What type of pipes penetrate a roof?

  • Vents
  • Electrical masts
  • Utility/ sewer pipes
  • Attic fans
  • Off-ridge vents
  • skylights

How do you seal up these penetrations?

  • Boots– made to be cut to fit varying sizes, which range from ¾” all the way to 18” depending on the radial dimension of the pipe.

Also known as:

  • Roof jack
  • Witch’s hat
  • Madonna cone
  • Weather head
  • Goosenecks– Used for attic ventilation OR to cover an exhaust pipe through a roof
  • Dek Strip– like pipe boots, this material is a flexible neoprene product that is completely chemical resistant

Why should we seal such penetrations?

Since each protrusion in the roof is coming from inside of the house/ attic space, anything backing up beneath can be detrimental to your home. This includes water, debris, rain, bugs, and even rodents. Sealing up these openings prevents the invasion of anything that doesn’t belong!!!
