Metal roof system

Abstract

The present invention generally relates to metal roofs. In one aspect, a method of placing a roof system over an existing low sloped roof is provided. The method includes measuring a slope of the existing low sloped roof to determine the location of irregularity points. Thereafter, at least one shim member is placed proximate each irregularity point and at other predetermined locations. Next, an airspace is formed between the existing low sloped roof and the roof system and then the roof system is operatively attached to the existing low sloped roof.

1 . A method of placing a roof system over an existing low sloped roof comprising: 
 measuring a slope plane of the existing low sloped roof to determine the location of irregularity points;    placing at least one shim member proximate each low irregularity point and at other predetermined locations;    forming an airspace between the existing low sloped roof and the roof system; and    operatively attaching the roof system to the existing low sloped roof.    
   
   
       2 . The method of  claim 1 , further including securing a clip member on top of the at least one shim member to attach a plurality of roof panels of the roof system to the existing low sloped roof.  
   
   
       3 . The method of  claim 2 , wherein the plurality of roof panels are continuous from a ridge to an eave of the roof system.  
   
   
       4 . The method of  claim 2 , wherein the plurality of roof panels are constructed and arranged to ensure the last roof panel lands at a predetermined distance from a penetration or a wall.  
   
   
       5 . The method of  claim 2 , further including raising the perimeter of the roof system to create a weatherproof relationship between the roof system and a building or a structure below.  
   
   
       6 . The method of  claim 5 , wherein an extension member is placed on top of a panel seam of the roof panel to raise the perimeter of the roof system.  
   
   
       7 . The method of  claim 6 , further including creating a sealing relationship between the extension member and the panel seam.  
   
   
       8 . The method of  claim 1 , further including reducing the heat transfer between the roof system and a building or a structure below by utilizing the air space.  
   
   
       9 . The method of  claim 8 , further including placing a radiant barrier in the airspace.  
   
   
       10 . The method of  claim 1 , further including running a plurality of roof panels on an uphill side of a large penetration, wherein the roof panels are perpendicular to the slope.  
   
   
       11 . The method of  claim 10 , further including raising the plurality of roof panels on the uphill side of the large penetration.  
   
   
       12 . A method of placing a roof system over an existing low sloped roof comprising: 
 placing at least one shim member proximate each low irregularity point on the existing low sloped roof and at other predetermined locations;    reducing the heat transfer from the roof system to a building or structure below by forming an air space between the roof system and the existing low sloped roof; and    operatively attaching the roof system to the existing low sloped roof.    
   
   
       13 . The method of  claim 12 , further including directing the thermal movement of the roof system by employing a plurality of fixed and floating clips between the roof system and the existing low sloped roof.  
   
   
       14 . The method of  claim 12 , further including raising the perimeter of the roof system to create a weatherproof relationship between the roof system and a building or a structure below.  
   
   
       15 . The method of  claim 12 , wherein the roof system includes a plurality of roof panels which are continuous from a ridge to an eave.  
   
   
       16 . The method of  claim 15 , wherein the plurality of roof panels are constructed and arranged to ensure the last roof panel lands at a predetermined distance from a penetration or a wall.  
   
   
       17 . A method of placing a roof system over an existing low sloped roof comprising: 
 measuring a slope plane of the existing low sloped roof to determine the location of irregularity points;    placing at least one shim member proximate each low irregularity point and at other predetermined locations;    directing the thermal movement of the roof system by employing a plurality of fixed and floating clips at predetermined locations between the roof system and the existing low sloped roof; and    operatively attaching the roof system to the existing low sloped roof.    
   
   
       18 . The method of  claim 17 , further including forming an air space between the existing low sloped roof and the roof system.  
   
   
       19 . The method of  claim 17 , wherein the roof system includes a plurality of roof panels which are continuous from a ridge to an eave.  
   
   
       20 . A member for use with a roof system, the member comprising a plate member constructed and arranged to raise the roof system relative to an existing low sloped roof and to fill a low irregularity point on the existing low sloped roof.
