6- Now, you can add additional chimney sections. Continue adding chimney lengths until a height of about 2 fet below the next ceiling level. An attic insulation shield must be installed where a chimney passes from a lower living space into an upper living space or attic space. It is designed to keep insulation materials away from the chimney. A second attic insulation shield must be installed if your chimney passes from a lower living space into an upper living space. As wee, you must enclose all sections of the chimney where is passes through a living space. Elbows (15o or 30o) are used when you need to offset your chimney to clear an obstruction or to avoid having to cut joists.
7- Once you have cut through your roof and framed the joists, it is time to work outdoors. Authorities require that the chimney extend not less than 3 feet above the highest point where it passes through the roof of a building and not less that 2 feet above any portion of the building within 10 feet. You will need to install a roof flashing. The roof flashing slides over your chimney pipe and goes under your shingles. Once you have done that, check that everything is plumb, and nail the flashing into the roof deck. Seal the joint between the shingles and the plate with silicone.
