Our FlexPro Profile Venting Material vents, protects and lasts like no other. While polyurethane products constantly expand (as they soak up water) and contract (as they dry out), causing them to disintegrate and fail, FlexPro offers 40 years of Weather-Tite™ performance. Its specially formulated polyester—manufactured from recycled material—prevents moisture absorption and holds together to keep out pests. It’s also extremely durable, flame-resistant, clog-resistant and tear-resistant.

How To Install

With FlexPro, which comes 75 feet to a box in twenty-five 3-foot sections, one size fits most panels. To install FlexPro, simply peel and stick the product to the metal roof, careful to match the custom-cut contours to roof ridges. Next, put the ridge cap in place and fasten down-slope from the FlexPro product.

Step 1

FlexPro comes in various panel configurations a well as roll and stick package options. Apply the FlexPro Ridge Vent to metal roof by removing the backing paper.

Step 2

Align the FlexPro Ridge Vent 1/2”-1” up-slope from the edge of the ridge cap. Place onto metal roof with adhesive side down. Note that the adhesive is strong and once put in place it will be hard to move. Be sure the FlexPro Ridge Vent is in place the first time.

Step 3

When attaching consecutive FlexPro Vents, butt fit the pieces together. Marco’s Weather-Tite Metal Roof Sealant can be used to seal the butt joint. Place ridge cap over FlexPro. Secure in place with Marco QuickGrip™/QuickDrill™ fasteners; fasten through the metal roof ridge locations using a min. 3300 rpm screw gun, avoiding penetrating the FlexPro material.
