Installing Leak Barriers – Sealing in Plumbing Vents


To divert any leak water out of the system over the roof deck protection using Weather Watch or Storm Guard at plumbing vents or soil stacks. First install the Ice and water shield layer in an under and over placement as the residential steep slope roofing is a water shedding product not a water proofing product, Shingle-Mate or Deck Armor roof deck protection to within 6″ of the roof vent pipe. The Weather Watch or Storm Guard needs to be fully adhered to the roof plywood, OSB, or planking and should be fully adhered to the succeeded courses of shingles to properly expel the water to the roof below.

Take the picture you see on the internet with a grain of salt as they are not accurate to real world practices of the way a shingle should be installed with ice and water shield. With standard strip shingles you need to install a diapered shingle to prevent water from entering the water groove or water eye.

Cut a 20″ minimum square piece of Weather Watch or Storm Guard leak protection underlayment then place this piece over the center of the pipe top. Cut an X from one edge of the pipe to the other, cutting this X slightly smaller than the pipe width will allow a full seal around the entire roof vent pipe.

Remove the split-back film and lower the Leak Barrier around the pipe, be sure to press the membrane firmly to seal it to the deck, to the roof deck protection, and up the roof vent pipes sides.

For Advanced Installation Method: To divert any water out over the roof shingles for laminated shingles only this method cannot be used with three-tab shingles, install Shingle-Mate or Deck Armor roof deck protection around the pipe.

Cut Weather-Watch or Storm Guard leak barrier 20″ minimum wide to surround pipes, shingle up to the vent pipe, cutting the top of the shingle around the pipe, firmly press Leak Barrier over the top half of the shingle in front of the vent pipe then seal Leak Barrier to Shingle-Mate or Deck Armor roof deck protection and decking above the vent pipe, finally cover roof deck protection and leak barrier with shingle set in plastic cement.

It is very important to have a Weather Stopper Golden Pledge when installing a Weather Watch or a Storm Guard Leak Barrier around your homes plumbing vents. This is required on all Weather Stopper Golden Pledge installations and also when installed or used on Weather Stopper System Plus Installations.
