Low slope roofing system
View Patent ↗A roofing system, comprising: at least one strap spaced on centers horizontally up the slope of a roof deck; at least one bead of adhesive applied to the at least one strap; at least two metal roofing panels placed on the at least one bead of adhesive applied to the at least one strap; and at least two fasteners attached to the at least two metal roofing panels and into the roof deck at a top and perimeter of the at least two metal roofing panels.
1. A roofing system, comprising:
at least two straps extending horizontally and spaced from each other in a direction up the slope of a roof deck;
at least two nail fasteners attached to the at least one strap and into the roof deck, wherein a head of each of the nail fasteners is above at least one strap and a shaft of each of the nail fasteners is driven through the strap and into the roof deck;
at least one bead of adhesive applied above the at least one strap; and
at least two metal roofing panels placed on the at least one bead of adhesive applied above the at least one strap, wherein the at least two metal roofing panels are above the at least two nail fasteners and the at least two nail fasteners do not penetrate the at least two metal roofing panels.
2. A roofing system as in claim 1 , wherein the at least one strap spaced horizontally up the slope of a roof desk is steel strapping.
3. A roofing system as in claim 1 , wherein the at least one strap spaced horizontally up the slope of a roof deck is attached with ring shank roofing nails.
4. A roofing system as in claim 3 , wherein the ring shank roofing nails are between 6 and 8 inches on center.
5. A roofing system as in claim 1 , wherein the at least one strap is at least two straps that are spaced between 16 and 24 inches on centers horizontally up the slope of the roof desk.
6. A roofing system as in claim 1 , further comprising trim along at least one edge of each of the at least two metal roofing panels, wherein the trim is attached along the at least one edge of each of the at least two metal roofing panels.
7. A roofing system as in claim 1 , further comprising an underlayment layer under the at least one strap and above the roof deck.
8. A roofing system as in claim 1 , wherein the at least one strap has a length that is positioned perpendicular to a length of a base sheet and spaced at a predetermined length on center.
9. A roofing system as in claim 1 , wherein at least one strap is attached by at least two fasteners placed in two rows at a predetermined length on center along the strap.
10. A roofing system as in claim 9 , wherein at least one of the two rows of fasteners is fastened into a wood support of the roof deck.
11. A roofing system as in claim 1 , wherein the adhesive is a urethane adhesive and sealant.
12. A roofing system as in claim 1 , wherein the at least two fasteners are in withdrawal and not in shear.
13. A roofing system as in claim 1 , wherein the at least one strap is tensile steel with a corrosion resistant barrier coating.
14. A roofing system as in claim 7 , wherein the at least one strap is at least two straps placed perpendicular to a length of the underlayment layer and spaced a predetermined length on center.
15. A roofing system as in claim 1 , wherein the adhesive is a foam adhesive.
16. A roofing system as in claim 1 , wherein the at least one strap is rolled tensile steel.
17. A roofing system as in claim 1 , wherein the at least one strap has markings to designate a gun nail for nailing on center fastener target locations.
