Expert Verdict — Reviewed by the SuperArbor Pro Desk
On low-slope commercial jobs, Paragon MOD Base gives you a rubberized asphalt ply that can start the assembly or fill interply positions, letting you tune a 2-4 ply system to budget. Confirm the deck and application method first: hot asphalt, cold adhesive and torch are each acceptable, but laps and mopping rates must follow Malarkey's system details. Pair it with a matching Paragon MOD cap sheet for a complete warrantable-style assembly, and order rolls based on net coverage after lap deductions.
Hot asphalt and torch application are fire hazards; use trained crews with proper PPE and fire watch per job-site safety requirements.
