Absolutely it will work. You are describing what is known as the “saw-toothing”, which means the panels are staggered (mostly a ridge condition) in order to keep the panels at the eave straight. There are several potential “causes” of this condition but will not address them here. The waterproofing foam in the Vent-A-Roof products is 12mm wide.
If the saw tooting is worse than 6mm, we recommend “popping” a chalk line, to make the panels realign and use a power tool to make the correction. Keep in mind that to make a weather-tight seal, the panel needs to embed in the foam a minimum of 3mm. Vent-A-Roof does have a little “play” allowing you to push and pull the vent section to conform to slightly “out of square” ridge conditions.
It is vitally important that Hip cuts are very straight, this will make intersections easier to negotiate.
