Ventilation

Your home’s roof relies on proper ventilation.

Ventilation is the process of supplying a continuous supply of air through the attic space. Proper ventilation consists of 50% intake under the eaves and 50% exhaust near or at the roof peak.

The process of installing proper ventilation and maintaining this balance is very difficult to achieve, so hiring a professional ventilation contractor such as Mid-Cities Roofing Contractors, Inc. is imperative. By ventilating your home, you’re preserving all of its components, including the longevity of your roof.

Why Should You Ventilate Your Home?

To combat heat and moisture, you must ventilate your home year round. Heat in unventilated attics may cause temperatures to exceed 150 degrees, causing damage to shingles, roof sheathing and possibly radiating heat to the living area. Moisture is the number one enemy, causing rot, mildew, mold, paint blisters and renders insulation to be ineffective. Proper ventilation reduces energy bills, winter ice buildup and eliminates mold and mildew, which can lead to major health problems. By ventilating, you are extending the life of your roof’s shingles, insulation and other building components.

Ventilation Tips

Lack of Under Eave Soffit Ventilation – This is the #1 reason for weather infiltration. There should be an equal or slightly greater amount of free area in the soffit, regardless of the type of exhaust system used. Make sure that the soffit vents are not covered by insulation; the light should be visible in the soffit area.

Mixing Exhaust Products – Do not mix different exhaust products in a single attic, meaning do not use roof vents with ridge vents, ridge vents with power vents, turbines with roof vents, etc. Avoid using ridge vents or roof vents near gable vents. Depending on wind direction, the gable vents can act as exhaust vents and cause the ridge or roof vents to act as intake vents. If problems occur, make the gable vents non-functional. Do not use ridge vents on rakes or hips of hip roof designs. Ridge vents are designed to be exhaust vents. When installed on the rakes, the exhaust/intake systems are indefinable.

Roof Vent Location – Keep roof vents on the same side of the ridge. Do not place them across the ridge from one another. Depending on the wind conditions, one roof vent may try to feed from the other roof vent.

FAQ

Here you’ll find a compilation of the most frequently asked questions. If there’s something you want to know which isn’t here, please send an email to [email protected]!

What's the main purpose of roof ventilation?

Roof ventilation helps regulate temperature and moisture levels in the attic, preventing heat buildup in the summer and moisture-related issues like mold and rot. Proper ventilation extends the life of roofing materials and improves energy efficiency.

How much does it typically cost to install a roof vent?

The cost of installing a roof vent usually ranges from $300 to $600 per vent, including labor and materials. The total cost depends on the number and type of vents needed for adequate ventilation.

What are the four main types of roof vents for attic ventilation

The four main types of roof vents for attic ventilation are ridge vents, soffit vents, gable vents, and turbine vents. Each type offers different benefits, and the best choice often depends on the roof’s design and ventilation needs.

What’s the most effective type of roof ventilation?

Ridge vents are often considered the most effective because they provide consistent, natural airflow across the entire roofline. However, combining ridge vents with soffit vents offers optimal ventilation by allowing cool air to enter from the soffits and exit through the ridge vents.

Does a hot roof need ventilation?

Yes, a hot roof (one without an attic space) still needs ventilation to prevent overheating and moisture buildup, which can damage roofing materials and reduce energy efficiency.

Does a cold flat roof need ventilation?

Cold flat roofs benefit from ventilation to prevent moisture accumulation, which can lead to mold growth and damage to insulation and structural elements. Proper ventilation helps maintain a dry, healthy roofing environment.

Do metal roofs need ventilation?

Yes, metal roofs require ventilation to manage heat and moisture. Adequate ventilation prevents condensation from forming, which can cause rust and other moisture-related problems, ultimately extending the roof’s life.

Do slate roofs need ventilation?

Slate roofs also benefit from proper ventilation, as it helps regulate attic temperatures and prevents moisture buildup. Proper ventilation ensures the slate remains in good condition and maximizes the roof’s lifespan.
