Protecting Your Home from Embers with Gutter Retrofits:
Gutters are a critical but often-overlooked component of wildfire defense. When debris like leaves, twigs, and pine needles accumulate in gutters, they create a prime fuel source for flames and embers. During a wildfire, these materials can easily ignite, leading to fire spreading along your roofline and putting your home at significant risk. Installing ember-resistant gutter systems, including noncombustible gutter covers, and keeping them clear of debris is crucial for preventing fire intrusion. By prioritizing gutter maintenance and retrofitting, you enhance your home's defenses against wildfires, creating a safer environment for your family and property.

Key Points:
- Gutter retrofits prevent embers and debris from igniting your roof.
- Use noncombustible and corrosion-resistant gutter covers and systems.
- Replace damaged or combustible gutters entirely.
- Follow building code guidelines for gutter materials and installation.
This section outlines how to strengthen your home's gutters against wildfires according to California's Wildfire Mitigation Program Code. Here's a breakdown:
Roof Gutter Cover Retrofit:
- Repair or replace damaged gutter covers to prevent leaves and debris from accumulating. Debris can ignite from embers or flames and spread fire to your roof deck or fascia boards.
- Replace existing covers with noncombustible and corrosion-resistant materials. If available, use a cover with an integrated metal drip edge for better water flow.
- If a noncombustible cover cannot be installed over your existing gutter system, refer to the "Roof Gutter System Retrofit" section.
Roof Gutter System Retrofit:
- Replace damaged or combustible gutter systems with a new, noncombustible, and corrosion-resistant system. Combustible gutters can catch fire and spread flames to your roof deck, fascia boards, or other nearby combustible materials.
- New gutters should be made of noncombustible and corrosion-resistant materials, with a minimum thickness of 0.032 gauge.
- You are responsible for removing and disposing of the old gutter components at an approved disposal site.
- The color of the new gutters should match the existing building components for a cohesive look.
