The Heat Is On: Here are 5 Easy Ways to Upgrade Your Home's Defences Against Fires

24.07.2025 13:00

Wildfires and structure fires once felt like edge‑case catastrophes. Then came record‑setting fire seasons, casting doubt on current fire prevention methods. Fires, big and small, are now officially everyone's problem. Especially for those who want to use their open flame gadgets out back.

The good news is you don’t have to reconstruct your home into a concrete fortress to tilt the odds. Integrating a few proven architectural upgrades can mean the difference between a close call and a smoking insurance claim. Below is a playbook that blends building science with hands‑on practicality, so you can still brag about your marvelous home and sleep easily when the dry winds kick up.

Start Easy & Quick: Ember-Tight Vents

Embers smaller than a dime can blow in through conventional 1/4-inch mesh. Swap in 1/8-inch corrosion-resistant "fire screens" or mesh to prevent any unwanted firey guests. Vulcan Vents has made vents of all types for your home that expand and seal under heat. This lets your less flammable siding do its job and stave the fire off. An easy weekend job and a massive fire risk reducer.

Siding That Doesn't Feed Flames

With your new vents blocking off your flammable interiors, don't shy away from beefing up your main defence, your siding. Skip the combustible wood and plastic vinyl and go for the more fire-resistant options like fiber-cement boards. One such option is Hardie Plank Lap Siding. This siding is non-combustible, pest-free, and moisture resistant. It is more than a DIY task, but good to keep in mind when your siding eventually needs replacing.

Defensive & Smart Landscaping

Forget the medieval moat aesthetic. You can still have a beautiful yard that won't burn easily. The UC ANR Fire Network has created some guidelines for your next landscaping project. Start at the house and work outwards.

Within Zone 0 (0-5 feet from your home), "Avoid anything combustible in this zone: woody plants, mulch, woodpiles, combustible trellises, and stored items. Zone 0 is an excellent location for walkways, hardscaping with pavers, rock mulch, or pea gravel. Zone 0 should be coupled with a 6" vertical noncombustible section at the intersection between the ground and the exterior siding."
Within Zone 1 (5-30 feet from your home), it "should be 'lean and clean'. The goal is to eliminate fire paths between vegetation by increasing the spacing between trees, removing lower branches of trees and shrubs, and creating separations between vegetation groups. Plants should be properly irrigated and maintained to remove dead/dry material."
Within Zone 2 (30-100+ feet from your home), "the goal is to moderate potential fire spread and flame height by reducing the density of trees, shrubs, and herbaceous plants or grasses. Shrubs and trees should be well spaced and pruned to eliminate fuel ladders. If Zone 2 extends over your property, prioritize implementing the recommendations for Zones 0 and 1. After completing these actions, connect with neighbors, HOA, or Fire Safe Councils to address concerns in your community."

The Roof Is a Landing Pad for Embers

Another easy task for the family on the weekends can be making sure your roof is clear of debris and gutters are empty. This helps prevent the chance of debris catching fire and setting your home alight. Look for areas that accumulate debris and take note to check those more frequently, especially if there is a fire nearby.

Another important factor is keeping your roof in good condition. If your roof is damaged, it increases its vulnerability to fires, so if you notice something, get it repaired by a professional. How should you get it repaired? I'm glad you asked.

According to Fire Safe Marin, "Common Class A roof coverings include asphalt fiberglass composition shingles and concrete or clay tiles. Some materials have a 'by assembly' Class A fire rating, meaning that additional materials must be used between the roof covering and the roof sheathing in order to attain the fire rating. Examples of roof coverings with a 'by assembly' fire rating include aluminum, some fire-retardant wood shake products, and recycled plastic and rubber products." Class A designation is the most fire-resistant and should be the top choice to help prevent serious fires.

Fence Off The Fire

Another easy way to prevent fires is by simply avoiding placing flammable materials at the base of your fence. This means clearing debris, limiting the use of mulch, and maintaining your fence.

If you are looking for an upgrade, here is what you should know. Non-combustible fencing and gates do exist, and they can work wonders. "Using non-combustible fencing/gates where they attach to the building reduces the opportunity of a burning fence or gate igniting the exterior of the structure." In addition, Fire Safe Marin also says, "A fence design that allows for greater airflow, such as a single panel lattice fence, makes it more difficult for wind-blown embers to accumulate."

Key Takeaways

Check and replace any vents that don't meet the 1/8-inch mesh fire standard. Most homes will have 1/4-inch vents, so this is an important one. It's an easy fix, too!
Strive to have siding on your home that is as fire-resistant as possible. Untreated wood and vinyl won't cut it anymore and need to be replaced more frequently too.
Landscape with fires in mind. Your home will look beautiful either way, but only with mindful landscaping can you slow down approaching fires.
Keep your roof clean, and when it needs repairing, take it seriously. There are fire-safe options; all you must do is seek them out.
Don't let your fence be your downfall. Upgrade and clean your fence as best you can so it doesn't lead a fire straight to your home.
