Silicone roof edge accessory for foam roof and associated method
View Patent ↗A foam roof of the present disclosure includes a roof having a roof portion with one of an edge, termination, or penetration having a generally upright edge. A foam is received over a region of the roof portion adjacent to and along the generally upright edge. A flexible edge member is received over the generally upright edge and an adjacent region of the foam. The edge member preferably has first and second legs disposed in substantially perpendicular relation, and each leg has a variable or tapering cross-sectional conformation.
1. A foam roof including:
a roof includes a roof portion including one of an edge, termination, or penetration having a generally upright edge;
a foam received over a region of the roof portion adjacent to and along the generally upright edge;
a silicone material edge member received over the generally upright edge and an adjacent region of the foam; and
a silicone adhesive sealant received on a surface of the foam and solely securing the edge member to the foam; wherein a second leg of the edge member tapers inwardly toward the generally upright edge of the roof portion, away from a first leg.
2. The foam roof of claim 1 wherein the edge member has a generally longitudinal, first portion of variable cross-section that increases in thickness as the edge member extends toward the generally upright edge.
3. The foam roof of claim 2 wherein the edge member first portion has a tapering cross-sectional conformation.
4. The foam roof of claim 2 wherein the edge member first portion has a width of approximately two inches.
5. The foam roof of claim 1 wherein the edge member has first and second legs disposed in substantially perpendicular relation.
6. The foam roof of claim 1 wherein the edge member has an extrudable profile that exhibits at least one of flexibility (up to 700% elongation) and high strength (1600 psi tensile strength).
7. The foam roof of claim 1 further comprising a top coat received over a portion of the edge member.
8. A foam roof including:
a roof portion including one of an edge, termination, or penetration having a generally upright edge;
a foam received over a region of the roof portion adjacent to and along the generally upright edge; and
an edge member received over the generally upright edge and an adjacent region of the foam, wherein the edge member has first and second legs disposed in substantially perpendicular relation and the first leg increases in cross-sectional thickness as the first leg extends toward the second leg.
9. The foam roof of claim 8 wherein the second leg increases in cross-sectional thickness as the second leg extends toward the first leg.
10. The foam roof of claim 8 further including a sealant interposed between the edge member and the foam.
11. The foam roof of claim 10 wherein the edge member is a silicone material.
12. The foam roof of claim 11 wherein the sealant is a silicone adhesive.
13. The foam roof of claim 8 wherein the edge member is a silicone material.
14. The foam roof of claim 8 wherein the second leg of the edge member tapers inwardly toward the generally upright edge of the roof portion.
15. A method of forming a foam roof on a roof surface comprising:
mounting a foam stop on the roof surface;
applying a foam over preselected regions of the roof surface, including over an upper surface of the foam stop;
installing a silicone material edge member, wherein the edge member has first and second legs disposed in substantially perpendicular relation to one another, over a preselected portion of the foam and foam stop, including orienting a first leg of the edge member over the preselected portion of the foam where the first leg increases in cross-sectional thickness as the first leg proceeds toward the second leg, and positioning the second leg of the edge member adjacent a vertically extending portion of the foam stop; and
adhering the first leg of the silicone edge member to the foam with a silicone adhesive sealant
applying a top coat over at least a portion of an upper surface of the edge member and at least a portion of the foam adjacent the edge member.
16. The method of claim 15 further comprising applying a top coat over at least a portion of an upper surface of the edge member and at least a portion of the foam adjacent the edge member.
17. The method of claim 15 further including tapering the 2 nd leg of the edge member inwardly toward the vertically extending portion of the foam stop.
