Silicone-based Sealants

Silicone sealants are known for their excellent flexibility and durability. They can withstand extreme weather conditions and UV exposure, making them ideal for various roofing materials, including metal, tile, and asphalt shingles. Their ability to expand and contract with temperature changes helps maintain a strong seal over time.

Polyurethane Sealants

Polyurethane sealants provide robust adhesion and are particularly effective for sealing roof joints and seams. They are resistant to water, chemicals, and physical wear, ensuring a long-lasting seal. This type of sealant is often used in commercial roofing but is also suitable for residential applications.

Acrylic Sealants

Acrylic sealants are a popular choice for their ease of application and cost-effectiveness. They are UV-resistant and provide good protection against water infiltration. Acrylic sealants are especially suitable for flat roofs and can be applied with a brush or sprayer.
