Single Ply Roofing System

Abstract

A roofing system for application on a roofing substrate wherein flexible supports alleviate fatiguing of the roofing sheeting which typically occurs due to thermal expansion and contraction, thus enabling thicker roofing sheeting to be used and thus extending the usable life of the roofing sheeting.

1 . A flashing that provides a water-resistant seal comprising:
 a lower flashing component; and   an upper flashing component, wherein a lower portion of said upper flashing component is wrapped at least partially around and is slidably connected to an upper portion of said lower flashing component, thereby providing a water-resistant seal.   
   
   
       2 . The flashing of  claim 1  wherein said lower flashing component is secured to a roofing material. 
   
   
       3 . The flashing of  claim 2  further comprising a waterproofing material disposed between said lower flashing component and said roofing material. 
   
   
       4 . The flashing of  claim 2  wherein said roofing material comprises sheeting. 
   
   
       5 . The flashing of  claim 4  wherein said sheeting comprises metal sheeting. 
   
   
       6 . The flashing of  claim 2  further comprising a support wherein said roofing material is disposed on top of said support. 
   
   
       7 . The flashing of  claim 6  wherein said support comprises a flexible material. 
   
   
       8 . The flashing of  claim 7  further comprising insulating material, wherein said support is abutted next to said insulating material. 
   
   
       9 . The flashing of  claim 1  wherein an upper portion of said lower flashing component comprises an acute angle bend such that the bend resides above that portion which is wrapped at least partially within said upper flashing component when said flashing is in an installed position. 
   
   
       10 . The flashing of  claim 1  wherein said lower flashing component is disposed on an end portion of said roofing material. 
   
   
       11 . The flashing of  claim 1  wherein said upper flashing component is attached to a wall. 
   
   
       12 . The flashing of  claim 11  further comprising a waterproofing material disposed between said upper flashing component and the wall. 
   
   
       13 . A flashing that provides a water-resistant seal comprising:
 a first end portion of a first component, wherein said first end portion comprises an acute angle and wherein a tip of said first end portion resides within an inner portion of a curved portion of a first end portion of a second component;   a second end portion of said first component, wherein said second end portion is securable to a roofing material; and   a second end portion of said second component, wherein said second end portion is securable to a wall.   
   
   
       14 . The flashing of  claim 13  wherein the roofing material and the wall form an angle of about 90 degrees. 
   
   
       15 . The flashing of  claim 13  further comprising waterproofing material disposed between said second end portion of said first component and the roofing material. 
   
   
       16 . The flashing of  claim 13  wherein the roofing material comprises sheeting. 
   
   
       17 . The flashing of  claim 16  wherein the sheeting comprises metal sheeting. 
   
   
       18 . The flashing of  claim 13  further comprising waterproofing material disposed between said second end portion of said second component and the wall. 
   
   
       19 . A water-resistant flashing system comprising:
 upper and lower flashing components; and   bends disposed in said upper and said lower flashing components such that said components hook together and are slidable with respect to one another.   
   
   
       20 . The water-resistant flashing system of  claim 19  wherein water attempting to penetrate therebetween would have to make a plurality of turns.
