Abstract:
The present invention discloses about polymer shingles used as a roofing sheet or a waterproof membrane comprises a felt of a particular characteristic and of different thicknesses for providing strength to the shingles as per consumers specific needs. One or more layers of polymer and primer is applied on the felt, thereby facilitating bonding of the several layers of the shingles. Further cement additives such as Portland cement or calcium cement additive are selectively used depending on the quality of the shingle that is required to manufacture the polymer shingles to act as waterproof membrane. Further, applying ceramic granules onto the cement additive and are then compressed with a roller to ingrain them in the polymer layer to be used a weather proof and durable roofing sheet.

Claim (Index 9):
A method for preparing a roofing sheet comprising:\n preparing and adhering a first layer of felt of weight at least 3.5 ounce per square yard to a non-woven textile fabric to form a non-woven geo-textile fabric; adhering a second layer of primer mixed with fire and flame resistant additive to the non-woven geo-textile fabric; adhering a third layer of polymer mix with fire and flame resistant additives and cement additives to the second layer of primer at constant supply of air pressure, wherein the third layer of polymer mix is allowed to dry; adhering a fourth layer of polymer mix with fire and flame resistant additives and cement additives to the third layer of primer at constant supply of air pressure, wherein the fourth layer of polymer mix is allowed to dry; and adhering a top layer of ceramic granules on the fourth layer of polymer mix, wherein the ceramic granules are bonded using a cement additive, further the granules are compressed with a roller to ingrain the granules in the fourth layer of polymer mix, further desired color pigments can be added to the primer of the second layer, polymer mix of the third and fourth layer and additives of the top layer to have desired coloring of the roofing sheet.
