Are Hidden Attic Problems Putting Your Vegas Family at Risk?

The metal flue that carries combustion gases from your furnace and water heater out through the roof is supposed to be sealed at every joint. After 15+ years of thermal cycling in a Vegas attic, those joints loosen, the flue separates, or the cap rusts through. Combustion gases — including carbon monoxide — vent into the attic instead, where they can drift into living space through ceiling penetrations.

Vegas attics see more rodent activity than most homeowners realize. Once mice or roof rats find a way in, they nest in insulation, chew wiring, and leave urine and droppings that work their way into your air through unsealed duct seams. The contamination becomes a respiratory irritant — and the chewed wiring becomes a fire risk you only notice when something stops working.

Homes built before 1985 often have older insulation materials — some containing asbestos — that degrade over time. Replacing them with modern attic insulation restores both safety and efficiency. When the air handler is in the attic (most Vegas homes), microscopic fibers can be pulled into the system through unsealed cabinet seams. You’d never see it, but the family breathes it every time the blower runs.

The small caps and screens over your attic vents keep birds, bats, and palm rats out. When they break — and in Vegas wind they do break — the attic becomes a wildlife corridor. We’ve found pigeon nests, bat colonies, and rat populations all settled directly above living spaces, sometimes undisturbed for years before anyone thought to look.
