Attic ventilation might seem like a minor consideration, but properly installed, it can extend the life of your homes' attics and roof structures -- saving you many dollars in repair costs -- and saving you from the expensive replacement of a prematurely failed roofing system.
During warmer months, ventilation helps keep attics cool. It helps prevent hot, moist summer air from warping the roof sheathing. It also stops shingles from deteriorating prematurely and prevents the forming of mold. What's more, fresh air in the attic makes a home much easier to cool, which can result in lower energy costs.
In winter months, ventilation helps reduce moisture to keep attics dry. It stops water from backing up under shingles, damaging insulation, and rotting the roof structure itself. It also helps prevent ice dams from forming. Ice dams occur in areas where snowfall and cold temperatures are common and pose a special problem because they prevent melting water from running off of the roof, backing up and possibly deforming rain gutters and downspouts in turn causing damage to walls , foundation and basement waterproofing problems.They can even cause leaks inside the home, resulting in drywall damage. We at Scranton Roofing and Contracting LLC know just how important proper attic ventilation is to the sustained quality of you roofing system and home.
Why is Attic Ventilation Important?
The constant, year-round movement of air across the attic is a process that can improve home comfort, reduce damage to the roof structure and help keep a roofing warranty valid. Every time stale, overheated air is vented out of the home, and fresh air is pulled in to replace it, you have an "air exchange."
The process of air exchange is more than a breeze moving through the home. It's a process that provides a steady, high volume of air movement. It's a system of components, all sized and positioned to create a balanced flow of intake and exhaust air moving though the attic.

Ventilation is the act of moving air. Out with the hot, in with the cool. However, we're not talking about creating a breeze. Instead, we're talking about ventilation that creates year-round benefits.
Â Â ShingleVent® II:Â ShingleVent II ridge vent installs on the peak of the roof allowing exhaust ventilation all along the roofline -- end-to-end.
This product proves that outstanding beauty and performance can be combined. Design features include an external baffle and internal weather filter for optimum airflow and weather protection. Less than an inch in height, this molded, high-impact copolymer shingle-over ridge vent permits capping of the ridge with shingles like the rest of the roof.
ShingleVentÂ® II Class A : There's two great things about Air Vent's 7-inch and 9-inch ShingleVent II Class A shingle-over ridge vents: they're fire rated for Class A roof decks and they still have the advanced design of other Air Vent ridge vents including the external baffle and internal weather filter for superior airflow performance and weather protection.
ShingleVent II Class A ridge vent installs on the peak of the roof allowing exhaust ventilation all along the roofline -- end-to-end.
Multi-Pitch FilterVent®: Multi-Pitch FilterVent ridge vent installs on the peak of the roof allowing exhaust ventilation all along the roofline -- end-to-end.
Versatile and flexible one-piece aluminum design enables Multi-Pitch FilterVent to fit roofs with 3/12 to 12/12 pitches. This ridge vent combines advanced design with simple, secure installation to provide outstanding performance.
VenturiVent Plus : The low-profile, shingle-over look of VenturiVent Plus creates a clean, uncluttered roofline. It installs on the peak of the roof allowing exhaust ventilation along the entire ridge -- end-to-end.
With a 12" width, matching shingles can be installed over the vent, allowing the vent to appear almost invisible from the ground.
FilterVent : Specialty Vents For special applications Air Vent makes specialty ridge vents: Flash FilterVent, Peak FilterVent, Tile FilterVent and Utility FilterVent. All FilterVent specialty style vents offer the same features as Multi-Pitch FilterVent, including an external baffle and our internal weather filter -- the keys to delivering exceptional performance.
Specialty vents provide 9 square inches of net free area per linear foot (Tile FilterVent provides 18 square inches per linear foot) and are available in a variety of colors.
Rolled Ridge Vent: This low-profile, shingle-over vent installs at the peak of the roof allowing exhaust ventilation along the entire ridge -- end-to-end.
Made of durable polypropylene construction, this rolled ridge vent conveniently conforms to any roof pitch.
PowerCool Roof-Mounted Powered Attic Vent : Electric-powered attic vents use a thermostat and humidistat control to monitor heat and moisture buildup inside the attic.
Featuring a low-profile dome, the power attic vent is unobtrusive when installed on the roof slanting away from the front of the house. It's an efficient option to replace wind turbines or roof pots already in place.
SolarCoolâ¢ Roof-Mounted Power Attic Vent : A smart alternative to conventional attic vents, the SolarCool Attic Vent, with its attached solar panel that tilts and rotates to maximize exposure to the sun, operates during the day and collects power from the sun to convert into electricity. In turn, this energy operates a high efficiency motor inside the power vent, so there's no added cost for electricity. That saves energy, which is better for the environment.
Solar Powered Gable-Mounted Attic Vent :The Solar Powered Gable-Mounted Attic Vent operates during the day and collects power from the sun to convert into electricity. There's no electrical hookup or electrical costs ever. It's easy to install and easy on your wallets. And that means environmentally friendly, budget conscious operation for year-round comfort.
Gable-Mounted Power Attic Vent: It's electric powered and uses a thermostat and humidistat control to help prevent heat and moisture buildup inside the attic.
Installed in the gable end of the house, the Gable-Mount Power Attic Ventilator operates 30% more quietly than comparable units and with 35% greater efficiency. What's more, since many homes already feature a gable or vent, it may not be necessary to cut a hole to install the gable-mount ventilator.
Airhawk® Roof Louvers : These covered openings allow air to escape the attic. Several of these vents are usually required to properly ventilate the attic. They should be placed evenly across the roof. Choose from metal or plastic in round, square or slant-back designs.
Wall Louvers : Wall louvers are installed in the gable end of the attic. The higher they are placed, the more effective they become as exhaust vents. Wall louvers are not preferred for ventilating an attic, because they provide limited airflow under the roof deck, resulting in "hot spots."
Airhawk® Wind Turbines : A non-electric alternative to ventilation, these vents use the natural force of wind and air pressure to spin and vent out stale attic air. They do it with a series of specially shaped vanes that catch the wind and provide rotary motion. This pulls hot, humid air from the attic. Turbine vents provide a low-cost ventilation alternative in areas where wind speeds of at least 5 mph are typical.
Continuous Soffit Vents : For intake venting, made in plastic or aluminum, these vents install in your soffit or eave areas.
Available in aluminum or PVC, these vents are 2" by 96" long and provide 9 square inches of net free area per linear foot.
Undereave Vents : These screened aluminum vents are available in three sizes: 16" x 4" provides 28 square inches of net free area per piece; 16" x 6" provides 42 square inches of net free area per piece; and 16" x 8" provides 56 square inches of net free area per piece.
