I-Zone Tutorial - Structure Protection

Your roof is the single most vulnerable part of your home during a wildfire. Even with fire resistant class “A” roofing materials, wind driven embers can pile up in nooks and crannies or lodge themselves under eves and enter your attic or crawl space though ventilation vents (more information about “hardening your home” later in the tutorial).

We’ve all seen news footage of homeowners in shorts and flip flops using their garden hoses to try and water down their roofs as a wildfire approaches. Unfortunately, garden hoses are not an effective or safe way of preventing flying embers from igniting your roof. They simply do not have sufficient pressure or flow to provide the reach and volume required. Fire hoses with an adequate water supply are extremely effective.

A simple garden hose delivers about 40 psi of water (about 10-20 gallons per minute). A fire hose can deliver between 70-120 psi (minimum 50-125 gallons per minute).
