Master Flash Universal Flashing

Introducing Aztec Washer Master Flash Universal Flashing

Now from Aztec Master Flash comes a roof pipe flashing solution which streamlines the task of sealing roof penetrations and makes it an efficient, cost effective and manageable for both roofing professionals or homeowners who want to do-it-yourself. An efficient and well made roof is intended to be an impenetrable barrier perfectly designed to keep heat, cold and wet out of the inside of buildings. The roof’s job would be done effortlessly if it weren’t for the fact that it is often necessary to penetrate the roofing surface with various kinds of vents, pipes or other objects. Building designers know, however, that they must supply for ways to vent gases out and to allow other things through the roof barrier, like water, gas or electrical. This is where many times weather is able to breach the barrier provided by the roof surface and damage the building interiors with unwished-for moisture. Therefore to keep the roof’s function of sealing and protecting the building interior from extraneous weather, these penetration must be sealed in some manner.

Until Aztec Washer came up with these EPDM or Silicone vent pipe flashing products the only way to seal a leaking or new roof penetration was to have a custom fabricated metal flashing created and installed. Historically, custom fabricated metal flashings were manufactured to address the roof penetration. This was not easily accomplished. Someone who was qualified to do so would need to safely climb up on the roof to take accurate measurements and account for angles and pitch.

As you can easily imagine, these holes in the roof were made in random dimensions, utilizing whatever type of cutting instrument was available. These dimensions would then be taken back to a metal fabricating shop and the custom fabricated pipe flashing was made. Then another trip up on the roof was needed to put in the metal pipe flashing. This same custom flashing occasionally did not fit as intended, creating a “Rube Goldberg” installation or the need for another flashing unit to be manufactured.

Aztec Washer’s new roof vent pipe flashing, called the Master Flash Universal Flashing, is the industry standard for traditional roof pipe flashings for those who prefer to install the round style pipe boot. The Universal Master Flash pipe boot flashing has been engineered and designed to increase the flexibility of the sleave to absorb vibration and pipe movement because the roof and the pipes expands and contracts, while sealing out undesirable elements. The Master Flash Universal Flashing roof pipe flashing design allows for hassle free on-site modification and can fit virtually all installations.


The Master Flash Universal vent pipe flashing has proven to excel in virtually any setting and delivers consistent performance from ease of installation to leak resistance under a mixture of environmental conditions. It can be relied upon to deliver superior results when used with most roofing designs and materials.


Flashings are made of EPDM and Silicone, and are designed for maximal resistance to all weather conditions. These scientifically formulated materials resist heat, moisture and sun damage for years of superior performance and effective leak resistance.


Pipe diameters can be seen clearly for proper fitting. There is no longer any need for guess work when installing a roof pipe or vent flashing. Accurate measurements are molded into the EPDM or Silicone pipe flashing for ease of trimming for a perfect fit for every installation.


The Master Flash Universal flashing base will easily mold to fit most panel configurations and roof pitches regardless of pipe location. Flexibility is achieved by a malleable metal strip attached to the EPDM or Silicone material that allows for ease of shaping so that the flashing base molds exactly to the irregularities of the roof panels for superior sealing and resilience.


This universal flashing has been designed to fit virtually all panel configurations. Normal expansion and contraction causes no problems because the unique design of this Universal Master Flash pipe flashing is flexible enough to absorb vibration and pipe movement. Easy on-site customization can accommodate all normal installations.
