Collection: Roofing Sealants
Legacy Pro’s exterior sealants deliver maximum adhesion, UV resistance, flexibility, and long-term durability across shingles, metal flashings, vents, roof boots, skylights, and roof transitions.
HP4 Hybrid Polymer Exterior Sealant is our recommended solution for most roofing and flashing applications due to its multi-substrate compatibility and weatherproof performance. For skylight and glazing interfaces, HP3 100% Silicone Exterior Sealant provides a UV-stable, high-adhesion option for glass-to-metal and glass-to-frame joints.
Built on experience. Engineered for performance.
