Expert Verdict — Reviewed by the SuperArbor Pro Desk
Choose Vycor Ultra when the deck will see high surface temperatures or reactive metals—copper, zinc, COR-TEN—where asphaltic membranes can bleed or bond. Roll it onto a clean, dry deck at 40°F or warmer for best adhesion, or prime per manufacturer guidance in cold weather. Keep a half-lap consistent and roll the laps firmly to activate the butyl bond.
Self-adhered membranes are slippery, especially with dust or moisture—walk carefully and wear proper footwear on the roof.
