Expert Verdict — Reviewed by the SuperArbor Pro Desk
Perlite tapered edge strips like this 1 in. x 24 in. Lucas Specialty Rock strip create a gradual transition at roof edges to reduce membrane stress and eliminate a hard insulation step. Order by perimeter: 72 lf per bundle covers a typical small-to-mid roof edge with a few bundles. Coordinate thickness with adjacent insulation board so the taper lands flush with the finished membrane elevation.
Handle perlite boards carefully to avoid breakage and wear gloves, eye protection and dust protection when cutting roof insulation.
