Expert Verdict — Reviewed by the SuperArbor Pro Desk
Cant strips are a small cost that protects the most failure-prone area of a low-slope roof: the 90-degree deck-to-wall transition. Install them tight to the wall and deck with no gaps before membrane application so the base flashing follows a smooth 45-degree angle. Match cant height to the system specification rather than defaulting to size.
Handle mineral wool strips with gloves and long sleeves to avoid skin irritation from fibers.
Order Soprema Soprarock 1.5 in. x 4 in. cant strips for a proper membrane transition at every perimeter.
