Membrane, Vinyl & Panel (MVP) Gauge


PRE-ORDER ONLY – Expect delivery December 2021
Bullybag Membrane Vinyl & Panel Gauge measures membrane roofing, vinyl siding & metal panels.

Available on backorder


The Bullybag Membrane, Vinyl & Panel Gauge uses the published industry standards as well as those pertinent to estimating programs to determine the measurable differences of roofing membranes, vinyl siding, and metal panels for roofing and siding. The Bullybag Membrane Vinyl & Panel GaugeTM will help you suggest replacement roofing membranes and roof panels, with more accuracy. It may be used to estimate the thickness of both steel and aluminum panels, single-ply membranes and vinyl siding grades.

For Single Ply Roofing Membrane: All single-ply membranes (excluding modified bitumen, self-adhering, and fleece-backed)
For Vinyl Siding: Determine the grade of siding to suggest
For Steel Panels: Uncoated or coated, galvanized or Galvalume® (with or without additional coating)
For Aluminum Panels: Uncoated and anodized panels

The Rare Earth Magnet on the MVP Gauge helps you differentiate and document panel types from each other.
In general, if the panel is made of steel, the magnet will typically react and the magnet will attach.  (Some stainless steels also are not magnetic and will not react.)
If the panel is made of aluminum, the magnet will NOT react and will not attract to the metal.

EASY To Use… Follow these easy steps to estimate:
1. Identify the type of material you are inspecting.
(Best to start by using the magnet to help you determine if you are gauging aluminum or steel.)

2. Start with the widest slot and hold the gauge loosely in one hand, drag the slot of the determined material along the edge of the membrane, vinyl or panel. Do not force the gauge onto the material, keeping note that even a slight burr (rough edge on the material post cut) may misrepresent the gauge of the material.

3. When dragging the tool, the slightest resistance constitutes a difference in gauge whereas the slot larger is typically the estimated panel thickness.

4. Best practice is to take multiple measurements and document all of findings.
