A method is presented for extending the lives of existing slate, fibrous cement and clay tile roofs. The method involves injecting an especially formulated, polymer material into the spaces and voids of adjoining tiles. The injection process uses pumping equipment with a custom-designed gasket at the spray gun's point of application to aid in directing the grout into the spaces and voids.

1. A process for preserving and extending the life of an existing roof comprised of roofing elements and joints between said elements, said roofing elements chosen from the group consisting of slates and fibrous cement or clay tiles, said process comprising the steps of:injecting a polymer grout into the spaces and voids between the joints of roofing elements of said existing roofing, and performing said injecting step with the use of injection equipment that is equipped with a gasket at the equipment's exit to aid in directing said grout into said spaces and voids. 2. The process as recited in claim 1, further comprising the steps of:prior to injecting said grouting material, preparing the surface of said roof by powerwashing said roof. 3. The process as recited in claim 2, further comprising the steps of:prior to injecting said grout, preparing the surface of said roof by replacing any damaged roofing elements that affect the water proofing characteristics of said roof. 4. The process as recited in claim 3, wherein said grout is a specially formulated, water-based mixture comprising materials chosen from the group consisting of acrylic polymer, antibiological agents, and pulverized slate, and with the chosen materials being mixed in proportions so as to yield desired physical properties of said grout.5. The process as recited in claim 1, wherein said gasket is made from a foam material of specified density and has a front face surface that is concave.6. The process as recited in claim 2, wherein said grout is a specially formulated, water-based mixture comprising materials chosen from the group consisting of acrylic polymer, antibiological agents, and pulverized slate, and with the chosen materials being mixed in proportions so as to yield desired physical properties of said grout.7. The process as recited in claim 6, wherein said gasket is made from a foam material of specified density and has a front face surface that is concave.8. The process as recited in claim 2, wherein said gasket is made from a foam material of specified density and has a front face surface that is concave.9. The process as recited in claim 1, further comprising the steps of:prior to injecting said grout, preparing the surface of said roof by replacing any damaged roofing elements that affect the water proofing characteristics of said roof. 10. The process as recited in claim 9, wherein said grout is a specially formulated, water-based mixture comprising materials chosen from the group consisting of acrylic polymer, antibiological agents, and pulverized slate, and with the chosen materials being mixed in proportions so as to yield desired physical properties of said grout.11. The process as recited in claim 1, wherein said grout is a specially formulated, water-based mixture comprising materials chosen from the group consisting of acrylic polymer, antibiological agents, and pulverized slate, and with the chosen materials being mixed in proportions so as to yield desired physical properties of said grout.12. The process as recited in claim 11, wherein said gasket is made from a foam material of specified density and has a front face surface that is concave.
