Skylights and other obstacles

Proper attic ventilation use to be difficult to achieve where skylights and other obstacles impeded the airflow from the soffit to the ridge. This is where cross-ventilation is required to allow the blocked air to travel around the obstacle. RafterVent allows all the intake to be connected continuously with the exhaust vent.

Obstacles blocking the airflow can allow moisture to build in the unventilated area. This can impact the life of the roof. Preparations for how to ventilate around your new skylight is a critical portion of your project. Take a few minutes to install Raftervent and you could add years to the life of your roof.

What exactly is RafterVent?

RafterVent is an under-plywood, top-of-rafter vent easily installed during the construction of an addition or a new home. The RafterVent provides adequate ventilation in the spaces to either side of the vent placement.

It is a required vent product when your soffit to ridge air flow is blocked by a skylight or dormer. RafterVent easily allows air movement in those trapped areas.

It eliminates the need to drill holes in the rafters to ventilate areas trapped by construction supports. Use it in areas otherwise unventilated and considered problem areas. It is very versatile and can be used on wall surfaces between siding and wall sheathing, allowing air to move between those areas.

RafterVent can also help stop mold and mildew when installed properly.
