Thank you both for the replies. I think venting out the side of the house is probably the best option. | ||

Chris, Warren doesn't care if the metals are "Catholic" !!! Sorry, I had to write that out. Seriously, I would have him consider replacing the old units with high efficiency ones and venting them right out the side of the house, and then eliminate the pipes all together. It makes a lot more sense, and since he is spending the money for the expensive tile roof, I am sure taht the extra money wouldn't be that big a deal. To cut the pipes off and tie them into a low profile roof vent would be to invite trouble. The would probably react with the exixting metal of the pipes too in a "Cathodic" way. One will eat the other and that is not a good thing. Hang in there guy. That is more information that I wanted to know too. | ||

I am in the process of a re-roof. We are installing a new Ludowici Ludoshake roof and replacing all flashings with new 16 oz. copper. I am wanting to replace the old galvanized parts of two water heater vents and one furnace vent. If I were to remove the cap, base, and collar, and then cut the double wall piping down closer to the roof level, could I then install a low profile copper box roof vent over the pipe. Would this affect the functionality of the vents? I know there is the option of replacing just the base with a copper flange, but my customer likes the looks of the low profile box vents. Any suggestions would be greatly appreciated. Thanks, Chris |
