What happens here

Install the sub-fascia board along the ends of the rafters. Ensure the sub-fascia is installed at the correct height relative to the top edge of the rafters. If the sub-fascia is too low, the roof decking will not sit properly or might create a hump. If it's too high, it will hold the decking up, creating a gap or an uneven surface. After the sub-fascia is correctly installed, install the roof decking (OSB or plywood) over the rafters. To prevent roof uplift in high winds, use hurricane ties or other approved fasteners to securely attach rafters or trusses to the top plates. Failure to install these critical connections can lead to the roof detaching from the house during extreme weather.

Goal: Complete the roof structure and secure it against uplift forces.

What they say

Hide

your subfascia is too high, it'll hold it up. Install your roof decking. Hurricane ties or other fasteners attach your rafters or trusses to your top plate. If one of these doesn't get installed and you get uplift, so if you don't make the proper connection, then your structure can fail. Thanks for watching.
