Wildfires risk in Missouri

Wildfire Characteristics in Missouri

Missouri's diverse landscape—from the northern plains to the forested Ozark Highlands—shapes its wildfire risk. Overall, the state has a low wildfire hazard, rated Level 1 out of 5 in federal risk assessments. However, wildfires do occur, primarily as brush and grass fires during dry periods. The risk is not uniform; the Ozarks region, with its extensive oak-hickory forests and rugged terrain, is the most exposed. Other rural areas with grasslands and open woodlands can also see fires, especially where human activity meets wildland vegetation.

Wildfire season in Missouri typically peaks in spring (March to May) and fall (October to November), when vegetation is dry, humidity is low, and winds can spread flames quickly. Summer can also bring fire risk during drought conditions. Most wildfires in Missouri are human-caused—from debris burning, equipment use, or arson—though lightning can ignite fires as well. According to the National Interagency Fire Center, Missouri experiences hundreds of wildfires each year, but the vast majority are small and contained quickly by local fire departments and the Missouri Department of Conservation.

The Missouri State Emergency Management Agency (SEMA) coordinates statewide response and works with local agencies to manage fire risk. While large-scale evacuations are rare, smoke from wildfires—both in-state and from other regions—can affect air quality and pose health risks, especially for children, the elderly, and those with respiratory conditions.

How It Affects Homes

Even a small wildfire can damage homes. The most common impacts include:

• Structure fires: Homes near wooded areas or grasslands can be ignited by flying embers or direct flame contact. Decks, roofs, and siding are particularly vulnerable, especially if they are made of wood or other combustible materials. Embers can travel more than a mile from the main fire, igniting spot fires around your home.
• Smoke damage: Smoke can infiltrate homes through vents and cracks, causing respiratory issues and leaving soot and odors that require professional cleaning. Smoke damage can be extensive even if the fire itself does not reach the home.
• Landscaping loss: Fires can destroy trees, shrubs, and lawns, leading to erosion and costly replanting. The loss of vegetation can also increase the risk of flooding after a fire.

Standard homeowners insurance policies typically cover wildfire damage, including structural damage and personal belongings. However, coverage for smoke damage may vary, and some policies may have exclusions or require additional riders. In high-risk areas, insurers may require mitigation steps or charge higher premiums. It's important to review your policy, document your belongings with photos or videos, and consider additional coverage if you live in a high-risk area. The Ready.gov wildfire page offers guidance on insurance and recovery.

How to Prepare Your Home

Taking proactive steps can reduce your home's vulnerability to wildfire. Here are key mitigation measures:

• Create defensible space: Clear leaves, pine needles, and other debris from your roof, gutters, and deck. Remove flammable vegetation within at least 30 feet of your home, and keep trees and shrubs pruned and spaced.
• Use fire-resistant materials: Install Class A roofing (such as asphalt fiberglass composition, metal, or tile), and use non-combustible siding, decking, and fencing where possible. Enclose eaves and soffits.
• Screen vents and openings: Use 1/8-inch metal mesh to cover vents, chimneys, and under-eave areas to block embers from entering your home.
• Maintain your landscape: Keep grass short and well-watered. Choose fire-resistant plants (such as succulents or deciduous trees) and space them to slow fire spread. Avoid planting highly flammable species like pine, eucalyptus, or juniper near your home.
• Keep firewood and propane tanks away: Store firewood stacks and propane tanks at least 30 feet from your home, and remove branches overhanging your roof and chimney.
• Prepare an emergency kit: Include water, food, medications, and important documents. Have a family evacuation plan and practice it regularly.
• Stay informed: Sign up for local alerts and monitor fire conditions through the Missouri SEMA and local authorities. Follow burn bans and restrictions.

Frequently Asked Questions

Is wildfire risk increasing in Missouri?

While Missouri's overall risk remains low, climate variability can lead to more frequent drought conditions, which may increase wildfire potential. However, large-scale fires are still uncommon compared to western states, and the state's fire agencies are well-prepared to respond.

Does homeowners insurance cover wildfire damage in Missouri?

In most cases, yes. Standard homeowners insurance policies typically cover wildfire damage, including smoke damage. However, it's wise to check your specific policy and consider additional coverage if you live in a rural or forested area. Some insurers may require a separate wildfire endorsement.

What should I do if a wildfire is approaching my home?

Follow evacuation orders immediately. If you have time, close all windows and doors, remove flammable window coverings, and turn off gas utilities. For more tips, visit Ready.gov.
