Recap of Roof (SHHGR342)- 12 Wing Shearwater

The Department of National Defence (DND) is proposing to recap the roof at building SHHGR342, 12 Wing Shearwater. During a wind event, the upper membrane layers of the roof delaminated from the insulation and are loose and failing. Project activities will include removal of concrete paver stones on existing roof system; removal and disposal of 2-ply modified bitumen roofing and overlayment boards; removal and replacement of wet insulation; and new 75-millimetre insulation, cover board, and 2-ply modified bitumen roof over the area of work. The lighting protection system will also be removed, reinstated, and re-certified.

Latest update

April 17, 2023— The Department of National Defence issued its Notice of Determination and determined that the project is not likely to cause significant adverse environmental effects.
