Wildfire Defense Mesh
Wildfire Defense Mesh helps forward-thinking roofing companies turn wildfire mitigation into a high-value differentiator. In a market where a Class-A roof is the baseline, the most serious contractors understand that the real threat is often what’s left exposed: vents, eaves, soffits, and roofline openings where wind-driven embers enter and ignite homes from the inside out. We provide a specially wildfire-engineered stainless steel mesh that allows crews to harden a home without overcomplicating the job. For companies looking to elevate their offering, Wildfire Defense Mesh delivers value for crews and the bottom line. It’s a roofer-friendly system designed to integrate seamlessly with the eave, soffit, and roofline details you already install. If your team can install a vent, they can install WDM. That means you can deploy “Wildfire Ready” upgrades on new construction, re-roofs, or retrofits with minimal training and no new hires. By addressing the leading cause of home ignition, you move your business beyond price-per-square commodity bidding and into the role of a proactive risk-reduction partner. This approach supports stronger, more profitable bids while giving homeowners confidence that their roof is prepared for wildfire season. As insurance requirements and WUI codes continue to tighten, Wildfire Defense Mesh provides a technical edge. Beyond fire protection, our rugged stainless steel design delivers long-term durability and effective pest and rodent exclusion—outperforming standard hardware cloth through seasonal cycles. Together, we help make home hardening a scalable, professional, and profitable standard for contractors who take their craft and communities seriously.
