Installing Flue Pipe Through Roof

Make sure to put a bead of silicone around the storm collar where it meets the chimney pipe.

Installing flue pipe through roof.

This should be done before installing the roofing material as well. All chimneys must extend 3 feet above the roof surface and 2 feet higher than any part of the building within 10 feet. Cut a framing hole at least 10 inches in diameter with a jigsaw tool. The chimney must extend at least 3 feet above the highest point where it passes through the roof and be at least 2 foot higher than any part of the building within a horizontal distance of 10 feet figure 2.

The chimney pipe must protrude through the roof a minimum of 2 feet and it must be at least 10 feet away from the roof line. Minimum clearance from combustible material. The minimum clearance may be reduced by 50 percent to 225 mm 9 in if suitable shielding is installed either on the pipe or on the combustible surface. Wood stove pipe flashing is incredibly important to protect both your stove and your roof.

When installing a wood stove at home it s important to think about the chimney. Check the area where you will install the flue pipe. The flashing can be installed quickly and easily with kits that use rubber pipe boots. Determine the number of chimney pipe lengths required.

The termination cap is installed above this point. Nail the flashing in place right after you put down the tar paper or weather membrane. The insulated chimney pipe is stacked until it reaches the required height. The rubber boot is trimmed to fit around the pipe and then secured to the roof with screws and sealant.

Safe and efficient chimney installation depends on the materials of your roof. While you re still on the roof attach the storm collar to the chimney pipe. Chimney pipes on metal roofs must be flashed in order to create a watertight seal around the pipe and prevent leaks through the roof. Pull away insulation or install an insulation shield to keep the area clear around the pipe.

When passing through the roof you need to use a flashing that matches the roof pitch. You should weatherproof the roof opening with an insulated storm collar and roof flashing. 450 mm 18 in.
