How to determine ventilation requirements according to the type of roof?

Manufacturers have specific factors that they measure to provide the best diagnosis based on the type of roof, as in the case of a rooftop terrace or green roof. These factors are, for example, the spacing available in the attic, the number of square feet of insulated ceiling, and the configuration of the attic. For more information, see our technical consultants. They will inform you on the ventilation requirements for your type of roof.

How to ventilate the house if it does not have enough air space?

You can modify the structure to create an air vacuum which promotes better circulation in the attic. Otherwise, you can simply replace the existing insulation by using an insulator with a high R-value, such as polyurethane. This solution will significantly increase the resistance of the insulation in the attic.
