Roofs and Attic Ventilation Products available to hire wexford roofing

There are numerous types of attic and roof vent products that you can choose from for your home. They are commonly described as:


  • Roof vents

  • Attic fans

  • Gable vents

  • Louvers

Products for roof and attic ventilation can be classified into one of two categories:


  • Intake air ventilation

  • Exhaust ventilation, or

  • Both intake and exhaust

  • Why do I need exhaust and intake vents in my attic?

  • Every attic ventilation plan should consist of a combination intake as well as exhaust vents.


Attic fans and roof vents operate all year round to:


  • Warm, moist air should be taken away

  • Reduce condensation

  • Keep your attic dry

Let heated and pressurized air go out, so it won't attempt to enter areas that are conditioned.

The most crucial factor to ensure optimal ventilation is having the correct amount of both kinds. If you only have one type of venting, or an uneven amount of one type of venting can lead to issues with pressure.

It's in the attic, but you don't care?

Your attic can be exposed to one or all of the decking depending on your architectural design and roof.


Many people consider attics as not conditioned storage spaces. This is certainly the case for certain homes, especially those with frames made of rafter. However, many "attics" are simply spaces between the roof deck and the ceiling. Big or small the spaces require venting to manage heat and moisture within the structure.


If you do not balance the amount of exhaust roof ventilation and intake roof ventilation, water could build up in the attic. This could cause many problems including:


  • Mold

  • Mildew

  • The structural quality of your roof

Ask the roofing company near me about how to ventilate the area that is above the cathedral ceiling or in other small attic space.


Ventilators for intake

The name suggests intake vents are designed to take in air from the outside. This air is then brought into the attic in order to replace the air coming from the exhaust vents. They aid in maintaining a healthy airflow.


Vents for intake are generally located beneath the eaves of the roof. These vents help to reduce energy costs and aid in venting the exhaust of the attic more efficiently.


There are two types: roof-mounted intake vents and vents in the soffit.


Soffit Vents

Soffit vents are typically located in intake roof vents. They're found under your roof's eaves, along the length of your home or in between the joists.


Pro Tip: If you have installed insulation that has been blown in, ensure that it doesn't block the flow of air to the vents in the soffit.


Roof Vents

An intake vent on the roof is an option to consider in the event that your house does not have a soffit or exposed rafters below the eaves.

Exhaust Vents

Exhaust vents let air flow out of the attic and out to the outside. Attic vents and ridge vents are two examples of exhaust vents. these are typically placed higher on the roof. They are typically placed on the topmost pitch, in the area where hot air tends gather. Steadfast roofing can help you to achieve this.
