Access and daylighting
Roof hatches, skylights, and access alterations that need new framing or changed roof geometry.
Engineering Systems
Roof Curbs, Openings, and Penetrations
This page covers the structural side of roof openings: skylights, hatches, ducts, drains, curbs, vents, overflow changes, and roof-access alterations where joists, slabs, beams, or deck continuity are affected.
Why these details matter
Many roof alterations interrupt framing that was not designed to be cut casually. Even small penetrations can introduce trimmers, headers, local reinforcement, drainage conflicts, or temporary stability concerns once the actual field condition is exposed.
Asvakas helps define the building-side structural scope so roof openings are coordinated before demolition or layout reaches the field.
Typical applications
Mechanical penetrations
Ducts, vents, drains, and curb-supported equipment openings that affect deck or joist continuity.
Occupied-building coordination
Projects where existing framing differs from record drawings and the opening detail must be adjusted cleanly.
