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 1):
A roofing sheet comprising:\n a non-woven textile fabric that is one of (a) a felt layer and (b) a felt adhered to the non-woven textile fabric to form a non-woven geo-textile fabric; a second layer comprising primer adhered over the non-woven geo-textile fabric; a third layer comprising a polymer mixed with cement additives adhered over the second layer; and a fourth layer comprising a polymer mixed with cement additives adhered over the third layer; and a top layer adhered to the fourth layer wherein said top layer comprises ceramic granules, wherein the ceramic granules are bonded using said cement additive and wherein the granules are compressed with a roller to ingrain said granules in the polymer of an adjacent layer.
