensive (typically $300-$600 for a standard home) and provides decades of protection. It is now required by California building code on all new roof installations.
