ABSTRACT:
A weather seal for expandable roof joints or roof-to-wall joints is provided with an elastomeric outer seal, retaining means for receiving flashing or portions of the building structure, and further for receiving a clamping bar and continuously applied sealant material. The weather seal is further provided with means for retaining insulation/support material against the inner surface of the elastomeric outer seal. An inner membrane, or gutter member, may be positioned within the joint and affixed to the structure sections between the elastomeric outer seal to provide improved imperviousness of the weather seal. Flashing material may be appropriately shaped to receive portions of the weather seal for securing the weather seal in place of the clamping bar.
