Plumbing pipe flashing types.

Plumbing pipe flashing types.

Roofing pipe flashings are used to waterproof the area around pipes or vent penetrations through the roof. There are several types of roofing pipe flashings available, each having its on pros and cons. Here are some common types:

All Steel Pipe Flashing (pre finished paint) from GAF

26g Metal GAF Pivot Boot

The Master Flow Pivot Pipe Boot Flashing’s durable, all-metal design helps provide tough protection at a notorious source for leaks on roofs – plumbing pipe penetrations. With no seals, gaskets, or collars that can degrade and leak when exposed to the elements, you can enjoy a neat, streamlined look on your new/existing roof.

From Dustin Stubbs: Squirrels will not be able to chew on these pipe boots as they are 26g steel and fully encapsulate the PVC pipe!

Lead Pipe Flashings

A lead pipe flashing is a type of roofing material designed to create a watertight seal around pipes that penetrate the roof. It is made from lead, a highly malleable and durable metal known for its resistance to corrosion and longevity. Lead pipe flashings are commonly used in roofing applications to prevent water intrusion around plumbing vent pipes, exhaust vents, or other protrusions.

Lead will last pretty much forever. The downside is that squirrels love to chew on these pipe boots.

Rubber Pipe Flashings

Rubber Pipe Flashing

A rubber pipe flashing is a type of roofing material designed to provide a waterproof seal around pipes and other penetrations through the roof. It is commonly used to prevent water from entering the roof structure around plumbing vent pipes, exhaust vents, or other protrusions.

These are the lowest cost pipe flashing’s available and usually have a life cycle of around 10-15 years in our area. We prefer using a higher quality longer lasting pipe flashing for our roofing replacement jobs. However, these are an excellent choice for roofing service projects.

Which pipe flashing will you choose on your next roof?

  1. Pipe Boots: These are one of the most common types of pipe flashings. They are typically made of rubber or thermoplastic materials and come in various sizes to fit different pipe diameters. Pipe boots have a flexible base that seals around the pipe and a flange that is attached to the roof.
  2. Cone Flashings: Cone flashings, also known as multi-size flashings, consist of a conical shape that can be trimmed to fit different pipe sizes. They are adjustable and versatile, making them suitable for various pipe diameters.
  3. Vent Collars: Vent collars are designed for use around vent pipes. They usually consist of a metal collar that fits around the pipe and a flexible or rubber boot that seals against the roof. Vent collars are suitable for different pipe sizes.
  4. Pitch Pans: Pitch pans are often used for irregularly shaped or large penetrations. They are metal pans filled with a compatible sealant and placed around the pipe penetration. The sealant is used to create a waterproof barrier.
  5. Split Flashings: Split flashings are designed to be installed around existing pipes without the need to disconnect the pipe. They have a split design that allows them to be wrapped around the pipe and then sealed, making them suitable for retrofitting.
  6. Lead Flashings: Lead flashings are durable and malleable, making them suitable for various pipe sizes and shapes. They are often used for long-term weatherproofing and are resistant to corrosion.
  7. Collar Flashings: Collar flashings are metal flashings that fit around the base of a pipe. They often have a cylindrical shape and are secured to the roof to provide a watertight seal.
  8. Solar Panel Flashings: Specifically designed for solar panel installations, these flashings accommodate the penetrations associated with solar mounting systems.

When selecting a roofing pipe flashing, it’s important to choose one that is appropriate for the type of roof material, the size of the pipe, and the specific conditions of the installation site. Proper installation is crucial to ensuring a watertight seal and preventing leaks.
