How Rodents Compromise Your Attic’s Integrity


When you hear scratching, scurrying or chewing sounds coming from above your ceiling, your first thought is usually annoyance. But rodents in the attic are not just that, they are actively and rapidly compromising the structural integrity, energy efficiency and safety of your entire home. The damage they inflict is often hidden, unseen and far more extensive than simple noise pollution.

At Above Board we understand that a complete solution requires more than just trapping. Our services focuses on attic rodent remediation and attic insulation removal and refit because the destruction these pests leave behind must be professionally cleaned and repaired to restore your attic’s function.

The most significant and costly damage rodents cause is the destruction to your insulation. Rodents view insulation materials as soft and warm nesting materials. As rodents burrow, travel and nest, they compact the insulation. Insulation relies on air pockets to provide its thermal resistance, so when these air pockets are crushed the material’s ability to resist heat flow plummets. This means the conditioned air you pay for rushes out and unconditioned air rushes in, resulting in drafts and high utility bills.

Rodents also constantly urinate and defecate. This waste not only introduces severe biohazards into your home’s air supply, but also saturates the insulation. Wet or soiled insulation loses its thermal performance entirely, leaving a contaminated mess that requires specialized attic insulation removal.

Beyond the insulation damage rodents pose serious safety risks, specifically related to fire.

Rodents have an innate instinct to chew to keep their teeth worn down. The electrical wiring running through your attic? Just so happens to be its favorite target. They chew through the protective plastic sheathing, exposing the live copper wire underneath. This expired wiring can short-circuit or create sparks. And because this wiring are often nestled inside dry, flammable nesting materials like shredded insulation, this chewing creates a fire hazard. A rodent-chewed wire is one of the leading preventable causes of electrical fires at home.

While insulation is often the first thing to go, rodents also attack the physical structure of your home, though often on a smaller, cumulative scale. They chew on wood framing and trusses, which can weaken support structures over time, particularly at entry points. Additionally rodents chew holes through crucial materials like plastic vapor barriers, allowing moisture to condense and promoting wood rot. They also tear through flexible HVAC ductwork, letting cooled or heated air leak into the attic and further lowering your system’s efficiency.

Dealing with a rodent infestation is a two-step process. First, elimination and exclusion and second, full remediation of the damage.

Above Board provides comprehensive attic rodent remediation, which includes safely removing the existing rodent population, sealing all external entry points to prevent future access and meticulously clearing out all contaminated insulation, feces and nesting materials. Once the space is safe and clean, we perform a full attic insulation refit with new, high-efficiency insulation, restoring your home’s thermal envelope and energy savings.

Don’t let unseen damage compromise your home’s safety and value. Contact Above Board today for a professional attic inspection and comprehensive remediation plan.
