Should Roof Sheathing be Flush with Fascia?

Both residential commercial roofing carries various components, each of which plays an important role in guaranteeing structural integrity and weather protection. Roof sheathing and fascia are two of these features, both essential components of a well-designed roof. But one common concern is, ‘Should roof sheathing be flush with fascia?’.

Let’s find out if roof sheathing and fascia be level with each other.

The Function of Roof Sheathing

Roof sheathing, commonly comprises of plywood or oriented strand board (OSB), acts as the roof’s foundation or decking. It offers a strong foundation for attaching roofing materials such as shingles or tiles.

Roof sheathing, in addition to structural support, contributes to the overall stability of the roof by distributing the weight equally throughout the roof’s framework.

The Importance of Fascia

Fascia is the vertical finishing edge that runs around the roof’s perimeter. It is both useful and aesthetically pleasing. Fascia protects the roof’s edges and the building’s inside from water damage by directing rain away from the structure. It helps the roofline’s overall design, offering a clean, completed aspect.

Should Roof Sheathing be Flush with Fascia?

Roof sheathing was commonly extended slightly past the fascia board in ancient roofing procedures. This overhang kept water from trickling down the fascia and potentially damaging it.

On the other hand, modern roofing systems sometimes entail the installation of drip edges or flashing, which deflect water away from the fascia, even if the sheathing is flush with it.

Depending on the design and ventilation system in place, the sheathing flush with or slightly protruding past the fascia might affect airflow in the attic space.
