� Nguyen Residence Tree Damag�essment <br />CG Project No. 16119.10 <br />5. Additional Plvwood Sheathin� <br />iMay 2, 2016 <br />Page 2 of 6 <br />There are two existing layers of asphalt shingles that are being removed and replaced with a single layer <br />of asphalt shingles over the entire roof. A new layer of 7/16" plywood sheathing will be placed over the <br />existing skip-sheathing as a base for the new asphalt shingles. This will actually reduce the dead loads <br />on the roof framing. Therefore, the undamaged roof framing may remain in place without further <br />analysis (per IBC Section 3403.3). <br />Attachments <br />Photos pp. 3-6 <br />Structural Repair Plan SK-1 <br />Structural Repair Details SK-2 <br />DISCLAIMER <br />This observation is the professional opinion of CG Engineering PLLC based on the information available during this assessment or evaluation.
