Air vent Pipe U joint in attic leaking
Comments (2)Plumbing vents are rarely if ever sheltered. The vent section of the plumbing stack is just as water tight as the waste part, or it's supposed to be. What is this,"U" joint you're speaking about? Is this a trap? Posting a picture would help. Ron...See MoreRoof vent leak
Comments (10)Sealant/caulk is commonly misused. It cannot seal anything if it doesn't fit between two relatively stable clean surfaces that don't move more than the material can stretch and still adhere. On the surface of another material it will simply become hard from UV exposure and crack. That goes for all sealant/caulks. They don't last forever even when installed properly in a joint. When I first learned to detail building joints in the 60's, sealants and adhesives were not relied upon for weatherproofing. Everything had to shed water with a mechanically sound detail. That approach has been abandoned in favor of easy fixes that need frequent maintenance and many building owners have suffered losses because of it. Any time you are tempted to use a sealant/caulk you should first consider a more permanent solution. In '71 our spec writer told us to stop using the word "caulk" and only use "sealant". In general, sealants are designed to seal a joint between materials that can move and caulks are designed to fill a stationary gap. I had to change the word caulk to sealant on a very large set of drawings and consequently avoid the word caulk unless it is part of a trade name. In your case a stainless steel storm collar or a tight fitting neoprene gasket (preferably with a stainless steel compression band) are the only flashing details that will be permanent. That's assuming the base flashing cone has not split at the roof line seam. All flashing should have a "base flashing" and a "counter flashing". In this case the base is a cone in a "witch's hat" shape, interleaved in the shingles and the "counter flashing" is the storm collar. Don't be tempted to use an "all-in-one" half metal and half neoprene "boot"....See MoreRoof Leak, Possibly from Bathroom Vent
Comments (4)I'm not a fan of roofing cement but it's nessary on exposed nail heads. The needles might very well deflect water enough to cause it going beneath shingles....See MoreLeaky New Roof Roofer faults vent pipe.
Comments (15)Thank you all for replying. I can't figure out how I got along 24 years with the old roof, without a problem. and now I have a leak. If there were water in the pipe, I would think it would be contained in the pipe, and not leak onto the ceiling below. My vent/flashing looks like ksc36's photo, except that the bottom underneath the pipe has some shingles covering it.Should there be? I'm not a roofer, but shingles on the lower part of the flashing could create a "well", no? I thought that a proper installation is similar to what ksc36 has in his picture. The roofer surmises that, because my neighbors had a sagging pipe, I do also. (My home was built on site, theirs was modular, trucked in.) As far as getting a picture, the roofer said a few days ago that he would take a picture, but never did. He wants to "give me an estimate" of what it would cost to cut an access opening in the ceiling. I'm the guy who framed the third floor, wired it, insulated it, and painted it. (Only job I farmed out was for the rockers). Building inspector said, via telephone, that he could stop by and offer suggestions....See MoreDon Dunnuck
