How Do You Choose The Proper Ventilation For Your Roof In Mercer County, PA

Based on the climate, the type of roof material, and other factors, the type and amount of ventilation are two primary considerations when designing a new roof based on the climate, the type of roof material, and other factors. The proper ventilation can ensure your home stays comfortable and reduces the risk of moisture problems. The wrong kind of ventilation leads to excess moisture problems. Understanding the options and how they affect your home will help you choose the right type of ventilation for your roof in Mercer County.

Benefits of Proper Roof Ventilation

Here are some of the most significant benefits of keeping your attic properly ventilated:

Keep Your Utility Bills Down

The first step to maintaining proper ventilation is to install adequate insulation in your attic. Without insulation, heat escapes through the roof in winter and enters the home in summer. You can combat this with proper insulation and ventilation. This will keep your home warm in winter and cool in summer, saving you money on utility bills.

Increase Your Roof’s Lifespan

Proper ventilation keeps excess moisture out of your attic. As you know, water is bad for any part of your home. In an attic, excessive humidity is even more harmful because it can cause severe problems for your roof. Moisture causes rot and other damage that can significantly shorten the lifespan of your roofing materials and shingles. By keeping water out of your attic with proper ventilation, you’ll protect various parts of your roof from premature damage.

Prevent Mold and Moisture Damage

The main reason mold and mildew love to grow in your home are because they thrive in a moist environment. Over time, high humidity levels can cause costly damage to your house’s structure and contents. By ventilating your attic, crawl spaces, and basement as necessary, you can significantly lower humidity levels in these areas.

Prevent Ice Dams

Ice dams form when the snow melts on your roof and refreezes near the eaves and gutters. Because the temperature near the eaves is usually much cooler than on the rest of the roof, it causes water to back up under shingles and leak into your home. Ventilation helps keep temperatures even across your roofline to prevent this from happening.

Improves Air Quality

Excessive moisture in attics and crawl spaces can lead to fungal growth that releases spores into the air that you breathe. Ventilating these areas helps eliminate excess moisture to prevent this from happening.

Types of Roof Ventilation

There are several types of roof ventilation to consider when designing a new roof or trying to improve the ventilation of an existing roof: 

Ridge vent

Also called a peak or cap vent, one of the most efficient ways to ventilate a roof. It's installed along the apex, or top, of a roof ridge and can be covered with shingles matching those on the rest of the roof.

Soffit vent

These vents run along the eaves of a roof and allow air to flow under the roof, sheathing up into an attic space. They are often hidden behind a soffit board and can be made from vinyl, wood, aluminum, or other materials.

Box vent

This simple type of vent looks like a square box with louvers that fit over the top of an existing soffit vent. They are used when additional ventilation is needed, but there is no attic space for a ridge vent to exhaust into.

Turbine vent

This air exhaust uses wind to power its spinning action and draws air out of an attic or other space. It often looks like a miniature wind turbine mounted near the peak of a roof.

Off-ridge vent

The off-ridge or ridge vent is a common type of roof ventilation. An off-ridge vent is placed at the peak of a slanted roof and allows air to escape from the attic through the vent, which is usually covered with shingles.

Gable vent

A gable vent can be located on a home's roof, near the top. The gable vent is an opening in the wall that allows warm air to escape from an attic area through the vent. A gable vent may also allow cool air to enter the home during the summer months when windows are open and a breeze blows through the house.

Cupola vent

A cupola is a structure built on a roof that often has windows or other openings to allow airflow within the structure. The cupola can increase ventilation by allowing warm air to escape and cool air to enter an attic area located directly beneath it.

Tips on choosing the best ventilation System

Correctly sized ventilation unit.

If you choose a ventilation system that is too small for the property, it may not be able to circulate the air efficiently and not be able to work at its optimum level. On the other hand, choosing an oversized unit will result in higher energy bills.

Automatic functions of the unit

Most ventilation systems have thermostats that switch on automatically when it senses too much moisture in the air in your home or office. It also has a humidistat which detects humidity levels and switches off once it reaches normal levels.

Air circulation

The air circulating through your property should come from outside and return outside again. If this is not done correctly, you risk bringing dampness into your home or office."

Hire a professional Roofer

When buying a ventilation system, it is best to hire an experienced roofing contractor for the installation job. Roofers can recommend the best quality products according to your needs and budget. Besides, hiring a roofer will ensure the system is installed correctly and works optimally.

Plan your budget

The cost of ventilation systems varies according to their size, quality, and brand. Usually, high-quality products from renowned manufacturers cost more than cheap ones from local manufacturers. Make sure you have planned a proper budget before starting your search for ventilators; this will help you narrow down your options quickly and make an informed choice.


It is essential to look for a roofing ventilation system with a warranty. This assures you that if anything does not work correctly, it will be fixed by the company or person who sold you the product. This ensures that you don't incur any additional costs when fixing simple problems with the ventilation system.
