Self-seal ring for roofing nail

Abstract

A self-seal ring for creating a water tight seal around a nail used in affixing a roof shingle, underlayment and insulation to a roof deck. Also disclosed is a method for installing the self-seal ring and nail to the underlying support.

1 . A self-seal ring for creating a water-tight seal around roof nails, comprising: 
 1) a ring-like pad having a center base having a bore therein that fits around a nail having a stem and a head, said ring-like pad having an upper surface and a lower surface;    2) a layer of adhesive optionally applied to said upper surface and said lower surface; and    3) a release liner applied upon said adhesive layers.    
     
     
         2 . The self-seal ring of  claim 1  wherein the head of said nail covers said bore to prevent the entering of moisture into an underlying deck.  
     
     
         3 . The self-seal ring of  claim 1  wherein said adhesive is selected from the group consisting of: polyisobutanes, polybutanes, polyisoprene butyl rubber, styrene-isoprene-styrene, styrene-butadiene-styrene, styrene-ethylene-butadiene-styrene, acrylics, polyurethanes, atacticpolypropylene or mixtures thereof.  
     
     
         4 . The self-seal ring of  claim 1  wherein said release liner is selected from the group consisting of waxed paper, polycoated paper, film-based paper and plastic.  
     
     
         5 . The self-seal ring of  claim 1  having a size the diameter of which is from about 0.5 inches to about 2.0 inches.  
     
     
         6 . The self-seal ring of  claim 1  comprising: 
 of about 50% to about 75% w/w of asphalt;    of from about 25% to about 40% w/w of a filler; and    of from about 1% w/w to about 5% w/w of a modifier selected from the group consisting of styrene-butadiene-styrene, polybutane and polybutylene and mixtures thereof.    
     
     
         7 . The self-seal ring of  claim 6  wherein said ring comprises 60ˆ to 70% w/w asphalt.  
     
     
         8 . The self-seal ring of  claim 1  having a thickness in the range of 0.5 inches to 4.0 inches.  
     
     
         9 . A method for preparing a self-seal ring comprising the steps of: 
 mixing an asphalt, filler and modifier to form a mixture;    placing the mixture in a roller machine to produce a film;    conditioning the film at about 40° F.;    cutting the film with a die to the desired specification; and    puncturing the center with a heated element to allow for the insertion of a nail.    
     
     
         10 . A method of installing a self-seal ring with a nail therein into an underlayment, roof shingle and roof deck comprising the steps of: 
 fitting the self-seal ring around a nail;    positioning the self-seal ring with the nail therein onto said underlayment, roof shingle and roof deck;    applying pressure on the self-seal ring and nail so that the nail punctures the shingle, underlayment and roof deck.    
     
     
         11 . The method of installing a self-seal ring with a nail therein comprising: 
 a) a self-seal ring comprising a pad having a center bore that fits around the nail, said nail having a stem and a head, said pad having an upper surface and a lower surface;    b) a layer of adhesive optionally applied to said upper surface and to said lower surface; and    c) a release liner applied upon said adhesive layers;    the method comprising the steps of:    positioning the nail into the pad around the nail;    positioning said pad with the nail therein comprising a roof shingle, insulation, and underlayment;    removing said liner comprising the adhesive and inserting and pressing said nail into a substrate comprising a roof shingle, insulation and underlayment into a substrate to create a tight seal around the nail.    
     
     
         12 . The method of  claim 11  wherein said adhesive is selected from the group consisting of: polyisobutanes, polybutanes, polyisoprene, butyl rubber, styrene-isoprene-styrene, styrene-butadiene-styrene, styrene-ethylene-butadiene-styrene, acrylics, polyurethanes, atactic polypropylene or mixtures thereof.  
     
     
         13 . The method of  claim 12  wherein the release liner is selected form the group consisting of waxed paper, polycoated paper, film-based paper and plastic.  
     
     
         14 . The method of  claim 12  wherein the release liner has a thickness in the range of 2 to 9 mils.  
     
     
         15 . The method of  claim 9  wherein the self-seal ring is made by: 
 mixing an asphalt, a filler and a modifier to form a mixture;    placing the mixture in a roller machine to produce a film;    conditioning the film at about 40° F.;    cutting the film with a die to the desired specification; and    puncturing the center with a heated element to allow for the insertion of a nail.
