         8 . The lap trim system of  claim 1 , wherein the pair of flanges are polyurethane. 
     
     
         9 . The lap trim system of  claim 6 , further comprising caulk between a top joint of the pair of flanges and the at least one piece of the plurality of pieces of siding. 
     
     
         10 . A lap trim system, the system comprising:
 an architectural shape to secure to a plurality of pieces of overlapping siding; and   at least one shoulder protruding from a rear surface of the architectural shape in profile, wherein the at least one shoulder is adapted to fit along a lower edge of at least one piece of the plurality of pieces of overlapping siding.   
     
     
         11 . A lap trim method, the method comprising:
 providing a composite material;   selecting a desired architectural shape for the composite material;   determining a siding width and spacing; and   configuring the composite material to form the selected architectural shape, wherein a rear surface of the architectural shape having at least one shoulder protruding from the rear surface of the architectural shape in profile, wherein the at least one shoulder is adapted to fit along a lower edge of at least one piece of a plurality of pieces of overlapping siding.   
     
     
         12 . The lap trim method of  claim 11 , further comprising forming a drainage channel between the rear surface of the architectural shape when installed over the plurality of pieces of overlapping siding. 
     
     
         13 . The lap trim method of  claim 12 , wherein the architectural shape is adapted to fit over an outside corner of the plurality of pieces of overlapping siding. 
     
     
         14 . The lap trim method of  claim 11 , wherein the architectural shape is adapted to fit over an inside corner of the plurality of pieces of overlapping siding. 
     
     
         15 . The lap trim method of  claim 11 , further comprising adhering the architectural shape to the plurality of pieces of overlapping siding with an adhesive. 
     
     
         16 . The lap trim method of  claim 11 , further comprising caulking between a top joint of the architectural shape and the at least one piece of the plurality of pieces of siding. 
     
     
         17 . The lap trim method of  claim 11 , wherein the architectural shape is comprised of polyurethane foam. 
     
     
         18 . The lap trim method of  claim 11 , wherein the architectural shape is a simulated shutter shape. 
     
     
         19 . The lap trim method of  claim 11 , wherein a longitudinal edge between the architectural shape and the at least one piece of the plurality of pieces of siding is watertight. 
     
     
         20 . The lap trim method of  claim 11 , further comprising securing a substantially horizontal band to the architectural shape, wherein the substantially horizontal band having at least one shoulder protruding from the rear surface in profile and the at least one shoulder adapted to fit along the lower edge of at least one piece of the plurality of overlapping siding.
