5.7.6 INSTALLING FLASHING AND STORM COLLAR
Remove nails from the shingles above and to the sides of the chim- ney. Place the flashing over the vent pipe and slide it underneath the sides and upper edge of the shingles. Ensure that the vent pipe is properly centered within the flashing, giving a 3/4" margin all around. Fasten to the roof on the top and sides.
Do not nail through the lower portion of the flashing. Make weather- tight by sealing with caulking. Where possible, cover the sides and top edges of the flashing with roofing material.
Apply waterproof caulking around the vent, 1" above the top of the flashing and push the storm collar down into the caulking. Attach a rain cap to the top of the last vent section.
