Don’t forget the “other side” of your roof.
The interior of your roof has to be maintained and insulated. Ventilation is very important to the health of your roof from the inside out.
But what role does baffling play in the performance of your roof? First let’s discuss the process of ventilating your roof.
The gable of your building should have openings to allow fresh air to enter and stale air to exit your structure. If you fail to do that, any moisture that accumulates into the attic of your building runs the risk of becoming stagnant. As a result, you could experience the build-up of mold and mildew. To prevent this possibility, you should install vents in your rafters to allow for the movement of air.
Baffling is installed between your roof and insulation to allow for the flow of air. Baffling is often made out of foam or plastic so it’s light but provides a buffer between the roof and the insulation.
Baffling should be cut to fit precisely and should never cover any portion of the vent or soffit. It’s important to keep the opening clear so air can circulate. You’ll want to be sure to tack or staple the baffling to your roof so it stays in place.
It’s easiest to install baffling before insulation has been put in place, but it can be done after if you carefully peel the insulation away.
