Opening to roof from attic.

The rough framed opening. The 2012 international residential code requires an attic access opening for attics with an area greater than 30 square feet and a vertical height in excess of 30 inches. Your actual living space is sealed. When the attic becomes part of the home to be heated and cooled open wall gable vents and roof vents are no longer feasible but the underside of the roof the sheathing and rafters can still.

A roofer will from the attic mark a spot near the ridge of the roof he may first use nails from the attic to mark preferred spots between two rafters. The nails will show where the joists lie in the attic. Use long nails to nail an outline next to joists where ceiling material will need to be cut away. If the attic space is going to be conditioned either for living or mechanical purposes or if a home design calls for a vaulted ceiling provision r806 3 in the international residential code calls for the roof deck above the space to be vented continuously from the eave to the ridge.

From the roof the roofer will cut away shingles and underlayment and use a saber saw to cut a hole the same size as the diameter of the vent. Don t avoid ventilating your attic for fear you re letting cold air into the house.
