Understanding Traditional Pipe Boot Materials


Before we delve into the specifics of the GAF Master Flow Pivot Pipe Boot, let's take a moment to consider the alternatives.

When it comes to roofing, the devil is in the details — or in this case, the pipe boots. Traditional pipe boot materials have their merits, but they also come with a set of drawbacks that might give you pause:

Plastic Pipe Boots with Rubber Gaskets: While your wallet might breathe a sigh of relief initially, these boots may surrender to UV rays and weather faster than you'd like.

Galvanized Pipe Boots with Rubber Gaskets: A step up in durability, yet like the plastic boots they depend on a rubber gasket which will fail sooner or later. They can also wave a white flag to corrosion.

Lead Pipe Boots: They stand their ground against the elements but at a higher cost. The issue we've seen over the years is damage from rodents. Squirrels or raccoons to be specific.

Now, let's pivot to the GAF Master Flow Pivot Pipe Boot and see how it stands out from these traditional options.

Here’s why it’s becoming a favored choice among contractors and homeowners alike:

  • All-Metal Construction: It fully encapsulates plumbing pipes, leaving no part exposed.
  • No Exposed Seals: With no seals or gaskets that degrade over time, it ensures a longer lifespan without maintenance worries.
  • Rooftop Pitch Adjustment: Its unique ball and socket feature allows for easy adjustment to fit roof pitches from 3:12 to 12:12. Making installation a breeze.

GAF Warranty

GAF guarantees the Master Flow Pivot Pipe Boot Flashing not leak for 50 years. This warranty applies when a GAF-approved contractor installs a qualifying roofing system. Compare that to 5 years or no warranty from the traditional pipe boots.
