Standard M-Vent™

Standard M-Vent

Why M-Weld™ Pre-Flashed Accessories?

Conventional field-built penetration flashings are among the most notorious leak sites on the roof. But, M-Weld™ Pre-Flashed Accessories offer consistent, factory-built quality every time, reducing the possibility of leaks and callbacks. M-Weld™ Accessories work with torch, hot bitumen, or cold adhesive applied systems. 

Choosing uniform, pre-flashed accessories over field-built solutions results in a neater finished appearance and can lower installation costs by up to 6%! Available in a wide variety of standard styles and sizes, plus custom-fabricated styles to meet specific job requirements. The standard M-Vent™ can help waterproof many different sizes of vent pipes and other roofing protrusions. It fits many different pipe sizes and vent stacks and repairs faulty flashing around penetrations.


  • Consistent Quality:  Factory assembly allows for a high degree of quality control over all roof flashing
  • Versatile:  Stress cracks are eliminated because it attaches to the field membrane, not to the pipe, allowing for pipe movement and expansion/contraction of membrane
  • Aesthetically Pleasing:  Offers consistent, neat appearance on all penetrations.
