Hello everyone,

I am new to this forum so please excuse me if I have posted this in the incorrect location. I have recently installed my woodstove in a new location in my house and have installed the pipe through the roof. Whenever it rains I get the tiniest drip of water coming down into my house. I have attached a picture for reference. There is no water in the ceiling box as I have checked this numerous times. There is no water coming down the inside of the piping either. The water seems to be trickling down the exterior stainless steel pipe and then dripping onto my stove. I have sealed thoroughly where the pipe goes through the rubber boot on my metal roof. I am perplexed. The only thing I could possibly think of is that water is somehow getting between the seams on the stainless steel pipes. Should those 36 inch seams be sealed with high temperature sealant? Or could it be a rain cap issue?

Any help is appreciated!

Thank you,

The pipe is vertical, all the way? Can you post a pic of where the chimney goes through the roof? Cap? etc. If the exterior chimney is installed correctly it's pretty impossible for water to get into the inside of the pipe. From your pic, it's from the outside your pipe. Mine has leaked occasionally from where the chimney passes through the roof flashing, around the pipe. I just resealed it and it was good.
 
Yes. The pipe is vertical all the way. I don't have any great pictures on me right now. I can get some when I get home tonight. I am attaching a picture of the boot. I have a storm collar that I will be installing this weekend as I thought that may be the issue.

Recheck where the rubber meets the metal roof. Chances are the water is coming in between the ridges on the flat sections of the metal.

I had pulled my chimney early in the summer and stuffed an upside down plant pot in the chimney hole so I was able to stick my head up thru where the chimney once was and see the water coming in on the flat section between the ridges. I cleaned off all the caulk and roofing tar that was around the perimeter of the rubber boot and applied a small bead of roofing tar around the boot base and only as high as the thickness of the base, about 1/8”.

Worst part of the job was cleaning up the old caulk and roofing tar, Varsol and a bunch of rags worked after the excess was scraped off.
