Expert Verdict — Reviewed by the SuperArbor Pro Desk
Silicone is the go-to chemistry for restoring aged single-ply and asphalt membranes because it tolerates ponding water well. Verify the membrane is clean, dry, and compatible before application, and use JM's reinforcing fabric at seams and penetrations for best results. Choose a white finish where reflectivity and energy savings matter.
Wear appropriate PPE and follow the manufacturer's safety data sheet when handling and applying roof coatings.
Order the Johns Manville JM Coating Silicone 5-gallon white pail for your next roof restoration.
