How Far Should A C Pipe Be From Roof

Thanks for the suggestions.

How far should a c pipe be from roof. Purlins are 2 by 4 feet and are installed much like metal roofing. They give added support to the roof and also provide a nailing surface for the end panels and drip edge. Roof pitch is easily calculated and if you don t know how read my article understanding and calculating roof pitch. They are installed on top of the roof rafters with a felt underlayment or vapor barrier installed on top.

The vent opening must be far enough above the roof and away from doors and windows to prevent the sewer gases from drifting into the house. 8 12 minimum chimney height. I guess then from what i ve read here the vent should be minimum of 600mm high. Obviously look to take out the palm trees to the west as well.

Metal roof purlins are installed horizontally under metal roofs. My understanding is that the chimney should be at least 2 feet higher than any part of the roof within 10 feet of the chimney. If the pipe is farther than 10 feet from the roof. In your situation the minimum height of your chimney above the eaves should be the following depending on your roof pitch.

6 12 minimum chimney height. Does anyone know what legal height requirements there are for vent pipes or as long as it sticks out of the roof its all sweet. In canada the national plumbing code requires that the minimum trap arm be at least 2 times the pipe diameter e g 1 25 inch pipe needs a 2 5 inch trap arm 1 5 pipe needs a 3 inch trap arm etc and that the vent pipe be one size larger than the drain that it serves also a cleanout is required on both the vent and the drain. 6 minimum or 6 higher than snow accumulation for the geographic area.

I figured i could shorten the vent pipe and maybe leave a panel out directly south of the pipe and enough room on the sides so the shadow does not hit any of the panels. Additionally the vent runs up the wall just outside the back door so the vent is also within 3m of the door. The code requires a 10 foot horizontal distance from any. Open vent pipes that extend through a roof shall be terminated at least 6 inches 152 mm above the roof or 6 inches 152 mm above the anticipated snow accumulation whichever is greater except that where a roof is to be used for any purpose other than weather protection the vent extension shall.

I didn t know it was relevant but the vent is exiting the roof just about 400 mm from a gutter.
