Mastic Sealant

Mastic is a popular and versatile sealant choice that works effectively as an adhesive in construction projects. Mastic sealant can be used to create a durable, flexible and waterproof seal on many different materials. For certain exterior jobs, including some roofing tasks where a paintable surface might be required, mastic can provide a reliable seal, acting as an effective roofing sealant.

Silicone Sealant

Silicone sealant is a durable and long-lasting adhesive that works well for many different construction applications, proving particularly effective as a roofing sealant. Specifically, roofing silicone formulations are designed to offer exceptional weather resistance and UV stability. They remain highly flexible even under extreme temperatures, making roofing silicone ideal for sealing joints on various roof types, around skylights, flashing, and guttering. This type of roofing silicone quickly creates a durable, water-tight seal to ensure your roof remains weatherproof and protected for years to come. While excellent for general sealing like around windows, the robust properties of roofing silicone make it a top-tier choice for demanding outdoor and roofing applications.
