Guidance for small openings in deck can be found in the “Deck Damage and Penetrations” White Paper or in the MOC (Manual of Construction).If the holes are small enough, only patching may be required.  For larger openings and depending on the extent of the opening, channels or plates may be used to transfer the load to undamaged flutes.  Additional framing may be required.  Reinforcing channels or zees may be used to transfer loads from removed sections of roof for Sump Pan openings.
