Colorado’s lush forests are part of what makes the state beautiful. They also increase the risk of wildfires. Knowing the warning signs is essential for protecting yourself and your property. Even if you don’t live in a remote or heavily wooded area, here are the five warning signs you need to know for wildfire risk in Colorado.
1. Proximity to a Wildland-Urban Interface Area
The wild and urban interface (WUI) is an area where homes and other developments meet or intermingle with natural vegetation. If your property borders or sits near forests, grasslands or foothills, it may be located within the WUI.
Living near a WUI doesn’t automatically put your home in danger. However, wildfire behavior in the surrounding landscape can have a greater influence on your property and may increase your home’s wildfire risk score.
Although many wildfires are caused by human activity, they can also occur naturally to help maintain healthy forests. Therefore, you need to ensure your home is well-adapted to its environment. You can learn more about your location by reviewing the Colorado WUI map or the Colorado wildfire risk map.
2. Little Defensible Space Around Your Home
Defensible space is the area between your home and the surrounding vegetation that helps reduce the chance of wildfire spreading to the structure. When this space is limited or poorly maintained, wildfire risk can increase — particularly during dry and windy conditions. In fact, Colorado’s wildfire resiliency code requires properties in certain areas to maintain defensible space.
You may notice vegetation growing close to siding, tree branches extending over the roof or combustible ground cover near decks and fences. All of these reduce defensible space and are common warning signs of wildfire risk around homes in Colorado Springs and nearby communities.
Effective defensible space is usually organized into three zones based on the distance around each structure on your property:
- Zone 0 extends five feet from your home or structure. This area requires the most attention, and you should keep it as free as possible of combustible materials.
- Zone 1 extends up to 30 feet from your home. Reduce dead plants and overhanging branches, space out vegetation and flammable items like patio furniture, and avoid storing wood piles in this zone.
- Zone 2 extends 30 to 100 feet from your home or property line. This area focuses on slowing fire spread by maintaining vertical and horizontal spacing between vegetation.
3. Unprotected Attic and Ventilation Openings
During a wildfire, embers may pose a greater threat than direct flames, as wind can carry them long distances. If your vents are open or lack proper screening, embers may enter attics or crawl spaces and ignite materials out of sight. This vulnerability is easy to overlook and often goes unnoticed until homeowners check a wildfire warning map during fire season. To reduce your wildfire risk, regularly check these openings.
4. Flammable Exterior Materials
The materials on your home’s exterior can affect how it responds during a wildfire. These include roofing, siding, decking, fencing, and gutters.
If you have older roofing materials, untreated wood features, or debris buildup, you must prioritize routine cleaning and maintenance. However, well-maintained properties can still face a higher risk because certain exterior features increase the potential for ignition, even when not immediately obvious.
Therefore, it’s a good idea to use mitigation strategies to reduce risk. Research shows you can reduce wildfire damage by 50% by implementing home hardening. These may include fire-resistant roofing and siding materials or upgrading to double-paned, tempered-glass windows, which are less likely to break during a fire.
5. Limited Emergency Planning Features
You may notice that there are more wildfire warnings today compared to previous decades. This is because wildfires in Colorado have increased in both size and frequency since 1990.
You don’t need a complete home renovation or upgrade to improve your emergency planning features. Start by making sure your address signage is clear and visible so emergency services can locate your home more quickly. Ensure the address numbers are at least four inches tall, reflective or illuminated, placed on a contrasting background, and easy to spot from the street in both directions of travel. You can also improve access by maintaining a driveway clearance of at least 12 feet wide and 13.5 feet tall.
As part of your emergency planning, it’s also essential to learn the meaning of wildfire warnings, which generally include red flag warnings, fire weather watches, and extreme fire behavior.
Mitigating Wildfire Risks for Colorado Homes
Addressing these warning signs can help you better understand your home’s wildfire exposure and take meaningful steps before conditions worsen. If you’re buying or selling a home in Colorado, a professional home inspection is a smart first step, not to assess wildfire risk, but to understand the full condition of the property you’re investing in.
