After clearing your zones, the next highest-impact work involves the materials your home is actually built with. Some components are far more vulnerable than others, and understanding where embers find their way in can help you prioritize upgrades.
Roofing
Your roof is your home's largest surface area exposed to the sky, and it's where airborne embers are most likely to land. FireSmart Canada's construction guidance identifies the roof as one of the most vulnerable components and recommends Class A fire-rated materials — asphalt fibreglass shingles, metal roofing, clay or concrete tile, or slate.
If your roof is aging and you're planning a replacement, choosing a Class A rated material is one of the most impactful fire-resilience upgrades you can make. If you're not sure where to start with that process, our guide to hiring a roofer in Canada covers what to ask and what a good quote looks like.
Between replacements, keep your roof and gutters clear of pine needles, leaves, and debris. Accumulated organic matter in gutters or valleys is exactly the kind of material that catches and holds an ember.
Siding
FireSmart Canada warns that some siding materials — particularly vinyl — can melt under high heat, allowing flames to reach the underlying wall structure. Stucco, brick, fibre-cement board, and poured concrete all offer superior fire resistance. If your home currently has vinyl siding and you live in a wildfire-prone area, upgrading to fibre-cement (such as HardiePlank) or stucco is worth considering during any planned renovation. A renovation permit may be required depending on the scope of work and your municipality.
Vents, Soffits, and Eaves
Soffit vents, gable vents, and ridge vents are designed to move air — and they also move embers. Standard mesh screening (6mm or larger openings) allows embers to enter your attic space. Upgrading to 3mm corrosion-resistant metal mesh is one of the most cost-effective fire-hardening improvements you can make. Non-combustible fascia and soffits (metal or fibre-cement) provide additional protection for the vulnerable under-eave area.
Decking and Fencing
Wooden decks and fences that connect directly to the house act as fire bridges — they can carry flames from the yard right to your walls. If you're building or replacing a deck, non-combustible or fire-resistant decking materials are the safer choice. For existing wooden decks, keeping the area underneath clear of debris and stored items is critical, since embers that land under a deck can ignite material that's out of sight. Where a wooden fence attaches to your home, consider replacing the first section (the connecting post and panels) with metal or another non-combustible material to break the fire path.
