Expert Verdict — Reviewed by the SuperArbor Pro Desk
Tapered FESCO perlite board is a proven way to build slope into a low-slope roof without crickets at every condition. Order bundles by slope so the field tapers run consistently toward the drains, and verify the specific slope and taper callout on your project spec before ordering. Follow Johns Manville installation details for attachment to secure system warranty eligibility.
Handle and cut perlite board with gloves, eye protection and dust control, and follow OSHA practice and Johns Manville installation instructions on the roof.
