While "the two vents" can vary depending on your specific house layout, homes typically feature two functional categories of roof vents: Attic Vents (which keep the roof structure healthy) and Appliance/Plumbing Vents (which vent exhaust from inside the house).
Intake vents in your soffits or eaves allow fresh air to flow into your attic. Exhaust vents, usually found at the roof ridge gap or gable ends, release warm, moist air back into the environment and out of your attic. This constant airflow in and out of your attic helps regulate temperature and humidity levels.
In most residential cases, ridge vents are better than whirlybirds. Ridge vents provide even, passive airflow across the entire roofline and are virtually invisible. Whirlybirds (turbines) are cheaper and work well in high-wind, open environments, but have moving parts that can break, squeak, or stall.
Blocked soffit vents disrupt your roof's intake ventilation, halting the continuous flow of fresh air through your attic. This creates a domino effect of serious issues:
Number 2 is a vent for an exhaust fan like those found in bathrooms and laundry rooms. They exhaust moist air to the outside. 3. Number 3 is a vent for an attic space, called a “roof vent” or “turtle vent.” They release hot air from the attic.
While roof tile vents are designed to keep your home dry and safe, they can sometimes develop leaks. These leaks can occur due to various reasons, including: Poor Installation: If roof tile vents are not installed correctly, gaps can form between the vent and the surrounding tiles, allowing water to seep through.
Whirlybirds typically last between 10 to 15 years on average. However, high-quality models, like Colorbond or steel turbines, can last upwards of 20 years if properly maintained and installed.
Roof vent caps are designed to prevent rain, snow, and pests from getting in - but they can also trap lint. If not cleaned regularly, this can lead to complete blockages.
Yes, mice can absolutely get in through soffit vents. Because mice are incredibly agile climbers and can squeeze through openings the size of a dime (about a 14one-fourth14-inch gap), they easily climb up walls and enter attics through damaged, warped, or widely-spaced vent covers.

For a 2000-square-foot house, you generally need about 6.5 to 13.5 square feet of total Net Free Area (NFA) ventilation. This usually translates to roughly 6-7 standard roof exhaust vents (if using 14"x16" vents at 144 sq in per vent) or a 24-foot ridge vent, combined with 24 feet of soffit intake vents.
People have moved away from using electric attic fans (and whole-house fans) because modern building science revealed they often do more harm than good. Instead of cooling the house, they frequently pull conditioned, expensive air from your living space and introduce dust or humidity into your home.
Classic, neutral roof colors like charcoal gray, slate black, and weathered wood brown consistently provide the best return on investment. These timeless shades maximize your home's value (often by 3% to 5%) because they complement nearly any exterior color scheme and appeal to the broadest pool of potential buyers.
Yes, mice absolutely can get into your vents and ductwork. Because mice have flexible skeletons, they can easily squeeze through tiny openings like loose floor vent covers, gaps in wall vents, and unprotected dryer vents.
No, roof vents do not make the actual living space of your house colder in winter. Their purpose is to keep the attic cold. If your living areas feel cold in the winter, the issue is usually inadequate or damaged insulation, not the roof vents.
The cheapest time to get a new roof is during the late fall and winter months (November through February). Because demand drops significantly, contractors typically offer off-peak discounts or are much more willing to negotiate on labor to keep their crews working.
Roof rats are most active during the warmer months when food is abundant, but they can remain active year-round in milder climates. Cooler weather often drives them indoors, where they forage for food and shelter.
The Amish control mice through non-chemical, self-sustaining methods, relying on active trapping, natural scent repellents, and structural exclusion. Rather than using commercial poisons, they focus on physical barriers and natural predators to keep rodent populations in check.
Scratching in your roof or ceiling is typically caused by wildlife. The exact culprit depends on when you hear the noise and how loud it is:
To quickly tell if your plumbing roof vent is clogged, listen for loud gurgling sounds in your sinks or toilets, or watch for unexpected fluctuations in your toilet bowl's water level. A blocked vent creates negative air pressure that starves the drainage system, slowing water flow and pulling air from nearby traps.
The best time for duct cleaning is during the spring or fall shoulder months. Because professionals must turn off your HVAC unit, you want mild weather so you aren't stuck dealing with extreme hot or cold temperatures while the service takes a few hours to complete.
Yes, it is perfectly okay to never clean your air ducts under normal circumstances. In fact, the US Environmental Protection Agency does not recommend routine duct cleaning, noting it is usually an unnecessary expense.
Whirlybirds themselves do not leak when they are properly installed, flashed, and maintained. Their design deflects rain. However, leaks can occur if the surrounding base flashing, roof cement, or pop rivets fail, or if debris prevents the turbine from spinning.
A 20-year-old roof is considered to be at or near the end of its typical lifespan, particularly for standard 3-tab asphalt shingles. While it may not be instantly failing, it is entering a high-risk zone for leaks, insurance issues, and needed replacement, making a professional inspection essential.
Maple trees are the primary source of the spinning seeds commonly known as "whirlybirds" or "helicopters". Scientifically called samaras, these seeds feature a papery wing attached to a seed pod that allows them to twirl through the air.
