A watertight, integrated wall and roof expansion joint seal system includes an expansion joint seal for a structure. The seal includes a central portion having an underside and at least one central chamber disposed around a centerline, a first flange portion extending outwardly from the centerline and a second flange portion extending outwardly from the centerline in a direction opposite the first flange portion. The expansion joint seal includes a fold including a first fold portion and a second fold portion, wherein the first fold portion of the first flange portion is attachable to a first surface of a first substrate of the structure and the second fold portion of the first flange portion is attachable to a second surface of a the first substrate, and the first fold portion of the second flange portion is attachable to a first surface of a second substrate of the structure and the second fold portion of the second flange portion is attachable to a second surface of the second substrate, such that the central portion is disposed within and seals a gap formed between the first substrate and the second substrate of the structure. The system further includes a joint closure.

A watertight, integrated wall and roof expansion joint seal system comprising: a) an expansion joint seal for a structure, the seal comprising:a central portion having an underside and including a sidewall comprising members, the sidewall configured to define at least one central chamber disposed around a centerline;a first flange portion extending outwardly from the centerline; anda second flange portion extending outwardly from the centerline in a direction opposite the first flange portion;wherein at least one of the first flange portion and the second flange portion is bifurcated into an upper flange portion and a lower flange portion, the upper flange portion extending further in length from the centerline than the lower flange portion, and the lower flange portion being substantially parallel to the upper flange portion, the thickness of each of the upper flange portion and the lower flange portion being planar and substantially the same as the thickness of the members of the sidewall;a fold comprising a first fold portion and a second fold portion,wherein the first fold portion of the first flange portion is attachable to a first surface of a first substrate of the structure and the second fold portion of the first flange portion is attachable to a second surface of the first substrate, and the first fold portion of the second flange portion is attachable to a first surface of a second substrate of the structure and the second fold portion of the second flange portion is attachable to a second surface of the second substrate, such that the central portion is disposed within and seals a gap formed between the first substrate and the second substrate of the structure; andb) a joint closure comprising a core and a layer of elastomer disposed on the core, the joint closure further comprising an end portion configured to match and integrate with the underside of the central portion to form the watertight, integrated wall and roof expansion joint system;wherein movement of one or both of the first substrate and the second substrate causes a response in the central portion to maintain the seal. 2. The watertight, integrated wall and roof expansion joint seal system of claim 1, wherein at least one of the first flange portion and the second flange portion is comprised of a flexible material such that the at least one of the first flange portion and the second flange portion may be affixed to the structure at an angle or an elevation that differs from the central portion. 3. The watertight, integrated wall and roof expansion joint seal system of claim 1, further including a bracket disposed between the upper flange portion and the lower flange portion to facilitate mounting of the expansion joint seal to the structure. 4. The watertight, integrated wall and roof expansion joint seal system of claim 1, wherein when installed the upper flange portion and the lower flange portion interlay with two or more layers of roofing materials. 5. The watertight, integrated wall and roof expansion joint seal system of claim 1, wherein expansion of at least one of the first substrate and second substrate causes the central portion to deflect upward such that the central portion does not impinge on itself or prevent movement of one or both of the first substrate and the second substrate while maintaining the seal. 6. The watertight, integrated wall and roof expansion joint seal system of claim 1 wherein contraction of at least one of the first substrate and the second substrate causes the central portion to deflect downward such that the central portion does not impinge on itself or prevent movement of one or both of the first substrate and the second substrate while maintaining the seal. 7. The watertight, integrated wall and roof expansion joint seal system of claim 1 wherein the central portion includes a sidewall, the sidewall configured to define the at least one central chamber, the at least one central chamber being configured to be selectively collapsible in response to a force from movement of one or both of the first substrate and the second substrate. 8. The watertight, integrated wall and roof expansion joint seal system of claim 7 wherein the at least one central chamber is comprised of at least one pair of central chambers disposed about the centerline. 9. The watertight, integrated wall and roof expansion joint seal system of claim 1 wherein the at least one central chamber is comprised of an odd number of central chambers. 10. The watertight, integrated wall and roof expansion joint seal system of claim 1, wherein the core comprises open celled foam comprising a plurality of individual laminations assembled to construct a laminate, one or more of the laminations being infused with at least one of a fire retardant material and an acrylic, and a layer of elastomeric coating is located on the core. 11. The watertight, integrated wall and roof expansion joint seal system of claim 10, wherein the core comprises an elongated section comprising a horizontal setback portion configured to bridge a gap between a structural wall and a façade. 12. The watertight, integrated wall and roof expansion joint seal system of claim 11, wherein the elongated section comprises an elastomeric coated 45 degree miter. 13. An expansion joint seal system for a structure, comprising: a) an expansion joint seal comprising:a central portion including a sidewall comprising members, the sidewall configured to define at least one central chamber disposed around a centerline;a first flange portion extending outwardly from the centerline; anda second flange portion extending outwardly from the centerline in a direction opposite the first flange portion;wherein at least one of the first flange portion and the second flange portion is bifurcated into an upper flange portion and a lower flange portion, the upper flange portion extending further in length from the centerline than the lower flange portion, and the lower flange portion being substantially parallel to the upper flange portion, the thickness of each of the upper flange portion and the lower flange portion being planar and substantially the same as the thickness of the members of the sidewall;a fold comprising a first fold portion and a second fold portion,wherein the first fold portion of the first flange portion is attachable to a first surface of a first substrate of the structure and the second fold portion of the first flange portion is attachable to a second surface of the first substrate, and the first fold portion of the second flange portion is attachable to a first surface of a second substrate of the structure and the second fold portion of the second flange portion is attachable to a second surface of the second substrate, such that the central portion is disposed within and seals a gap formed between the first substrate and the second substrate of the structure; andb) a watertight barrier located beneath the central portion and between the first substrate and the second substrate forming a watertight seal between the first substrate and the second substrate;wherein movement of one or more of the first substrate and the second substrate causes a response in the central portion and in the watertight barrier to maintain the seal. 14.
