Morris County Roofers: Article About Vented Soffits
Although keeping heating and cooling costs down in a house often relies on eliminating leaks in a home, it is also essential that an attic allow outside air to flow through it. Airflow in an attic can keep a home cooler in the summer and prevent ice dams from forming in the winter. Additionally, it can reduce the chances of water damage taking place.
Ventilation is most commonly achieved with a combination of vented soffits, baffles and ridge vents. Soffits are most commonly made from either aluminum or vinyl, and they keep water and debris out of an attic. They are installed where the roof overhangs the outside wall.
Vented soffits are designed so that the slits or holes in them are at an angle. This keeps water, bugs and animals out, but it allows air in. It is important that baffles are installed in the attic around areas where air comes into the space through soffits.
Baffles are normally made of plywood or a similar material, and they are boards that can be stapled in place. Morris County roofers may install them so that they create pathways for air to move through to the top of the attic without disturbing insulation. Insulation must remain compacted to be effective, and moving it, even just with a breeze, can lower its R value.

Installing baffles around the vented soffits also helps to ensure that they are not blocked and allows people to insulate completely around the area where air is coming into the attic. This keeps heat from moving between the attic and the home or the attic and HVAC ducts, if any are in the space.
Once the air reaches the top of the attic, it will be able to leave through ridge vents. These are openings that are installed at the apex of the roof, and they are covered to prevent anything from entering the attic through them.
Airflow helps ensure that moist, hot air escapes the attic in the summer. If humid air does not leave the attic, it may lead to the development of mold that can damage wooden structures in the area. When hot air cannot leave the attic, its temperature can keep rising up to dozens of degrees hotter than the outside temperature. Airflow in the winter creates natural convection, so the areas where ice dams would normally form have heat moving through them that helps to keep melted snow from freezing again.
