Re-roofing method and apparatus

Abstract

A spacer for applying a corrugated metal panel atop a roof covered by a number of rows of shingles. The spacer includes a strip of resilient foam having a width sufficient to rest flush against the exposed portion of one of the rows of shingles without overlapping adjacent rows and having a height sufficient to project above the tops of the shingles in adjacent rows. In use, a pair of spacers are positioned along two rows of shingles. Then, a corrugated metal panel is positioned atop the pair of spacers and is attached to the roof by means of a penetrating fastener.

1 . A spacer for applying a corrugated metal panel atop a roof covered by a plurality of rows of shingles, said spacer comprising a strip of resilient foam having a width sufficient to rest flush against the exposed portion of one of the rows of shingles without overlapping adjacent rows and having a height sufficient to project above the tops of the shingles in adjacent rows.  
   
   
       2 . The spacer according to  claim 1  wherein said resilient foam comprises polyethylene.  
   
   
       3 . The spacer according to  claim 1  wherein said strip of resilient foam can be formed into a roll for convenient storage and transport prior to use.  
   
   
       4 . The spacer according to  claim 1  having a width of about 3 inches and a height of about ¼ inch.  
   
   
       5 . A method for re-roofing a roof having multiple rows of asphalt shingles, said method comprising the steps of: 
 positioning a first strip of resilient foam atop the exposed portion of one row of asphalt shingles, said first strip of resilient foam having a height sufficient to project above the tops of the shingles in adjacent rows;    positioning a second strip of resilient foam atop the exposed portion of another row of asphalt shingles, said second strip of resilient foam having a height sufficient to project above the tops of the shingles in adjacent rows;    positioning a corrugated metal panel atop said first strip of resilient foam and said second strip of resilient foam; and,    driving a penetrating fastener through said corrugated metal panel so as to attach said corrugated metal panel to the roof.    
   
   
       7 . A roof, comprising: 
 a joist;    a deck supported by said joist;    an underlayment positioned atop said deck;    a plurality of rows of shingles positioned atop said underlayment;    a resilient spacer positioned atop one of said rows of shingles and projecting above adjacent rows of shingles; and,    a corrugated metal roof panel positioned atop said resilient spacer and separated from said rows of shingles by said spacer.
