“The one question I ask every roofing client that nobody else asks: what's your attic ventilation situation? In LA, an unventilated attic adds 15–20°F to your home's interior temperature and significantly shortens shingle life. Before we replace a roof, we assess the ridge and soffit venting and fix it if it's inadequate. It adds $800 and makes the roof last 5–8 years longer.”
Verify drip edge specification before signing any roofing contract. Drip edge is a metal flashing that goes along the eaves and rakes before the underlayment. It's code-required and frequently omitted by budget contractors. Without drip edge, water enters behind the fascia during wind-driven rain events.
The most common roofing mistakes in Northridge are: selecting a contractor based on price alone without verifying CSLB license and insurance, approving change orders verbally rather than in writing, and starting work before permits are issued. All three create financial and legal exposure that's avoidable with careful contractor selection and contract management.
